Abstract

The invention discloses a silver wear-resisting powder coating. The silver wear-resisting powder coating comprises, by mass, 25-30 parts of epoxy resin, 40-50 parts of polyester resin, 0.5-1.5 parts of flatting agent, 0.5-0.8 part of wetting agent, 0.3-0.6 part of benzoin, 20-25 parts of barium sulfate, 0.3-0.5 part of hardening agent, 0.2-0.5 part of charging additive, 0.5-0.8 part of silver powder directional alignment agent, 2-3 parts of titanium dioxide and 0.01-0.03 part of carbon black. The surface of the silver wear-resisting powder coating can be as hard as Zhonghua pencils 5H in use, the scratch resistance of the surface is improved greatly, and meanwhile, surface glossiness is high.

Description

technical field [0001] The invention relates to a silver wear-resistant powder coating capable of improving the anti-scratch performance of the silver surface and a method for making and using the same. Background technique [0002] Paint is a material that is applied to the surface of the object to be coated and can form a firmly adhered continuous film. [0003] The invention relates to a powder coating, which is a coating containing 100% solid content, and has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. [0004] Powder coatings are widely used in: 1. Decorative protective coating, used for housings and parts of household appliances, metal furniture, automobiles, instruments, bicycles, sewing machines, electromechanical equipment, light industrial equipment, agricultural machinery, construction hardware, etc. ;2. Insulation and moisture-proof coating, applied to tr...
