Antifouling glaze

Abstract

The invention provides an antifouling glaze material. The glaze material is prepared from the following raw materials: polymethylsilane, nano zinc oxide, sodium hexametaphosphate, wollastonite, pyrophyllite, barium oxide and a stabilizer. Nano-zinc oxide in the raw materials of the antifouling glaze can improve the glossiness, whiteness and glaze microhardness of the glaze surface of a ceramic finished product, and can reduce the initial melting temperature of the glaze; sodium hexametaphosphate is a polyphosphoric acid weak acid sodium salt with a cyclic molecular structure. A nano zinc oxidedispersion system is stabilized by an electrostatic stabilization mechanism; sodium hexametaphosphate forms a molecular layer protective film on the surface of zinc oxide; the surface energy of zincoxide particles is reduced; the coating effect is achieved to a certain degree; therefore, agglomeration among particles can be effectively prevented; the nano zinc oxide is stably and uniformly dispersed in the glaze; the polymethylsilane has very good oxidation resistance; pyrophyllite forms a compact mineral protection layer on the surface of the glaze; by adding wollastonite, the wear resistance of the product can be improved, the surface roughness is reduced, the accumulation space of pollutants is lost, the pollution resistance of the ceramic product is effectively improved, and the wollastonite can enable the hardness of a fired glaze layer to be higher and the glaze layer to be more wear-resistant, so that the glaze disclosed by the invention not only has a very good antifouling function, but also has good wear resistance.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to an antifouling glaze. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. In the past, people called ceramics made of clay and fired at high temperature in special kilns. Ceramics is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. Its main raw material is silicate minerals (such as clay, quartz, etc.) taken from nature, so it belongs to the category of "silicate industry" together ...
