Abstract

The invention relates to the technical field of antirust coatings, in particular to a pipeline antirust coating. The pipeline antirust coating comprises the following components in parts by mass: 100parts of polypropylene; 30-40 parts of talcum powder; 10-14 parts of fumed silica; 2-3 parts of phenylarsine oxide; 1.6-2 parts of phenylhydrazine. The pipeline antirust coating has the effect that volatile gas is not easy to generate, so that the environment is not easy to pollute.

Description

technical field [0001] The invention relates to the technical field of antirust coatings, in particular to a pipeline antirust coating. Background technique [0002] At present, pipes are divided into metal pipes and non-metal pipes. Among them, metal pipes have good physical properties and are easy to process, so they are more commonly used. However, metal pipes are prone to rust, which shortens the life of metal pipes. Therefore, it is usually necessary to use metal pipes The surface is coated with anti-rust paint. [0003] Most of the existing anti-rust coatings are polymer materials, which are usually dissolved by solvents and then applied on metal pipes. After the solvent evaporates, a cured protective film is formed, which prevents moisture and oxygen from eroding metal materials. [0004] The above existing technical solutions have the following defects: when the solvent volatilizes, it will volatilize toxic and odorous gas, which is easy to pollute the environment, ...
