Abstract

The invention discloses a fuel oil rubber tube and a preparation method thereof. The fuel oil rubber tube comprises a rubber tube body, wherein the rubber tube body comprises an inner rubber layer, areinforced fabric layer and an outer rubber layer from inside to outside in sequence, the reinforced fabric layer comprises parallel reinforced yarn arranged in the longitudinal direction of the fabric and yarn vertically intersecting with the reinforced yarn, the inner rubber layer is made of hydrogenated butadiene-acrylonitrile rubber, and the outer rubber layer is made of EPDM (ethylene propylene diene monomer). The preparation method of the fuel oil rubber tube comprises steps as follows: preparation of the inner rubber layer, weaving or winding of the reinforced fabric layer, preparationof the outer rubber layer, vulcanization and finished product checking. A fuel oil electric nozzle for an automobile is good in oil resistance, high-temperature resistance and wear resistance, low inpenetrability, resistant to low temperature, high in compressive strength, anti-aging and durable.

Description

technical field [0001] The invention belongs to the technical field of rubber hose manufacture, and in particular relates to a fuel rubber hose and a preparation method thereof. Background technique [0002] As my country's cars enter thousands of households and become a kind of travel tool for people, the automobile industry has developed rapidly, and the output of automobiles has increased year by year. The output and quality of special cars have been in line with international standards. Put forward new pursuits, and at the same time put forward higher expectations for social and economic benefits such as environmental protection, fuel saving, durability, and low maintenance costs. Many, long-distance operation puts forward higher requirements on the reliability of vehicles. The design institutes of major and medium-sized automobile manufacturing companies have launched many new models with compact structure, high speed, low fuel consumption, few failures, and environmental...
