Abstract

Zinc ion containing thiuram type accelerator zinc dibutyldithiocarbamate (ZDBC) was compared to other thiuram type accelerators (tetramethylthiuram disulfide (TMTD) and dipentamethylenethiuram tetrasulfide (DPTT)) in silica filled natural rubber (NR) compound upon vulcanization and mechanical properties (modulus, tensile strength, and elongation %). ZDBC added compound showed the fastest cure time (t10) and the highest reinforcement index (R.I.) among them and showed a marching behavior. The mechanism was reviewed and a new mechanism was proposed.

아연이온이 포함된 thiuram 구조를 가진 zinc dibutyldithiocarbamate(ZDBC)와 아연이온을 포함하고 있지 않은 thiuram계 촉진제인 tetramethylthiuram disulfide(TMTD), dipentamethylenethiuram tetrasulfide(DPTT)를 실리카가 충전된 천연고무에 첨가하여 가황특성 및 기계적 물성(모듈러스, 인장강도, 신장률)에 미치는 영향을 비교 평가하였다. ZDBC는 가장 빠른 반응개시시간(t10)과 높은 보강성(R.I.), 그리고 marching 거동을 보였다. 메커니즘을 고찰하고 제시하였다.
