Abstract

The invention relates to a rubber composition for preparing external and internal layers of an automotive turbocharged hose. The rubber composition comprises 100 parts of ethylene acrylate rubber, 1.0-3.0 parts of anti-aging agent, 1.0-3.0 parts of processing agent, 10.0-20.0 parts of plasticiser, 50.0-70.0 parts of carbon black, 0.5-1.5 parts of internal releasing agent, 2.0-3.0 parts of vulcanization activator and accelerator and 1.0-2.0 parts of vulcanizing agent. The invention further provides a preparation method for the rubber composition. The rubber composition improves high temperature resistance and oil resistance, reduce compression permanent sets, and is not prone to scorching, good in processing characteristics, and can serve as the external layer and the internal layer of the automotive turbocharged hose.

Description

technical field [0001] The invention relates to a rubber composition, in particular to a rubber composition used for manufacturing an inner and outer rubber layer of an automobile turbocharger hose and a production method thereof. Background technique [0002] Ethylene acrylate refers to a copolymer composed of ethylene, methacrylate and vulcanized monomers. It has excellent heat resistance, good oil resistance and chemical properties, as well as good compression set resistance and low temperature flexibility. Ethylene acrylate rubber can be widely used in the automotive industry, including powertrain seals and gaskets, rocker cover seals, transmission oil cooling pipes, turbocharger hoses, crankcase ventilation pipes, outer casings of fuel and refrigerant hoses Layers, O-rings, shock absorbers, spark plug guards and crankshaft dust covers, etc. However, there are problems of poor resistance to low aniline oils (such as IRM 903 oil) and polar solvents, and poor high-tempera...
