The invention discloses a polyhexamethylene adipamide-based thermoplastic elastomer, and a preparation method and an application thereof. The polyhexamethylene adipamide-based thermoplastic elastomer comprises the following components in parts by weight: (A), 21-48 parts of polyhexamethylene adipamide, (B), 0-2 parts of heat stabilizer, (C), 0-2 parts of processing agent, (D), 2-15 parts of compatilizer, (E), 10-20 parts of olefin polymer, and (F), 10-40 parts of styrene thermoplastic elastomer. The invention further discloses the preparation method and the application of the polyhexamethylene adipamide-based thermoplastic elastomer. The polyhexamethylene adipamide-based thermoplastic elastomer has very excellent high-temperature bursting properties and low-temperature bursting properties, and can be used for the automobile airbag cover plate. The polyhexamethylene adipamide-based thermoplastic elastomer disclosed by the invention further has good toughness. |
