Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an anti-corrosion automobile finish paint. Background technique [0002] Automobile is a kind of high-end consumer goods. With the improvement of people's living standards, it will also bring a more powerful development to the automobile industry. In daily life, cars are often exposed to wind and sun. On the one hand, they are prone to damage such as fading and peeling, and on the other hand, they are also vulnerable to various corrosions, such as acid rain. At present, major automobile manufacturers are doing more and more research on automotive topcoats, but there is no effective measure to prevent the peeling of automotive topcoats. In other words, the adhesion of automotive topcoats needs to be improved to be more effective Good for what people ask for. Contents of the invention [0003] In order to solve the above problems, the present invention provides an anti-corr...
