Abstract

The invention discloses a titanate alloy steel anticorrosive coating. The titanate alloy steel anticorrosive coating consists of the following raw materials in parts by weight: tetrabutyl titanate 4-6 parts, polysorbate 80 0.8-1 part, aniline 50-60 parts, pyrroles 30-40 parts, sulfosalicylic acid 7-9 parts, epoxy resin E51 3-4 parts, ammonium persulfate 1.3-2 parts, molybdic acid 4-6 parts, polyamide resin 3-5 parts, n-butyl alcohol 160-170 parts, butyl glycol ether 20-30 parts, polyadipate ethylene glycol 3-5 parts, zirconium ammonium carbonate 0.7-1 part, methyl stannum mercaptide 1-2 parts, kt101 titanate coupling agent 0.6-1 part, octyl and decyl glycerate 0.2-0.4 part, and aluminium triphosphate 1.6-2 parts. The titanate alloy steel anticorrosive coating is modified by the titanate coupling agent, and therefore, the surface hydrophobicity and the weather fastness of the finished coating are improved effectively.

Description

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