The invention belongs to the field of brake pad materials, and particularly relates to a preparation method of a ceramic alloy composite wear-resistant and high-temperature-resistant brake pad, which comprises the following steps: adding activated polyurethane foam into slurry, stirring, fully dipping, coating to prepare silicon carbide ceramic powder, carrying out amination modification on the silicon carbide ceramic powder, and drying to obtain the ceramic alloy composite wear-resistant and high-temperature-resistant brake pad. The zirconium oxide fiber is subjected to carboxylation modification, and the zirconium oxide fiber and the silicon carbide ceramic powder are grafted and combined through amidation reaction, so that the performance is more stable, the defect of weak interface bonding force of the zirconium oxide fiber and the silicon carbide ceramic powder is overcome, the structure is more compact, and the mechanical property is better; meanwhile, zirconium oxide fibers are uniformly and orderly di
