| 中文摘要: |
| 采用改性高岭土/炭黑补强胶料，从偶联剂种类、用量和改性方法3个方面探讨高岭土的改性效果及改性高岭土对胶料性能的影响。结果表明：硅烷偶联剂KH550改性高岭土适用于胶料补强，高岭土表面的羟基与偶联剂反应形成烷基化合物，使改性高岭土能够对胶料起到良好的补强作用；与干法改性相比，球磨湿法改性可明显细化高岭土粉体；改性高岭土的引入降低了炭黑对胶料生热的影响，提高了胶料的拉伸强度和拉断伸长率，降低了滚动阻力。 |
| 英文摘要: |
| In this work，the modification of kaolin by couple agents and the influence of the modified
kaolin on the properties of carbon black filled compound were investigated from three aspects: type of
coupling agent，amount of coupling agent，and modification method. The results showed that the modified
kaolin with silane coupling agent KH550 was suitable for compound reinforcement. The coupling agent
reacted with the surface hydroxyl group of the kaolin to form alkyl compounds，and the modified kaolin could
provide good reinforcing effect for the compound. Compared with dry modification method，wet ball milling
modification could refine the kaolin powders effectively. The addition of the modified kaolin reduced the
effect of carbon black on the heat build-up of the compound. Moreover，the tensile strength and elongation at
break of the compound were enhanced，and the rolling resistance was reduced. |
