摘　　要：研究了NR/BR为70/30(质量比 )时普通、半有效和有效3种硫化体系共混物的拉伸疲劳寿命和力学性能。从生热、连续和间歇应力弛豫等行为上讨论了3种硫化体系共混物的疲劳断裂机理 ,并给出了各体系共混物疲劳断裂特征参数 β 和C0。The fatigue failure and mechanical properties of conventional,semi-efficient and efficient curing systems of NR/BR(70/30) blend were studied.The molecular chain fatigue failure mechanism of above curing systems was discussed from compression heat build-up,continuous chemical stress relaxation and intermittent chemical stress relaxation.Their failure characteristic parameters β and C0 were derived.
