Description

PAPERED Floor Comprising Scoria Particulate

The present invention relates to a floor plate. More specifically, the present invention is characterized by the use of cluster powder as an alternative to calcium carbonate or silica used as a reinforcing filler in general PP, PE and PVC sheets, PP, PE and PVC with improved properties for far-infrared radiation, warmth and moisture resistance. It's about burial.

In general, far-infrared rays are light with a wavelength of 3 ~ 1,000㎛, especially light with a wavelength of 5 ~ 20㎛ has excellent heat penetrating effect and thermal effect as light energy. In addition, it has been known to exhibit a thermal effect in vivo because of its high penetration in tissues. In addition, far-infrared rays are transmitted by radiation, reach and absorb deep into the human body or material, and resonate and resonate with the inherent wavelength of the material to activate molecular motion of the material. In particular, most of the human body consists of water and proteins, and when the vibration wave band such as molecular movement of these substances is irradiated, the molecular movement is activated, metabolism is promoted, blood circulation is activated, and aged cells are activated to waste products. And it promotes the excretion of excess fat, and can maintain the health by inhibiting the production of lactic acid, free fatty acids, fatty acid esters, cholesterol, uric acid and phosphorus, salts that cause fatigue or aging.

In this way, it is applied to various treatment devices, decorative tools, storage containers, beddings as well as mats by using ocher, jade, ganban stone and germanium, which emit far infrared rays. There are jade beds, roof boards, and jade mats. However, beddings such as floor coverings and mats made using such far-infrared rays have various problems. For example, in the case of the ocher plate disclosed in Korean Patent No. 173971, even though the ocher plate is made of ocher emitting far-infrared rays, the degree of solidification of the ocher is not firm and separation may occur over time. In addition, in the case of natural loess, the odor hygroscopicity is good, but since its component is a constituent of the soil, it is easy to breed microorganisms, so that the absorbed odor particles accumulate as it is used for a long time. The smell contained in the ocher particles is rather released, resulting in a bad smell, as well as the development of fungi due to the growth of microorganisms. Even in the case of the bed or jade bed using the recently developed ganban stone, the raw material is processed to make mats with ganban stone or jade itself or manufactured by combining a plurality of processed ganban stones or jade. Not only does the ratio of far-infrared rays radiate decreases, but the surface is hard and the user feels uncomfortable and there is a risk of injury. In addition, in the case of mat manufactured using jade disclosed in the Republic of Korea Utility Model Registration No. 192111 or conventional jade cushion or jade pillow, the jade processed in the shape of a disk is attached to the adhesive surface of the nonwoven fabric and used directly or by sewing. It was used to. However, the jade cushion or jade mat manufactured by the manufacturing method as described above may be damaged by sewing or adhesive parts due to friction even in a state where it is not used for a long time. The vinyl may burst by introducing into it, which is not clean and has a problem in durability.

On the other hand, most floor coverings currently used in Korea are PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride) flooring materials, and since the 60s developed as a substitute for hanji floorboards, residential culture As the apartment culture gradually changes and the income level improves, various products that are differentiated and advanced from existing products are being developed. Especially, functional flooring materials that have excellent thermal insulation, moistureproof and far-infrared radiation are required.

Accordingly, the present invention is to provide a floor plate having a level of thermal insulation, moisture resistance, far-infrared radiation and the like substantially satisfactory to the conventional PP, PE or PVC sheet. This object of the present invention is achieved by partially or wholly replacing calcium carbonate or silica with scoria powder, which has been previously used as reinforcing filler in PP, PE or PVC floorboards.

In one aspect, the present invention is characterized in that the reinforcing filler comprises a single cluster powder, a mixture of cluster powder and calcium carbonate or silica, or a mixture of cluster powder, calcium carbonate and silica, so that PP having thermal insulation, moisture resistance and far-infrared radiation can be obtained. Provides PE, or PVC flooring.

In another aspect, the present invention provides a single cluster powder, a mixture of cluster powder and calcium carbonate or silica or cluster powder, calcium carbonate and the like as a reinforcing filler in a mixture of PP, PE or PVC resins, plasticizers, stabilizers, foaming agents, diluents and pigments. A mixture of silica is added to form a sol, and the formed sol is coated or molded on a conventional sheet substrate and then gelled to provide a method for producing a PP, PE or PVC sheet having thermal insulation, moisture resistance and far infrared radiation. .

One of the main components of the present invention is a cluster of volcanic products. Volcanic eruptions are called volcanic eruptions by volcanic eruptions, gas, lava, rock fragments, and volcanic ash. When magma erupts on the surface, most of the gas present in it is released into the air and becomes lava. The lava contains a small amount of gas after the runoff, and the remaining ones collect on the surface of the lava flow to form round holes called vesicles. Among the volcanic eruptions formed in this way, rock fragments with many pores, light to white and floating in water are called pumice, and black rock fragments are called scoria.

Clusters have been used specifically in many fields. For example, US Pat. No. 6,311,448 describes clusters that can be used to make lightweight precast concrete plates such as roof tiles, floor tiles, wall tiles or house siding. US Patent Publication No. 20010002412 describes clusters for decorative use and contained in double matrix polymer impregnated-porous aggregates. U.S. Patent No. 4,300,056 describes that clusters from ferrous and non-ferrous metal manufacturing processes can be used to produce barriers of radioactive material. US Pat. No. 4,267,222 describes a polyester resin building panel incorporating many densified clustered particles of 1/4 to 11/4 inches in diameter. U.S. Patent No. 4,262,055 describes a refractory material using clusters as a lightweight refractory material. In addition, Korean Patent Registration No. 1996-0007379 discloses a method of preparing glazes by mixing a certain amount of oak clay and silicon oxide with crushed clusters and then supplementing additives such as sugar, MnO ₂ , Fe ₂ O _3, etc. It is. Korean Patent Registration No. 1996-0001655 describes a method of preparing frit by adding borax, arsenic acid, chili salt and sugar to cluster powder to produce crystallized glass tile therefrom.

Clusters may differ slightly in physical and chemical properties, including constituents, component ratios, specific gravity, porosity, specific surface area, etc., depending on the region, but such differences are insignificant. It will be appreciated that there will be little difference in assigning functionality. In the present invention, clusters are widely distributed throughout Jeju Island, Korea. A cluster of volcanic rocks, volcanic sand, and other volcanic ashes is a cluster of volcanic rocks. About 75% of the components of the island are silicon oxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ), and iron oxide (Fe ₂ O). ₃ ), in addition, it consists of calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (K ₂ O), sodium oxide (Na ₂ O), titanium oxide (TiO ₂ ) and the like. Composition ratios of the clusters used in the present invention are shown in Table 1.

In the present invention, it is found that the pine mushroom is processed into a powder, and the functionality of the heat retaining, moisture-proofing and far-infrared radiation is considerably increased when using the powder having a particle size of 0.1 to 40 µm. In particular, the particle size of the preferred cluster powder is 0.5-20 탆. Such powders can be obtained by first pulverizing natural clusters with a coarse mill and sieving using a mesh suitable for the desired particle size wet ball milled.

Since the content of cluster powder used in the sheet of the present invention is generally within 50% by weight based on the resin powder of calcium carbonate or silica in the sheet of PP, PE or PVC, it is typically 10 to 10 based on the amount of PVC powder resin. 50% by weight, more preferably 15 to 40% by weight, most preferably 20 to 30% by weight. In addition, the cluster powder of the present invention may be used alone or as a reinforcing filler of a long plate as described above, or may be used by mixing with calcium carbonate or silica which has been conventionally used. In the case of using such a mixture, calcium carbonate or silica is preferably used less than cluster powder, and more preferably within 10% by weight based on the resin powder.

The cluster powders of the present invention may be coated or molded on conventional substrates of PP, PE or PVC floorboards, or alternatively incorporated into the substrates. In one embodiment, the sheet of the present invention is composed of a resin layer 1, a foamed resin layer 2, a glass fiber 3, and an upper limb 4, as shown in Figs. The foamed resin layer 2 is a layer for absorbing shock and providing comfort, and is coated with a glass fiber (3) coated with a sol formed by adding PVC resin, plasticizer, stabilizer, filler, foaming agent, diluent, pigment, etc. Or foamed sheets rolled with a calendar or T die. Attaching the upper limb 4 to the foamed resin layer 2 and the glass fiber 3 is referred to as a base material or semi-finished product. In such a semi-finished product, the cluster powder of the present invention may be mixed with a PP, PE or PVC resin, a plasticizer, a stabilizer, a foaming agent, a diluent, a pigment, and the like, which are commonly used in a sheet, and may be incorporated into a foamed resin layer or coated on the foamed resin layer 2. Or may be molded. In particular, PVC synthetic resin has excellent adhesiveness, water resistance, etc., and has good shock absorption, which is suitable for offsetting the hardness of the floor and maintaining the comfort and comfort that the floor covering should have. The thickness and width of the foamed resin layer containing such a PVC synthetic resin may be appropriately adjusted to suit the conditions for maintaining the pressure and strength of the upper component layers.

Among the constituent materials of the foamed resin layer 2 or the upper limb 4, the filler is used for various purposes in the flooring material. For example, to reduce costs, reduce heat generation, reduce shrinkage, reduce coefficient of thermal expansion, increase modulus, improve resistance to mechanical impact, improve thermal or electrical conductivity do. Common fillers include silica, silicates, clays, calcium carbonate, asbestos, mica and the like. Among them, asbestos has been avoided since it was found to be a carcinogen. Calcium carbonate is the most widely used because of its ease of use, wide particle size distribution, low wear and relatively low specific gravity. However, in the present invention, in addition to the advantages of calcium carbonate or silica in the filler described above, the filler has physical properties and economics such as far-infrared radiation, heat retention, and moisture resistance, so that some or all of the calcium carbonate used may be replaced. While maintaining or improving the properties of the existing jangpan can provide a jangpan with the functionality of far-infrared radiation, thermal insulation and moisture-proof.

The PP, PE or PVC sheet of the present invention is, in one embodiment, a single cluster powder, a mixture of cluster powder and calcium carbonate or silica or cluster powder, carbonic acid as a reinforcing filler in a mixture of resins, plasticizers, stabilizers, foaming agents, diluents and pigments. A mixture of calcium and silica can be added to form a sol, and the sol formed can be prepared by coating or molding on a common sheet substrate and then gelling. The temperature at the time of gelling is 140 to 160 degreeC.

In a preferred embodiment, the raw material formulation and processing procedure of the sheet containing the cluster powder according to the present invention is as follows:

Raw Material Mixing Procedure

① Put liquid raw material of plasticizer and diluent.

② Rotate the stirrer of the blender and stir at low speed.

③ Slowly add powder of resin and filler.

④ Add small amount of additives (stabilizer, foaming agent, pigment, etc.).

⑤ Completely scrape off the powder from the blender wall and the stirrer.

⑥ Continue stirring the stirrer at high speed (500rpm, 20 minutes).

⑦ Discharge after confirming the mixing condition, temperature and viscosity.

⑧ Deflate.

<Processing procedure>

① Pour the sol compounded on the bottom of the semi-finished product and cast it to a certain thickness.

② Put in a thermostat maintained at 200 ℃, take out after about 25 seconds. The result is gelling that attaches to the semifinished product.

Plasticizers, stabilizers, foaming agents, diluents, pigments, and the like used in combination with the cluster powder of the present invention are well known to those skilled in the art, and their types and amounts are not critical to the present invention and those skilled in the art can appropriately select and use them. Plasticizers generally have the property of improving mechanical and thermal impact resistance, being non-reactive and moving to the surface and can disappear over time. Typical plasticizers include, but are not limited to, DOP (dioctyl phthalate) and BBP (butyl benzyl phthalate), with amounts of about 30 to 40 weight percent based on resin powder. In addition, examples of the stabilizer include DTL (dibutyl tin laurate), generally 2 to 5% by weight based on the resin powder. Blowing agents include, but are not limited to, ADCA (azodicarbonamide) and typical amounts of use are 1-2 weight percent based on the resin powder. Diluents are used to improve the handleability (workability and processability) of the resin. Diluents are generally non-reactive and may remain in unreacted form in the product to evaporate or migrate to the surface during use. Thus, they are used in small amounts because they can lead to severe physical property degradation of the cured product, and it is usually preferred not to exceed about 3% by weight relative to the resin.

As a further aspect, the cluster powder of the present invention can be applied to various semi-finished products. For example, a typical PVC sheet is an intermediate substrate in a structure in which a surface layer is deposited on the upper surface of the intermediate substrate layer around the intermediate substrate layer having elasticity, and a moisture-proof layer that blocks moisture or foreign matter is deposited on the bottom of the intermediate substrate layer. In a PVC sheet made of a base layer by mixing a layer of gannetite powders together with various raw materials, by reducing the amount of gannetite powder and partially replacing the cluster powder, a sheet having increased far-infrared radiation is produced or by mixing the cluster powder in the moisture barrier layer. It is possible to produce a sheet having increased moisture resistance. The manufacturing method of such a jangpan may refer to Republic of Korea Publication No. 20-1999-0020598.

As another example, a resin mixture containing cluster powder is coated or molded on the lower surface of a vinyl sheet having a light weight, cushioning and smoothness by heat-bonding a nonwoven fabric to the back surface of the stop layer constituting the PVC sheet. To provide additional functionality. The manufacturing method of such jangpan may be referred to the Republic of Korea Publication No. 20-1999-036197 and 20-1995-018979.

The invention will be more specifically illustrated by the following examples. However, these examples are merely embodiments of the present invention and do not limit the scope of the present invention.

Examples 1-4

Natural clusters obtained from Jeju Island were pulverized, ball milled and sieved to a mesh 600 to obtain cluster powder of about 20 μm or less.

Gels were prepared according to the following procedure using the compositions described in Table 2 below. The plasticizer and the diluent were added to the blender and the stirrer was rotated at 120 rpm and stirred for 4 hours. The raw materials of the resin and the filler were slowly added to the stirred liquid, followed by the addition of additives (stabilizers, foaming agents and pigments). The powder adhering to the blender wall and stirrer was thoroughly scraped off, and then the stirrer was further stirred at 500 rpm for 20 minutes and degassed to obtain a gel.

The formed sol was poured on the bottom surface of the semi-finished product having the glass fiber laminated on the foamed resin and the upper paper attached to the glass fiber and cast to a constant thickness (about 1 mm). It was placed in a thermostat fixed at 200 ° C. for 25 seconds and gelled to obtain a PVC sheet with a resin powder-containing resin layer.

Comparative Example

As in the above example, the crushed and ball milled natural clusters were sieved through several meshes (100 to 10000) to obtain cluster powders of various particle sizes. These cluster powders were used to vary the content of cluster powders by particle size (from as little as 2% to as much as 80% by weight of resin) to produce various PVC floorboards according to the same procedure as described in Example 2. Obtained.

Control Example

Using the same composition and procedure as in Example 2 above and using calcium carbonate instead of only cluster powder, a PVC sheet was obtained as a control.

Laboratory Example 1

Far-infrared emissivity and radiation energy were measured according to the particle size change and the cluster content change in the resin layer containing the cluster powder for the cluster powder-containing sheet according to the present invention prepared in Examples and Comparative Examples. This measurement was measured relative to the black body using the FT-IR spectrometer, the measurement temperature was at 40 ℃.

As a result, the far-infrared emissivity appeared best in the particle size of the cluster powder in the range of 0.1-40 micrometers. Table 3 shows the results of measuring the far-infrared emissivity and the radiation energy according to the cluster content change in the resin layer containing the cluster powder having a particle size ranging from 5 to 20 μm.

<Table 3> Far-Infrared Emissivity and Radiation Energy According to Cluster Contents of Cluster Sheets

Pine Powder Content (wt%) Emissivity Radiation energy (W / m ² ) 0 0.873 350 10 0.887 358 30 0.894 360 50 0.901 363 70 0.905 365

From the measurement results described in the above table, it can be seen that the emissivity is considerably increased and far-infrared radiation is excellent when the content of cluster powder is 10 to 50% by weight based on the total resin amount. Although more than 50% by weight of pine mushroom increased the emissivity, the increase rate was significantly lower than the amount used. Considering the amount of pine powder and the change in physical properties of the sheet, the amount of pine powder is preferably 10 to 50% by weight.

Laboratory Example 2

The present invention using the ASTM D882 (extension), ASTM D1204 (heat shrinkage, 120 ℃ 15 minutes) and ASTM D882 (tensile strength, kg / mm ² ) method for the sheet produced in Example 2 and Comparative Example The physical properties of jangpan containing pine powder and jangpan containing calcium carbonate instead of cluster powder were compared. As a result, the plate of the present invention showed substantially the same physical properties as the plate containing calcium carbonate.

Laboratory Example 3

Moisture-proof properties were measured using ASTM F372 (g / m ³ · 24 hours, 38 ° C. and 90% RH) method for the plate samples prepared in the above Examples and Comparative Examples. The feldspar was found to be at least 1.5 times better than the feldspar prepared using only calcium carbonate as filler.
