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 flame-retarding alloy steel anti-corrosive coating composed of, by weight, 0.7-1 part of saturated stearamide, 1-2 parts of benzyltriphenyl phosphonium chloride, 50-60 parts of aniline, 30-40 parts of pyrrole, 7-9 parts of sulfo-salicylic 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, 170-180 parts of n-butanol, 20-30 parts of ethylene glycol butyl ether, 0.6-2 parts of [beta]-hydroxyalkyl amide, 1-2 parts of ammonium polyphosphate, 0.6-1 part of zinc borate, 0.4-1 part of stannous sulphate, 0.8-1 part of isopropyl palmitate, 1-2 parts of aluminum stearate, and 0.1-0.2 parts of decabromodiphenyl ether. The coating contains the decabromodiphenyl ether, the ammonium polyphosphate, the zinc borate and the like, so that the flame-retarding performance of the coating is improved effectively.
Description
technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a flame-retardant 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 ...
