中文摘要:
      研究微晶纤维素/白炭黑复合填料对高乙烯基溶聚丁苯橡胶性能的影响。结果表明：采用微晶纤维素部分等量替代白炭黑，随着微晶纤维素用量的增大，胶料的门尼粘度减小，t10延长，t90缩短，加工性能和硫化速率提高；硫化胶的邵尔A型硬度、300%定伸应力和拉伸强度减小，拉断伸长率增大，耐磨性能下降；当微晶纤维素用量为5份时，硫化胶的撕裂强度最大，抗湿滑性能提高，滚动阻力降低。
英文摘要:
      The effect of microcrystalline cellulose/silica composite filler on the properties of high vinyl SSBR was investigated.Microcrystalline cellulose was used to replace part of the silica in the fil ler system while the total addition level of filler kept the same.The results showed that， as the addition level of microcrystalline cellulose increased，the Mooney viscosity of the compound decreased，t10 was extended，t90 was shortened，the processability was improved and cure rate was enhanced.The Shore A hardness， modulus at 300% elongation and tensile strength of the vulcanizates decreased，the elongation at break increased，and the wear resistance decreased.When the addition level of microcrystalline cellulose was 5 phr，the vulcanizates possessed the best tear strength，high wet skid resistance and low rolling resistance.
