支化多酚羟基氢化丁腈橡胶/氟橡胶反应型并用胶的制备与性能研究

制备支化多酚羟基氢化丁腈橡胶（PHHNBR）/氟橡胶（FKM）反应型并用胶，并对其性能进行研究。结果表明：PHHNBR具有支化多酚羟基结构，PHHNBR/FKM反应型并用胶可以实现自身的硫化；FKM与PHHNBR相容性良好，并用胶的拉伸强度明显高于FKM硫化胶，撕裂强度相当，玻璃化温度明显降低，耐低温性能改善。;A branched polyphenol hydroxy HNBR（PHHNBR）/FKM reactive blend was prepared，and its properties were investigated.The results showed that，the PHHNBR has the structure of branched polyphenol hydroxy，and the PHHNBR/FKM reactive blends could be self-vulcanized.The compatibility between FKM and PHHNBR was good，and comparing to FKM vulcanizates，the tensile strength of blend was higher，the tear strength was similar，the glass transition temperature was lower，and the low temperature resistance was better
