Abstract

Various types of accelerators, thiuram (TMTD, DPTT), thiazole (MBT, MBTS), and sulfenamide (CBS, NOBS) are added into a silica filled natural rubber compound. Their effects on vulcanization and mechanical properties are investigated. TMTD showed the fastest vulcanization rate, the higer maximum torque ($T_{max}$), and the excellent mechanical properties (300% modulus, tensile strength, elongation). MBT and MBTS showed an intermediate vulcanization rate between thiuram and sulfenamide type and added ones, and also showed the lower $T_{max}$ and mechanical properties compared to that of other compounds. Finally, NOBS showed the slowest vulcanization rate and the lower mechanical property but the moderate $T_{max}$.

본 연구에서는 화학적 구조가 다른 thiuram계 tetramethyl thiuram disulfide (TMTD), dipenta methylene thiuram tertasulfied (DPTT), thiazole계 2-mercapto benzothiazole (MBT), 2,2'-dithiobisbenzothiazole (MBTS), sulfenamide계 n-cyclohexyl benzothiazyl-2-sulfenamide (CBS), n-oxydiethylene benzo-thiazyl-2-sulfenamide (NOBS)를 사용하여 각각의 촉진제가 실리카가 충진된 천연고무의 가황 특성 및 기계적 물성에 미치는 영향을 비교 평가하였다. TMTD는 상대적으로 빠른 가류 속도와 높은 최대 토크값($T_{max}$), 우수한 기계적 물성을 보였고 MBT, MBTS는 상대적으로 중간 정도의 가황 시간과 $T_{max}$, 기계적 물성을 보였다. 마지막으로 NOBS는 느린 가황 시간과 낮은 기계적 물성을 나타낸 반면 중간 값의 $T_{max}$를 나타냈다.
