The invention relates to the technical field of polymer materials, and discloses an oil-resistant high-temperature-resistant thermoplastic vulcanizate and a preparation method thereof. In the invention, terpolypropylene, EPDM rubber, polyphenylene sulfide modified benzoxazine, graphene modified maleimide, paraffin oil, N‑phenylaniline, vulcanized resin SP1045 and trimethylolalkane tetraacrylate are extruded and pelletized in a twin-screw extruder, and then the pellets are molded in a flat vulcanizing machine to obtain the oil-resistant high-temperature-resistant thermoplastic vulcanizate. Sulfur, triazinyl, benzoxazine groups and graphene structures contained in polyphenylene sulfide modified benzoxazine and graphene modified maleimide all have good flame retardant effects, which together form a flame retardant system for synergistic flame retardancy; maleimide, ferrocene and graphene groups in polyphenylene sulfide and graphene modified maleimide synergistically resist oil, achieving a good oil resistance effect.
