The present invention discloses a tire cap tread rubber composition comprising a porous reinforcing filler. According to the present invention, the tire cap tread rubber composition comprising the porous reinforcing filler contains a mixture of liquid rubber and a porous silica powder coated with an organosilane polyol according to chemical formula 1, and raw material rubber. Accordingly, the tire cap tread rubber composition improves processability and mixing property, has no need to apply high temperature heat during blending, and has reduced total weight of tread rubber, thereby improving a fuel-efficiency property.

    본 발명은 다공성 보강 충전제를 포함하는 타이어 캡트레드 고무 조성물을 개시한다. 본 발명에 따르는 다공성 보강 충전제를 포함하는 타이어 캡트레드 고무 조성물은 화학식 1에 의한 유기실란폴리올에 의해 코팅된 다공성 실리카 분말과 액상고무와의 혼합물과 원료고무를 포함하는 특징이 있는데, 이에 의할 때 트레드 고무와 가공성과 혼합성을 개선시키고, 배합시 높은 온도의 열을 가할 필요가 없어 에너지 효율이 우수하며, 트레드 고무 전체의 중량을 감소시킬 수 있어 연비 특성을 향상시킬 수 있다.
