中文摘要: |
以1-丁基-3-甲基咪唑六氟磷酸盐(Bmim.PF6)离子液对白炭黑进行改性,采用乳液共沉法制备改性白炭黑/SBR复合材料,并对其硫化特性、物理性能和微观结构进行研究。结果表明:Bmim.P6与白炭黑之间的相互作用为氢键作用;与未改性白炭黑/SBR复合材料相比,改性白炭黑/SBR复合材料的交联密度增大,白炭黑在橡胶基体中的分散性得到改善,拉伸强度、撕裂强度和耐磨性能均明显提高。 |
英文摘要: |
Using 1-butyl-3-methyl-imiazolium hexafluorophosphate(Bmim.PF6) modified silica,the modified silica/SBR composites were prepared by latex co-coagulation method,and the curing behavior,physical properties and microstructure of the composites were investigated.The results showed that,the interaction between Bmim.PF6 and silica resulted from hydrogen bond;compared with unmodified silica/SBR composites,modified silica/SBR composites possessed higher crosslink density,and the dispersion of silica in rubber matrix was improved,while the tensile strength,tear strength and wear resistance were increased. |
