The present invention relates to a high‑strength and high‑resilience TPV elastomer and a preparation method thereof. The components include synthetic rubber, thermoplastic elastomer, white oil, inorganic filler, crosslinking agent, co‑crosslinking agent, antioxidant, lubricant, light stabilizer, etc. The preparation method is as follows: first, uniformly mix synthetic rubber, polyolefin resin, thermoplastic elastomer and inorganic filler in a high‑speed mixer, then extrude and pelletize through a twin‑screw extruder to obtain an intermediate; then add crosslinking agent and co‑crosslinking agent to the obtained intermediate, mix uniformly in a high‑speed mixer, and perform dynamic vulcanization and pelletization in a twin‑screw extruder. During pelletization, white oil is added through a liquid feeding port to prepare a high‑strength and high‑resilience thermoplastic vulcanizate. The thermoplastic vulcanizate provided by the present invention has a simple preparation method, can greatly improve the tensile strength and resilience of TPV materials, and is of great significance for broadening the application fields of TPV elastomers.
