摘要
研究了第3单体VNB对三元乙丙橡胶(EPDM)耐高温性能的影响。结果表明,VNB型EPDM高温压缩永久变形长时间保持率最好,高温力学性能整体保持率好于ENB型和DCPD型EPDM,耐热氧老化性能最优,特别适用于高温使用工况的密封垫片。
Effects of the third monomer VNB on high temperature performance of EPDM were reasched. The results showed that the long time retention of high temperature compression set of VNB EPDM was optimum , the high temperature mechanical properties retention was better than that of ENB EPDM or DCPD EPDM ,the heat oxygen aging resistance was optimum ,it was specially suitable for the seal used at high temperature.
