| 中文摘要: |
| 研究三元乙丙橡胶（EPDM）/聚丙烯（PP）/聚烯烃弹性体（POE）热塑性弹性体的性能。结果表明：随着溴化辛基酚醛硫化树脂SP-1055用量增大，EPDM/PP/POE的硫化程度增大，硬度呈上升趋势，拉断伸长率、拉断永久变形和压缩永久变形呈减小趋势，定伸应力和拉伸强度先提高后降低；使用POE810，EPDM/PP/POE热塑性弹性体的100%定伸应力、拉伸强度和拉断永久变形较大，压缩永久变形较低，综合物理性能较好。 |
| 英文摘要: |
| The properties of EPDM/PP/POE thermoplastic elastomer were investigated in this study.Firstly，the addition level of brominated octyl phenolic curing resin SP-1055 was studied.It was found that with the increase of addition level of SP-1055，the cross-link degree of EPDM/PP/POE increased，the hardness also increased，while the elongation at break，permanent tensile set and compression set all decreased.Secondly，the experimental test results showed that by using POE810，the EPDM/PP/POE possessed good overall physical properties，such as large tensile modulus at 100% elongation，tensile strength and permanent tensile set，and low compression set. |
