The present invention relates to a rubber composition for low heat under treads. More specifically, the present invention relates to a rubber composition for under treads. To this end, carbon black, whose dibutyl phthalate (DBP) oil absorption rate, specific surface area for nitrogen (N_2) adsorption, and average particle diameter are controlled within a specific range, is added in raw rubber at a specific composition ratio, thereby maintaining or enhancing excellent mechanical properties while improving mileage through reduction of heat emission in rubber.
본 발명은 저발열 언더트레드용 고무 조성물에 관한 것으로, 원료고무에 디부틸프탈레이트 (DBP) 흡유량, 질소(N) 흡착 비표면적 및 평균입경이 특정 범위로 조절된 카본블랙을 소정의 조성비로 포함시켜, 고무의 발열 저감을 통한 연비성능의 개선하면서도 기계적 물성이 우수하게 유지 또는 향상되는 언더트레드용 고무 조성물에 관한 것이다.
