| 中文摘要: |
| 与炭黑N330对比，研究白炭黑比表面积（白炭黑HPS80GR、白炭黑1125MP、白炭黑1165MP和白炭黑200MP比表面积依次增大）对雪地轮胎胎面胶性能的影响。结果表明：随着白炭黑比表面积的增大，胶料的FL，Fmax和Fmax－FL增大，填充白炭黑200MP的胶料的门尼粘度、FL、Fmax和Fmax－FL最大，填充白炭黑1165MP的胶料的t90最长，填充白炭黑HPS80GR的胶料的Payne效应最小，白炭黑HPS80GR在橡胶基体中的分散性最好；硫化胶的拉伸强度随着白炭黑比表面积的增大而增大；填充白炭黑HPS80GR的硫化胶60 ℃时的tanδ最小，其滚动阻力最小；在10和15 ℃下填充白炭黑200MP的硫化胶的摩擦因数最大，抗湿滑性能最好，在－5，－10和15 ℃下填充白炭黑HPS80GR的硫化胶的摩擦因数最大，抗冰滑性能最好。 |
| 英文摘要: |
| Compared with carbon black N330，the effect of specific surface areas of silica （specific surface area of silica HPS80GR，silica 1125MP，silica 1165MP and silica 200MP increasing） on sequentially the properties of tread compound of snow tire was studied.The results showed that with the increase of specific surface area of silica，the FL，Fmax and Fmax－FL of the compounds increased.The Mooney viscosity，FL，Fmax and Fmax－FL of the compound filled with silica 200MP were the largest，the t90 of the compound filled with silica 1165MP was the longest.The Payne effect of the compound filled with silica HPS80GR was the minimum，indicating the best dispersion of silica HPS80GR in the rubber matrix.With the increase of specific surface area of silica，the tensile strength of the vulcanizates increased.The tanδ at 60 °C of the vulcanizate filled with silica HPS80GR was the smallest，indicating its lowest rolling resistance.At 10 °C and 15 °C，the friction coefficient of the vulcanizate filled with silica 200MP was the minimum，indicating its best wet skid resistance，At －5 °C，－10 °C and 15 °C，the friction coefficient of the vulcanizate filled with silica HPS80GR was maximum，indicating its best ice skid resistance. |
