The present invention discloses a regenerated HIPS/PPO alloy material based on chemical and physical co-modification, which is mainly composed of the following components in parts by mass: waste HIPS 60-70, PPO 30-40, HIPS-based macromolecular chain extender 2-8, elastomer toughening agent 2-10, oxazoline chain extender 0.2-1, and chain-extension catalyst 0.1-0.4. The alloy material uses chemical modification of in-situ chain extension and compatibilization of the macromolecular chain extender to restore a molecular chain structure, improve a phase interface and increase compatibility of the alloy. Through physical modification introduced by adding the elastomer toughening agent, a combined effect of chemical modification and physical modification is exploited, with target properties improved, a regenerated plastic alloy material with an excellent comprehensive property prepared, and the waste fully utilized to achieve energy saving and emission reduction. A method for preparing the above-described alloy material is also disclosed.

The resin molded article includes a main body part configured to be mounted to a car body panel, a cantilever-shaped seal part for sealing a gap in the car body panel, and a hollow tubular-shaped seal part. The seal part is in resilient contact with the car body panel in a state of being mounted to the car body panel. The seal part is molded from a thermoplastic elastomer containing 25 wt % or more of an olefin block copolymer. It is preferable that the thermoplastic elastomer also contains a dynamically crosslinked olefin-based elastomer in addition to the olefin block copolymer.
