| 中文摘要: |
| 制备芳纶纳米纤维（ANFs）预分散体，研究ANFs用量对溶聚丁苯橡胶（SSBR）胶料性能的影响。结果表明：随
着ANFs用量的增大，SSBR混炼胶的t10和t90无明显变化，FL、储能模量和损耗模量增大，Payne效应增强；SSBR硫化胶的
邵尔A型硬度、100%定伸应力和撕裂强度增大，拉伸强度先减小后增大，损耗因子（tanδ）最大值减小。ANFs用量为4份
的SSBR硫化胶0 ℃时的tanδ最大，抗湿滑性能最好。 |
| 英文摘要: |
| The solution polymerized styrene butadiene rubber （SSBR） compound was prepared by
adding the dispersion of the aramid nanofibers（ANFs），and the effect of the ANFs amount on the properties
of the SSBR compounds was studied. The results showed that，with the increase of the ANFs amount，the
t10 and t90 of the SSBR compound did not change significantly，the FL，storage modulus and loss modulus
increased，and the Payne effect was enhanced. Meanwhile，the Shore A hardness，tensile stress at 100%
elongation and tear strength of the SSBR vulcanizates increased，the tensile strength decreased first and then
increased，and the maximum value of loss factor（tanδ） decreased. The SSBR vulcanizate with 4 phr of the
ANFs had the largest tanδ at 0 ℃ and the best wet skid resistance. |
