摘　　要：以金属氧化物硫化体系对自制氯磺化聚乙烯(CSM)进行了硫化,得到CSM硫化胶(SCSM),分别考察了金属氧化物硫化体系中PbO用量对CSM橡胶的热性能、动态力学等性能的影响。结果表明,PbO用量增加时,拉伸强度逐渐增强,当其用量达到40份时,S-CSM的拉伸强度都能达到25MPa以上,断裂伸长率达到150%以上。PbO和炭黑用量对S-CSM的热稳定性影响并不明显。随着PbO用量的增加,S-CSM的玻璃化转变温度和储能模量也随之增大。Sulfuration chlorosulfonated polyethylenes（S-CSM）were prepared by metal oxide vulcanization system vulcanization CSM.The thermal properties and dynamic mechanical performance were investigated through adjusting PbO content.The results showed that the tensile strength of SCSM improved with PbO content increasing.The tensile strength and elongation of S-CSM reached 25 MPa and 150%respectively,when PbO content achieved 40 fractions.The influence of thermal stability of PbO and CB content on S-CSM was not obvious.The Dynamic mechanical analyzer（DMA）results indicated that Tgand storage modulus of S-CSM increased with PbO content enhancing.
