Problems solved by technology

It is imperative to improve the whiteness of the glaze, but in the existing glaze formulation system, it is difficult to increase the whiteness of the glaze to more than 80 degrees only by adding zirconium silicate to the glaze, so there is no ideal high-grade glaze on the market. Whiteness ceramic tile surface glaze, so the industry urgently needs to develop a glaze whose whiteness is better than the glaze effect of the existing product whiteness to meet the needs of design

Abstract

The invention discloses ceramic tile overglaze with high brightness. The ceramic tile overglaze comprises, by weight parts, 80-120 parts of overglaze powder, 10-28 parts of zirconium silicate, 0.25-0.35 part of sodium tripolyphosphate, 0.2-0.4 part of carboxymethyl cellulose and 35-50 parts of water. By adjusting overglaze raw material ingredients and proportions and particularly by optimizing the added amounts of titanite and zirconium silicate in the overglaze powder, the ceramic tile overglaze has high brightness and has good postprocessing property, and apparent mass problems such as pinholes, blistering and deformation after application of the ceramic tile overglaze are solved.

Description

technical field [0001] The invention relates to the field of ceramic tile glaze, in particular to a ceramic tile surface glaze with high whiteness and a preparation method thereof. Background technique [0002] At present, the texture of high-quality stone on the market is better than that of glazed tiles. One of the most important items is the whiteness of the background color. The whiteness of high-quality white stone can reach 75 to 85 degrees or even higher. The whiteness that the current ceramic tile production process in the building materials industry can achieve is only 64 to 67 degrees. Especially the marble-like ceramic tiles have higher and higher requirements for the whiteness of the glazed surface. In order for ceramic products to obtain a texture closer to stone, and even obtain an artistic expression effect beyond stone. It is imperative to improve the whiteness of the glaze, but in the existing glaze formulation system, it is difficult to increase the white...
