摘要
研究国产稀土异戊橡胶(IR)与天然橡胶(NR)并用对胶料性能的影响。结果表明:随着IR用量的增大,NR/IR胶料的门尼焦烧时间和t90逐渐延长,MH-ML逐渐减小;炭黑分散性不变,IR与NR的相容性良好;硫化胶的邵尔A型硬度和撕裂强度逐渐减小,300%定伸应力和回弹值呈下降趋势,压缩生热降低,耐屈挠性能提高;当NR/IR并用比小于50/50时,胶料的综合性能较好。
The properties of NR/domestic IR blend were investigated. The resu compatibility between IR and NR was good. As the addition level of IR increased, time and t^0 of NR/IR compound extended gradually,M.--ML decreased gradually of carbon black unchanged. The Shore A hardness and tear strength of vulcanizate ly,the modulus at 300% elongation and resilience tended to decrease,the eompre decreased,and the flexing resistance was improved. When the NR/IR blend ratio w the comprehensive properties were better.
