Abstract

The invention provides a polyethersulfone antistatic anticorrosion coating, and a preparation method and application thereof, belonging to the technical field of paints. The paint is composed of the following components in parts by mass: 80 parts of thermoplastic polyethersulfone resin, 30 parts of high-temperature-resistant fluororesin, 1.35-3.85 parts of conducting filler and 280 parts of composite solvent and assistant. The preparation method comprises the following steps: mixing the thermoplastic polyethersulfone resin, high-temperature-resistant fluororesin, conducting filler, composite and assistant, stirring at the rate of 500-800 r / min for 30-60 minutes, and grinding at the rate of 3500-5000 r / min for 4-8 hours. The paint provided by the invention has the characteristics of favorable adhesive force with the metal substrate and high acid / alkali corrosion resistance. The alternating-current conductivity of the prepared coating under the frequency of 10<3>Hz is 1.71*10<-8>-3.20*10<-4>S / m. The paint has favorable antistatic capacity and is applicable to electronics, electric appliances, aviation, petrochemical industry and other industries.

Description

technical field [0001] The invention belongs to the technical field of coatings. Background technique [0002] Since static electricity can affect the normal operation of electronic equipment, and sparks caused by static electricity can cause fires and explosions, people have paid more and more attention to the hazards caused by static electricity in recent years. There are usually two ways to eliminate static electricity hazards: one is to prevent the generation of static electricity and solve the static electricity from the source; the other is to neutralize the static electricity that has been generated as soon as possible. However, in many actual productions, especially in large-scale chemical equipment and electronic products, due to the characteristics of the equipment, it is difficult to control the equipment so that no static electricity is generated. This requires us to be able to neutralize the static electricity that has been generated in time, so as to minimize ...
