Abstract

The invention relates to a powder coating for improving wear resistance and wear reduction of the surface of an aluminum profile. According to the invention, modified epoxy resin prepared by introducing polyfunctional groups into epoxy resin improves heat resistance and corrosion resistance and shortens curing time; melt extrusion is performed in order to further make up the defects of insufficient adhesive force and no wear resistance; an anti-scratching agent is added, so binding force to the aluminum profile is strong, and protective performance cannot be gradually reduced along with the prolonging of the service time of the coating. The powder coating prepared by the invention is applied to the surface of the aluminum profile, and has good associativity; and when the surface of the aluminum profile is coated with the powder coating, the powder coating shows excellent adhesion capability, has high mechanical strength, good weather resistance, chemical resistance, scratch resistanceand scuff resistance, cannot be damaged and lose efficacy, presents very strong wear resistance and reduction performance and high chemical corrosion resistance, plays an excellent protection role invarious complex environments, can bear erosive wear of gas, solid and liquid, has excellent outdoor stability, and prolongs the service life of the aluminum profile.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a powder paint for improving the wear resistance of the surface of an aluminum profile. Background technique [0002] Aluminum and its aluminum alloys, because of their good physical and chemical properties, as well as the stable, continuous and rapid development of my country's national economy and high-tech, have promoted the rapid development of my country's aluminum smelting and aluminum profile processing industries. [0003] Compared with iron, aluminum profiles have better corrosion resistance. However, the texture is soft and easy to wear, and it will be eroded by liquid flow and sediment, which will accelerate wear and corrosion. The phenomenon of erosion and wear has widely existed in our life and industrial production, and it is also one of the important reasons that mainly cause damage to materials and affect the performance of products and equipment. There...
