Problems solved by technology

[0005] Epoxy resin (EP), as a commonly used resin matrix, has excellent adhesive properties, mechanical strength, heat resistance and dielectric properties, but it contains a large amount of epoxy groups after curing, and the crosslinking density is too high. The resulting products are brittle, and have poor impact resistance, electrical conductivity and thermal conductivity, which leads to coatings, construction plastics, rubber products, etc., when they are used outdoors to withstand the test of weather, such as light, cold and heat, wind and rain, bacteria, etc. The comprehensive damage caused by etc., its tolerance is poor
