国产官能化溶聚丁苯橡胶BF2055M混炼胶性能研究OA北大核心CSTPCD

Functionalized solution polymerized styrene butadiene rubber(SSBR)has been widely used in the field of green high-performance tires with numerous grades.The comprehensive performance of three imported functionalized SSBR that are more commonly used in the domestic tire industry was compared with domestic functionalized SSBR BF2055M.The experimental results show that compared with imported SSBR,SSBR BF2055M has good silica dispersibility,good affinity with silica,good processing safety,and fast vulcanization rate.The vulcanized rubber has high tensile stress,good resilience,high tensile strength,and low compression temperature rise.It has a better balance of high wet skid resistance and low rolling resistance performance,which can provide better driving safety and fuel efficiency for tires and is suitable for all season tires used on urban roads.It is recommended to compound SSBR with natural rubber in the development of tire tread formula to improve the wear resistance of vulcanized rubber.
