摘要
研究了铁系乙烯基丁二烯橡胶(FVBR)与天然橡胶(NR)以50/50(质量比)共混硫化胶的物理机械性能和黏弹特性,并与溶聚丁苯橡胶(SSBR)与NR共混胶进行了对比。结果表明,FVBR与NR有良好的相容性,共混胶只存在1个玻璃化转变温度。FVBR/NR的混炼行为良好,但必需添加操作油,否则难以获得理想的硫化胶性能。FVBR/NR与SSBR/NR相似,不仅具有良好的拉伸和撕裂性能,而且具有高抗湿滑性;其生热和滚动阻力以及热老化性能优于后者,但耐磨性略逊于SSBR/NR。
The mechanical properties and viscous elasticity were researched of blends of vinyl polybutadiene by iron catalyst(FVBR)/natural rubber(NR) compared with solution polymerized styrene-butadiene rubber(SSBR)/NR blends.The results showed that there was a good compatibility between FVBR or SSBR and NR,as there was only one glass transition temperature in either blends.FVBR/NR blends had the same good mixing behavior as SSBR/NR,but the proper amount of extended oil should be added to obtain the better properties...
