中文摘要：

研究增塑剂DOP、DOS和氯化石蜡对氯磺化聚乙烯橡胶（CSM）性能的影响。结果表明：加入不同品种增塑剂或随着增塑剂用量的增大，CSM胶料的门尼粘度下降，t10和t90延长，交联程度降低，硫化胶的拉断伸长率增大，其他物理性能和耐热空气老化性能均下降，氧指数呈减小趋势，耐低温性能提高；增塑剂DOS对CSM硫化胶耐低温性能的改善效果最大，增塑剂DOP次之，氯化石蜡最小；增塑剂DOS用量为40份的CSM硫化胶达到了耐严寒的要求。

英文摘要：

The effects of plasticizer DOP,DOS and chlorinated paraffin on the properties of chloro- sulfonated polyethylene rubber（CSM） were investigated. The results showed that,as the addition level of plasticizer increased, the Mooney viscosity of CSM compound decreased, the t10 and t90 were extended, the crosslinking degree decreased, the elongation at break of the vulcanizates increased,the other physical properties and thermal aging property decreased, the oxygen index tended to decrease, and the low temperature resistance was improved. DOS plasticized CSM vulcanizates showed the best low temperature resistance,while chlorinated paraffin plasticized CSM vulcanizates showed the smal- lest improvement. The CSM vulcanizates with 40 phr DOS met the application requirements in the severe cold conditions.
