Description

technical field [0001] The application belongs to the field of coatings, in particular to a photocurable acrylate 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 photocurable acrylate coating for ceramics with good gloss, high hardness, fast drying and high impact strength. Contents of the invention [0003] Technical issues solved: [0004] Aiming at the above ...
