| 摘 要： | 考察了硫黄用量和聚合物共混比对动态硫化ＥＰＤＭ／ＰＰ热塑性弹性体性能的影响。结果表明，随着硫黄用量增大，ＥＰＤＭ／Ｐ共混物的拉伸强度、１００％定伸应力和扯断伸长率先增大后减小、硬度有所增大，随着ＰＰ用量的增大，ＥＰＤＭ／ＰＰ共混物的拉伸强度、１００％定伸应力和硬度均有所增大，扯断伸长率也先大后减小。ＰＰ用量的变化对这些性能的影响更显。

| Abstract: | The influence of the sulfur level and the rubber/plastics ratio on the mechanical properties of dynamically vulcanized EPDM/PP thermoplastic elastomers was investigated.The results showed that the tensile strength,the modulus at 100% elongation,and the elongation at break of EPDM/PP blends increased at first and then decreased as the sulfur level increased;the tensile strength,the modulus at 100% elongation and the hardness of EPDM/PP blends increased,and their elongation at break increased at first and then decreased as the PP proportion increased;and the PP proportion had more significant effect on the mechanical properties of the blends. |
