Abstract

The invention discloses polyurethane anticorrosive paint, which comprises the following ingredients in parts by weight: 18-25 parts of waterborne polyurethane acrylic ester, 15-20 parts of waterborneepoxy acrylate, 8-18 parts of a silicon acrylic emulsion, 8-18 parts of waterborne polyurethane, 3-8 parts of triethylamine, 4-15 parts of copper sulphide, 3-15 parts of montmorillonoid, 5-12 parts ofelectric conduction mica powder, 8-12 parts of kaolin, 2-6 parts of xylene, 3-8 parts of calcium carbonate, 5-10 parts of zinc oleate, 5-10 parts of diacetone alcohol, 2-8 parts of aluminium triphosphate, 2-8 parts of tetrachloromethane and 2-8 parts of petroleum ether. The paint has the advantages of high adhesive force, very high anti-corrosion performance and good water resistance, and meanwhile, harm on the human body and environment is reduced.

Description

technical field [0001] The invention relates to a coating, in particular to a polyurethane anticorrosion coating. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0003] Traditional anti-corrosion coatings are mainly solvent-based. Due to the large amount of organic volatiles, some products also contain harmful solvents such as benzene and glycol ethers, which cause great harm to the production and construction personnel and relatively damage to the environment. serious. Therefore, water-based coatings have become a research hotspot in recent years. How...
