Abstract

본 발명은 충전제로서 실리카 및 카본블랙을 적정비율로 혼합 사용함으로써, 저연비 타이어에 유요할 뿐만 아니라 우수한 반발탄성 및 발열특성을 갖는 실리카를 함유한 타이어 트레드용 고무조성물에 관한 것이다.The present invention relates to a rubber composition for tire treads containing silica, which is not only useful for low fuel consumption tires but also has excellent rebound elasticity and exothermic properties by mixing silica and carbon black at an appropriate ratio as a filler.

본 발명은 천연고무와 합성고무로 이루어진 혼합고무 100PHR에 대하여 실리카를 20-30OPHa 함유하고, 카본블랙과 실리카로 이루어진 총 충전제 함량이 40∼60PHR 범위에 있는 것을 특징으로 한다.The present invention is characterized by containing 20-30 OPHa of silica with respect to 100 PHR of mixed rubber composed of natural rubber and synthetic rubber, and having a total filler content of carbon black and silica in the range of 40 to 60 PHR.
