Method of manufacturing laminated sound absorbing material and method of constructing same

The present invention relates to a laminated sound absorbing material having a laminate composed of a sound absorbing paint or a sound absorbing putty, a method of manufacturing the same, and a method of manufacturing the same. More particularly, the present invention relates to a method of forming a laminate from the surface to the inner surface using a porous sound absorbing material And the porous sound absorbing material can be used to form the lamination from the surface to the outer surface direction.

The purpose of forming a laminate on a porous sound absorbing material is to provide a sound absorbing material suitable for various uses by diversifying the surface design and colors of the porous sound absorbing materials and improving them to new patterns, and to improve the sound absorbing performance, especially the low frequency sound absorption rate, And to provide a functional laminated sound absorbing material which improves the performance of the laminated sound absorbing material.

The present invention improves the problem of the conventional porous sound absorbing material used in the ceiling and the inner wall of the building, and the purpose of using the sound absorbing materials is for the purpose of adjusting the sound of building, sound absorption, interior finishing, interior finishing wall material, ceiling finishing material , And generally used forms are manufactured and supplied as a sound absorbing board, a sound absorbing tile, a sound absorbing felt, and a sound absorbing sheet.

The present invention is to provide a sound absorbing material having a layered structure of a conventional porous type absorption surface layer with a sound absorbing paint or a sound absorbing putty, a method of manufacturing the sound absorbing material, and a method of applying the same.

The materials constituting the sound absorbing materials are various and mostly composed of materials capable of forming an open porous shape to enhance sound absorption performance and manufacturing methods capable of forming an open porous shape.

Sound absorbing materials made of such materials and various manufacturing methods are classified into a woolen sound absorbing board (wood wool cement board), a melamine resin foaming sound absorbing board, an aluminum foaming sound absorbing board, a foam concrete sound absorbing tile or a sound absorbing block Cement-based lightweight foam-absorbing material), polyester sound absorbing board, coconut fiber sound-absorbing insulation material, natural pulp sponge, and three-dimensional metal mesh.

In the present invention, the sound-absorbing material is classified as a sound-absorbing material in the industry, and some materials are not used in the industry as a sound-absorbing material and are not used as a sound-absorbing material. However, .

The sound-absorbing materials show various disadvantages, and their use is limited, and there are many problems as interior lining materials.

In the above case, in the case of the wooly sound-absorbing board, when the wooly board is attached by a method of gluing to the installation surface by a method of gluing to the installation surface by a method of installing the wool-to-ceiling 0 mm, the sound absorption performance is insufficient, And the durability against humidity and temperature changes is weak, so that the corrugated fiber of the corners and the surface may be swollen or partially peeled off for a long period of time.

Also, when the clothes are worn on the wall, fluffs are formed on the clothes, and the clothes are not suitable for the wall close to the rough skin. As the hygienic and residential environmental problems, the spacing between the wood fibers and the fibers is too large (the size of the open pores in the wood-fired cement board varies somewhat depending on the manufacturer, 7mm, 3 ~ 9mm pores are formed.) It provides a habitat environment for cockroaches and other insects between the wools. It is structured to be difficult to remove when scattered suspended matter such as living dust is inserted and accumulated. As a design disadvantage, design improvement has not been achieved for a long time, and there have been cases where interior fabrics have been used with attachment.

The principle of sound absorption of porous sound absorbing material is that the sound wave propagates into a thin hole and the sound is damped as a part of sound energy is changed into thermal energy due to friction with the material constituting the material, So that excessive voids of the woolen board act to reduce the sound absorption performance.

However, the wool board is generally used because it is a material excellent in fire stability of semi-fireproof. In the present invention, it is possible to improve the above problems by providing a laminate with a sound absorbing paint or a sound absorbing putty.

In the case of the melamine resin foamed porous sound absorbing board, it has a fine mesh structure (microcellular three-dimensional network open cell structure) having a density of 9 to 11 kg / m 3 and a porosity of 90 to 95% When used, the surface may be damaged and the surface strength is not suitable for a single use because it has a sponge-like structure. Also, since the open pores with an excessively low density and an excess network form the entire sound absorbing body, There were disadvantages.

However, this is also generally used because it is a material excellent in fire stability of semi-fireproof. In the present invention, as a means for solving the problems of the melamine resin foamed sound absorbing board, a laminate of a sound absorbing paint or a sound absorbing putty is provided, To improve the low frequency sound absorption rate and to solve the above problems.

Urethane resin foamed porous sound absorbing board (open porous urethane foam foamed sponge) also has a fine mesh structure with a density of 30 to 40 kg / m 3 and its surface durability is poor, which can damage the surface when used for a long time. In addition, since the open pores having a low density and an excessive network structure form the entire sound absorbing body, there is a disadvantage that the low sound absorption rate is low.

In addition, since it is made of urethane resin which is vulnerable to fire and has a disadvantage in fire stability, the use amount thereof has been greatly reduced in recent years. In the present invention, the fire durability of the surface can be improved by forming a sound- Also, as a means for improving the above problems, the above problems can be solved by providing a laminate with a sound absorbing paint or a sound absorbing putty.

In the case of the above-described aluminum foamed sound absorbing board, a foamed aluminum board produced using waste aluminum is generally used in a density of 290-320 kg / m < 3 >, and the shape of the open pores and the closed pores are mixed. The diameter of the open pores varies depending on the foaming conditions 3 to 7 mm. This is disadvantage in that the color is not uniform due to the use of recycled materials, and when the thickness is increased in order to increase the sound absorption performance, the price of aluminum material is increased due to the lack of price competitiveness against the sound absorbing materials. .

Therefore, as a means for solving the above problems, it is possible to provide a laminate with a sound absorbing paint or a sound absorbing putty to uniformize hues, express various colors, increase sound absorption performance, and form a laminate with a warm texture.

In the case of the foamed concrete sound absorbing tile or the sound-absorbing block, the porosity of the open air bubble cavity is made 65 to 75% and the density is set to 240 to 280 kg / m 3 in order to maintain a proper sound absorption rate. And there is concern about the occurrence of dust.

Also, it is not suitable for the wall surface which comes close to the rough texture of the cement. However, the surface tactile feeling can be smoothly improved by the sound absorbing paint or the sound absorbing putty lamination, and the above problems can be solved.

In addition, the lightweight bubble absorbing material is suitable for the present invention because it has a low material cost composition and is excellent in the sculpture carving operation characteristic.

The above-mentioned polyester sound absorbing board is manufactured in various forms with various densities (45 kg / m 3 ~ 210 kg / m 3). Since polyester fibers are produced by a heat fusion method without a separate adhesive agent, great. However, since it is a petrochemical product, it is vulnerable to fire and poisonous gas of petrochemical is generated in case of fire. Also, when the recycled fiber is used for price competition, the chromaticity is not so good, and the polyester polyester sound-absorbing board is not often exposed to the naked eye.

This can cause problems when changing colors or requiring renovation work. In case of painting with general paint, it is not possible to conceal the color of the interior fabric by one painting (the water-based paint absorption characteristic of the fabric), and it is possible to conceal it with sufficient two times of painting. .

In addition, in the process of removing the interior fabric on the surface of the existing sound absorbing material and replacing the new fabric, when the polyester surface and the fabric are adhered with the adhesive and are torn out, the polyester fiber is swollen and the horizontal surface of the sound absorbing board can not be maintained, The reuse rate of the ester-absorbing material was further lowered, and the amount of petrochemical waste that was difficult to dispose of was increased.

Most of the sound absorbing materials using the interior fabrics (for the improvement of the design and the improvement of the surface durability, as the porous sound absorbing material in the case where the interior fabric is attached with the purpose of improving the surface durability; A sound absorbing board for melamine resin, a sound absorbing board for melamine resin foam, a sound absorbing board for urethane foam, a sound absorbing board for polyester, a sound absorbing board for glass fiber). In the present invention, The above problems can be solved

The natural pulp sponge is a natural pulp sponge, which is called a cellulose sponge or a viscose sponge, and has a density of 0.5 to 0.9 kg / m 3 and has an open cell structure. The size of the open pore diameter of the surface varies depending on the manufacturing method Approximately 0.5 to 7 mm. It is made of excellent sound absorption structure and made of natural cellulose, and can be used as an environmentally sound sound absorbing product, but it is not suitable as a built-in sound deadening material due to lack of surface durability. However, this problem can be solved by the sound absorbing lamination of the present invention.

A synthetic resin sound absorbing mat suitable for the present invention is a lightweight three-dimensional network mat (ENKAMAT-EU-COLBOND) produced by mixing a carbon material with a synthetic resin (Poly-amide-6) and differentiating it with various fiber thicknesses (0.2 to 1 mm) And its thickness is made from each thickness (10 ~ 25mm) according to usage, density is 25 ~ 35kg / m3, and porosity is about 95%. It is excellent in durability due to the use of carbon material, has excellent shape stability, and has excellent expansion / contraction ratio and shape retention according to the shape of reticular structure. The size of the open pore is 3 ~ 10mm in diameter, and its shape shows a three-dimensional network structure to the surface, so the surface area is enlarged to 50 ~ 100%, and when the sound absorption paint is laminated, the sound absorption surface area is enlarged by 50 ~ 100% Maximizing the efficiency and diffusing the incident sound to provide a desirable architectural acoustic environment.

Conventional use of such a synthetic resin mat is generally used as a back filling material for preventing interlayer noise, a flooring material for gait reduction, a gardening auxiliary material, a substitute for a carpet and the like. Especially, in case of ENKAMAT, The present invention is applied to the purpose of preventing the erosion of plants and the vegetation mat of plants, the interlayer noise preventing material, the dew condensation preventing material, and the construction of the drainage layer for landscaping. However, The present invention provides a new laminated sound absorbing material that provides a more preferable sound absorbing and diffusing environment of incident sound in an architectural sound space.

Sound-absorbing board Sound-absorbing tiles are mainly made of rock wool and made of sound-absorbing ceiling plate sound-absorbing tiles with cement plaster adhesive. These products are widely used as internal ceiling sound absorbing materials. However, in the general ceiling inside the building, the air conditioning indoor unit and the air circulation diffuser are installed, and the contaminated air and the contaminated convection concentrated by the diffuser are exposed to the problem of the easy contamination of the soundproof ceiling plate or the sound absorption tile.

However, the coating method for the maintenance and concealment of the ceiling has been widely used in general water paint (aqueous emulsion paints such as acrylic emulsion resin or synthetic emulsion, calcium carbonate, talc, kaolin, pigment, thickener, defoaming agent, It has been generalized that the sound absorbing pores of the sound absorbing ceiling plate or the sound absorbing tile are blocked by the paint film and the sound absorbing function is decreased and the repeated coating of the water paint is thickened and the sound absorbing function is lost.

This is a waste of resources and an economic loss. This is not an appropriate maintenance method for protecting the sound-absorbing function of the sound-absorbing material. The present invention can improve the sound-absorbing function and sound absorption performance by laminating the sound-absorbing paint or the sound-absorbing putty as means for solving the above problems, Can be improved.

Below, examples of porous sound absorbing materials (porous sound absorbing materials) used in building sound absorbing spaces are shown as examples of reduction of sound absorbing performance due to maintenance painting and color changing coating using general paints.

[Table A]

In Table A, the sound absorption performance after two paintings using the general paint was drastically reduced, and in particular, it was reduced by about 50% in the 500 Hz range and gradually decreased more in the 1000 Hz range and 2000 Hz range.

In Table A, the sound absorption performance after one painting using the general paint began to decrease at the 700 to 800 Hz range, and the reduction rate was further increased at the 1000 Hz range and the 2000 Hz range.

The reduction of the sound absorption performance of this range (500Hz ~ 1000Hz ~ 2000Hz) causes a bigger problem in the noise-free space, and the space where the sound absorption of the high frequency range is important is the lobby, the cafe, Space, exhibition space, etc., the sound absorption of the high frequency sound source is more important than the control of the architectural sound required in the professional performance facility.

In Table A, the sound absorption performance after one painting using the general paint increased, in particular, the sound absorption performance was increased at a frequency of 125 Hz, the sound absorption performance was increased by 50% at a frequency of 250 Hz, , And the sound absorption performance began to decrease at 700 ~ 800 Hz range. This shows that the sound absorbing characteristics of the porous sound absorbing materials are affected by the exposed surface treatment (the physical properties and the shape structure of the exposed surface finishing method and the finishing material). Therefore, when a part of the excessive surface opening pores of the porous sound absorbing materials are blocked, 750 Hz to 500 Hz to 250 Hz to 125 Hz).

However, this shows a problem that the sound absorption performance is rapidly deteriorated from the middle frequency range to the high frequency range. Such a sound-absorbing pattern is not suitable for a sound-absorbing space of a building, and preferable sound-absorbing characteristics should exhibit a sound-absorbing performance uniformly over a low frequency range, a middle frequency range and a high frequency range.

Therefore, the principle of the laminated sound-absorbing structure of the present invention is to block a part of excess surface opening pores of porous sound-absorbing materials, to constitute a dense sound-absorbing laminate composed of finer open structure cells and to uniformly absorb sound over a low- Lt; RTI ID = 0.0 > sound-absorbing < / RTI >

The patent application No. 10-2007-0106309 discloses "a sound absorbing material having improved sound absorbing performance" in the domestic patent field, and it is a porous material which increases the low frequency and intermediate frequency sound absorbing performance of the porous sound absorbing material This paper presents an improved wedge porous sound absorbing material which improves the low frequency and intermediate frequency sound absorption performance by using wedge type porous sound absorbing material which is effective for medium to high frequency sound absorption in general. It is a shape suitable for special space focused on performance rather than consideration of design.

In Japanese Patent Application No. 10-2006-7000383, "Soft polyurethane foam and its manufacturing method" are introduced, and a manufacturing method of increasing the low frequency and medium frequency sound absorption of polyurethane foam porous sound absorbing material is introduced. This is a flexible polyurethane foam with a high density of 80 to 100 kg / m 3, which is different from a soft polyurethane sound absorbing board which is generally used for sound absorption (30 to 40 kg / m 3) and has an open pore. The polyurethane foam molding mold , The density of the foam is increased during the foam manufacturing process using a two-pack type high-pressure expanding machine to control the excessive air permeability of the foam (excessive opening pore control) and increase the density (80 to 100 kg / .

However, the use of such a high density and a large amount of urethane resin (two to three times as much as that of a polyurethane foam sound absorbing board and a urethane resin foam sponge used in general use) leads to an increase in production cost and an increase in the amount of urethane resin The use of flame retardant materials (fire protection standards for building use multi-use facilities construction standards, use of quasi-fire retardant materials for building interior use) should be increased and as the amount of flame retardant used increases, the rebound resilience of flexible polyurethane decreases, resulting in a decrease in low frequency sound absorption The increase in the weight of the built-in finishing agent has a problem of lowering the workability and increasing the load of the building.

However, in the present invention, since the sound absorbing paint or the sound absorbing putty laminate having a thickness of 0.5 to 5 mm on the exposed surface of the porous sound absorbing material is limited to the inner surface of the surface or the surface layer, the increase of the weight is minimized and the thickness (THK, 0.5 to 5 mm) And a lightweight three-dimensional sound absorbing material made of a porous and elastic material (a melamine foam sound absorbing material, a urethane foam sound absorbing material, a synthetic resin three-dimensional network roll mat felt Sheet is also provided with a lamination layer having a thickness of 0.5 to 5 mm so as to reduce the sound energy of the mid-low sound and to absorb sound. This allows the user to arbitrarily adjust the bending band of the target acoustic sound absorption frequency in the architectural acoustic space Sound absorption control structure.

Therefore, in order to gradually increase the low-frequency sound-absorbing function, a product having a high density among the sound-absorbing paint or the sound-absorbing putty is selected and the thickness of the lamination layer is gradually increased to lower the excessively open area ratio of the porous sound- And the sound absorption ratio of the laminated material is set to 0.1 mm to 0.22 NRC on the basis of a thickness of 3 mm in order to control the high frequency sound absorption performance more preferably

The material composition of the laminate composed of the sound absorbing paint or the sound absorbing putty used in the present invention is shown in the following application. The sound absorbing paint or the sound absorbing putty of the present invention is not a composition in which the closed coating film is formed, (open cell) structure. The terms "laminated material "," laminated material ", "to laminated material ", and the like denoted in the present specification are used as common terms representing one particular laminated material constituting the present invention, Quot; laminated material ", "laminated material "," laminated material ", and the like, The term "laminate" is used in one common sense to refer to "laminate" as used herein.

This is not to lower the sound absorption rate by being laminated on the surface of the porous sound absorbing material, but rather to increase the sound absorption rate, to provide a new paint on the faded or contaminated sound absorbing ceiling plate, sound absorbing wall surface, sound absorption tile, It is possible to improve the waste of resources by providing the effect of gradually increasing the sound absorption function as the number of recovery and thickness increases.

Sound absorbing paints or sound absorbing putties usable herein are the paints or putties shown below and the usable sound absorbing ratios are about 0.12-0.22 NRC (NRC based on reverberation room method sound absorption ratio) and suitably 0.15-0.20 NRC . The sound absorbing performance (NRC based on the reverberation room method sound absorption ratio) of the following sound absorbing paints or sound absorbing putties used in the present invention was approximately 0.15 to 0.20 NRC based on a thickness of 3 mm and was suitable for the present invention.

With respect to the density of the sound-absorbing paint or the sound-absorbing putty used in the present invention, the density of the sound-absorbing material is variously produced depending on the application and the compounding material and is produced in the range of about 200 to 620 kg / m 3. Also, the sound-absorbing putty is produced differently according to the respective functions, the method of use, the kind and the amount of the compounding materials, and is produced in the range of approximately 250 to 750 kg / m 3.

Therefore, various functions of the sound absorbing paint or the sound absorbing putty and products supplied with various densities are used as a lamination material to add various functions to the porous sound absorbing material. Particularly, the density is increased in proportion to the thickness laminated on the surface of the porous sound absorbing material And the density increase of the laminated material is controlled in the range of 200 to 750 kg / m < 3 >.

Such a structure can form a laminate having various densities and various thicknesses on the porous sound absorbing material in the architectural acoustic space or the sound absorbing space, thereby providing a desirable architectural acoustic space and a sound absorbing space capable of arbitrarily adjusting the sound absorption frequency band.

The sound-absorbing paint or the sound-absorbing putty is disclosed or filed by the present applicant (Application No. 10-2010-0006255, entitled " Multifunctional Sound Absorbing Putty Composition and Method of Manufacturing the Same), (Application No. 10-2004-0071486, A sound-absorbing paint or a sound-absorbing putty can be used, and a sound-absorbing paint or a sound-absorbing putty for sound absorption can be used. However, the present invention is not limited to the application (10-2004-0071486), and a sound absorbing paint or sound absorbing putty made by the method of the present applicant's application (Application No. 10-2010-0006255) were more suitable for the present application.

Therefore, the sound-absorbing paint or the sound-absorbing putty used in the detailed description and the embodiments of the present invention has been described as being manufactured by the inventions disclosed in the above application and the application, and the embodiment is shown.

Among the porous type absorbers, the characteristics of a wool board which is relatively inexpensive, safe and safe to fire and easy to work in woodworking, and which are generally used most frequently are described below.

A general construction method of a wool board to be installed in an architectural acoustic space or a sound absorbing space is provided with a plywood, an MDF, a gypsum board or the like as a back surface or a wood structure or a steel stud as a back structure. In such an installation method, the wood-binding adhesive or the rubber-based bonding agent is applied to a part of the back of the wooden board and fixed with a wooden pin. However, since most of the wool board is a woolen long fiber with a width of 1 ~ 3mm and a thickness of 0.1 ~ 3mm, it is weak and has a lot of pores. Therefore, it is attached using a large amount of Takanashi. There is a problem that part of the exposed surface of the wooly board is damaged.

In general, a wool board is collectively referred to as a wool board. For example, the roots of poplar trees are used as woodwood, and the logs are cut to a certain length (250 to 500 mm), and the roots of the roots of the centrifugal force There is a method of processing wood with a predetermined length (30 to 500 mm) while maintaining a constant thickness (0.1 to 3 mm) in the longitudinal direction. The use of tree roots is light in weight and sound absorption performance is comparatively good, but price is high due to limit of raw material supply. Therefore, in the industry, the production of woolen boards produced by processing wood is increasing.

The density of wood-wool wood-board is 280 ~ 330kg / ㎥, and the density of wood-wool wood board is 400 ~ 600kg / ㎥.

In the general production process, the above wood is precipitated in aqueous solution, aged, dehydrated, mixed with Portland cement, magnesium, adhesive, etc., and molded at high temperature and high pressure, cured and dried, and finished in accordance with the standard.

The general wool board has a slightly different quality and wooden shape according to the country of origin, the producer and the manufacturer (trade name: TECTUM TECTUM, Heracris Heraklith, Felicus Felicoustic, LCM) The problems are shown below.

The board has the general disadvantages of lumber materials, and it is a lumber material with a width of 1 ~ 3mm, a thickness of 0.1 ~ 3mm, a length of 30 ~ 500mm and most lumber length of 30 ~ 500mm. And has a woody long fiber shape that further expands the expansion ratio.

This is a woody structure with a small diameter and a long length, such as cooked noodles or bean curd, which has a shrinkage expansion rate that increases in proportion to the length of the neck, due to changes in moisture and temperature.

Therefore, the wool board is susceptible to moisture absorption and temperature change of wood fiber, and it exhibits a relatively large expansion / contraction rate in relation to the climatic change such as dry season, wet season, and seasonal temperature change, and repeated shrinkage and expansion according to the climate change, This weakens the state, gradually increasing the volume of some vulnerable surfaces, such as the corners of the wool board, reducing the adhesive strength of the cement binder and being easily damaged by external impacts. As a way to overcome this problem, there are also products that add the cement binder to the cut edge, edge, and corner of the wool board to alleviate the edge strength and swelling problem.

However, the woody board with the addition of the cement binder easily damages the cutting edge of the woodworking extension, and the workability in the woodworking on the site is disadvantageous, and the design surface of the exposed surface is defective. Are different from each other and it is a defect of interior design and the increase of the cement binder leads to an increase of the weight of the wool board.

Therefore, in order to overcome such a problem, there is a case in which a fabric cloth is attached to the surface of the wool board to conceal the surface, but it has problems such as an increase in cost and inconvenient work safety.

In terms of sound absorption characteristics, the open pores between the neck and the wool are excessively large and numerous, and the size of each pore formed is approximately 3 mm to 10 mm in diameter. These pores are 1 to 3 mm in width of the neck and 13 to 3 mm in thickness and 30 to 500 mm in length The three-dimensional structure is formed in a continuous interval, and the void ratio compared to the cross-linking density of the wood fiber is excessively enlarged to reduce the sound absorption performance. Therefore, when the structure is used in an acoustic space, a porous sound- And the double sound absorption structure used is also shown. Therefore, the sound absorption rate of the wood board is compared with the natural pulp sound absorbing material and the natural cotton sound absorbing material as the average sound absorbing ratio (NRC), which shows a very low sound absorption rate.

[Table 1]

This difference in sound absorption performance is attributable to the fine thickness of the fiber, the dense crosslinked structure of the fibers, the continuous structure of the open micropores, the innumerable quantity of open micropores, the fiber structure and the binder, which are excellent characteristics of the natural pulp sound- So that the elasticity of the sound absorbing material increases the sound absorption rate.

Therefore, the laminated material required in the present invention should be made of the excellent material characteristics and the sound absorbing structure described above, so that a sound absorbing paint or a sound absorbing putty is selected as a suitable material for the laminated material.

The structure of the sound absorbing paint or the sound absorbing putty used in the present invention is composed of the natural microfibers as described above, and is composed of an inorganic porous material of fine pores, a material which activates and increases open micro pores, a three-dimensional cross- , A multi-purpose sound absorbing paint or sound absorbing putty made of an environmentally-friendly functional material, and a sound absorbing ratio of 3 mm thickness is approximately 0.17 to 0.20 NRC, which is suitable for the lamination purpose of the present invention.

Suitably, the sound absorbing putty filed by the applicant of this application entitled " Application No. 10-2010-0006255, entitled " Multifunctional Sound Absorbing Putty Composition and Method of Making the Same " It is composed of vegetable sound-absorbing materials consisting of fine plant cells, cellulose, plant fibers, and functional sperm tissues of plants, and functional materials of fine open structure, inorganic porous sound-absorbing materials, bioactive materials of herbaceous plant woody plants, , A plant aroma component, a phytoncide, a plant pigment and the like, and is more suitable as a laminate material of the present invention because of its use and manufacturing method of further improving the three-dimensional sound absorption structure and sound absorption performance.

This is because the plant uses the beneficial immune substance, the antioxidant substance and the aroma spicy substance as the putty method, so that the environmental function of the porous sound absorbing material is improved and improved.

Also, this is a multifunctional putty having a dedicated diluting liquid in an absorbing putty, which is a functional putty which can be mixed with 2.5 to 15% by weight of the exclusive diluting liquid relative to 100% by weight of the absorbing putty. As a multifunctional absorptive putty which can control the viscosity of the absorptive putty, control the flowability, improve the workability, colorize various colors, activate the open pores, increase the sound absorption performance and increase the volume of the absorptive putty, Respectively.

Therefore, in the present invention, the sound absorbing paint or the sound absorbing putty laminate for improving the sound absorption efficiency of the wool board, improving the durability, and the function of the wool board is laminated in the thickness direction of 0.5 to 5 mm from the inner surface to the outer surface of the wool board To provide a wooly board.

In addition, the disadvantage of the design of the board design is that there is no design change for a long time, there are parts where the distribution of the wool on the surface is not uniform, the colors of the boards are different from each other, This is a disadvantage that can not be achieved.

This is because it is difficult to select the raw material as a raw material, it is difficult to uniformly lay it, the color of the wood is different according to the color of the wood, and the design defect which is caused by the uneven color of the raw material producing cement, magnesite, .

The surface of the wool board and the internal structure of the wool can be made of heavy materials such as wood, cement, magnesite and mineral materials constituting the board of the wool board to increase the density of the wood to increase the sound absorption performance and durability, And thus it has many problems in its use as an interior material due to an excessive increase in weight.

Another structural disadvantage of the general wool board is the horizontal distribution gap between the neck and the wool and the large gap of the open gap between approximately 3 mm and 10 mm, which acts as a design defect, The resistance is lowered and thus the sound absorption performance is deteriorated. In addition, such a structure provides a habitat and habitat environment for insects such as insects and cockroaches because of its large gap, and exhibits disadvantages of acting as a fusing space such as scattered dust particles.

The present invention improves the above problems and provides a new design functional woolen board.

As means for solving the above problem, a laminate is formed which improves the sound absorption performance and diversifies functions. This laminated structure provides a structure that partially closes, conceals and regulates excess open pores between the neck and the wool.

Such a structure improves the sound absorption performance, and more particularly, it is a sound absorption structure that is more effective in the middle and lower range, which increases the sound absorption function of middle low frequency (750 Hz ~ 500 Hz ~ 250 Hz ~ 125 Hz).

For example, in the case of a perforated plate sound absorbing material used as a sound absorbing material suitable for a medium to low frequency band (a porous sound absorbing material such as a glass fiber, a melamine sound absorbing board, and a polyester sound absorbing material on the back surface of an apertured plate having a perforation area of 3% to 30% + a perforated plate) The method of adjusting the translucency and the medium to low frequency sound absorption ratio is controlled by increasing or decreasing the aperture ratio of the apertured plate surface layer.

This is because the higher the aperture ratio of the apertured plate increases the high frequency sound absorption rate, while the smaller the aperture ratio of the apertured plate is, the higher the low frequency sound absorption rate decreases and the middle low frequency sound absorption rate increases.

In the present invention, such a sound absorption principle is utilized, and the excessive opening (open pore) of the porous sound absorbing materials is partially blocked or partially hidden thereby increasing the frictional resistance and viscous resistance efficiency of the medium low frequency sound incident on the surface, Thereby improving the sound absorption performance. The present invention also provides a structure for increasing the sound absorption rate of a porous sound absorbing material by a sound absorbing laminate having an additional thickness and formed by an outer surface.

In the present invention, a method for improving the problem of the porous sound absorbing material is provided, in which a wool board is installed in an indoor space as described above, and then a sound absorbing paint or a sound absorbing putty is laminated on the exposed surface of the wool board.

The construction method of this is to apply the sound absorbing paint or the sound absorbing putty to the exposed surface of the wool board by using a painting equipment, a putty tool, a trowel for trowel, and a press board, and then apply putty The surface of the wool board surface is laid out in the direction of the inner surface to the outer surface, the smoothness is maintained, and the laminating layer laid on the surface layer is pressed or scratched in the planar direction to form a horizontal surface, The present invention also provides a method of forming a three-dimensional pattern expressed in a process (the drying shrinkage of a laminate forms a three-dimensional pattern by forming a relief shape of a neck surface of a fixed surface).

This method in the present invention is a method that can be used both for forming the lamination inward from the surface of the porous sound absorbing material and for forming the lamination in the outward direction.

In the case of a three-dimensional pattern formation method in which the cross-section of the wood block and the wood color of the wood block are exposed on the surface of the porous sound-absorbing material of the wool board, the lamination may be performed on the surface layer of the wool board with a preceding process. In this method, the sound-absorbing paint or the sound-absorbing putty is laminated on the surface layer of the wool board to form a horizontal surface, and after drying, the wood protruding from the surface is sandwiched by 0.5 to 2.5 mm to reveal the cross- A three-dimensional pattern of wood color [Fig. 20] can be provided.

The above-mentioned three-dimensional pattern or relief carving method can be performed by various methods depending on the shape of the porous sound-absorbing material and the characteristics of the material.

In the above-described method of performing color painting only in the direction of the exposed surface of the woolen long fiber, since the produced shape of the woolen board is a cross-linked plate shape of a wood fiber made of a thickness of 0.1 to 3 mm and a length of 30 to 500 mm, Is made of wood fiber according to the shape and manufacturing method of wood fiber, which is exposed to the surface with a thickness of 0.1 to 3 mm, a width of 1 to 3 mm, and a length of 30 to 500 mm to form a plate-like sound-absorbing board.

Therefore, the protruded wood is painted using glossy or pearl material, It is possible to provide a color stereoscopic laminated sound absorbing material of new design in which harmonic color is expressed.

In the method of forming a relief piece on the surface of the laminated sound absorbing material, it is a method of selecting a porous sound absorbing material made of a material having a relatively fine shape of the surface of the porous sound absorbing material and being easy to use various engraving tools.

As the porous sound absorbing material capable of forming such a relief piece, a melamine sound absorbing board, a lightweight foam sound absorbing material, a polyester sound absorbing board, and a urethane resin foam sound absorbing board can be used, and preferably a melamine sound absorbing board and a lightweight foam sound absorbing material.

The melamine sound absorbing board is an open cell structure having a density of 9 to 11 kg / m < 3 > and a porosity of about 90 to 95%, which is a three-dimensional network structure formed by foaming a melamine resin finely. Some special products have a density of 6 to 8 kg / m 3 and a porosity of 95 to 98%, which can be used in the present invention. The melamine sound absorbing board made of such a structure is easy to be used for creative sculpting using various sculpting tools 40, 40a (Figs. 12 and 14). It is a lightweight material that can be easily handled and made of foamed melamine resin which is excellent in cutting and grinding processability, and has excellent elasticity, which is suitable for edge machining and shape machining. It is also a material with excellent fire stability.

The engraving tools available for the relief pieces include various types of electric sanders, various types of electric drills, electric power tools for engraving, electric grinders, abrasive tools, grinding tools, grinder dusters, woodworking abrasive tools, Tools such as torch lamps, compressors, air guns and the like can be used, and the attached tools include sanding-abrasive cutting parts attached to or used in the power tools, various types of choppers used in curved surfaces and mold release surfaces, Sponge sandpaper, various types of metal and plastic brushes, molds of various sizes, molds for shape design (horn, round, shaft type, etc.), disc wheel wheel cutter, (70) are available. In addition, film slide expander (Enlarger), image projector (Project), etc. can be used for precise and convenient work. The method of engraving using the above tools can be variously provided and the embodiments are shown below.

Melamine sound absorbing board having a thickness of 50 mm and a density of 9 kg / m 3 as a porous sound absorbing material was cut into a predetermined size and width, and vertical and horizontal lines were printed on the wall of the gypsum board, and a rubber elastic adhesive body was applied to the wall and the melamine sound- (30a) to the wall surface. Next, a crack preventing tape or a crack preventing cloth is attached to the butt portion of the melamine sound absorbing board, and a line putty (30c) for the purpose of preventing cracking and horizontal surface formation is completed by using the general putty or the sound absorbing putty. A film slide enlarger or a video projector (Project) 50 is held at a predetermined distance horizontally from the wall surface of the melamine sound absorbing board, (50a) and (50c) on the wall surface of the sound-absorbing board to fix the designed design or video image to the sound-absorbing wall surface (50c) by using the engraving tools, Sculpting can be done.

When projecting the design or design of the relief piece on the wall surface with the sound-absorbing board, the illumination of the workplace can be adjusted to make it clearer, and the size of the relief object can be arbitrarily adjusted. For example, it is possible to magnify the size of the ancient public to an archaeological size, compare the actual size of modern human beings, and carve a relief carving. This method can express the shape and size of objects more precisely and can easily express the symmetrical proportions of things in sculpture work. In addition, the projection angle of the magnifying unit or the image projector can be projected from diagonal to various angles, and the shape of the object can be reliably sculpted in an asymmetrical shape.

This method of carving carving can work as a general person rather than a professional writer. Therefore, it can reduce the work cost and can easily adjust the shape size of the carving design by horizontally moving back and forth with the slide projector or video projector symmetrical with the wall with melamine sound absorption board . Such a method can conveniently compose a natural landscape, a tree, a leaf and the like, and an animal shape. In addition, it has become possible to provide a laminated sound absorption method in which a variety of informed art works and writers' works are expressed as relief pieces.

As another embodiment, a method of engraving engraving using the mold for shape design can be provided. The melamine sound absorbing board having a thickness of 30 mm and a density of 9 kg / m < 3 > as a porous sound absorbing material was attached to the wall surface of the gypsum board in the same manner as described above. The butane portion of the melamine sound absorbing board was covered with a line putty To complete drying. Next, the mold 70 for shape design of the present invention, in which a leaf is shaped on a metal plate, is fixed to a melamine sound-absorbing board on a wall surface, a torch lamp spark is radiated (80a) on the boundary of a mold- shaped end line, and a melamine sound- . Then, after removing the mold for the shape design, the residue is cleaned with an air gun connected to the compressor, and the above-mentioned laminate is sprayed to a thickness of 0.5 to 5 mm (FIG. 13) To provide a porous melamine laminated sound absorbing material having a relief piece.

The use of the torch lamp used for the melamine sound-absorbing board relief engraving utilizes the physical properties and shape of the melamine resin netting material. The melamine sound-absorbing board does not propagate flame, has a low-temperature durability of -200 °, °, the temperature of the torch lamp flame is set to 250 ° or more, and when it is radiated (80a), the melamine resin network is scratched and the volume is reduced (the volume of the carbonized portion is reduced) and the carbonized film is formed. Such a carbonized film is easily removed by a brush (plastic brush, brush) or a sponge, and provides a method in which a three-dimensional shape is sculptured.

The mold for shape design 70 used in the present invention is a shape mold of the present invention, which is produced for easy compaction of a shape of an object. The shape of the object is closely adhered to a metal plate, It is a mold for shape design made by cutting and cutting according to the stamped shape. For example, a mold for shape design to shape leaves is a shape mold prepared by selecting leaves to be designed, attaching them to a metal plate having a thickness of 0.5 to 2.5 mm, and cutting and stamping the leaves according to the shape of leaves.
