| 中文摘要: |
| 探讨了共混条件对PVC/再生丁腈橡胶(RNBR)共混型热塑性弹性体性能的影响，重点讨论了硫化方式、共混温度、共混时间、共混设备和返炼次数对其物理性能的影响。实验结果表明，选择共混温度为141 ℃，共混时间为4 min，采用动态硫化工艺可制得物理性能和返炼性较好的PVC/RNBR共混型热塑性弹性体。 |
| 英文摘要: |
| The influence of the blending conditions，especially the curing method，blending temperature and period，blending machine and remilling number on the physical properties of PVC/RNBR(reclaimed NBR)blended thermoplastic elastomer was investigated.The test results showed that a PVC/RNBR blended thermoplastic elastomer with better physical properties and remillability was obtained by using 141 ℃ blending temperature，4 min blending period and dynamic curing technology. |
