| 中文摘要: |
| 通过对粘土进行物理和化学改性，可制成橡胶补强剂，其补强效果接近或达到白炭黑水平。在对橡胶制品密度要求不高的情况下以它替代白炭黑，可明显降低成本。研究了偶联剂KH-845-4和KR-38S对高岭土、绢云母的改性效果，结果表明，用偶联剂KH-845-4改性高岭土，其补强效果明显优于KR-38S。而用KR-38S改性绢云母，其补强效果优于KH-845-4。 |
| 英文摘要: |
| A reinforcing agent of rubber has been developed by the physical and chemical modification of clay. The reinforcing effect of said agent is similar to that of silica. The cost is significantly decreased when it is replaced for silica in the rubber product whose density is not so critical. The effects of the coupling agents KH-845-4 and KR-38S on the modification of clay and silk mica have been investigated. The results show that the reinforcing effect of the clay modified with KH-845-4 is much better than that of the clay modified with KR-38S；in contrast，KR-38S is more effective than KH-845-4 for the silk mica. |
