The invention belongs to thermosetting epoxy powder insulation anticorrosion paint. It consists of a primer and a top coat, which together form an electrically insulating and anti-corrosion coating. The primer is composed of epoxy resin, curing agent and auxiliary agent; the surface coating is composed of epoxy resin, curing agent, filler and other auxiliary agents; both the primer and the surface coating are made by melt extrusion mixing method Powdered product. The primer coating does not contain or contains less filler, so the adhesion of the formed primer coating is not affected; the surface coating bears the main functions of electrical insulation and anti-corrosion, so the coating of the present invention has strong adhesion, excellent electrical insulation performance, and has Anti-corrosion, anti-rust, anti-mildew, heat-resistant, wear-resistant and other functions, and has the characteristics of low cost.
Description
technical field [0001] The invention belongs to the technical field of powder coatings, and in particular relates to thermosetting epoxy powder insulation anticorrosion coatings. technical background [0002] The paint is applied on the surface of the object to form a solid, strong and continuous coating, which can protect and decorate the coated object, or make it insulating, rust-proof, mildew-proof, heat-resistant, and wear-resistant and other special functions. Patent No. 200410014489.4 Invention Patent "Insulating Powder Coating for Electromagnetic Wires" discloses an insulating powder coating used in electrostatic coating process for electromagnetic wires. A special property of the coating film or coating of this insulating powder coating is electrical insulating properties. The powder coating is composed of resin, curing agent and auxiliary materials, among which the amount of resin and curing agent with higher price accounts for 98%, while the amount of filler with...
