【摘要】 采用傅立叶变换红外光谱 (FTIR)分析了溶聚丁苯橡胶 (S SBR)S SBR2 30 5、BunaSL2 5 1及乳聚丁苯橡胶E SBR15 0 0 3种SBR的链化学结构 ,采用定负荷压缩生热、动态力学谱 (DMA)等方法研究了 3种SBR对NR/SBR并用胶耐磨性、生热、滚动阻力及抗湿滑性的影响。结果表明 ,S SBR对于调节NR/SBR并用胶各方面性能具有比较突出的优越性 ,可以实现NR/SBR并用胶的耐磨性、抗湿滑性和低滚动阻力三者的平衡更多还原

【Abstract】 The chain structures of S SBR2305,Buna SL25 1 and E SBR1500 were analysed by FTIR,and the influences of these three SBRs on the wear resistance,heat build up,rolling resistance and wet traction of NR/SBR blend were investigated by the compression heat build up test with constant load,DMA etc..The results showed that the wear resistance,wet traction and rolling resistance of NR/SBR could be well balanced by using S SBR.更多还原
