Abstract

The invention discloses an unsaturated polyester photocureable coating for ceramics. The coating comprises the following raw materials: epoxy polyurethane, ethylene glycol, ethanol, 1,2-propylene glycol, water, maleic anhydride, a tinting pigment, phthalic anhydride, propylene glycol triacrylate, adipic acid, a cross-linking agent, pentaerythritol, hexanediol diacrylate, trimethylolpropane and trimethylolpropane triacrylate. Glossiness of the product is 130-150%, hardness is 0.9-1, softness is 1-3mm and adhesive force is on 1st grade; the coating is free from phenomenons of bubbling and peeling after being soaked in water for 5-15d, and free from bubbling and wrinkling after being soaked in saturated calcium hydroxide for 1-5d; the coating is acid-resistant within 24-48h and 200# gasoline-resistant within 24h; the coating can be widely produced and continuously replace existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an unsaturated polyester photocurable coating for ceramics. Background technique [0002] The ceramic industry is developing rapidly in our country, and the sales market is gradually booming. my country is a big country producing ceramics, and the demand for ceramics is also increasing. From the perspective of the domestic market situation, the situation in recent years is gratifying. The supply of famous, premium and high-quality new ceramic products is in short supply. High-grade ceramics and medium-to-high-end sanitary ceramics are very popular. With the popularization of the concept of humanization and the formation of a new harmonious society, it is very necessary to design a kind of unsaturated polyester photocurable coating for ceramics with good flexibility, high hardness, good gloss and high impact strength. Contents of the invention [0003] Technical issues solved: [00...
