Abstract

The present invention relates to the technical field of unglazed ceramic processing and particularly provides a coating slurry material and a coating used for unglazed ceramic surfaces, an unglazed ceramic tile and preparation methods thereof. The provided coating slurry material used for the unglazed ceramic surfaces comprises epoxy acrylate resin, glycerin alkyd resin, 400-mesh quartz powder, 325-mesh alpha-alumina powder, hydroxyl-fluoro silicone oil, poly (butyl acrylate), chlorinated paraffin, emulsified silicone oil, dibutyl phthalate and propanol. The above coating slurry material is sprayed onto the surface of the unglazed ceramic tile by a spray gun; and drying is conducted to obtain the unglazed ceramic tile. The coating has good elongation, elastoplasticity, crack resistance, permeability resistance and weather resistance. When multilayer processing is conducted on the unglazed ceramic surfaces, the coating can also be used as a good transition layer to improve binding of other materials to unglazed ceramic green body.

Description

[0001] technology neighborhood [0002] The invention relates to the technical field of unglazed ceramic processing, in particular to a coating slurry for the surface of unglazed ceramics, a coating, unglazed ceramic tiles and a preparation method thereof. Background technique [0003] my country is a large ceramic production and export country, and the output of building and sanitary ceramics ranks first in the world for many years. With the gradual development of science and technology and the improvement of people's living standards, people's awareness of health and environmental protection is also increasing. For this reason, people have put forward higher requirements for the performance of traditional architectural sanitary ceramic products, which are mainly reflected in the environmental protection, anti-fouling, self-cleaning and easy-cleaning properties of ceramic products, as well as more health care functions. [0004] Most of the self-cleaning ceramic products cur...
