Temperature-resistant wear-resistant coating and preparation method thereof

The invention provides a temperature-resistant wear-resistant coating and a preparation method thereof, belongs to the technical field of two-component epoxy adhesives, and mainly solves the problems of poor temperature resistance and wear resistance of coatings in the prior art. The temperature-resistant wear-resistant coating is mainly composed of A and B two components, the component A comprises the following components: 10%-30% of epoxy resin, 5%-30% of modified epoxy resin, 3%-10% of a diluent, 10%-30% of silicon carbide, 1%-5% of fumed silica and 40%-70% of a high alumina ball; the component B comprises the following components: 20%-30% of a curing agent, 0%-3% of a promoter, 1%-5% of a silane coupling agent, 10%-30% of the silicon carbide, 1%-5% of the fumed silica and 40%-60% of the high alumina ball; the weight ratio of component A to component B is 4:1. The temperature-resistant wear-resistant coating has the advantages of good erosion wear resistance, simple coating process and low cost, is mainly used on the surface of a workpiece working in slurry erosion wear working conditions, and is also used in corrosion and wear surface repair.
