Description

Technical field: [0001] The invention relates to a wear-resistant and weather-resistant epoxy resin coating adhesive and a preparation method thereof, belonging to the technical field of adhesives. technical background: [0002] Epoxy resin has good adhesion to most materials, and the cured epoxy resin has the characteristics of high bonding strength, heat resistance, chemical resistance, good dielectric property, and low shrinkage; it is used in bonding and protective coatings. On the one hand, liquid bisphenol A glycidyl ether type epoxy resin is widely used, but because it contains benzene ring, its ultraviolet radiation resistance and aging resistance are poor, and it will gradually change color and pulverize in outdoor environments, making the bonding and protection failure. In addition, when the liquid bisphenol A epoxy resin is cured, the cohesive stress is large, the cured product is hard and brittle, and the acid and alkali resistance and humidity resistance are po...
