Description

technical field [0001] The invention relates to the technical field of materials for metal steel pipes, in particular to an antirust paint for metal steel pipes. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. Mainly divided into two categories of physical and chemical antirust paint. The former relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical antirust effect of antirust pigments, such as 200 Solvent oil, zinc yellow antirust paint, etc. Used for rust prevention of bridges, ships, pipelines and other metals. No. 200 solvent oil antirust paint is a kind of paint mixed with No. 200 solvent oil and drying oil. It has good permeability and wettability, soft paint film and stro...
