Description

technical field [0001] The application belongs to the field of coatings, in particular to a photocurable coating for ceramics. Background technique [0002] Ceramics is the general term for pottery and porcelain. Humans invented pottery as early as the Neolithic Age, about 8000 BC. Ceramic materials are mostly oxides, nitrides, borides and carbides. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have higher hardness, but poor plasticity. In addition to the use of tableware and decoration, it also plays an important role in the development of science and technology. The raw material of ceramics is extracted from diethylene glycol, a large amount of original resources on the earth. The nature of clay is tough, it can be molded when it meets water at room temperature, it can be carved when it is slightly dry, and it can be ground when it is completely dry; it can be made into pottery when it is fired to 700 degrees, and it can be ...
