| 摘 要： | 用动态硫化方法制备也ＮＢＲ／ＨＤＰＥ共混型热塑弹性体，电子显微镜研究其形态表明，尽管ＮＢＲ的用量超过了ＨＤＰＥ，但ＮＢＲ仍为分散相，ＨＤＰＥ为连续相，使该材料表现出热塑性。应力－应变性能和动态力学研究表明，该产品在室浊下表现出良好的弹性行为，且力学性能较好，但永久变形较大。

| Abstract: | NBR/HDE thermoplastic elastomer was prepared by dynamically vulcanized. The morpholrey from scanning and transmission elastron microscopy (SEM, TEM) showed that NBR was dispersed in HDPE plastic matrix although the proportion 0f NBR was much than that of HDPE, this was the arn why it had both elasticity and plasticity. Stress - strain behavior and dynamic mechanical test indicated that NBR/HDPE (65/35) thermoplastic elastomer had good mechanical and elastic properties at on tamperature, but its permanent set was poor. |
