Abstract

The invention discloses a preparation method of a wear-resistant, heat-insulation and corrosion-resistant powder coating. The powder coating is prepared from the following raw materials: benzoxazine resin, epoxy resin, chlorinated polyether, carboxylated-terminated acrylonitrile-polybutadiene rubber, a curing agent, barite powder and wollastonite powder. The wear-resistant, heat-insulation and corrosion-resistant powder coating can be prepared by processes such as melting, mixing and extruding, cooling for tabletting, crushing and sieving and has excellent wear and corrosion resistance and heat insulation properties, the surface of a processed coating meets the national and industrial standards on the aspects such as adhesive force, flexibility, impact strength, smoothness, hardness and chemical resistance, and the wear-resistant, heat-insulation and corrosion-resistant powder coating is low in curing temperature, convenient to use and capable of reducing the cost.

Description

technical field

[0001] The invention relates to the technical field of powder coatings, in particular to a preparation method of wear-resistant, heat-insulating and anti-corrosion powder coatings. Background technique

[0002] Epoxy powder coatings are thermosetting powder coatings developed in the last century. Its film-forming substance epoxy resin has excellent physical and mechanical properties, and the coating film has good adhesion to the substrate, good electrical insulation, and excellent chemical corrosion resistance. It has been widely used in the internal and external anti-corrosion of chemical industry, electrical appliances, instruments, machinery and transportation pipelines, and occupies a leading position in anti-corrosion coatings. However, due to the characteristics of epoxy resin itself, epoxy powder coatings have poor weather resistance and wear resistance in practical applications, and the coating film is easy to pulverize, so it is not suitable for out...
