Press formed dry glaze for ceramic tile adobe and its prepn process

Abstract

The present invention discloses one kind of dry glaze for once forming ceramic tile adobe and its preparation process. The dry glaze consists of type-I dry glaze and type-II dry glaze. The type-I dry glaze has the similar composition and sintered surface effect to that of ceramic tile adobe; and the type-II dry glaze consists of mineral materials and has the components including Li2O / Na2O / K2O 1.0-30 weight portions, CaO 1.0-25 weight portions, MgO 0-15 weight portions, ZnO 0-50 weight portions, BaO 0.5-20 weight portions, SiO2 40-80 weight portions, Al2O3 1.5-20 weight portions, ZrO2 0-30 weight portions, TiO2 0-35 weight portions, B2O3 0-30 weight portions, PbO 0-50 weight portions, P2O50-25 weight portions, and ceramic color or coloring oxide or other coloring compound 0-40 weight portions. The dry glaze may be used to obtain ceramic tile products with different surface decoration effects, high wear resistance, anti-fouling performance and other advantages.

Description

technical field [0001] The present invention relates to the raw material of ceramic brick and its preparation method, more specifically relates to a kind of dry type glaze that is used in one-time press forming production of ceramic tile body glaze and its preparation method. Background technique [0002] At present, the production methods of ceramic tiles with natural stone effects mainly include: use pre-adjusted clay materials with various colors, adopt different secondary cloth methods according to the pattern requirements, and have rigidity imitating natural stone textures on the surface. In the concave-convex mold made of materials, after being formed by a press, dried and fired, the surface of the product has an effect similar to natural stone with uneven surface. The disadvantages of this production method are: 1. Because the product only uses clay as a material, the surface effect changes very little, and only the texture and effect of clay after firing can be obtai...

AI Technical Summary

Problems solved by technology

The disadvantages of this production method are: 1. Because the product only uses clay as a material, the surface effect changes very little, and only the texture and effect of clay after firing can be obtained, and it is impossible to obtain the dullness and luster of glaze products. Surface effects such as matte, glossy, transparent, milky white or kiln change, etc., if you want to obtain a bright surface, you can only use polishing technology; and anti-fouling properties, if the surface is polished, it is difficult to meet the requirements for anti-skid and anti-fouling properties

3. There are few changes in surface color and pattern effect. Since all colors are obtained by color mixing of clay materials, there are few color types. In addition to the limitation of fabric methods during production, only some fixed patterns can be produced, and the pattern changes are single.
