Description

Construction finish using ceramic composites and its manufacturing method {Structure Concrete Wall and the manufacturing method}

The present invention relates to a building finishing material, in particular, in addition to the far-infrared radiation effect, in addition to the negative ion generation, cooling and heating costs, toxic neutralization and deodorization, antimicrobial / anti-fungal, insect repellent, dust generation suppression and sound insulation effect, etc. It relates to a building finishing material and a method of manufacturing the same.

Modern people spend most of their day indoors. In this long-lived interior, more pollutants are gathered than we think, ranging from carbon dioxide that we breathe and harmful substances emitted from various building materials and building finishing materials.

Cement is the most commonly used material in the construction of buildings. However, when the wall or floor constructed with cement is exposed as it is, its durability is not only degraded, but the wall or floor is treated with a suitable material because it has a disadvantage of harming the human body due to dust or cement toxicity.

Of these surface treatments, the most common ones are oil-based or water-based paints. Paints include oil paints, enamels and water paints, but are usually oil paints. Oil paint is a colored opaque paint that is a good mixture of voile oil and pigment made from soybean oil, hemp seed oil, perilla oil, linseed oil, tung oil and fish oil, and is mainly used for surface treatment of walls or floors of buildings.

However, about 70% of the paints in circulation use volatile organic solvents as diluents and are treated as one of the causes of acid rain and are subject to VOC (Volatile Organic Compound) regulations to protect the global environment. .

In addition, paint and building finishing materials, which contain chemicals, are harmful to human health by releasing carcinogens such as formaldehyde, radon gas, and VOC (volatile organic compounds). In particular, radon, which is most emitted from mud, is recently released from gypsum board and concrete, which is widely used as a building finishing material, to harm a human body.

Thus, in order to solve this problem, researches that include components such as jade, charcoal, ocher, elvan, mica, germanium, etc. on the inner wall or bottom of the cement in the roots to emit far-infrared rays beneficial to the human body or to have an antibacterial effect. Are actively underway. One of the most studied of these studies is the method of mixing natural jade with paint.

However, in such a method, the beneficial components of jade are diluted with the paint, and the utilization effect of the jade components is insignificant. Therefore, in order to obtain a satisfactory effect, a large amount of jade is required, and in addition to the far-infrared radiation effect, anion generation effect, air conditioning cost reduction effect, toxic neutralization and deodorization effect, antibacterial / antifungal effect, insect repellent effect, dust generation suppression effect and There is a limit to the sound insulation effect.

Therefore, in addition to the far-infrared radiation effect, the need for building finishing materials to provide anion generation effect, cooling and heating cost reduction effect, toxic neutralization and deodorization effect, antibacterial / antifungal effect, insect repellent effect, dust generation suppression effect and sound insulation effect, etc. Is required.

The present invention has been proposed to solve this problem, in addition to the far-infrared radiation effect, can provide negative ion generation, cooling and heating costs, toxic neutralization and deodorization, antibacterial / anti-fungal, insect repellent, dust generation suppression and sound insulation effect, etc. The main purpose is to provide a building finishing material and a method of manufacturing the same using a ceramic composite.

According to an aspect of the present invention, there is provided a building finishing material comprising a ceramic applied to at least one of a wall or a floor of a building, comprising: hollow silica beads having a micro hollow portion formed in a body; It characterized in that it comprises a powder-liquid composite ceramic mixed with the hollow silica beads in a predetermined volume ratio.

It is preferable that the said hollow silica bead has a ceramic silicide as a main component, and a unit particle is 30-100 micrometers.

The powder-liquid composite ceramic includes a powder ceramic finely processed to a particle diameter of 375 to 400 mesh and a liquid ceramic, and the powder ceramic and liquid ceramic are mixed in a volume ratio of 1: 1.

In addition, the hollow silica beads are preferably mixed to maintain a volume ratio of 5: 1 with respect to the powder-liquid composite ceramics in which powder ceramics and liquid ceramics are mixed in a volume ratio of 1: 1.

The present invention also provides a method for manufacturing a building finish material comprising a ceramic applied to at least one of the wall or floor of the building, to provide a fine powder by grinding finely to maintain the average particle diameter of 375 ~ 400 mesh Steps; Silicate (Na ₂ SiO ₃ .xH ₂ O or K ₂ SiO ₃ ) is injected into the pressure tank at a ratio of 1: 10, followed by injecting 130 ° C direct steam to heat for 30 hours to prepare a liquid ceramic. Steps; Mixing the liquid ceramic and powder ceramic in a volume ratio of 1: 1 to prepare a powder-liquid composite ceramic; Disclosed is a method for manufacturing a building finishing material using a ceramic composite, comprising: mixing the powder-liquid composite ceramic with hollow silica beads consisting of hollow unit particles in a volume ratio of 5: 1.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The building finishing material 1 according to the present invention is a powder-liquid composite ceramic 40 obtained by blending a powder ceramic 20 pulverized in a particulate state with respect to a liquid ceramic 30 produced by liquefying a silicate at a predetermined ratio. , By mixing the hollow silica beads (10), and then applying it to the wall or floor of the building, in addition to the far-infrared radiation effect, anion generation effect, cooling and heating cost reduction effect, toxic neutralization and deodorization effect, antibacterial / antifungal effect, It will provide insect repellent effect, dust generation suppression effect and sound insulation effect.

In this case, the hollow silica beads 10 have a low thermal conductivity due to the shape of microscopic hollow spheres. Therefore, while reducing the overall size of the insulation equipment and the weight of the structure including the heat insulating material and the heat insulating material required to exhibit the normal heat insulating function, it is possible to exhibit a high heat insulating performance with a thinner thickness.

This thermal insulation function uses hollow silica beads bonded in a structure with very fine pores smaller than the average impact distance of air to lower thermal conductivity to the lowest level theoretically. This hollow silica bead 10 is representative of the following advantages.

① light weight; Since the interior is empty, the lightweight can be greatly improved by using a product having a very low bulk density.

② economic feasibility; As it is a light-weight filler, it is possible to obtain a high value-added product by reducing the manufacturing cost and improving the physical properties of the composite material due to the high bulking effect.

③ mixedness; Since the whole particle is spherical near the spherical shape, the usability with the raw materials is excellent and the mixing is uniform.

④ thermal insulation; Many pores inside the particles are closed, so the thermal conductivity is low, so the thermal insulation performance is excellent.

⑤ chemical stability; It is a product with high content of minerals, especially SiO2, and it is chemically stable due to few impurities.

The structure of this hollow silica bead 10 is shown in Figure 2, the overall physical properties and test evaluation results are shown in Table 1.

In other words, the unit particles 12 of the hollow silica beads 10 required by the present invention may have a circular body 12a and a microscopic hollow part 12b formed in the body 12a, as shown. ) These unit particles 12 have a distribution of 30 to 100 µm.

The hollow silica beads 10 having ceramic silicide as a main component have excellent heat insulation effect because fine hollow portions 12b are formed therein. In addition, it is not only organized to minimize responsiveness to radiant heat or microwave waves, but also can be mixed with all paints and coatings, and has little advantage of intermolecular friction because there is little molecular motion.

Test Items Physical Properties of Hollow Silica Beads (10) Exterior rectangle Particle Size (㎛) 50 to 110 Specific gravity (g / cm 3) 0.5 to 0.6 Melting Point (℃) More than 1500 pH 9.4 Chemical resistance (acid, alkali) clear

The hollow silica beads 10 may be directly applied to the floor or wall of a building, but in the present invention, the powder-liquid composite ceramic 40 is mixed with a predetermined volume ratio of 5: 1.

The powder-liquid composite ceramic 40 is pulverized in a particulate state with a liquid ceramic 30 produced by liquefying a silicate such as sodium silicate (Na ₂ SiO ₃ .xH ₂ O) or carbosilicate (K ₂ SiO ₃ ). It consists of a mixture of powdered ceramics (20).

Powder ceramic 20 is preferably finely ground unit particles to maintain 375 ~ 400 mesh. Since the powder ceramic 20 has a main component of silicon, it provides a unique ceramic effect. However, since the powder ceramic 20 is made of powder, it cannot be applied directly to the floor or wall of the building.

Therefore, in the present invention, the powder ceramic 20 is mixed with the liquid ceramic 30 using an additional ceramic having the same physical property as the liquid ceramic 30 in addition to the powder ceramic 20. The liquid ceramic 30 refers to a ceramic in a liquid state.

The liquid ceramic 30 may be manufactured by various liquefaction means, and in the present invention, a silicate such as sodium silicate (Na ₂ SiO ₃ .xH ₂ O) or potassium silicate (K ₂ SiO ₃ ) in a predetermined pressure tank. This was added in a ratio of 1:10 with water, and injected with direct steam of about 130 ° C. and heated for about 30 hours to prepare a ceramic powder in a liquid ceramic 30. The liquid ceramic 30 requires about 40 minutes to cure at room temperature.

In other words, the powder-liquid composite ceramic 40 is preferably used by mixing the particulate powder ceramic 20 and the liquefied liquid ceramic 30, but mixing them in a volume ratio of 1: 1. When the powder-liquid composite ceramic 40 is mixed with the hollow silica beads 10 in a volume ratio of 5: 1, the building finishing material 1 required by the present invention is provided.

In the building finish material 1 of the present invention, before the hollow silica beads 10 are cured, as shown in FIG. 2A, the unit particles 12 are disposed to be spaced apart from each other by volatile materials, water, and the like. However, when the hollow silica beads 10 are hardened together with the powder ceramic 20 and the liquid ceramic 30 added thereto, as shown in FIG. 2B, the unit particles 12 are in close contact with each other without being spaced apart. do. When there is no separation between the unit particles 12 as shown in FIG. 2B and the mutual contact, the continuous width H of the fine hollow portion 12b formed by the unit particles 12 becomes wider. As a result, the insulation effect is much better. In FIG. 2B, only a portion of the continuous width H of the fine hollow part 12b formed by the unit particles 12 is shown on the right side of the drawing.

On the other hand, in the building finishing material of the present invention, the mixing ratio with respect to the volume of the powder ceramic 20, the liquid ceramic 30 and the hollow silica beads 10 is 1: 1: 0.4. As a result, the mixing ratio of the volume of the mixed material of the powder and liquid ceramics 20 and 30 and the hollow silica beads 10 is 5: 1. At this time, since the powder ceramic 20, the liquid ceramic 30 and the hollow silica beads 10 are all ceramic materials having substantially the same physical properties, the mutual mixing force (cohesion force) is very high.

After the building finishing material 1 is formed with the above-described mixing ratio, it is applied to the wall or floor of the building. When the liquid ceramic 30 and the hollow silica beads 10 are cured after about 40 minutes have elapsed, volatiles or water between the unit particles 12 are evaporated, as shown in FIG. 2B. As the unit particles 12 come into contact with each other, the thermal insulation layer (continuous width H of the micro hollow portions 12b of FIG. 2B) by the micro hollow portions 12b is widened. Since the heat insulating layer forms a heat radiation shielding film, the building finishing material 1 used in the building can be kept cool in summer and warm in winter, thereby significantly reducing cooling / heating costs.

In addition, as shown in FIG. 2B, when each unit particle 12 of the hollow silica bead 10 is continuously bonded, a ceramic coating film is formed to provide sound insulation by reflecting sound waves as well as a heat insulating effect. It becomes possible.

On the other hand, since the building finishing material 1 according to the present invention is formed of a ceramic material having the same physical properties as described above, it is possible to further provide the following additional effects in addition to the above-described heat insulation and sound insulation.

In order to confirm the improved effect of the present invention, the building finishing material (1) according to the present invention was applied to the thermal insulation test evaluation according to Table 2, which is a quality standard prescribed in KSM 5310 <synthetic resin emulsion paint (for external use)>.

According to Table 3 and Table 4, the building finishing material (1) of the present invention has a performance that exceeds the quality standards prescribed in all test items without any difference between the general paint and the physical properties in the test items of non-volatile content, specific gravity, lead and wash resistance. It was confirmed that it was shown.

On the other hand, in addition to the above test, after constructing the building finishing material (1) of the present invention as interior and exterior materials, a test for the change in physical properties according to the long-term temperature change, that is, the temperature change resistance performance performed to examine the durability against long-term temperature changes Was performed and the results are shown in Table 5.

After repeated tests of the general paint and the building finishing material (1) according to the present invention under the above cycle conditions, there are no wrinkles, cracks, swelling, peeling, color change, gloss change and other harmful deformation in the coating of the two kinds of paints. It wasn't. As a result, it was confirmed that the building finishing material 1 according to the present invention sufficiently secures long-term stability against changes in outdoor air after construction.

These test results show that the effect of increasing the durability of the structure by improving the thermal performance and reducing the effect of direct temperature change of the building due to solar radiation and the effect of infiltration through the building envelope is very good. To disprove that.

On the other hand, using an asbestos cement plate (heat conductivity: 1.052 kcal / mhr ℃), which is relatively easy to transfer heat, the water-based paint and the building finishing material (1) according to the present invention in the space of 50 × 50 × 50 cm inside and outside the building The amount of change in temperature was measured in a chamber in which a certain amount of coating was applied and the air condition and temperature could be set.

Experiments at outside conditions were measured between 13:00 and 14:00, where solar radiation and temperature rise were the highest during the day, and experiments with temperature setting were made while changing from 40 ° C to 100 ° C.

The thermal insulation evaluation results for the water-based paint and the building finishing material (1) according to the present invention are as shown in Tables 6 and 7. The building finishing material (1) according to the present invention was found to have better thermal insulation than general water-based paint.

As shown in Table 6 and Table 7, since the internal temperature change when the building finishing material (1) according to the present invention is coated does not change sensitively to the change in the ambient temperature (this is referred to as "time retardation") You can see that the performance is greatly improved.

In general, the surface temperature of a building with rooftop greening in summer is about 20 ° C lower than the rooftop surface temperature of an existing building. According to the announcement, recording about 10% of domestic rooftops will save more than $ 36 million out of the total $ 8.13 billion in total energy consumption in 1997.

Based on these presentations, the results of this insulation performance test are 50 × 50 × 50cm, but the heat loss through the outer wall is 49% and the window has a significant effect on the heating and cooling loads of general buildings. Considering that the heat loss through 40% and the acupuncture affects the heating and cooling load to 8%, when the building finishing material (1) according to the present invention is installed on the roof or the outer wall of the actual building, the direct effect of the solar radiation It can be seen that the ripple effect on the heat efficiency in terms of heat transfer is excellent due to the improvement of the airtight performance of the building envelope, such as the reduction and the effect of infiltration through the building envelope.

On the other hand, based on the above test and the result, the building finishing material 1 according to the present invention can further provide the following effects.

First, the far-infrared radiation intensity is not only strong and high, but also has a lot of far-infrared emission at room temperature, penetrating deep into the skin of every part of the human body, activating the biological rhythm such as waste excretion, blood movement promotion and metabolism promotion.

Far-infrared emissivity and radiation energy test results show that the far-infrared emissivity reaches 91.5%, and the radiant energy from it is 3.68 × 10 ² W / m ² · μm.

Second, in the building finishing material 1 according to the present invention a large amount of negative ions are generated. Typically, the atomic element of negatively charged air, which is refreshed to the human body in forests, waterfalls, and hot springs, is an anion. When a valence electron is lost, a cation is obtained, and an electron is an anion.

Drinking these negative ions promotes cell metabolism and promotes vitality. It also clears blood and has the effects of nerve stabilization, fatigue recovery and appetite. The distribution of negative ions per 1cc of air in forests, hot springs, waterfalls, and coastal areas is estimated to be 800 ~ 2000, based on pleasant natural conditions.

The effects of negative ions are known so far to purify the blood, to activate the cells, to increase the resistance, to regulate the autonomic nervous system, to remove harmful substances in the body generated by electromagnetic waves, to activate the cells, to remove dust and bacteria It has been found to have a function of controlling humidity and removing odor.

However, as a result of constructing the building finishing material 1 according to the present invention on the wall of the building and conducting an anion measurement test, it can be seen that anion (ION / cc) of 1,230 is emitted and a large amount of anions are released.

Third, as described above, the microporous circular hollow silica beads 10 are additives made of granules having a space of fine vacuum therein with ceramic silicide as a main component. By adding, the cooling / heating cost can be significantly reduced.

Fourth, the building finishing material (1) according to the present invention penetrates into the cement pores to neutralize the toxicity and suppress the generation of dust (fine cement powder) to make the room a pleasant and warm health space, providing a neutralizing and deodorizing effect Done.

Fifth, the fine unit particles (glass reflector sphere, Reflectosphere) forming the hollow silica beads 10 is made of sodium borosilicate to exhibit a natural sterilization effect. Boron is commonly known as a natural disinfectant and insecticide. For this reason, the building finishing material (1) according to the present invention will be able to provide an antibacterial / antifungal effect.

Sixth, it can be seen that the space of the building constructed through the building finishing material according to the present invention does not give a gap to generate bacteria and mold, and also has an excellent insect repellent effect, such as no ticks.

Seventh, the building finishing material (1) according to the present invention by filling the pores of the cement without gaps to make the whole wall surface agglomerate reliably prevents the generation of cement dust provides an effect of suppressing dust generation.

Eighth, as shown in Figure 2, the ceramic particles of the micro-hollow structure of the hollow silica beads 10 are continuously bonded to form a ceramic coating film, thereby reflecting sound waves to maximize the sound insulation effect.

As such, the building finishing material (1) of the present invention has the above-described effect, by installing it on the floor or wall of the building, in addition to the far-infrared radiation effect, anion generating effect, cooling and heating cost saving effect, toxic neutralization and deodorizing effect, antibacterial It can provide antifungal effect, insect repellent effect, dust generation suppression effect and sound insulation effect.

In the above-described embodiment, the building finish material 1 is formed by mixing the powder ceramic 20, the liquid ceramic 30, and the hollow silica beads 10 with a volume ratio of 1: 1: 0.4. However, if necessary, the building finishing material 1 is provided with a powder ceramic 20, a liquid ceramic 30, and hollow silica beads 10, in order to give a higher adhesion to at least one side of the wall or floor of the building. The predetermined adhesive can also be mixed further.
