The invention discloses an ethylene-propylene-diene-terpolymer composition for an automobile rubber support ring, and relates to the technical field of automobile retail part manufacturing. The composition comprises ethylene-propylene-diene-terpolymer rubber, activated zinc oxide, stearic acid, polyethylene glycol, anti-aging agents RD, anti-aging agents NBC, carbon black, light calcium carbonate, naphthenic oil, silane coupling agents Si-69, accelerators CZ, accelerators BZ, accelerators TMTD, accelerators DM and sulphur. When the formula of the composition provided by the invention is used for manufacturing the automobile rubber support ring, the problems of poor low-temperature-resistance performance , low brittleness temperature, liability to fracture in winter, lowered material intensity under a high-temperature condition, and poor shock absorption and noise reduction performance for support rings made of plastic materials can be solved.
Description
technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an ethylene-propylene-diene monomer composition for automobile rubber support rings. Background technique [0002] With the rapid development of my country's automobile industry, the requirements for improving the functionality of auto parts and reducing noise in the market are increasing. For this reason, most auto manufacturers pay more and more attention to these market requirements when designing auto parts; There are many parts in the cabin, and these parts include flexible pipes such as some rubber hoses. The vibration noise of the rubber hose is reduced, thereby reducing the overall noise index of the car, and it is also conducive to the fixing of pipelines and assembly points; since these support rings are erected in the engine compartment, these support rings are required to have high temperature resistance. At the same time, the support ring needs t...
