Abstract

The invention discloses a colored gloss coating for ceramic. The colored gloss coating comprises the following raw materials in parts by weight: 100 parts of butyl acrylate, 10-30 parts of polypropylene glycol, 35-55 parts of olive oil, 15-25 parts of 2,4-benzophenone diisocyanate, 80-100 parts of water, 15-35 parts of hydroxyethyl acrylate, 5-15 parts of coloring pigment, 20-40 parts of N-vinyl pyrrolidone, 5-15 parts of potash soap, 40-50 parts of triisocyanate, 1-5 parts of cross-linking agent, 1-10 parts of benzoin diethyl ether, 10-20 parts of urea, 3-7 parts of benzophenone and 5-25 parts of clay. The gloss of the colored gloss coating is 100-120%, the hardness of the colored gloss coating is 5-7H, the surface drying time of the colored gloss coating is 30-40 seconds, the hard drying time is 20-30 minutes, no foaming or dropping phenomenon is generated after the colored gloss coating is soaked in water for 30-60 days, no bubble or shrinkage is generate after the colored gloss coating is soaked in saturated calcium hydroxide for 10-20 days, no color change or powdering phenomenon after the colored gloss coating is radiated for 100 hours in ultraviolet light, and the colored gloss coating can be widely produced to replace conventional materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a colored and glossy 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 obtained by quenching the earth's original large resource clay. 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 filled with wat...
