Abstract

The invention discloses an anticorrosive paint containing dimethyl sulfoxide. The anticorrosive paint is composed of a component A and a component B, wherein the component A is prepared from the following raw materials in parts by weight: 84-90 parts of epoxy resin E44, 10-15 parts of high chlorinated polyethylene resin, 10-15 parts of precipitated barium sulfate, 1-2 parts of titanium tetrafluoride, 2-4 parts of sodium monofluorophosphate, 2-4 parts of dimethyl sulfoxide, 2-3 parts of ethylene glycol monobutyl ether, 2-4 parts of ethyl acrylate, 3-5 parts of urea, 2-3 parts of polyacrylamide, 2-3 parts of diethylamine, 2-3 parts of diphenylmethane diisocyanate, 3-5 parts of diisooctyl phthalate, 1-2 parts of ethylene diamine tetra methylene phosphonic acid sodium, 5-7 parts of hydrotalcite, 1-2 parts of dimethylethanolamine, 15-20 parts of compound modifier, 25-30 parts of dimethylbenzene, 10-15 parts of n-butyl acetate, 0.8-1 parts of dilauryl thiodipropionate, 0.8-1 parts of vinyltriethoxysilane and 0.5-1 part of methyl silicone oil. A paint film prepared by the invention has the advantages of good adhesive force to metal, small structure pores, compact structure, good adhesive force, good flexibility, high impact strength and strong corrosion resistance, and plays an efficient protection effect on base metal.

Description

technical field [0001] The invention mainly relates to a coating, in particular to an anticorrosion coating containing dimethyl sulfoxide. Background technique [0002] With the advancement of industrial technology, the use of metal materials is becoming more and more extensive. The corrosion of metals and their components has spread to all fields of the national economy, causing huge losses to human society. In order to reduce the loss of corrosion, people have taken many protective measures, but so far the most common, economical and practical protective measures are coating protection. Among various anti-corrosion technologies, coating anti-corrosion technology is the most widely used. Coating anticorrosion is widely used because of its simple construction, economical application, and not being restricted by equipment area and shape; [0003] Among the many types of coatings, epoxy resin plays an important role in anti-corrosion coatings. It is widely used as a coati...
