Abstract

The invention discloses a radiation curing epoxy resin powder coating used for ceramic. Raw materials comprise a phenolic epoxy resin, polyvinylidene fluoride, 3-allyl isocyanate, polymethyl methacrylate, methylacryloyl chloride, ethyl acrylate, a photoinitiator, 2-ethylhexylacrylate, acrylic acid, polyethylene terephthalate, a cross-linking agent, glycerol, butanedioic anhydride, titanium dioxide and benzimidazole. Glossiness of a product is 130-150%; hardness is 6-9H; a surface drying time is 1-3 min; a hard drying time is 5-15 min; the product has no blistering or shedding phenomena after being immersed for 5-7 d in a 5% hydrochloric acid solution and does not blister or wrinkle after being immersed for 10-14 d in a saturated calcium hydroxide solution, washing fastness of the product is 1,800-2,000 times; and the product can be widely produced and replace conventional materials continuously.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a radiation-cured epoxy resin coating for ceramics. 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...
