Abstract
Present silica dispersing agents are based mainly on fatty acid derivatives of Zn, K and mixture of fatty acid and metallic soaps are used to increase activity. The viscosity of silica filled rubber is lowered by Zn-K soap type silica dispersing agent, thus fluidity of hydrocarbon chains and processibility is improved. Silica dispersing agent should not exert an influence on chracteristics of vulcanization. But scorch and curing time is shortened by Zn-K soap type silica dispersing agent. A newly developed silica dispersing agent, which is a nonmetal type agent, reduced the viscosity and hardness of silica compounding rubber, and the highly increased degree of dispersion of silica is caused by interaction of silica and rubber, Also it did not affect the curing characteristics and scorch stability of silica compounding rubber.

기존 실리카 분산제는 주로 Zn, K의 지방산 유도체이며 지방산과 금속비누의 혼합물은 활성을 높이는데 사용되었다. Zn-K 비누 형태의 실리카 분산제는 탄화수소 사슬의 유동성을 증가시켜 실리카가 함유된 고무 배합물의 점도를 낮추어 주며 그 결과 가공성이 향상된다. 실리카 분산제는 가류 특성에 영향을 미쳐서는 안되는데 Zn-K 비누형태의 분산제는 스코치 및 가류시간을 단축시켰다. 그러나 새로이 개발된 분산제의 경우 금속을 함유하지 않은 non-metal 형태이며 분산제가 실리카와 고무간의 interaction을 유도하여 실리카 분산도를 크게 향상시켰으며 이로 인해 경도 및 점도 저하를 유도하였다. 또한 새로운 분산제는 실리카 고무배합물의 가교특성 및 스코치 안정성에 영향을 미치지 않았다.
