Abstract
Thiuram (DPTT, TMTD), thiazole (MBT, MBTS), sulfenamide (CBS, NOBS), and zinc containing thiuram (dithiocarbamate) (ZDBC) type accelerators were added into silica and carbon black filled natural rubber (NR) compounds. Their effects on vulcanization time and rate were compared. The vulcanization rate of thiuram type accelerator added compounds showed the fastest rate, followed by thiazole and sulfenamide types. Silica filled natural rubber (NR) compounds showed a slower vulcanization time (ts2, t10, t90) and lower cure rate index (CRI) than carbon black filled ones upon each accelerator.

화학적 구조가 다른 thiuram계 TMTD(tetramethyl thiuram disulfide), DPTT(dipenta-methylene thiuram tetrasulfide), thiazole계 MBT(2-mercapto benzothiazole), MBTS(2,2-dithiobis(benzo-thiazole)), sulfenamide계 CBS (n-cyclohexyl benzothiazyl-2-sulfenamide), NOBS(n-oxydiethylene benzo-thiazyl-2-sulfenamide), 아연이 포함된 thiuram계 ZDBC(zinc di-n-butyl-dithiocarbamate)를 사용하여 각각의 촉진제가 실리카와 카본블랙으로 충전된 천연고무 복합소재의 가황 속도 및 가황 지수에 미치는 영향을 비교 평가하였다. 양 시스템에서 가황 속도는 thiuram계, thiazole계, sulfenamide계의 순서로 동일한 경향을 보였다. 각 촉진제에 대하여 실리카 컴파운드는 카본블랙 컴파운드에 비해 ts2, t10, t90에 도달하는 시간이 느리게 나타났으며 느린 가황 지수(CRI)를 나타내었다.

Keywords: accelerators; carbon black; silica; natural rubber; vulcanization time; rate.
