Embodiment

[0041] According to the component ratios in Table 1, the production of rubbers for automobile turbocharger pipes in Examples 1 to 4 was carried out.

[0042] The AEM rubber for automobile turbocharger pipe of the present invention is manufactured according to the following steps:

[0043] (1) Preparation of materials: According to the ingredients and proportions in Table 1, ethylene acrylate rubber, carbon black, softening plasticizer, anti-aging agent, and processing aid were weighed and mixed to form ingredient A, and the vulcanizing agent was weighed to form ingredient B;

[0044] (2) The first mixing: put the components in ingredient A except carbon black and softening plasticizer into an internal mixer for 60-90 seconds, then lift the hammer to clean, and then put in carbon black and softening plasticizer to press The hammer is mixed for 60 to 90 seconds, and the hammer is lifted and cleaned again, and then the hammer is mixed for 30 to 60 seconds to discharge the materi...

Abstract

The invention discloses an AEM rubber for vehicle turbocharging pipes, wherein the AEM rubber comprises, by weight, 60.0-70.0% of a vinyl acrylate rubber, 25.0-35.0% of carbon black, 2.0-4.0% of a softening plasticizer, 1.0-2.0% of an anti-aging agent, 1.0-2.0% of a processing aid, and 2.0-4.0% of a vulcanizing agent. According to the present invention, the AEM rubber has characteristics of high-temperature resistance, oil resistance, thermo-oxidative aging resistance, ultraviolet radiation resistance, good low-temperature brittleness, enough use strength and the like in a use environment.

Description

technical field [0001] The invention belongs to the field of rubber, and particularly relates to AEM rubber for automobile turbocharger pipes and a preparation method thereof. Background technique [0002] Turbocharged engines have the characteristics of sufficient fuel combustion, large power output and low emissions, and are developing rapidly in line with the development trend of energy saving, emission reduction, safety and environmental protection. [0003] Whether the turbocharged engine adopts a mechanical supercharging system, an exhaust gas turbocharging system or a compound supercharging system, the temperature of the compressed gas will increase after leaving the compression chamber, and the temperature entering the turbocharger outlet hose is generally 190-250 °C. ℃; the gas needs to be cooled between the compression chamber and the engine. The temperature of the cooled gas varies with the intake air temperature, the cooling effect of the intercooler and the pipi...
