Fully-polished glazed ceramic tile and preparation method thereof

Abstract

The invention discloses a fully-polished glazed ceramic tile and a preparation method thereof. The fully-polished glazed ceramic tile comprises a green body layer, a ground glaze layer, a printed layer and a fully-polished glazed layer from bottom to top; the fully-polished glazed layer is prepared from the following raw materials in parts by mass: 5-20 parts of potassium feldspar, 30-60 parts ofalbite, 4-15 parts of calcite, 6-12 parts of kaolin, 0-6 parts of calcined zinc oxide, 2-10 parts of quartz, 2-8 parts of calcined soil, 2-10 parts of zirconium silicate, 0.1-0.3 part of methyl and 0.3-0.6 part of a tripolymer. The preparation method has the advantages that an all-raw-meal formula is adopted, so that the production cost is lowered; the problem of yellowing caused after combinationof light-colored or white fully-polished glaze and ground glaze is solved, so that the product grade is improved; the whiteness of the light-colored or white fully-polished glaze is improved, and thecompetitiveness of the light-colored or white fully-polished glaze in the market is improved. Furthermore, the preparation method also improves the wear-resistant level and corrosion resistance of the product.

Description

technical field [0001] The invention relates to the field of building ceramic production, in particular to a fully glazed ceramic tile and a preparation method thereof. Background technique [0002] At present, fully glazed ceramic tiles occupy a dominant position in the architectural ceramics market. The whiteness of light-colored, especially white full-glazed ceramic tiles is an important factor to measure the quality of ceramic tiles. According to production experience, the color of the full glazed bottom glaze will turn yellow when combined with the full glazed glaze. At present, the main way to improve the whiteness of light-colored ceramic tiles in the industry is to increase the glaze amount of the bottom glaze or increase the content of zirconium silicate in the bottom glaze. This method is not only costly, but also when the amount of glaze is large to a certain extent, many glaze defects will appear, and when the content of zirconium silicate in the bottom glaze i...
