Description

technical field [0001] The invention relates to the field of water-based coatings, in particular, the invention relates to a water-based UV anti-corrosion coating and a preparation method thereof. Background technique [0002] According to statistics, the world releases 20 million tons of hydrocarbons into the atmosphere every year, of which 10 million tons are organic solvents, most of which are produced by the coating industry. Nowadays, the development of environmentally friendly coatings has become an inevitable trend in the development of coatings in the world. After decades of rapid development, water-based coatings have achieved technological breakthroughs. The performance of water-based coatings is not much different from that of traditional solvent-based coatings, and some performances even exceed Solvent based coatings. However, general water-based coatings are highly corrosive to coating equipment, and anti-corrosion linings or stainless steel materials are requi...
