Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a wear-resistant epoxy resin coating and a preparation method thereof. Background technique [0002] Epoxy resin is a kind of thermosetting resin with excellent comprehensive performance. This is due to its high stability, good bonding performance, small curing shrinkage and excellent electrical insulation, so it can be widely used in materials, machinery, chemical industry, etc. and electrical and electronic fields. With the continuous development of its application fields, the wear resistance of epoxy resin has gradually attracted attention. [0003] The solution currently adopted is mainly to add fibers or micron inorganic particles to the epoxy resin for filling and reinforcement, but this method will greatly increase the viscosity of the epoxy resin, thereby making the fluidity of the epoxy resin poor and difficult to process. [0004] Therefore, it is necessa...
