Disclosed is a rubber composition for tire treads. According to the present invention, the rubber composition for tire treads contains raw rubber, silica, and a process aid represented by chemical formula 1, thereby preventing an increase in production costs due to an increase in a processing time and facility alteration upon application of high surface area stiffeners. At the same time, it is possible to make a mixing process easy due to a drop in viscosity, and it is easy to store rubber for a long time by preventing the re-coagulation of the stiffeners. The use of rubber with excellent dispersibility, even as the high surface area stiffener, can improve tensile properties, rotation resistance, wet road braking, and adjustability.

    본 발명은 타이어트레드용 고무조성물을 개시한다. 본 발명에 따르는 타이어트레드용 고무조성물은 원료고무, 실리카 및 화학식 1로 표현되는 공정조제를 포함하는 특징이 있는데 이에 의할 때, 높은 표면적의 보강재 적용에 따른 설비 변경 및 공정시간 증가에 대한 제조비용을 상승을 방지할 수 있고, 동시에 점도 하락에 따른 배합공정을 원할하게 할 수 있으며, 보강재의 재응집 방지로 고무의 장기보관이 용이하며, 높은 표면적의 보강재 임에도 분산성이 우수한 고무의 사용으로 인장특성, 회전저항, 젖은 노면 제동성, 조정성을 향상시킬 수 있다.
