发明名称 Rubber composition for tire including a novel anti-oxidant system
摘要 Rubber composition, especially for a tire, based on at least one diene elastomer, a reinforcing filler, a crosslinking system and an antioxidant system, wherein said antioxidant system comprises at least two antioxidants “A” and “B”:;A. an N-alkyl-N′-phenyl-para-phenylenediamine corresponding to the formula (I):; B. a 4,4′,4″-tris(alkylamino)triphenylamine corresponding to the formula (II): ; in which formulae, R1, R2, R3 and R4, which are identical or different, each represent a linear or branched alkyl group having from 1 to 12 carbon atoms or a cycloalkyl group having from 5 to 8 carbon atoms, the A/B weight ratio being between 0.1 and 5.0.

主权项 1. A rubber composition based on at least one diene elastomer, a reinforcing filler, a crosslinking system and an antioxidant system, wherein said antioxidant system comprises at least two antioxidants “A” and “B”: A. an N-alkyl-N′-phenyl-para-phenylenediamine corresponding to the formula (I): B. a 4,4′,4″-tris(1,4-dimethylpentylamino)triphenylamine corresponding to the formula (IV-b): in which formulae, R1 represents a linear or branched alkyl group having from 1 to 12 carbon atoms or a cycloalkyl group having from 5 to 8 carbon atoms, the A/B weight ratio being between 1/10 and 5/1.
