PURPOSE: A tire tread rubber composition is provided to maximize compatibility with a base rubber and dispersibility by comprising organo kenyaite and to improve abrasion resistance. CONSTITUTION: A tire tread rubber composition comprises 100.0 parts by weight of a base rubber, 3~30 parts by weight of organo kenyaite, and 0.5~8 parts by weight of coupling agent as a dispersing agent of organo kenyaite. The organo kenyaite is obtained by dispersing kenyaite in an ethanol solution in which an organic modifier including an amine group and a silyl binder are mixed, inducing a silyl bond to a kenyaite interlayer by evaporating the ethanol solution, and bonding an amine functional group. |
