| 中文摘要: |
| 研究了高岭土与炭黑N660、沉淀法白炭黑对天然橡胶（NR）补强性能的差异，并考察了高岭土部分替代炭黑N660在子午线轮胎气密层胶中的应用。结果表明，高岭土对NR的补强作用优于未加偶联剂的沉淀法白炭黑，接近炭黑N660，其中改性高岭土对NR的补强效果优于普通高岭土；采用少量高岭土尤其是改性高岭土等量部分替代炭黑N660，气密层胶料拉伸强度提高，加工性能和其他物理性能变化不大。在橡胶配方中用高岭土部分替代炭黑具有可行性，可降低原材料成本，同时节能降耗。 |
| 英文摘要: |
| The difference of reinforcing properties between kaolin and carbon black N660 and precipitated silica on natural rubber（NR） was studied，and the application of kaolin partially replacing carbon black N660 in inner liner compound of radial tire was investigated.The results showed that the reinforcing effect of kaolin on NR was better than that of precipitation silica without coupling agent，and was close to that of carbon black N660.The reinforcing effect of modified kaolin on NR was better than that of ordinary kaolin. Using a small amount of kaolin，especially modified kaolin，to partly replace carbon black N660 in equal amount，the tensile strength of the inner liner compound was improved，and the processability and other physical properties changed little.It was feasible to partly replace carbon black with kaolin in rubber formulation，which can reduce the cost of raw materials，save energy and reduce consumption. |
