摘要
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t10（MVQ用量为5份除外）和t90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,t10 （except for the blend with 5 phr of MVQ） and t90 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.
