Abstract

The invention discloses a PU (Poly Urethane) wear-resistant coating. The PU wear-resistant coating comprises a component A and a component B which are respectively packaged, wherein the component A is composed of the following materials: polyester resin, fluorinated ethyl silicate, epoxy resin, erucyl amide, polypropylene wax, teflon, corundum, molybdenum disulfide, YCK-5010 and phenyl silicone oil; the component B is a polyurethane prepolymer; the ratio of the component A to the component B is 2:(0.5-1). Because the epoxy resin, the polyester resin and the polyurethane prepolymer which are excellent in toughness are selected, a film-forming material has excellent toughness, and an organically modified inorganic material-fluorinated ethyl silicate is adopted for modification, the hardness and strength of the PU wear-resistant coating are also greatly increased. In the invention, wear-resistant agents including corundum and molybdenum disulfide are used, and various surface lubricating and anti-wear additives such as erucyl amide, YCK-5010 wax, polypropylene wax, teflon and phenyl silicone oil are added into the coating, so that the PU wear-resistant coating disclosed by the invention has excellent wear resistance and bearing and lubrication properties, and can have the effects of protecting surfaces, reducing the friction coefficient and prolonging the service lives of parts.

Description
