| 中文摘要: |
| 对高反式-1，4-聚异戊二烯（TPI）/高乙烯基聚丁二烯橡胶（HVBR）/NR共混物的综合物理性能和动态力学性能进行研究。结果表明，在TPI/HVBR/NR共混物中，NR用量为70份，HVBR用量为10～20份，可使胶料具有较低的滚动阻力和生热，且胶料的抗湿滑性明显改善。当HVBR用量为20份时，表征胶料抗湿滑性能的0 ℃时的tanδ值提高42.2%，而表征滚动阻力和生热的60和80 ℃时的tanδ值进一步降低；NR用量为70～50份、TPI用量为10～25份和HVBR用量为20～35份的TPI/HVBR/NR共混物不仅具有较好的综合物理性能，而且具有较低滚动阻力和较高抗湿滑性，是一种较为理想的胎面胶配合。 |
| 英文摘要: |
| The comprehensive physical properties and dynamic mechanical properties of TPI/HVBR/NR （trans-1，4-polyisoprene/high vinyl polybutadiene）blends were investigated.The results showed thatthe lower rolling resistance and heat build-up were obtained and the wet traction improved significantly when 70 phr of NR and 10～20 phr of HVBR were used in the TPI/HVBR/NR blend；tanδat 0 ℃ of the blend increased by 42.2% and tanδat 60 and 80 ℃ decreased somewhat when 20 phr of HVBR were used；and the TPI/HVBR/NR blend with 70～50 phr of NR，10～25 phr of TPI and 20～35 phr of HVBR possessed not only better comprehensive physical properties，but also lower rolling resistance and higher wettraction，and was an ideal tread compound. |
