BRIEF DESCRIPTION OF THE DRAWINGS FIG.

[0009] Graphite silica is a natural product produced naturally.
It is a substance having the composition shown in Table 1.

[0010]

[Table 1] Graphite silica is a substance that emits far-infrared rays at room temperature to 100 ° C. or lower as shown in FIG. FIG. 2 shows the spectral radiant energy of graphite silica, which approaches the black body radiation line (theoretical ideal curve, which is indicated by a broken line in FIG. 2) having a peak at 8.0 μm at 80 ° C. The curve of the ideal radiation characteristic is drawn. (Refer to the solid line and the triangle in FIG. 2.) As shown in FIG. 3, the product of the present invention stably shows a high emissivity of 0.88% up to a wavelength of 6 to 15 μm.

According to the present invention, a plate is manufactured using graphite silica having a far infrared radiation function as a composition base material.

Next, each compounding material will be described with reference to FIG. 1. FIG. 1 shows a case where rubber chips are compounded.

The graphite silica 1 is mechanically pulverized to a fine particle diameter of 1 mm to several μm in maximum diameter, and is 5 to 35% based on the weight of the product.
Add about%. The reason why the amount of the graphite silica 1 added varies depending on the application. The particle size of the graphite silica 1 does not have to be evenly determined for each application.

The rubber chips or wood fragments 2 are indefinite, but if they are short rods (for example, pellets),
The maximum length is 10 mm or less, and if it is a lump, the maximum diameter is 5 mm or less. The maximum diameter in the case of a short rod may be the same as or different from the diameter in the case of a lump.

The purpose of blending the rubber chips or wood fragments 2 is to exhibit various properties such as being hard to cool once heated, having sound insulation properties, having cushioning properties, and having a slip-preventing function due to the cushioning properties. At the same time, industrial waste (eg, waste tires, waste materials, and the like) can be easily used and contribute to recycling of industrial waste. For the purpose of recycling, crushed pieces of general industrial waste such as waste plastic materials and waste cement materials can be used in addition to the above-mentioned rubber chips and wood crushed pieces.

The rubber chips or wood fragments 2 are mixed in an amount of about 94.5 to 60% by weight with respect to the weight of the product. The reason for the wide range of the mixing amount is that there is a difference depending on the use.

As the binder 3, a synthetic resin containing isocyanate / polyol as a main component (for example, a one-component urethane resin containing unsaturated isocyanate / polyol as a main component, an unsaturated polyester resin, a methyl methacrylate resin, etc.) is added. The amount of addition is about 0.5 to 5% by weight based on the weight of the product. The reason why the amount of addition is wide is to adjust the surface area of rubber chips, wood fragments, graphite silica, etc., and the wettability and the density of the plate due to the wettability.

Further, the reason that there is a wide range of addition amounts of the above-mentioned respective compounds is that even if the application in the broad sense is the same, but the application in the narrow sense is different, it is necessary to satisfy the characteristics required for the application in the narrow sense. This is because it may occur. (For example, even if the use in a broad sense is a building material, different properties may be required for a floor material and a wall material in a narrow sense of use in some cases.) Thus, the amount of addition of the above-mentioned compound varies. The reason is that even if the applications in the narrow sense are the same, there are cases where it is necessary to satisfy the required performance required according to the place where the product is used. (For example, even if a floor material is used in a narrow sense, different characteristics may be required for housing and livestock used in a barn, respectively.) By the way, the floor material and the wall material are used in the narrow sense. In the case of the former, various properties such as anti-slip function, cushioning, heat insulation or heat insulation, and sound insulation are required for the former, whereas the latter is different from flooring with cushioning, heat insulation, and sound insulation. Characteristics may be required, and even if flooring is used in a narrow sense, various properties such as anti-slip function, cushioning, heat insulation or heat insulation, and sound insulation are required for residential use. For livestock, properties different from those for houses, such as anti-slip function, cushioning property, heat retention or heat insulation, and abrasion resistance, may be required.

Next, the outline of the production method and products will be described.

After determining the product characteristics according to the application, graphite silica 1, rubber chips or wood chips 2, and binder 3 are mixed in the above-mentioned mixing ratio, and the mixture is mixed using a well-known room temperature press, a hot press or a well-known heating roll. In the case of heating, the mixture is heated at a temperature in the range of 50 to 200 ° C., and the mixture of the respective compounding materials is allowed to stand at room temperature for 3 to 10 hours. In the case of heating, the mixture is solidified for 5 to 20 minutes. Products (determined in the range of 3 mm to 50 mm depending on the application, required characteristics, etc.).

The relationship between the use of the product and the thickness will be described.
Residential building materials (for example, floor materials and wall materials that emphasize sound insulation)
As a standard, a thickness of about 6 to 20 mm is appropriate as a standard, and as a livestock building material (for example, a floor material of a livestock barn),
A suitable size is about 12 to 20 mm in consideration of the weight of livestock, and a mat to be laid on a road surface such as a snow-covered road surface or a frozen road surface is suitably about 10 to 30 mm in consideration of the weight of a vehicle or the like.

Further, referring to the relationship between the use of the product and the weight of the product, if the building material for a house (the floor material, the wall material, etc.) is about 6 mm thick when converted to a 600 × 600 mm plate, the weight is reduced. Approximately 3000g, if the building material for livestock (the floor material),
The weight is about 8000 g, and in the case of the road surface mat, it is standard to use the same weight as the housing building material.

Referring to the use and size of the product, in the case of the house building material (the floor material and the wall material), 1800 × 90
0mm size or 900x900mm size,
In the case of the livestock building material (the floor material), 900 × 900 mm
~ 2000 × 1200mm size, in the case of the road surface mat, 300 × 300mm size, 450 × 450
mm size, 600 × 600mm ～ 1800 × 900mm
The size of the place is appropriate.

By the way, the use, thickness, size, etc. of the above-mentioned products are determined in various sizes and 6 to 6 in accordance with the demands of users.
It can be manufactured to a thickness and weight of about 30 mm.
