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４ｍｉｎ，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。
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.
