| 摘 要： | 研究不同防老剂对氯化聚乙烯橡胶(CM)性能的影响.结果表明:加入不同防老剂的CM胶料ML和MH减小,t10和t90延长,CM硫化胶的硬度、100％定伸应力和拉伸强度增大,拉断伸长率减小；交联密度随老化时间的延长而呈增大趋势.当防老剂RD用量为2份时,CM硫化胶的耐热氧老化性能最优.

| Abstract: | The effects of different antioxidants on the properties of CM were investigated.The results showed that,the ML and MH of CM compound with different antioxidants decreased,t10 and t90 extended,the hardness,modulus at 100% elongation and tensile strength of CM vulcanizate increased,and the elongation at break decreased.As aging time extended,the crosslink density tended to increase.When the addition level of antioxidant RD was 2 phr,the thermo-oxidative aging resistance of CM vulcanizate was the best. |
