摘　　要：通过动态硫化法制备三元乙丙橡胶(EPDM)/聚丙烯(PP)动态硫化热塑性弹性体(TPV)材料,在固定邵尔A硬度的前提下,研究了硫化剂双叔丁基过氧化二异丙基苯(BIBP)和交联助剂三烯丙基异氰脲酸酯(TAIC)及N,N′-间苯基双马来酰亚胺(HVA 2)对TPV硫化特性、拉伸性能及压缩永久变形的影响。结果表明,添加2份TAIC及0.5份HVA 2,可将硫化剂BIBP用量降至0.5份,并显著提升EPDM/PP TPV材料的拉伸强度,降低材料的压缩永久变形。The thermoplastic elastomer(TPV)of EPDM/PP was prepared by the method of dynamic vulcanization.The effects of the content of curing agent BIBP,the crosslinking agent TAIC and HVA 2 on the curing characteristics,tensile properties and compression set under the premise of fixed shore hardness were investigated.The results show that adding 2 parts of TAIC and 0.5 parts of HVA 2 can reduce the amount of curing agent BIBP to 0.5 parts,and the tensile strength and the compression set of EPDM/PP TPV are significantly improved.
