Problems solved by technology

At present, there are still problems that need to be solved urgently in antistatic anticorrosion coatings: when the coating is soaked in water or organic solvents for a long time, the electrostatic conductive components of the coating will be lost with the discharge of water or organic solvents, resulting in a decrease in the surface resistivity of the coating and a long-term loss. Effective anti-static and anti-corrosion effect

Abstract

The invention discloses an antistatic anticorrosion paint for petroleum pipelines. The antistatic anticorrosion paint is prepared by stirring the following raw materials of: by weight, 50-55 parts of an epoxy resin, 36 parts of polyaspartic ester, 26 parts of an static conductive auxiliary agent, 20 parts of di-n-butyl, 12 parts of polyethyleneglycol diglycidylether, 23-25 parts of methyl methacrylate, 2-5 parts of acetone, 14 parts of styrene, and 2.5 parts of a thickening agent. The invention is long-acting and antistatic, has strong adhesive force and excellent anticorrosion performance, and requires no special spraying equipment for construction.

Description

technical field [0001] The invention relates to an antistatic anticorrosion paint for petroleum pipelines, which belongs to the technical field of chemical paints. technical background [0002] In recent years, the harm of static electricity has been paid attention to by people. Sparks caused by static electricity can easily cause fire and explosion, and static electricity will affect the normal operation of electronic equipment. Therefore, antistatic coatings are more and more widely used in oil storage pipeline coating. At present, there are still problems that need to be solved urgently in antistatic anticorrosion coatings: when the coating is immersed in water or organic solvents for a long time, the electrostatic conductive components of the coating will be lost with the discharge of water or organic solvents, resulting in a decrease in the surface resistivity of the coating and loss of long-term Effective anti-static anti-corrosion effect.
