Problems solved by technology

However, in the preparation process of the existing dry granule bricks, in order to ensure the stability of the brick surface structure and avoid the three-dimensional effect of the glaze layer reducing the dry granules, the dry granules are arranged on the surface of the glaze layer, but at the same time the dry granules are limited. Embedded effect, resulting in relatively single three-dimensional effect, there are disadvantages of weak three-dimensional sense of fired brick surface, not fine texture, low anti-fouling performance

Abstract

The invention provides a preparation process of a dry-particle tile with strong tile surface stereoscopic sensation. The preparation process comprises the following steps: (1) drying a tile blank to obtain a dried blank; (2) mixing high-temperature dry particles with ceramic glue to obtain dry-particle slurry; (3) coating the dry-particle slurry on the surface of the dried blank to form a dry-particle layer; (4) coating base glaze on the surface of the tile blank with the dry-particle layer to form a base glaze layer, wherein the thickness of the base glaze layer is smaller than the maximum particle diameter of the high-temperature dry particles; and (5) putting the tile blank coated with the base glaze into a kiln and firing to obtain the dry-particle tile. Through the preparation process of the dry-particle tile, the high-temperature dry particles are combined with the ceramic glue to directly coat the dry particles on the surface of the blank body; then through combination of the covering effect of the base glaze, the prepared dry-particle tile is better in tile surface stereoscopic effect, more stable in structure, more abundant, fine and smooth in texture and high in skidding resistance and fouling resistance.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a preparation process of a dry brick with a strong three-dimensional effect on the brick surface. Background technique [0002] In the existing ceramic tile preparation process, usually in order to make the surface of the ceramic tile have a certain three-dimensional decorative effect and a certain anti-skid effect, after the surface of the tile is glazed, dry particles are often used to lay the glaze on the ceramic tile. The surface is finally fired at high temperature to form a brick surface effect with a certain raised effect. However, in the preparation process of the existing dry granule bricks, in order to ensure the stability of the brick surface structure and avoid the three-dimensional effect of the glaze layer reducing the dry granules, the dry granules are arranged on the surface of the glaze layer, but at the same time the dry granules are limited. Embedded...
