The present invention relates to a rubber composition for winter tire tread. The rubber composition according to the present invention includes 40-60 phr of styrene-butadiene, 40-60 phr of butadiene rubber, 80-120 phr of silica, 8-10 wt% of a silane coupling agent based on the weight of silica, 10-40 phr of sheet-like Mg-silicate, 1-5 phr of zinc oxide, 1-3 phr of stearic acid, 5-40 phr of oil, 0.5-3 phr of sulfur and 0.5-4 phr of an accelerating agent. The rubber composition can improve the braking performance on an iced road surface, while not depending on control of silica addition.
본 발명은 윈터타이어 트레드용 고무 조성물로서 40~60phr의 스티렌-부타디엔, 40~60phr의 부타디엔 고무, 80~120phr의 실리카, 상기 실리카의 중량부에 대한 8~10%의 실란커플링제, 10~40phr의 판상형 MG-실리케이트, 1~5phr의 산화아연, 1~3phr의 스테아린산, 5~40phr의 오일, 0.5~3phr의 유황 및 0.5~4phr의 촉진제를 포함하며, 실리카 첨가량 조절에 의존적이지 않으면서 아이스 노면에서의 제동 성능을 향상시킬 수 있는 방법을 제공할 수 있다.
