Problems solved by technology

However, the compatibility between carbon black and silicone resin is poor, and it is difficult to disperse evenly. At the same time, the color of the product obtained from carbon black is not loved by people because it is black.
[0003] In the field of anti-corrosion coatings, various fillers are added, but the effect cannot meet the market demand, and cannot meet the product requirements of hardness, adhesion, impact resistance, flexibility and water resistance that people pursue.

Abstract

The invention relates to a polyaniline-modified zinc-containing anti-corrosive coating. The polyaniline-modified zinc-containing anti-corrosive coating comprises the following raw materials in parts by weight: 50 to 80 parts of graphene, 10 to 15 parts of polypropylene vinyl acetate, 20 to 38 parts of epoxy resin, 70 to 210 parts of zinc powder, 17 to 40 parts of talcum powder, 10 to 20 parts of defoaming agent, 5 to 8 parts of flatting agent, 5 to 8 parts of curing agent, 30 to 70 parts of filling agent, and 10 to 15 parts of polyaniline-based nanometer material. The polyaniline-modified zinc-containing anti-corrosive coating has good waterproof property, and is suitable for protecting marine wind power equipment under marine environments, and is also suitable for long-time corrosion resistance of land steel structures of inland pipe diameters.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to a zinc-containing anticorrosion coating modified by polyaniline. Background technique [0002] There are various types in the prior art, and CN101407650A proposes to blend oligomers, reactive diluents, polyaniline, fillers, photoinitiators, and additives, and then obtain ultraviolet light by stirring, grinding, and filtering. Cured polyaniline anti-corrosion coating, the curing of the coating obtained in this patent is limited by the penetration depth of ultraviolet light, and it is easy to cure incompletely, resulting in poor coating performance; Chinese patent CN101418146A proposes to use oligomers, reactive diluents, polyurethane Polyols, polyaniline, fillers, photoinitiators and additives are used to prepare UV-heat dual-curing polyaniline anti-corrosion coatings. This patent improves the performance of the coating, but the diluent is still an organic solvent, which is n...
