To vulcanize rubber compounds sulfur is mainly used. In order to increase the cure rate, various types of accelerators are developed. Most of the researches were implemented based on the vulcanization of carbon black filled compounds. However, there are a few studies on the effect of cure accelerators for the silica filled compounds. Silica filler shows better dynamic viscoelastic properties than carbon black filler in the tire tread rubber compounds. So, it is essential to use silica as filler in order to manufacture fuel efficiency tires. Silica and carbon black may be expected that the effect is different on the vulcanization due to the differences in the structure and surface properties. In this study, vulcanization accelerators such as CBS, TBBS, DCBS, MBT, MBTS, ZMBT, TMTD, DPG, ZDEC, ZDBC, ZBEC, and HMTA were evaluated for the solution-styrene-butadiene rubber (SSBR)/silica compounds. Using accelerators having a different chemical structure was compared the effects on the vulcanization characteristics and mechanical properties of the SSBR/silica compounds. Cure rate, maximum torque and delta torque of thiazoles, thiurams were higher than those of sulfenamides on vulcanized SSBR/silica composites. Vulcanizates cured by ultra-fast accelerators showed higher moduli at 100% and 300% elongation compared to the vulcanizates cured by other accelerators on the SSBR/silica composites. On the contrary, scorch time of SSBR/silica vulcanizates cured with thiazoles, thiurams and dithiocarbamates were faster than SSBR/silica vulcanizates cured with sulfenamides. These results will be provided a guideline for selection of the type of accelerator and determination of accelerator/sulfur ratio in silica-filled tire compounds
