Problems solved by technology

With the rapid development of modern industry, the environmental conditions of industrial products are getting worse and worse, and higher requirements are put forward for the performance of products. The existing rubber materials have some defects of their own, and the products produced by them are often difficult to meet. Performance requirements restrict its use in industrial products to a large extent
[0003] At present, in the prior art, there have been researches on the use of EPDM rubber and chlorinated polyethylene rubber to make rubber hoses for automobiles. Although compared with conventional automobile rubber hoses, its high temperature resistance and oil resistance have been improved to a certain extent. But the effect is still not ideal enough to meet higher requirements

Description

technical field [0001] The invention relates to a modified rubber material for automobile rubber hoses and a preparation method thereof, belonging to the technical field of rubber materials. Background technique [0002] Hose is a type of tubular rubber product used to transport gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layers and a skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of neoprene, nitrile rubber, etc. With the rapid development of modern industry, the environmental conditions of industrial products are getting worse and worse, and higher requirements are put forward for the performance of products. The existing rubber materials have some defects of their own, and the p...
