The present invention discloses a tire tread rubber composition. The tire tread rubber composition according to the present invention comprises silica or carbon black as a reinforcing material to be mixed with raw rubber, and comprises organosilane represented by chemical formula 1 for coupling of the raw rubber with the reinforcing material. Accordingly, the crosslinking density with the reinforcing material filler is increased by the organosilane, the activity of the specific functional group of the reinforcing material is prevented to enhance the dispersibility, thereby enhancing the low fuel efficiency performance and securing the workability and reinforcement.

    본 발명은 타이어트레드 고무조성물을 개시한다. 본 발명에 따르는 타이어트레드 고무조성물은 원료고무에 배합할 보강재로 실리카 또는 카본블랙을 포함하며, 원료고무와 보강재의 커플링을 위하여 <화학식1>에 의한 오가노실란을 포함하는 것을 특징으로 하는데, 이에 의할 때, 오가노실란으로 보강재 필러와의 가교밀도를 증가시키고, 보강재의 특정 작용기의 활성을 방지하여 분산성을 높여서 저연비 성능을 향상시키는 동시에 가공성, 보강성을 확보할 수 있다.
