The invention discloses high-temperature (800 DEG C) wear-resistant paint and a preparation method thereof. The high-temperature wear-resistant paint comprises a component 1 and a component 2, wherein the component 1 is prepared by mixing a component A and a component B; the component A in the component 1 comprises the following components: black silicon carbide, fine-grain aluminum oxide, dispersing agent, zinc oxide, modified epoxy resin, flatting agent and an auxiliary material; the component B in the component 1 comprises the following components: organic silicon modified epoxy resin, a filler, antimony trioxide, film-forming assistant and thickener; and the component 2 is curing agent and coupling agent. The high-temperature (800 DEG C) wear-resistant paint is prepared by the following steps: mixing the component A and the component B in the component 1, and curing the component 1 with the component 2. The high-temperature wear-resistant paint is prepared by compounding the double components, has excellent high temperature resistance and wear resistance, and also has the fine properties of favorable hardness, high heat stability, ductility, workability and the like. The invention also designs the method for preparing the high-temperature wear-resistant paint. The preparation method is simple and low in cost.
