▎ 摘  要

NOVELTY - Composition for antistatic EPDM/PP-TPV material, contains 45-65 wt.% EPDM, 15-25 wt.% PP, 10-30 wt.% environmentally friendly paraffin oil, 1-3 wt.% graphene, 1-3 wt.% maleic anhydride grafted polypropylene, 0.3-0.6 wt.% erucamide, 0.5-1 wt.% crosslinker, 2-4 wt.% co-crosslinker and 0.3-0.6 wt.% antioxidant. USE - The antistatic EPDM/PP TPV material is used as a sealing material in automobiles, construction or household appliances ADVANTAGE - The mechanical properties of the antistatic EPDM/PP TPV material are greatly improved, and the surface resistivity can be effectively reduced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing antistatic EPDM/PP TPV material, comprising: (1) carrying out banburying of graphene and maleic anhydride grafted polypropylene after extrusion granulation to obtain graphene mother; (2) rubber-plastic blending of EPDM, PP, graphene master batch, erucamide, antioxidant and environment-friendly paraffin oil to obtain rubber-plastic master batch; (iii) dynamically vulcanizing the rubber-plastic master batch particles, auxiliary crosslinking agent and crosslinking agent; where, the graphene, the maleic anhydride grafted polypropylene; and (2) antistatic EPDM/PP-TPV material.
