Ethylene-acrylate rubber formula for turbocharging rubber pipes

Abstract

The invention relates to an ethylene-acrylate rubber formula for turbocharging rubber pipes. The ethylene-acrylate rubber formula comprises, by weight, 25-50 parts of ethylene-acrylate rubber HT-OR, 50-75 parts of ethylene-acrylate rubber 5394, 1-3 parts of stearic acid, 1-3 parts of an anti-aging agent 445, 0.5-2 parts of an auxiliary agent 18D, 1-3 parts of an auxiliary agent VAM, 50-80 parts ofcarbon black N550, 10-40 parts of N990 carbon black, 10-30 parts of a plasticizer TP759, 1-4 parts of a cross-linking agent ACT55 and 1-2 parts of a cross-linking agent Diak No.1. A turbocharging pipe assembly prepared according to the formula is excellent in fatigue resistance and aging resistance and high in pulse frequency, the service life of the turbocharging pipe assembly under high-power extreme severe conditions is greatly prolonged, and safety and practicality of the HT-AEM turbocharging pipe assembly are improved.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an ethylene-acrylate rubber formula for turbocharger hoses. Background technique [0002] With the continuous development of the automobile industry, more and more attention is paid to environmental protection, and the development of the automobile industry will inevitably bring a large amount of automobile exhaust emissions. The emission standards of automobile exhaust in my country must reach the Euro 6 standard before 2020. 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...

Problems solved by technology

Like the well-known TL52634 standard in the industry, it puts forward quite strict high-temperature and low-temperature compression set standards for rubber tubes, which is equivalent to requiring rubber tubes to reduce elasticity as much as possible to adapt to pulse tests, and to show resilience as much as possible to meet the requirements of the pulse test. Compression set standard, obviously, this is basically an impossible task for AEM hose at present
