摘　　要：以三元乙丙橡胶(EPDM)为基胶,二氧化硅为成核剂,对比探究了二氧化硅化学改性发泡剂AC和物理改性发泡剂AC对EPDM发泡材料性能的影响。结果表明,引入成核剂可使EPDM发泡材料泡孔均匀性变好,尺寸更加均一;化学改性发泡剂优于物理改性发泡剂。Using ethylene propylene diene monomer(EPDM)as the base rubber and silica as nucleating agent,the effects of silica chemical modified foaming agent AC and physical modified foaming agent AC on the properties of EPDM foaming materials were investigated.The results showed that the addition of nucleating agent could make the cell uniformity of EPDM foam materials better and the size more uniform.The chemical modified foaming agent was superior to the physical modified foaming agent.
