Problems solved by technology

Since the molecular structure does not contain double bonds and the chlorine atoms are randomly distributed, it has good weather resistance, ozone resistance, heat aging resistance, flame resistance, chemical resistance and oil resistance, but it is a single component The coating of the film is very brittle and has poor adhesion, so it needs to be compounded and improved in the actual application process
In addition, the existing structural design has higher requirements on the impact resistance of coatings

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-corrosion and impact-resistant coating and a preparation method thereof. Background technique [0002] The housings and other components of many instruments need to be coated with a layer of paint to improve their stability and life. At present, most of the common coatings on the market have the problems of general corrosion resistance and weak stability. Highly chlorinated polyethylene has a high chlorine content, also known as HCPE resin. Small white light particles, chlorine content > 61%, thermal decomposition temperature > 130°C, thermal stability time 180°C > 3min. Since the molecular structure does not contain double bonds and the chlorine atoms are randomly distributed, it has good weather resistance, ozone resistance, heat aging resistance, flame resistance, chemical resistance and oil resistance, but it is a single component The coating ...
