Embodiment

[0072] Based on the components and contents in Table 1 below, samples of engine mount rubber compositions for preventing aging according to the present invention (Examples 1 and 2) and Comparative Examples were produced and their physical properties were compared. The results are listed in Table 2 below.

[0073] [Table 1]

[0074]

[0075]

[0076] Table 1 is a table comparing components and contents of Examples 1 and 2 and Comparative Example according to the present invention.

[0077] Referring to Table 1, samples of an engine mount rubber composition for preventing aging were prepared. More specifically, natural rubber was kneaded for 2 minutes by using an internal mixer, and then carbon black was added, followed by kneading it for 10 minutes. After that, the activator, anti-aging agent, etc. were mixed and kneaded for 2 min to prepare a carbon masterbatch. Sulfur, heat-resistant cross-linking agent and cross-linking accelerator are added to the carbon masterbatc...

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.

Description

[0001] Cross References to Related Applications [0002] Based on 35 U.S.C. §119, this application claims priority to Korean Patent Application No. 10-2013-0018579 filed with the Korean Intellectual Property Office on February 21, 2013, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to an engine mount rubber composition for preventing aging, and more particularly, to an engine mount rubber composition for preventing aging, which comprises 2-mercaptobenzimidazole (MB), An anti-aging agent composed of a mixture of N-isopropyl-N'-phenyl-p-phenylenediamine (IPPD) and microcrystalline wax (micro wax or microcrystalline wax). The composition prolongs the life of engine mounts by inhibiting the outflow and cohesion of chemical additives on the rubber surface. Background technique [0004] The engines of vehicles such as automobiles and airplanes generate vibration and noise due to various factors...
