Abstract
Disclosed is an engine mount rubber composition for aging prevention, and more specifically engine mount rubber composition for aging prevention comprising an anti-aging agent, which consists of: a material participating in chemical bonding in the rubber and inhibiting flowing out of chemical additives such as 2-mercaptobenzimidazole; a material forming a dispersible aging preventing layer on the rubber surface and inhibiting cohesion of the flowed out chemical additives such as N-isopropyl-N′-phenyl-paraphenylenediamine; and a micro wax. The engine mount rubber composition of the present invention has an effect of prolonging life of the engine mount by inhibiting flowing out and cohesion of chemical additives on the rubber surface.
