PURPOSE: A rubber composition for tire tread is provided to derive a quick initial grip performance of a tire tread part when traveling with high speed, and to improve durability and abrasion resistance of tire while maintaining a rear grip performance. CONSTITUTION: A rubber composition for tire tread is provided to comprise surface-modified graphene. The rubber composition comprises 100.0 parts by weight of raw rubber, and 0.1-50.0 parts by weight of surface-treated graphene, and additionally comprises 20-30 parts by weight of carbon black. The rubber composition for tire tread comprises a master batch which comprises the surface-treated graphene, raw rubber and carbon black. The surface-treated graphene is modified by an organic compound comprising a carboxyl group. |
