Problems solved by technology

[0002] In mechanical equipment, chemical enterprises, building decoration and other industries, the problems of material corrosion, static electricity and electromagnetic interference are very serious, especially in environments with high humidity, high corrosion, high radiation, and high static electricity, corrosion, static electricity and electromagnetic interference are greatly affected It reduces the service performance and life of the product, endangers human health, and sometimes even causes explosions and fires due to corrosion and static electricity, causing economic and life and property losses. Therefore, it is of great significance to do a good job in anti-corrosion, anti-static, and anti-electromagnetic interference.
[0003] The preparation of present perchlorethylene anticorrosion paint is generally to add antirust pigment in perchlorethylene resin, and anticorrosion mechanism is mainly shielding effect, promptly isolates corrosion medium and contacts with base material, although has stronger anticorrosion property, but it is not It has the effect of conducting static electricity and cannot meet the anti-corrosion requirements under special conditions

Abstract

The invention discloses a preparation method of a perchloroethylene anticorrosion static conductive coating, which belongs to the chemical technical field. According to the invention, perchloroethylene is taken as a film former, modified phenolic resin is taken as reinforced resin, conductive graphite treated by a surface modifier is taken as a static conductive agent, the prepared anticorrosion static conductive coating possesses excellent anti-corrosive property, scalelike conductive graphite is added, the surface resistivity of the coating can be controlled at 10<6>-10<7>W, so that the thermal expansion coefficient and shrinkage of the coating are small, and the coating possesses excellent static conductive performance and anti-electromagnetic interference performance. The coating can be used for anticorrosion, flame retardation and static conduction coating on the surface of a steel structure and other metal products under scurviness environment, such as coating with anticorrosionand static conduction on the bridge, ship, train and railway facility, automobile, sea engineering facility, petroleum chemical pipeline equipment, medical health apparatus and the like.
