摘要

通过羰基的硅氢化反应实现液体聚丁二烯橡胶的精准封端，合成了三甲氧基硅烷封端(TMSLPB)与三乙氧基硅烷封端(TESLPB)的液体聚丁二烯橡胶. 研究了上述硅烷封端液体橡胶(SLPBs)作为二氧化硅填充的丁苯橡胶/顺丁橡胶(SBR/BR)的界面改性剂对橡胶复合材料性能的影响. 结果表明，SLPBs能显著减弱二氧化硅的团聚现象，改善填料分散性，增强橡胶复合材料性能. 此外，3份TESLPB作为界面改性剂时SBR/BR橡胶复合材料的力学性能最优异，60 ℃时损耗因子值最低，磨耗损失最小.

Abstract

Precise capping of liquid polybutadiene was achieved by silica hydrogenation reaction

and trimethoxysilane terminated (TMSLPB) and triethoxysilane terminated (TESLPB) liquid polybutadiene rubbers were successfully synthesised. The effects of the above liquid rubbers as interfacial modifiers of silica-filled styrene-butadiene rubber/butadiene rubber (SBR/BR) on the properties of the composites were investigated. The results showed that TMSLPB and TESLPB could significantly attenuate the agglomeration phenomenon of silica

improve the dispersion of filler

and enhance the rubber composite properties. In addition

the mechanical properties of SBR/BR rubber composites were the best when 3 phr of TESLPB was used as plasticiser

with the lowest loss factor value at 60 ℃ and the smallest abrasion loss.
