%X 研究甲基乙烯基硅橡胶(MVQ)/氯化丁基橡胶(CIIR)共混比对共混物性能的影响。结果表明：与CIIR相比，MVQ/CIIR共混物的t<sub>10</sub>(MVQ用量为5份除外)和t<sub>90</sub>缩短，硫化速率增大；邵尔A型硬度、拉伸强度、拉断伸长率和撕裂强度降低，耐热老化性能提高；MVQ用量为0～20份时MVQ/CIIR共混物对芥子气“液-气”的防护时间达到360 min(不透)；MVQ用量为25份时MVQ/CIIR共混物的耐低温性能大幅提高。MVQ/CIIR共混比为15/100左右时MVQ/CIIR共混物的综合性能最佳。;The effect of blending ratio on the properties of MVQ/CIIR blend was investigated.The results showed that，compared with CIIR，t<sub>10</sub> (except for the blend with 5 phr of MVQ) andt<sub>90</sub> of the MVQ/CIIR blend were shortened，the curing rate increased，the Shore A hardness，tensile strength，elongation at break and tear strength decreased，and the thermal aging property was improved.When the addition level of MVQ was 0～20 phr，the protection time of MVQ/CIIR blend against mustard vapor reached 360 min(no permeation detected).When the addition level of MVQ was 25 phr，the low temperature resistance of the blend was improved remarkably.When the MVQ/CIIR blending ratio was about 15/100，the blend possessed optimum comprehensive properties
