Abstract

The invention discloses a novel photo-curable epoxy acrylate resin coating for ceramic. The photo-curable epoxy acrylate resin coating is prepared from bisphenol A diglycidyl ether, dibutyl tin oxide, acrylic acid, titanium oxide, triethylamine, neopentyl glycol, a photoinitiator, cyclohexane diol, hydroquinone, terephthalic acid, a crosslinking agent, 1,6-hexanediol, diphenyl ketone, hexanedioic acid and dimethyl ethanolamine as raw materials. The glossiness of a product is 120%-140%, the hardness of the product is 4-6H; the surface drying time is 15-45 seconds, the hard drying time is 5-10 minutes; after the product is soaked in a 5% hydrochloric acid solution for 3-5 days, no bubbling and falling are generated and after the product is soaked in saturated calcium hydroxide for 6-8 days, no bubbling and wrinkling are generated; the product can resist the scraping for 2,000-3,000 times, the adhesion force is at Level 1-2 and the coating can be widely produced and continuously replaces existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a photocurable epoxy acrylic resin coating for ceramics. Background technique [0002] With the development of various industries in the national economy, the coating industry as a supporting tool has gradually developed from a very unobtrusive small industry to an indispensable important industry in various fields of the national economy. After several generations of hard work and pioneering spirit, my country has become the world's second largest producer and consumer of paint, and has entered the mainstream of the world's paint industry. And along with the popularization of humanization concept, and the formation of new harmonious society, it is very necessary to design a kind of photocurable epoxy acrylic resin coating for ceramics with good adhesion, high hardness, solvent resistance and good gloss. Contents of the invention [0003] Technical issues solved: [0004] Aiming at ...
