Novel special derusting and rust-preventing paint

Abstract

The invention discloses a novel special derusting and rust-preventing paint. According to the formula, the paint is prepared from the following raw materials in parts by weight: 5-8 parts of polyvinylpyrrolidone, 10-12 parts of rosin resin, 8-10 parts of polyester resin, 10-12 parts of epoxy resin, 6-8 parts of ethyl orthosilicate, 5-8 parts of polyacrylamide, 5-6 parts of silica, 5-8 parts of polypropylene, 3-5 parts of polyvinyl chloride, 6-8 parts of acetic acid, 3-5 parts of diethyl ether, 3-5 parts of ephedrine, 2-4 parts of ethyl acetate, 3-5 parts of benzoic acid, 3-6 parts of carboxylic acid, 3-6 parts of sodium citrate, 2-3 parts of potassium sorbate, 1-3 parts of sodium pyrosulfate, 2-3 parts of diatom ooze, 3-6 parts of titanium dioxide, 3-6 parts of calcium carbonate, 2-4 parts of sodium bicarbonate, 3-5 parts of ferroferric oxide, 3-5 parts of magnesium oxide, 2-3 parts of alumina, 3-5 parts of zinc phosphate, 4-5 parts of sodium dichromate, 2-3 parts of vanadium pentoxide, 1-3 parts of phosphorus pentoxide and 25-30 parts of deionized water. The paint is excellent in adhesion with the metal surface, long in service life for rust prevention, quick in drying, low in cost and good in high-temperature resistance, and can be directly sprayed or coated on the surface of rusting steel.

Description

technical field [0001] The invention relates to the technical field of rust-removing and anti-rust paint, in particular to a novel special rust-removing and anti-rust paint for steel components. Background technique [0002] At present, metal corrosion and rust have become a major disaster in the national economy, and improving the technical level of rust removal and rust prevention is an important research topic for countries all over the world. At present, the metal surface derusting treatment in my country still adopts traditional mechanical methods, which not only have low efficiency, high cost, and pollute the environment. With the development of industry, the problem of rust removal of various steel parts such as machinery, vehicles, ships, bridges, and pipelines has become increasingly prominent. Other rust removal work is labor-intensive, and it is not easy to completely remove, and the quality of rust prevention cannot be guaranteed. At present, although there are...
