Abstract

The invention provides a rubber alloy material of an ethanol-resisting gasoline diaphragm of a fuel pressure regulator and relates to a preparation method of the rubber alloy material of the ethanol-resisting gasoline diaphragm of the car fuel pressure regulator, which overcome the defects that the diaphragm which is used by the existing car fuel system regulator and takes butadiene-acrylonitrile rubber as a main material does not resist an ethanol solvent, and the cold resistance and the ozone aging resistance of the diaphragm are poor. The rubber alloy material is prepared from the butadiene-acrylonitrile rubber and chlorine ether rubber in an alloying way. The rubber alloy material is composed of the butadiene-acrylonitrile rubber, the chlorine ether rubber, a filling reinforcing agent, a vulcanizing system, a protection system, an activating agent and a plasticizer. The preparation method of the rubber alloy material comprises the following steps of: (1) plastifying; (2) mixing; and (3) vulcanizing and molding. The rubber alloy material of the ethanol-resisting gasoline diaphragm of the fuel pressure regulator, provided by the invention, has excellent oil resistance and solvent resistance and also has the cold resistance and the ozone aging resistance. The preparation method of the rubber alloy material has the advantages of simplicity, easiness in operation and less equipment investment.

Description

technical field [0001] The invention relates to an ethanol gasoline-resistant diaphragm rubber alloy material for an automobile fuel pressure regulator and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, higher and higher requirements are put forward for auto parts. Only by continuously improving the quality of parts can we manufacture high-end cars. Moreover, in recent years, in order to save energy and protect the environment, more and more clean fuels are used in the automobile industry, such as fuel oils containing additives such as methanol, ethanol or aromatic compounds. As a result, higher performance requirements are imposed on vulcanizates used in fuel oil systems. Automotive fuel pressure regulator diaphragms not only require excellent oil resistance and solvent resistance, but also have good cold resistance and high ozone aging resistance. [0003] At present, the diaphragm of automobile fuel pre...
