The present invention belongs to the field of polymer material technology, and specifically relates to a method for preparing renewable injection grade TPV materials for automobiles. The preparation method of renewable injection grade TPV material for automobiles includes the following steps: feeding renewable PP, EPDM, and masterbatch particles into a twin-screw extruder, then injecting paraffin oil into the screw, mixing and granulating to obtain semi-finished masterbatch; Feed the semi-finished masterbatch, vulcanizing agent, composite stabilizer, and deodorizing agent into a twin-screw extruder, dynamically vulcanize and vacuum devolatilize them, extrude and granulate them to obtain finished particles, and then dry and deodorize them. First, renewable PP, EPDM, masterbatch particles, and paraffin oil are used to obtain semi-finished masterbatch, which is then combined with vulcanizing agents, deodorizing agents, and other additives to extrude and granulate renewable injection grade TPV materials for automobiles with excellent aging resistance and low odor.
