| 摘 要： | 采用动态硫化法制备聚丙烯／聚烯烃弹性体／三元乙丙橡胶（PP/POE／EPDM）共混型热塑性弹性体，研究了交联前后不同POE／EPDM并用对比体系力学性能的影响。采用交联剂过氧化二异丙苯（DCP）及DCP／S硫化体系对PP／POE／EPDM体系进行硫化，研究了力学性能的变化。结果表明，EPDM可有效降低材料的硬度和断裂永久变形。助交联剂硫黄（S）对PP／POE／EPDM体系有较好的硫化作用，固定DCP用量为3份，S用量为0．4份时，体系力学性能最佳，交联对体系硬度影响很小。

| Abstract: | The mechanical properties of polyproprene/polyolefin elastomer/ethylene propylene diene monomer （PP/POE/EPDM） thermoplastic elastomer before and after curing by dicumyl peroxide （DCP） were studied in this paper. The influence in mechanical properties of DCP, DCP/S and S/TMTD system on PP/POE/ EPDM blends was compared. The results showed that the addition of EPDM can effectively reduce the hardness and permanent deformation of the blends. Compared with DCP and S/TMTD systems, the DCP/S curing system offeres better performance in mechanical properties of the material. When DCP content is 3 phr, S content is 0.4 phr, the properties of the PP/POE/EPDM system are best. |
