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 an anticorrosive saponified alloy steel coating, which is prepared from the following raw materials in parts by weight: 1 to 2 parts of aluminum triphosphate, 3 to 5 parts of sodium myrastate, 50 to 60 parts of aniline, 30 to 40 parts of pyrrole, 7 to 9 parts of sulphosalicylic acid, 3 to 4 parts of epoxy resin E51, 1.3 to 2 parts of ammonium persulfate, 4 to 6 parts of molybdic acid, 3 to 5 parts of polyamide resin, 160 to 170 parts of n-butanol, 20 to 30 parts of ethylene glycol butyl ether, 0.2 to 0.4 part of chlorthal dimethyl, 0.1 to 0.2 part of lithium naphthenate, 0.8 to 1 part of diisopropylethanolamine, 1 to 2 parts of beeswax, 1 to 2 parts of dithio-salicylic acid, 0.3 to 1 part of butyltin mercaptide and 6 to 7 parts of pentaerythritol. According to the anticorrosive saponified alloy steel coating, the sodium myrastate and the like are added, so that the flexibility of a finished product coating can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a saponified 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...
