The invention belongs to sealing material technology, and particularly relates to a low-temperature resistant and wear-resistant thermoplastic sealing material, its preparation method and application. The preparation steps: Blend polyolefin elastomer, long-chain nylon elastomer, compatibilizer, optional co-crosslinking agent, lubricant and other additives to form a mixture; extrude and granulate the blend via a twin-screw extruder to obtain composite masterbatch; mix the masterbatch with optional crosslinking agent, and perform dynamic vulcanization in a twin-screw extruder to produce thermoplastic sealing pellets. The final material integrates excellent mechanical properties, low-temperature toughness and wear resistance.
