Alloy steel bacteria-inhibiting and anti-corrosive coating and preparation method thereof

Abstract

The invention discloses an alloy steel bacteria-inhibiting and anti-corrosive coating. The alloy bacteria-inhibiting and anti-corrosive coating is prepared from the following raw materials in parts by weight: 0.1 to 0.2 part of sodium benzoate, 0.3 to 0.5 part of calcium benzoate, 1 to 2 parts of calcium ricinoleate, 0.4 to 1 parts of sodium diacetate, 2 to 4 parts of calcium linoleate, 0.4 to 1 part of polyvinyl butyral, 2 to 4 parts of pyromellitic acid dianhydride, 50 to 60 parts of aniline, 30 to 40 parts of pyrrole, 7 to 9 parts of sulfosalicylic acid, 3 to 4 parts of epoxy reisn 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-butyl alcohol, 20 to 30 parts of butyl cellosolve, 1.8 to 2 parts of sodium carboxymethyl cellulose, and 5 to 7 parts of polyvinylpyrrolidone. The alloy bacteria-inhibiting and anti-corrosive coating has the advantage that by adding the sodium benzoate, the calcium benzoate, the sodium diacetate and the like, the bacteria-inhibiting property of the coating is effectively improved.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to an alloy steel antibacterial 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 r...

AI Technical Summary

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.
