Description

technical field [0001] The invention relates to the field of paint industry, in particular to a water-based paint for protecting the surface of automobile frames and automobile and motorcycle wheels. Background technique [0002] Now the automobile frame and automobile and motorcycle wheels use traditional solvent-based coatings. This kind of coating is easy to cause flammable, explosive and a large amount of toxic and harmful gases to escape during production, storage, transportation and construction, and there is a great safety hazard. hidden danger, and the escape of organic solvents has greatly damaged the environment. [0003] At present, the annual domestic production of medium and large buses is about 400,000 (including 300,000 medium buses and 100,000 large buses), and the usage of automobile and motorcycle wheels is about 20 million. The area of ​​steel pipes is about 19.2 million square meters, and the area of ​​20 million motorcycle wheels is about 4 million squa...
