Ethylene propylene diene monomer composition and application thereof

Abstract

The invention relates to an ethylene propylene diene monomer composition and an application of the composition. The ethylene propylene diene monomer composition comprises rough ethylene propylene diene monomer, zinc oxide, polyethylene glycol, stearic acid, anti-aging agent RD, coumarone, fast-extruded carbon black, functional filler Create-E2, paroline, an accelerant BZ (benzodiazepine), accelerant TMTD (tetramethyl thiuram disulfide), accelerant DPTT (dipentamethylenethiuram hexasulfide), and vulcanizing agent sulphur; and the ethylene propylene diene monomer provided by the invention is used for automobile hoses, has the characteristics of stable process and property, long service life, and the like and can satisfy the current operating requirements completely.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an ethylene propylene diene monomer rubber composition for heat aging resistance and electrochemical corrosion resistance and its application. Background technique [0002] With the rapid development of the automobile industry, automobiles are developing in the direction of light weight, high efficiency and economy, which leads to the structure of automobile body and engine becoming more and more compact, and the performance of the whole vehicle is also continuously improved, so the work of automobile cooling system The temperature is rising, and at the same time, due to the potential difference between the engine and the surrounding components during the operation of the car, the inner wall of the rubber hose will be cracked under the long-term electrochemical corrosion, which seriously affects the service life of the rubber hose. The EPDM rubber composition used for heat aging r...
