Problems solved by technology

[0002] Automobile chassis coating is also called automobile chassis armor. Its scientific name is automobile chassis anti-collision, anti-rust and sound-proof primer. It is a high-tech adhesive rubber asphalt coating. Spray on the exposed parts of the vehicle chassis, wheels, fuel tanks, car lower panels, trunks, etc., and form a firm elastic protective layer after quick drying, which can prevent the impact of flying stones and gravel, and avoid moisture, acid rain, and salt on the metal of the vehicle chassis. to prevent the chassis from rusting and rusting, and to protect the driving safety of the car owner, while the automobile chassis coating is often exposed to corrosive substances such as mud during use. The oxidation resistance is essential, but the existing automobile chassis coatings cannot effectively resist oxidation and corrosion. In order to improve the oxidation resistance and corrosion resistance of automobile chassis coatings, a water-based fluorine-modified polyester Preparation Technology of Oxidative Automobile Chassis Coating
