Problems solved by technology

However, the limit temperature of the exhaust gas at the hot end of the turbocharger may be as high as 200°C, and the pulse pressure is large and the frequency is high. Therefore, how to develop a turbocharger hose that is more resistant to high temperature and high pulse, to meet the requirements of the modern automobile industry for the hose at the hot end of the turbocharger Requirements become a major topic

Abstract

The invention discloses ethylene-acrylate rubber resistant to 200 DEG C, low in pressure change and high in pulse. According to the technical scheme, the ethylene-acrylate rubber is prepared from, by weight, 80-120 parts of ethylene-acrylate rubber, 1-3 parts of stearic acid, 1-3 parts of liquid antioxidant, 1.5-4.5 parts of auxiliaries, 50-80 parts of carbon black and 20-40 parts of functional reinforcing agent. The invention has the advantages that the formula of the rubber is optimized, oxygen free radicals are effectively captured, and the free radicals are prevented from damaging the molecular structure of a high polymer and causing degradation of the high polymer, so that the liquid oxidant and the rubber have better compatibility; the heated ceramic micro powder is beneficial to combination of rubber, carbon black and various auxiliaries, the service life of the turbocharging pipe under extremely severe conditions is greatly prolonged, and the safety and practicability of the turbocharging hot end pipe assembly can be improved.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an ethylene-acrylate rubber resistant to 200°C, low pressure change and high pulse. Background technique [0002] With the continuous development of the automobile industry, more and more attention has been paid to environmental protection, and the development of the automobile industry will inevitably bring a large amount of automobile exhaust emissions. The car industry in the automobile industry accounts for about 95%, and the annual sales volume exceeds 10 million. With the development of the car industry, the models of domestic and foreign mainstream brands are all equipped with turbocharging systems, and the temperature and pressure requirements for the hot end of the turbocharging system are getting higher and higher. In the early days, the manual coating of silica gel and fluorine rubber was used. Low efficiency and high cost, the new high temperature resistant ...
