PURPOSE: A tire rubber composition is provided to ensure the properties similar to or more than conventional rubber compositions, to maintain antiaging property and antioxidation caused by flection and ozone, and to prevent appearance pollution. CONSTITUTION: A tire rubber composition comprises 100.0 parts by weight of a base rubber and 0.25~4 parts by weight of (N'-isopropyl-N-phenyl-p-phynylenediamine)-(4,4'-bis(alkylamino)diphenylamine) represented by chemical formula(1). The (N'-isopropyl-N-phenyl-p-phynylenediamine)-(4,4'-bis(alkylamino)diphenylamine) of chemical formula(1) is obtained by reacting 3PPD(N'-isopropyl-N-phenyl-pphynylenediamine) and (4,4'-bis(alkylamino)diphenylamine). |
