摘　　要：本工作主要采用应变扫描和温度扫描的方法考察了炭黑(CB)填充顺丁橡胶(BR)/丁苯橡胶(SBR)并用胶的结构与流变行为。研究结果表明:炭黑更易分布于SBR相中,且并未对SBR相的玻璃化转变温度造成显著影响; BR/SBR并用比为80/20时,两者相容性最好;以60℃作为混炼温度较为适宜。The strain sweep and temperature sweep were adopted to investigate the structure and rheological behavior of CB filled BR/SBR blends.The results showed that the CB tended to distribute in SBR phase,and it does not affect its glass transition temperature.The compatibility is the best when the blend ratio between BR and SBR is 80/20.It is proper to use 60℃ as the mixing temperature for this system.
