| 摘 要： | 以低共熔溶剂（DES）为白炭黑的改性剂，通过与双3-（三乙氧基硅）丙基]四硫化物（TESPT）并用进行原位反应改善白炭黑在丁苯橡胶中的分散性，研究了不同种类DES对白炭黑/丁苯橡胶复合材料硫化特性、加工性能、物理机械性能和微观形貌的影响。结果表明，氯化胆碱/尿素与TESPT并用可以明显改善白炭黑在丁苯橡胶中的分散性，使Payne效应减弱，并提升白炭黑/丁苯橡胶硫化胶的力学性能和压缩疲劳性能；氯化胆碱/乙二酸与TESPT并用对提高白炭黑与丁苯橡胶界面结合力效果显著，所得白炭黑/丁苯橡胶复合材料的耐磨性能优异；而当DES用量较大时改性效果不佳。

| Abstract: | With deep eutectic solvent (DES) as the modifier of silica, the dispersity of silica in styrene butadiene rubber (SBR) was improved by in-situ reaction under the synergistic effect of DES and bis(3-triethoxysilyl-propyl)-tetrasulfide (TESPT). The effects of different types of DES on curing characte-ristics, processing properties, physico-mechanical properties, and micromorphology of SBR/silica composites were researched. The results showed that choline chloride/urea in combination with TESPT could significantly improve the dispersity of silica in SBR matrix and weaken the Payne effect, so the mechanical properties and compression fatigue property of SBR/silica vulcanizates increased. Meanwhile, choline chloride/oxalic acid in combination with TESPT showed outstanding performance in impro-ving the interface adhesion between silica and SBR resulting in excellent wear resistance of SBR/silica composites. However, when the amount of DES was overdosed, the modification effect became worse. |
