| 中文摘要: |
| 采用硅烷偶联剂KH550（简称KH550）对氧化石墨烯（GO）和白炭黑同时进行改性，制得KH550-GO-白炭黑复合填料，通过机械共混法制备KH550-GO-白炭黑/丁苯橡胶（SBR）复合材料，并对其性能进行研究。结果表明：KH550将GO与白炭黑通过化学键作用在一起，从而将GO的片层阻隔，促进了填料在SBR中的分散；与白炭黑/SBR复合材料相比，KH550-GO-白炭黑/SBR复合材料的交联密度、邵尔A型硬度和300%定伸应力增大，拉伸强度变化不大，60 ℃时的损耗因子减小，耐磨性能提高。 |
| 英文摘要: |
| The KH550-GO-silica composite filler was prepared by modifying graphene oxide （GO） and silica simultaneously with silane coupling agent KH550（referred to as KH550）.The KH550-GO-silica/styrene-butadiene rubber（SBR） composite was prepared by mechanical blending and its properties were studied.The results show that， KH550 could block the lamellae reconstruction of GO and promote the dispersion of the filler in SBR by forming chemical bonding between GO and silica.Compared with the silica/SBR composite，the crosslinking density，modulus at 300% elongation and shore A hardness of the KH550-GO-silica/SBR composite increased，the tensile strength changed little，the loss factor at 60 ℃ decreased，and the wear resistance was improved. |
