Abstract

The invention discloses a zinc-rich anticorrosion coating. The zinc-rich anticorrosion coating is mainly prepared from a mixture of a component A and a component B in a mass ratio being (3.5-6):1, wherein the component A comprises the following raw materials in parts by mass: 100 parts of inorganic nano-zinc powder, 45-75 parts of bisphenol S epoxy resin, 20-35 parts of fumed silica, 10-25 parts of phenolic epoxy resin, 15-20 parts of hydrogenated bisphenol A epoxy resin, 5-10 parts of tetrabromobisphenol A resin, 6-15 parts of diglycidyl ortho-phthalate and 0.5-1.5 parts of a leveling agent;the component B comprises the following raw materials in parts by mass: 50-65 parts of aminohydrocarbyl silicone oil, 15-25 parts of polyaniline, 5-10 parts of graphene nanoplatelets, 5-8 parts of boron-containing polysilane, 1-3 parts of a defoaming agent and 3-5 parts of a wetting and dispersing agent. The coating has the following beneficial effects: (1) electrical conductivity of polymers in the coating is enhanced; (2) corrosion resistance is excellent; (3) physical properties of the coating are good.

Description

technical field [0001] The invention relates to a paint, in particular to a zinc-rich anticorrosion paint. Background technique [0002] Organic zinc-rich coatings: organic zinc-rich coatings often use epoxy resins, chlorinated rubber, vinyl resins and polyurethane resins as film-forming base materials. The most commonly used is epoxy zinc-rich paint, among which polyamide cured epoxy zinc-rich primer is the most widely used variety in organic zinc-rich primer. The SSPC Paint-20 of the American Steel Structure Coating Association stipulates that the zinc powder of organic zinc-rich coatings should account for no less than 77% of the dry film mass, and the zinc powder of inorganic zinc-rich coatings should account for no less than 74% of the dry film mass. The film is conductive. In addition, the bonding property of organic resin is better than that of inorganic resin, which also provides a better guarantee for the adhesion of high-content zinc powder. [0003] The main an...
