中文摘要:
      研究了NR/BR/NBR并用胶的结构与性能。透射电子显微镜分析显示，随着NBR用量的增大，炭黑的分散趋于均匀；NR/BR/NBR并用胶出现两个玻璃化温度，在0 ℃时的tanδ值增幅较大，而在65和80 ℃时的tanδ值变化不大；并用胶物理性能变化不大。通过调节NBR用量可获得抗湿滑性能较好、滚动阻力和生热小的胎面胶。
英文摘要:
      The structure and properties of NR/BR/NBR blend were investigated.It was found through the analysis by TEM that as the proportion of NBR increased，the distribution of carbon black tended to more even；two glass transition temperatures existed in the blend；the tanδat 0 ℃ increased greatly and the tanδat 65 and 80 ℃ decreased at first and then increased in a small range；and the physical properties of blend changed little.A new type of tread compound based on NR/BR/NBR with good wet traction，low rolling resistance and low heat build-up could be obtained by adjusting the proportion of NBR in the blend.
