中文摘要:
      将端基改性溶聚丁苯橡胶（SSBR）与顺丁橡胶（BR）并用，采用白炭黑作主要补强剂，并配合偶联剂Si69，研究硅烷化反应对胶料性能的影响。结果表明：与未进行硅烷化反应的胶料相比，进行硅烷化反应的混炼胶门尼粘度降低，焦烧时间缩短，硫化速度明显加快；进行硅烷化反应的硫化胶定伸应力和回弹值明显增大，生热和滚动阻力降低，抗湿滑性能提高。硅烷化反应可有效提高端基改性SSBR/BR并用胶性能，特别是动态力学性能。
英文摘要:
      In this study，the effect of silylation reaction on the properties of chain-end modified SSBR/BR blends with silica as reinforcing filler and silane coupling agent Si69 was studied.The experimental testing results showed that compared with the blends without silylation reaction，the Mooney viscosity of the silylation modified blends was reduced，scorch time was shortened，curing rate increased，the tensile modulus and resilience of the vulcanizates increased significantly，the dynamic heat build-up and rolling resistance were reduced，and the wet skid resistance was improved.It was concluded that the silylation reaction could effectively improve the properties of chain-end modified SSBR/BR blends，particularly the dynamic properties.
