中文摘要:
      采用天然橡胶（NR）中非胶组分对炭黑改性不同时间（0.1，5，20和60 min），考察NR中非胶组分对炭黑表面能的影响，并制备炭黑/NR复合材料，考察非胶组分对炭黑补强性能的影响。结果表明：改性0.1 min，炭黑表面能的色散组分显著下降；非胶组分能够延缓炭黑/NR硫化胶的老化速率，改善硫化胶的动态力学性能，降低生热，但导致耐磨性能下降。
英文摘要:
      Non-rubber components from natural rubber（NR） were used to modify carbon black for different durations（0.1，5，20 and 60 min）.The influence of the non-rubber components on the surface energy of carbon black was investigated，and carbon black/NR composites were simultaneously prepared to examine the effect of the non-rubber components on the reinforcing performance of carbon black.The results showed that even after 0.1 min modification，the dispersive component of the carbon black’s surface energy decreased significantly.The non-rubber components were able to delay the aging rate of the carbon black/NR vulcanizate，improved the dynamic mechanical property and reduced heat build-up，but made the wear resistance to descend.
