Abstract

본 발명은 타이어의 내마모성 및 연비성능의 하락없이 웰스키드(wet skid)성능을 향상시킨 타이어 트레드용 고무조성물에 관한 것이다.The present invention relates to a rubber composition for a tire tread which improves the wet skid performance without deteriorating the abrasion resistance and fuel consumption performance of the tire.

본 발명의 고무조성물은 스티렌 함량이 23.5중량% 이상인 하이스티렌 고무 30∼70중량부와 유리전이온도가 -50℃ 이하이고 오일함량이 20∼40중량%인 스틸렌부타디엔 고무 30∼70중량부로 이루어진 고무성분 100중량부에 대하여 카본블랙 75∼100중량부, 부틸페놀-피-티-아세틸렌수지 2∼15중량부, 가류제 2∼3중량부, 촉진제 I 1∼2중량부 및/또는 촉진제 Ⅱ 0.1∼0.5중량부를 함유하는 것을 특징으로 한다.The rubber composition of the present invention comprises 30 to 70 parts by weight of a high styrene rubber having a styrene content of 23.5% by weight or more, 30 to 70 parts by weight of a styrene butadiene rubber having a glass transition temperature of -50 캜 or less and an oil content of 20 to 40% 1 to 2 parts by weight of accelerators I and / or accelerator II < RTI ID = 0.0 > 0.1 < / RTI > To 0.5 parts by weight.
