Conventionally, it is an essential condition that tiles are made of porcelain with common sense that firing is required and energy is required. Defective waste such as ceramic products generated during the production process had to be disposed of as industrial waste.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and aims to effectively utilize industrial wastes, and does not require any post-processing. It is an object of the present invention to provide a method for producing a plastic block having a tile-like uneven pattern which has a high appearance, is lightweight, and is easy to construct.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the manufacturing method of the present invention, a minute suction hole is provided in a mold, and a mold having a tile-like irregular pattern is set in a mold provided with an air suction device. The micro suction holes are for completely absorbing the plastic film laid on the mold surface into the mold, and are provided so as to be evenly distributed on the mold inner surface. If the suction hole is too small, there is a risk of clogging, and if it is too large, the partial suction attraction force of the film becomes large. The minute suction hole is connected to the air suction device and sucks air substantially uniformly from the entire surface of the mold.

The mold having the tile-like uneven pattern is made of metal or synthetic resin, and for example, aluminum, polyurethane, synthetic rubber, rigid polystyrene foam and the like can be used. The formwork may be a general concrete formwork, such as wooden,
Both metal and synthetic resin can be used.

A plastic film is laid on the surface of the mold and air is sucked. The plastic film is used as a surface protection and release material, and may be any as long as it is uniformly and completely adhered to the inner surface of the mold by suction. The material can be vinyl chloride, polypropylene, polyethylene, or the like.

A tile formed on the surface of a plastic block is prepared by pouring a composition comprising fine hollow ceramic particles, ground ceramic waste particles, cement and water. The composition is poured and filled into a concave portion which becomes a tile-like pattern of a mold having a tile-like uneven pattern. When filling, it is not necessary to apply pressure from the surface. This is because if pressure is not applied, the surface becomes somewhat rough, and if pressure is applied, the tile becomes a dense tile, which can exhibit excellent texture.

[0011] By using a cement as a binder, a composition comprising fine ceramic hollow particles having a water pressure resistance of 600 kgf / cm ² and a melting point of 1500 ° C or more and ground ceramic waste particles is formed into a tile shape, so that the surface is formed from the ground ceramic waste particles. It has a natural stone tone and brick pattern. In addition, the ceramic fine hollow particles can reduce the weight, and the ceramic fine hollow particles reflect light and exhibit excellent gloss and light brightness on the tile surface. By mixing and combining various types of ground ceramic waste particles, the stone-like or brick-like pattern can be arbitrarily changed.

In the present invention, in addition to the above, various surfactants, wrinkle inhibitors, thickeners, anti-sagging agents, anti-settling agents, anti-freezing agents may be used as dispersants to improve the properties of the tiles as required. An agent may be added. Further, for the purpose of improving the performance of the tile, a plasticizer, a stabilizer for preventing deterioration due to heat and light, a fungicide for preventing the occurrence of mold, and the like may be added.

[0013] The lightweight unfired tile has a water pressure resistance of 600 kg.
Use ceramic fine hollow particles of f / cm ² or more.
The hydrostatic strength is synonymous with the compressive strength of the ceramic fine hollow particles. When the compressive strength of the ceramic fine hollow particles is measured, the particles are put into water and pressure is applied to the water, and the pressure applied to the water is transmitted to the ceramic fine hollow particles to measure the compressive strength. If the ceramic fine hollow particles have low water pressure resistance, most of them are broken at the time of kneading the raw materials and forming the tiles, so that it is impossible to form a stone-like or brick-like tile surface having light brightness.

The fine hollow ceramic particles used have a water pressure resistance of 600 kgf / cm ² or more and a bulk specific gravity of 0.3 to 0.5.
g / cm ³ and a melting point of 1500 ° C. or higher. Therefore, it is not broken at all under the kneading conditions in the tile manufacturing process, nor is it broken at all during molding. In addition, the hardness and impact strength of the tile surface can be increased, and the ceramic fine hollow particles are uniformly dispersed on the tile surface, and exhibit excellent gloss and light brightness. That is, the ceramic fine hollow particles have a small particle size and are transparent or translucent in appearance and reflect when irradiated with light, exhibit an extremely high gloss and luminance surface, and can express a stone-like or brick-like texture color. You can.

The fine hollow ceramic particles are from 20 to 350
The fine particles having a diameter of 20 μm to 75 μm, a medium diameter of 75 μm to 150 μm, and a coarse diameter of 150 μm to 350 μm are used by adjusting the particle size. The bulk specific gravity is heavy for fine particles and light for rough ones, so the range of bulk specific gravity is 0.3 to
0.5 g / cm ³ . The amount of the hollow ceramic fine particles is in the range of 3 to 25% by weight. If the content is less than 3% by weight, it cannot be said that the gloss and the light brightness of the stone-grain or brick tone are sufficient and 25
When the content is more than the weight%, the physical properties of the tile are reduced.

Conventional inorganic fine hollow foams include shirasu balloons, glass balloons, silica balloons and the like, but the water pressure resistance of shirasu balloons is only 80 kgf / cm ² , and glass balloons and silica balloons are 150 to ² g / cm ^2.
Since it is about 00 kgf / cm ² , the object of the present invention cannot be satisfied.

Since the present invention uses ceramic fine hollow particles having a water pressure resistance of not less than 600 kgf / cm ² , the fine hollow particles are not destroyed at all during the kneading step of the tile raw material and the tile molding. Therefore, there is no reduction in volume due to the destruction, and no change in the composition due to the destructed particles. Tile molded on a plastic block can achieve its intended purpose completely as designed.

The crushed ceramic waste particles used in the present invention are obtained by crushing defective products generated in the porcelain production process. Pottery here refers to earthenware, pottery, stoneware, porcelain, and concrete products include black clay tiles, bricks, earthen pipes, earthenware tiles, interior and exterior tiles, sanitary ware, etc.
Stoneware is cold-resistant clay tiles, terracotta, pavement bricks, interior and exterior tiles, floor tiles, pottery tubes, etc., porcelain is interior and exterior tiles,
There are floor tiles, mosaic tiles, sanitary ware, etc. These products are used by crushing defective products and waste.

The crushed ceramic waste particles are fine, medium, and coarse, and the fine particles have a particle diameter of 0.1 to 0.5 mm, a medium of 0.5 to 1.5 mm, and a coarse of 1.5 to 3 mm, respectively. Adjust to 4 mm before use. In addition to the crushed ceramic waste particles, silica powder, fly ash, silica fume, clay, talc, kaolin, slow-cooled blast furnace slag slag, siliceous dust, etc. may be added as necessary.

The color of the ground ceramic waste particles differs depending on the original ceramic product, and a unique texture can be obtained by blending them in various ways. For example, it is possible to express a completely new tile-like pattern, which has not existed conventionally, by adding an appropriate amount of the medium size of the white sanitary ware waste particles to the coarse and fine particles of the ground brick waste particles.

The cement used in the present invention is not particularly limited. For example, Portland cement such as ordinary Portland cement, early-strength Portland cement, ultra-high-strength Portland cement, moderate heat Portland cement, sulfate-resistant Portland cement, etc., and blast furnace cement , Silica cement, mixed cement such as fly ash cement, white Portland cement, cement-based solidifying material, and special cement such as alumina cement. Of these, ordinary Portland cement is preferably used in terms of price and quality.

By using a cement as a binder, a composition composed of fine hollow ceramic particles having a water pressure resistance of 600 kgf / cm ² or more and crushed ceramic waste particles is molded into a tile-like pattern, whereby the surface of the plastic block is improved. The gloss and light brightness of the tone and brick tone were able to be exhibited.

The shape and size of the tile-like pattern formed on the surface of the plastic block can be arbitrarily designed.
The dimensions are free and varied, and square, rectangular, triangular, round and other special shapes are possible. Any size and shape can be formed from small mosaic tiles to large tiles of 1 m or more.

A composition for forming a tile-like pattern is poured and filled in the concave portion of the mold, and then cement mortar is poured. A plastic block and a tile-like uneven pattern are laminated via a cement mortar. The cement mortar has a function as an adhesive, a backup substrate for the tile, and a function as a joint material for the tile.

The hard foamed plastic hollow block surface is placed on the cement mortar surface, the mold frame is rotated by 180 degrees so that the hard foamed plastic hollow block faces down, air suction from the minute suction holes is stopped, and pressure bonding is performed. I do. The rigid foamed plastic hollow block is made by extrusion molding or bead molding, and the material of the plastic may be any material that can be extruded or bead molded, and vinyl chloride, polystyrene, phenol, polyisocyanurate and the like can be used. Polystyrene is preferred. The size of the hard plastic hollow block may be the same as that of concrete, and because of its light weight, larger dimensions than the concrete block are possible.

Tile is adhered to the surface or the front and back surfaces of the hard foamed plastic hollow block via cement mortar, and then the surface protection and the plastic film as a release material are removed and cured. Through the above steps, a plastic block having a tile-like uneven pattern can be manufactured.

The construction of the plastic block having the tile-like uneven pattern according to the present invention is exactly the same as that of the concrete block. The plastic blocks are successively stacked on the upper part on which the basic concrete has been cast, and a reinforcing bar or an aluminum material is inserted into a hollow portion of the plastic block, and a cement mortar is cast into the hollow portion.

The crushed ceramic waste particles used were crushed particles of Sanshu roof tiles, and the particle size was adjusted to 10 parts by weight and 70 parts by weight. To this, 20 parts by weight of a medium size of ground white sanitary ware waste particles were added and blended.

On the tile composition, cement mortar is poured into a thickness of 7 mm, and a rigid foamed plastic hollow block is placed thereon. The mold is rotated by 180 ° so that the rigid foamed plastic hollow block is on the lower side and air is blown. The suction device was stopped and the form was removed from the rigid foamed plastic hollow block. A tile-like irregular pattern was stuck on the upper surface of the hard foamed plastic hollow block via cement mortar, and the coated vinyl chloride film was peeled off and cured at room temperature for 24 hours.

The method for producing a plastic having a tile-like uneven pattern according to the present invention does not require any post-processing and has a high appearance such as a stone-like or brick-like pattern with a deep tile-like unevenness and excellent mechanical strength. It does not require large-scale manufacturing equipment, and can be easily manufactured even by a skilled worker. Also, the manufactured plastic block having a tile-like uneven pattern was light in weight and could be easily applied.

The use of defective pulverized particles generated during the ceramic production process and the use of cement as a binder produce tiles having performance comparable to fired ceramic tiles despite being unfired. We were able to.

By changing the composition of the crushed ceramic waste particles, it was possible to arbitrarily express various stone-tones and brick tones of a natural stone style.

The ceramic wastes disposed of as industrial wastes can be effectively used, and the ceramics can be molded by non-firing, so that the energy saving effect can be made extremely high.

The ceramic fine hollow particles are uniformly arranged on the surface of the tile, and the ceramic fine hollow particles are transparent or translucent fine hollow, and can be reflected by light irradiation to exhibit extremely high gloss and light brightness. By further buffing, a more excellent texture could be developed.

Lightweight tiles are formed by using lightweight ceramic fine hollow particles, and a plastic block having high heat insulation and lightweight tiles can prevent a rise in temperature due to solar heat in summer, and can reduce the weight of the lightweight tiles. The surface is high in hardness and hard to be scratched, can express the same smoothness as natural stone, and is strong against acid, so it is not contaminated by acid rain.
