聚丁二烯橡胶的性能研究

研究不同品种聚丁二烯橡胶的各项性能。结果表明，聚丁二烯橡胶的焦烧安全性较好；中乙烯基聚丁二烯橡胶拉伸强度和撕裂强度较大，耐热空气老化性能和抗湿滑性能较好；BR耐磨性能、耐屈挠性能和动态力学性能较好，适合用于轮胎胎面胶。;The properties of polybutadiene rubbers were studied.The results showed that the scorch safety of polybutadiene rubbers was good；the tensile strength，tear strength，thermal aging property and wet traction of MVBR were better；generally，the wear resistance，flexing resistance and dynamic property of BR were excellent，and BR was suitable for tread compound application
