Abstract

The invention discloses an epoxy acrylate coating for ceramic. The epoxy acrylate coating comprises the following raw materials: epoxy resin, zinc acetate, methacrylic acid, phthalic anhydride, acrylic acid, toluene, a photosensitizer, tin tetrachloride, hydroquinone, zinc oxide, an activator, titanium dioxide, N, N-dimethylbenzylamine, barite powder and styrene. The surface drying time of the product, namely the epoxy acrylate coating is 15-25 seconds, the hard drying time of the product is 5-10 minutes, the adhesion force is at Level 1-3 and the hardness is 4-6H; after the product is soaked in water for 10-20 days, no bubbling and falling phenomena are generated; the coating resists the scrubbing for 1500-2500 times and 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 epoxy acrylate coating for ceramics. Background technique [0002] Ceramic coating is a novel ceramic coating that can react organic matter and inorganic matter, thus combining the advantages of both. The hardness of the new generation of ceramic coatings can reach above 6H. High temperature resistance 400 degrees, non-stick effect, a variety of colors. And it can be made into acrylic ceramic paint. With the popularization of the concept of humanization and the formation of a new harmonious society, it is very necessary to design an epoxy acrylate coating for ceramics with fast light curing speed, strong adhesion, solvent resistance and wear resistance. Contents of the invention [0003] Technical issues solved: [0004] Aiming at the above technical problems, the present application provides an epoxy acrylate coating for ceramics, which solves the technical problems of the exi...
