초록

실리카가 충전된 천연고무 복합소재 내에서 실란 함량의 증가가 실리카간의 구조 발달 상수 (${\alpha}_F$)에 미치는 영향을 비교하였다. 동일한 실리카양 (10, 20, 30, 40 phr)에서 실란의 함량 (2, 4, 6, 8, 10, 12%)이 증가할수록 ${\alpha}_F$값이 증가하는 경향이 나타났다. 이는 실란내 존재하는 황이 가교에 참여하였기 때문인 것으로 판단된다. 또한 실란 함량이 같은 조건에서 실리카양이 증가할수록 ${\alpha}_F$값이 증가하였는데 이는 실리카 간 상호관계가 증가하였기 때문인 것으로 판단된다.

The silica-silica interaction parameter (${\alpha}_F$) of the silane treated silica filled natural rubber (NR) compound was investigated. As silane (TESPT) concentration increased from 2 to 12% (2, 4, 6, 8, 10, 12%), the ${\alpha}_F$ value increased at the same silica concentration (10, 20, 30, and 40 phr). It seemed the sulfur atoms in TESPT acted as a crosslinking agent in the compound. As silica concentration increased from 10 to 40 phr, the ${\alpha}_F$ value increased at the same silane concentration due to increased silica-silica interaction.
