| 中文摘要: |
| 将硅烷偶联剂KH-550改性以及硅烷偶联剂KH-550和K-MEPTS共同改性的白炭黑与氧化石墨烯（GO）复配补强天然橡胶（NR），研究填料与橡胶基体的界面结合方式对胶料性能的影响。结果表明：由硅烷偶联剂KH-550和K-MEPTS共同改性的白炭黑与GO静电组装制得的改性白炭黑-2/GO填充NR得到的胶料具有低的Panye效应和高的结合胶含量，这表明改性白炭黑-2/GO在橡胶基体中的分散性好且与橡胶基体通过共价连接结合紧密；改性白炭黑-2/GO/NR硫化胶滞后损失小，具有低的压缩疲劳温升和高的拉伸强度。 |
| 英文摘要: |
| In this study，silica was modified by silane coupling agent KH550 or co-modified by silane couple agent KH-550 and K-MEPTS，and the modified silica and graphene oxide（GO） were combined to reinforced nature rubber（NR） compound. The effect of interface bonding mode between filler and rubber matrix on the properties of the composites was studied. The results showed that，the NR compound filled with the co-modified silica/GO（refer to as silica-2/GO） which was obtained by electrostatic assembly of co-modified silica and GO had weak Payne effect and high bound rubber content. This indicated that the modified silica-2/GO had good dispersibility in the rubber matrix and was tightly bound to the rubber matrix through covalent bonding. The NR vulcanizate filled with silica-2/GO had a small hysteresis loss，low compression fatigue temperature rise and high tensile strength. |
