中文摘要：
利用N-甲基咪唑与巯基琥珀酸的中和反应制备一种新型双离子型功能离子液体双（1-甲基咪唑）巯基琥珀酸盐（BMimMS），对其结构进行表征；以BMimMS作为界面改性剂对白炭黑／丁苯橡胶（SBR）复合材料进行改性，并对其填料网络、硫化特性、物理性能和微观形态进行研究。结果表明：BMimMS的阳离子与硅-氧键及阴离子与硅烷醇之间存在氢键作用；随着BMimMS用量的增大，白炭黑／SBR复合材料的交联密度增大，但白炭黑的分散并未明显改善。BMimMS能有效增强白炭黑与SBR间的相互作用，提高白炭黑／SBR复合材料的物理性能和低温区（-20～0℃）的损耗因子，使复合材料的抗湿滑性能提高。
英文摘要：
A novel Gemini ionic liquid, bis （1-methylimidazolium） mercaptosuccinate（BMimMS）, was synthesized by neutralization of N-methyl imidazole and mercaptosuccinic acid, and the structure of BMimMS was characterized. BMimMS was used as the interfacial modifier for silica/SBR composites,and the filler network, curing behavior, physical properties and morphology of the composite were investigated. The results showed that,the cation and anion of BMimMS formed hydrogen bond with siloxane and silanol of silica,respectively. The crosslink density of silica/SBR composites was increased as the addition level of BMimMS increased, but the dispersion of silica was not obviously iraproved. BMimMS could effectively strengthen the silica-SBR interracial interaction, and the physical properties and loss factor in low temperature region（- 20-0 ℃） were improved by BMimMS, resulting in improved wet skid resistance.
