Abstract

PURPOSE:To effectively utilize the resources and to produce natural stoneary(granite) tile by weight-mixing imitation stone consisting of coal ashes, etc., granulated to the prescribed grain size with a raw material of tile, molding and calcining the mixture. CONSTITUTION:Tile is produced by weight-mixing imitation stone (e.g. coal ashes are mixed with PVA and proper amount of water is added and the mixture is kneaded and the kneaded mixture is dried to form a rigid massive shape and then this is ground to obtain prescribed grain size) granulated to prescribed grain size with a raw material of tile (e.g. feldspar, 'GAIROME' clay and silica sand, etc., are blended at the prescribed ratio) consisting of plastic, nonplastic and fluxing materials and molding this mixture and calcining the molded body. By the above-mentioned method, grain size can be arbitrarily set in comparison with utilization of natural mica and also monotone of a spot pattern is eliminated and the produced tile can be approached to natural stone. Further sp. gr. of imitation stone for the raw material of tile is made low and therefore it is deposited in the vicinity of the surface layer of tile and thereby the amount of utilized imitation stone can be lowered. Furthermore since it can be uniformly mixed with the raw material, the tile product which bears comparison with strength and has fire resistance and weather resistance is produced at low cost.

Description

[Detailed Description of the Invention] [Object of the Invention] Industrial ■Kokuli Ridan The present invention manufactures tiles with a natural stone (granite) look using granulated coal ash, which is an industrial waste. The present invention also relates to a tile manufacturing method that makes effective use of resources.

Granite, a natural stone, is very widely used among stone materials, but because it is a natural stone, it is depleted of resources and relatively expensive, and it is also relatively easy to weather, so synthetic granite In recent years, there has been a demand for the production of

Conventionally, in the production of comb stone-like tiles, natural minerals such as mica and olivine sand are mixed into tile raw materials, molded, and fired in a reducing atmosphere.

However, since it is a natural mineral, the grain size of Gite is limited, and it is extremely difficult to obtain large grain size.
Therefore, various combinations cannot be made, and the texture of the spotted pattern becomes monotonous.

Also, since the specific gravity of Gite is heavier than that of the tile raw material,
It easily sinks into the interior and does not precipitate on the surface layer of the tile, and the stone is hidden by the raw materials, making it difficult to manufacture it into a comb-shaped stone pattern.

In addition, since it is a natural mineral, it is expensive, and it also has the disadvantage that sinkholes occur in the surface layer of the tile due to the influence of impurities in the raw material. By using coal ash, which is an industrial waste, we aim to reduce costs and make effective use of resources, and it is even closer to natural stone (granite), with improved fire resistance and weatherability, and a speckled pattern can be set arbitrarily. The purpose of the present invention is to provide a tile manufacturing method that can achieve the desired results.

[Structure of the invention]

i ゛ In view of the above, the present invention is a tile raw material made of plastic, non-plastic, solvent, etc., which is granulated to a predetermined particle size with an additive made of an organic substance, an inorganic substance, or an organic/inorganic mixture. The present invention aims to solve the above-mentioned drawbacks by providing a tile manufacturing method in which coal ash is blended by weight, molded, and fired.The present invention is made by agglomerating coal ash with additives and forming it into stone. By granulating and blending such Gite to a predetermined particle size into a tile raw material, shaping and firing, Gite is precipitated on the surface layer of the tile.

An embodiment of the present invention will be described below. MS-10, S made of plastic, non-plastic, and solvent materials
A predetermined amount (in this example, about 3 to 5 wt. Department)
It is blended, molded, and then fired (in this example, approximately 1
Natural stone (250 degrees, about 50 hours)
(Granite) tiles manufactured by UN.

Note that the blending ratio of Gite is not limited to the above ratio, and can be arbitrarily set as necessary.

Regarding the granulation of Gite, coal ash (raw material name, Daido), which is an industrial waste, is mixed with PVA (polyvinyl alcohol), an organic additive, in a predetermined ratio (in this example, Daido: P
Mix at a ratio of VA=2:1), add an appropriate amount of water and knead it, dry it to form a hard lump, and then pulverize to adjust to a predetermined particle size.

Another method for producing Gite is to form an aqueous solution of melamine resin or the like as a binder in an appropriate proportion, add this aqueous solution to coal ash, knead it with an appropriate amount of water, and dry it to form a hard material. It is formed into a lump, which is then pulverized and adjusted to a predetermined particle size.

Although there are many types of coal ash, the one used in this example has an SiO content of 43.6%).

Incidentally, the organic substance as a binder is not limited to the above-mentioned types, and any organic substance may be used as long as it has an effect as a binder.

〔Effect of the invention〕

In short, the present invention provides a weight blending method in which Gite stone is granulated to a predetermined particle size by adding an organic substance, an inorganic substance, or an organic/inorganic mixture to a tile raw material consisting of a plastic, non-blurable, solvent, etc. Because it is compacted, shaped, and fired, the particle size can be set arbitrarily compared to using natural mica, etc., so various combinations are possible, and the monotony of the speckled pattern is eliminated, making it a natural stone. It is possible to get even closer to .

Furthermore, since it has a lower specific gravity relative to the tile raw material than mica or olivine sand, it is precipitated near the surface layer of the tile, making it possible to reduce the amount of stone used.

Furthermore, since it can be mixed uniformly into the tile raw material,
It is possible to obtain a tile product that is comparable in terms of strength, fire resistance, and weatherability.

In addition, since it uses industrial waste, it can significantly reduce costs compared to conventional natural minerals such as mica and olivine sand, and it also allows for effective use of resources, resulting in better fuel efficiency and product color. The practical effect is extremely large because it can perform firing in a manner similar to that of the previous one.
