Problems solved by technology

Since ceramic products are mostly made into daily necessities, the surface hardness of ceramic products is very high, and ceramics need to have good wear resistance, so the glaze on the surface of ceramics needs to have high hardness and high wear resistance. However, the existing glaze The coating does not have high hardness and cannot improve the wear resistance of ceramic products

Abstract

The invention discloses a high-strength porcelain glaze and a preparation method thereof. The high-strength porcelain glaze comprises the following materials: 50-70 parts of feldspar, 8-12 parts of quartz, 4-6 parts of calcite, 6-8 parts of barium carbonate, 7-9 parts of calcined talc, 3-5 parts of kaolin, 3-5 parts of calcined kaolin, and 1-3 parts of zinc oxide. The beneficial effects are that the high-strength porcelain glaze has good glaze face smoothness, good glaze slurry performance, wide firing range, wide application range, high hardness, good wear resistance, and prolonged service life.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a high-strength porcelain glaze and a preparation method thereof. Background technique [0002] China is one of the first countries in the world to apply ceramics. The so-called ceramics include pottery and porcelain. The products made from ceramics mainly include daily-use pottery, art pottery, and architectural pottery. Ceramics are widely used in the fields of tableware, decoration, and science because of their hard texture, fineness, and high temperature resistance. [0003] The surface of ceramic products often needs to be coated with a layer of smooth glaze. The glaze can not only prevent water, but also prevent adhesion and have good cleaning performance. Since ceramic products are mostly made into daily necessities, the surface hardness of ceramic products is very high, and ceramics need to have good wear resistance, so the glaze on the surface of ceramics needs t...
