Abstract

The invention discloses an ultraviolet curing acrylic ester composition paint used for ceramic. The ultraviolet curing acrylic ester composition paint includes following raw materials: urethane acrylate, magnesium oxide, polyester acrylate, zinc oxide, water, light calcium carbonate, a crosslinking agent, quartz powder, dibutyltin dilaurate, sodium hydroxide, a coupling agent, benzoin ethyl ether, epoxy acrylate, diphenyl ketone and trimethylolpropane triacrylate. The paint is 110%-130% in glossiness, is 5-8 H in hardness, is 25-35 s in a surface drying time and 20-30 min in actual drying time, is free of a blistering and dropping phenomenon after being soaked in water for 30-50 days, is free from blistering and wrinkling after being soaked in a saturated calcium hydroxide solution for 5-15 days, is good in anti-wear performance and can be widely produced and replace conventional materials.

Description

technical field [0001] The application belongs to the field of coatings, and in particular relates to an ultraviolet-curable acrylate composition 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 "s...
