Abstract
PURPOSE: An antideteriorant effective in preventing thermal deterioration and flex cracking of a rubber vulcanizate, prepared by mixing a diphenylamine (derivative) with a p-phenylene-diamine derivative.
CONSTITUTION: An antideteriorant for rubber consisting of a composition prepared by mixing 90W30wt% diphenylamine of the formula, wherein R1 and R2 are each H or a lower alkyl, or its derivative (e.g., 4,4'-dimethyldiphenylamine) with 10W70wt% N-phenyl-N'-tolyl-p-phenylenediamine, N-tolyl-N'-alkyl-p-phenylenediamine wherein the alkyl has 3W8C, or N,N'-ditolyl-p-phenylenediamine. This composition shows excellent effects of preventing thermal deterioration and flex cracking of rubber, does not adversely affect vulcanization, does not cause scorching of a rubber formulation during storage and makes it possible to work safely during processing.
