The invention relates to the technical field of polymer materials, and discloses a high-temperature-resistant flame-retardant thermoplastic elastomer and a preparation method thereof. In the invention, hydrogenated styrene-butadiene block copolymer, paraffin oil, polyethylene wax and carbon nanotube modified benzoxazine are extruded and pelletized in a twin-screw extruder, and then the pellets are molded in a flat vulcanizing machine to obtain the high-temperature-resistant flame-retardant thermoplastic elastomer. Nitrogen, sulfur, guanidine, boron and benzoxazine structures in carbon nanotube modified benzoxazine all have good flame retardant effects. The carbon nanotubes in carbon nanotube modified benzoxazine themselves have good high-temperature resistance and flame retardant effects, as well as good mechanical properties, and the adamantane contained therein also has good mechanical properties. Adding them into the thermoplastic elastomer improves its performance.
