Abstract

PURPOSE: A method is provided to manufacture an artificial stone plate like a granite plate by making shining mica and a black spot when manufacturing the artificial stone. CONSTITUTION: The method has: a material mixing process that kneads by mixing cement, sand and volcanic rocks with water; a molding process that presses by filling the kneaded material into a natural stone shaped mold; and a calcining process that softens by heating the molded material in a high temperature. Here in, the surface of the mold is sprayed with an adhesive aqueous solution, and mica and a black pigment are attached to the aqueous solution before filling the kneaded material into the mold. The kneaded material is filled after spraying the surface layer liquid mixed with pigment, cement and water.

Description

Manufacturing method of artificial granite plate and its artificial granite plate {A MANUFACTURING PROCESS AND PRODUCT OF ARTIFICIAL GRANITE PLATE}

The present invention relates to an artificial stone plate in which the texture of natural stone appears, and more particularly, to a method of manufacturing an artificial granite plate in which a texture such as granite appears and an artificial stone plate thereof.

In general, natural stone has been widely used outside or inside the building due to intimacy with humans.

However, these natural stones must be processed in a certain form to be used as interior and exterior materials of buildings, but it is difficult to obtain raw materials due to depletion of natural stones as well as causing a lot of time and manpower to be consumed. It was a situation.

In recent years, in view of such a situation, the artificial stone plate that appears as a natural stone texture with cement, sand, and volcanic stone as the main raw material is widely developed, the brief description of the conventional artificial stone plate manufacturing method as follows.

Conventionally, in order to manufacture an artificial stone plate, a material kneading process of mixing cement, sand, volcanic stone with water and kneading, a molding process of putting the kneaded material in the process into a mold formed like the surface of natural stone, and in the process It is to sequentially perform the firing process of curing the mold filled with the kneaded material at a high temperature for a certain time.

The conventional method of manufacturing artificial stone plate can be produced in the same form as natural stone, but can only represent the shape of natural stone in a simple form, it was not possible to produce a delicate artificial stone, such as granite.

In other words, the natural granite is used for the decoration of exterior wall boards in buildings, but it is difficult to obtain and process the raw materials, and it is difficult to process and construct it. It is the situation that is widely used as an article.

On the other hand, natural granite is not only exposed to the shiny mica on its outer surface, but also has a large amount of black spots. As a result of the conventional method of manufacturing artificial stone, mica and black spots such as natural granite could not be expressed. Therefore, it could not manufacture an artificial stone slab that satisfies the natural beauty.

The present invention has been researched and developed in order to solve the above problems, there is a technical problem to enable the manufacture of artificial stone plate, such as granite, so that shiny mica and black spots appear when manufacturing artificial stone.

1 is a front view of the artificial granite plate completed by the present invention.

The present invention is a material mixing step of kneading the cement, sand, volcanic stone and the like by mixing with water to manufacture the artificial stone plate, and a molding step of filling and pressing the material kneaded in the material mixing step in the mold in the form of natural stone; In a well-known method of sequentially performing a firing process of heating a material formed in the above step at a high temperature to harden, prior to filling the kneaded material into the mold, an adhesive aqueous solution is applied to the mold surface and mica and black The pigment is sprayed to adhere to the adhesive aqueous solution, and the dough material is filled after applying the surface layer liquid mixed with the pigment, cement and water.

Hereinafter, the present invention will be described in detail by way of examples.

Material mixing process

As a weight ratio, after mixing calcium chloride, hardening | curing agent, a pigment, etc. with 28-32% of cement, 35-39% of royal dust, and 26-30% of volcanic stone particles, water is added to the mixed material and stirred, and the dough material is prepared.

Molding process

Prepare a mold in which the bottom surface is formed in the form of natural stone.

An adhesive aqueous solution obtained by mixing a water-soluble adhesive liquid and water in a weight ratio of about 1: 8 to 15 is applied to the molding surface of the mold.

In the state that the adhesive solution is applied, the mica flakes and the appropriate amount of black pigments are evenly spread on the surface of the adhesive solution, and the amount of mica fragments and black pigments is applied to the amount of mica and spots attached to the natural granite surface. Adjust in consideration.

In addition, the surface treatment liquid obtained by mixing 20% granite pigment, 10% cement and 70% water in a weight ratio is laminated and coated on the mica-coated adhesive aqueous solution.

Subsequently, by molding and pressurizing the dough material prepared in the material mixing step into the mold, molding such as the mold bottom surface is performed.

Firing process

In the molding process, the mold is pressurized and filled with a material in a hot air chamber and dried at a temperature of 8 ° C. for 8 to 13 hours.

Finishing process

The product is completed by demolding the artificial stone plate from the mold after drying in the firing process.

The artificial stone plate manufactured as described above is formed in the form of natural granite like the bottom surface of the mold, and the shiny mica is attached to the surface, as well as the color and the black color of the granite by black pigment and surface treatment liquid. As the points appear in a distributed state, they generally look like natural granite.

Therefore, the present invention can manufacture artificial stone slab exhibiting the same texture as granite, it is advantageous to manufacture and supply low-cost artificial stone slab that can be used as interior and exterior plates of buildings without destroying natural granite It is an invention.
