Abstract

The invention relates to an ultraviolet curing paint for ceramics, which is prepared from polyurethane acrylate, titanium dioxide, trimethylolpropane triacrylate, lithopone, water, talcum powder, tinting pigment, light calcium carbonate, ethyl acrylate, barium sulfate, crosslinking agent, benzoin aether, dimethylpropane carboxylate, diphenyl ketone and trimethoxy silane. The glossiness of the product is 120-130%, the surface drying time is 20-60 seconds, and the solid drying time is 30-40 minutes. The paint does not have the phenomenon of blistering or shedding after being immersed in water for 40-60 days. The paint does not blister or wrinkle after being immersed in saturated calcium hydroxide. The product can resist the friction of a cotton ball soaked in 95% ethanol for 8-12 hours, and can be widely produced and continuously used instead of the existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an ultraviolet curing coating for ceramics. Background technique [0002] Ceramic coatings have excellent weather resistance and processability, and are resistant to dirt and damage. Conventional ceramic coatings are resistant to scratches, but they are prone to cracks if the painted parts are bent, and fluorine-containing resin coatings and organic coatings are easily damaged by sand, stones, dust, etc. Therefore, the advent of ceramic coatings has been favored by the ceramic industry and is penetrating into other industries, with a bright future. With the popularization of the concept of humanization and the formation of a new harmonious society, it is very necessary to design a UV-curable coating for ceramics with good gloss, fast drying, good chemical and water resistance. Contents of the invention [0003] Technical issues solved: [0004] Aiming at the above technical problem...
