Transparent glaze and preparation method thereof

Abstract

The invention discloses transparent glaze and a preparation method thereof. The transparent glaze is prepared from the following ingredients in parts by weight: 2 to 6 parts of calcined zinc oxide, 5 to 7 parts of barium carbonate, 14 to 17 parts of soda feldspar, 6 to 8 parts of aluminium oxide, 1 to 3 parts of calcined soapstone, 17 to 19 parts of quartz, 19 to 22 parts of dolomite, 14 to 17 parts of calcined aluminum powder, 9 to 12 parts of wollastonite, 11 to 14 parts of nepheline powder, 0.1 to 0.4 part of sodium carboxymethyl cellulose, 0.3 to 0.6 part of sodium tripolyphosphate and 0.1 to 0.4 part of polyvinyl alcohol. After the ingredients are mixed according to the corresponding mixture ratio, the mixture is fed into ball mill equipment to be subjected to ball milling to obtain slurry; then, spray drying is performed to form powder materials; the powder materials are put into a cabin for obsolescence; the powder materials are pressed for forming a glaze blank; then, drying is performed; the glaze blank is calcined and is then crushed into powder materials; the powder materials are put for use. The glaze material is used for manufacturing ceramic tiles; the transparent effect of full polish product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a transparent glaze and a preparation method thereof. Background technique [0002] In recent years, the full-glaze market has gradually matured and occupied a large market share. With the sharp increase of full-glaze products, the market is gradually becoming saturated, and profits are correspondingly compressed. In the past few years when full-polished glazes have been popular in the market, due to the limitations of production technology, the glazes of dark-colored full-polished glazed products currently on the market have quality problems such as a small number of pinholes and slight dirt absorption, as well as acid and alkali resistance. Low hardness, local pockmarks and poor transparency lead to certain defects in this type of ceramic products, and are easy to be damaged when the use environment is poor.
