Problems solved by technology

[0004] The poor dispersion and poor adhesion of polyaniline in polyaniline / resin coatings also greatly reduce the anti-corrosion performance of polyaniline. At the same time, the physical anti-penetration ability of polyaniline is far from meeting the requirements of harsh service conditions.

Abstract

The invention discloses scouring resistant alloy steel anticorrosive paint. The scouring resistant alloy steel anticorrosive paint is prepared from the following raw materials in parts by weight: 0.5-1 part of sodium borate, 2-3 parts of polyisobutylene, 1-2 parts of butylmercaptooxo-stannane, 0.1-0.4 part of 2-mercaptobenziMidazole, 50-60 parts of aniline, 30-40 parts of pyrrole, 7-9 parts of sulphosalicylic acid, 3-4 parts of epoxy resin E51, 1.3-2 parts of ammonium persulfate, 4-6 parts of molybdic acid, 3-5 parts of polyamide resin, 160-170 parts of n-butanol, 20-30 parts of ethylene glycol monobutyl ether, 2-3 parts of ammonium metaboragte, 0.7-1 part of alkenyl succinic anhydride, 1-2 parts of hydroxyethyl acrylate, 0.8-2 parts of benzyltrimethylammonium chloride and 0.6-1 part of aluminum stearate. The paint disclosed by the invention can form a hard paint film on a base material, and has good scouring resistance.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a brush-resistant alloy steel anti-corrosion coating and a preparation method thereof. Background technique [0002] In recent years, polyaniline, as a new type of conductive polymer material, has attracted more and more attention. Its synthesis process is simple, no pollution to the environment, low cost, and has stable thermodynamic and chemical properties, so that it has a wide range of applications in various fields. In particular, its excellent anti-corrosion performance makes it widely used in the field of anti-corrosion. However, its weak adhesion and poor solubility of the paint film have greatly restricted its application. If the excellent chemical corrosion resistance of polyaniline is combined with the excellent adhesion and mechanical properties of epoxy resin to prepare blended coatings, this will greatly improve the anti-corrosion ability of epoxy ...
