The present invention relates to a carbon black dispersion / binder that can improve the bonding strength between rubber and carbon black and a carbon black-filled rubber composite for tires manufactured using the same. Specifically, the rubber composition for the tires according to the present invention comprises a carbon black-rubber composite formed by mixing 3-aminopropyl hydrogen sulfate, carbon black, and raw rubber represented by the chemical formula 1. According to the present invention, 3-aminopropyl hydrogen sulfate is applied as a binder for the carbon black and the rubber, which chemically combines the carbon black and rubber, and thus, hysteresis can be dramatically improved while maintaining the advantages of existing carbon black-rubber composites.

    본 발명은 고무와 카본블랙의 결합력을 향상시킬 수 있는 카본블랙 분산/결합제와 이를 이용해 제조한 타이어용 카본블랙 충진 고무 복합체에 관한 것이다. 구체적으로, 본 발명에 따른 타이어용 고무 조성물은 하기 화학식 1로 표시되는 3-Aminopropyl hydrogen sulfate, 카본블랙 및 원료고무를 혼합하여 형성된 카본블랙-고무 복합체를 포함하는 것을 특징으로 한다. [화학식 1] JPEGpat00004.jpg1948 본 발명에 의하면 3-Aminopropyl hydrogen sulfate를 카본블랙과 고무의 결합제로 적용함으로써, 카본블랙과 고무를 화학적으로 결합시켜 기존 카본블랙-고무 복합체의 장점을 유지하면서 히스테리시스를 획기적으로 개선할 수 있다.
