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 a hard alloy steel anticorrosion coating, made from the following materials according to parts by weight: 1-2 parts of sucrose acetate isobutyrate, 0.7-1 part of diphenylimidazoline, 50-60 parts of aniline, 30-40 parts of pyrrole, 7-9 parts of sulfosalicylic 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 butyl alcohol, 20-30 parts of butyl cellosolve, 0.8-2 parts of lauryl dimethyl amine oxide, 0.5-1 part of maleic anhydride, 2-3 parts of barium stearate, 3-5 parts of palm wax, 0.7-1 part of zinc stearate, 2-3 parts of ricinoleic acid, and 0.5-1 part of illite powder. By adding the barium stearate, zinc stearate, illite powder and the like, it is possible to effectively improve surface hardness of the finished coating.
Description
technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a hard 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 resin coati...
