Abstract

A long-acting ceramic whitening glaze is prepared from raw materials in parts by weight as follows: 3-10 parts of strontium carbonate, 4-9 parts of cobalt acetate, 6-10 parts of polymethylsiloxane, 2-7 parts of zirconium silicate, 6-11 parts of tetraethoxysilane, 3-10 parts of metakaolin, 3-8 parts of polyvinyl alcohol, 2-6 parts of tertiary calcium phosphate, 3-11 parts of titanium dioxide, 3-9 parts of forsterite, 2-8 parts of quartz powder, 1.2-4 parts of zirconium silicate, 4-7 parts of zinc oxide, 6-8.5 parts of aluminum oxide, 1.2-3 parts of quartz, 1-3 parts of Sc2O3 and 4-7 parts of lithium borohydride. The long-acting ceramic whitening glaze has the benefits as follows: the brightness and the glossiness of the ceramic glaze can be improved very well, meanwhile, long action is realized, and the use cost is low.

Description

technical field [0001] The invention relates to a long-acting ceramic whitening glaze. Background technique [0002] At present, my country has tens of thousands of building ceramics and sanitary ceramics manufacturers, tens of thousands of production lines, and thousands of daily-use ceramics factories. The annual output of architectural ceramics is nearly 3 billion square meters, tens of millions of sanitary ceramics, and 100 million pieces of daily-use ceramics. In the existing ceramic firing process, the formula of ceramic glaze usually adopts the powder of natural minerals such as feldspar, quartz, limestone, calcium carbonate, lead as solvent or to increase the suspension of glaze. However, the existing glazes have limited whitening effect on ceramics, and cannot improve the brightness and gloss of ceramics well; moreover, the glazes are prone to cracking, resulting in low service life of ceramics and increasing the use cost.
