Embodiment 1-5

[0051] Using butyl rubber with 34% acrylonitrile as raw material, two-component adhesive 1 and two-component adhesive 2 are two-component adhesives of Russian Red Star Chemical, and ether ester ABD-30 is used as raw material. The raw material is ether ester, and the cross-linking agent TAC is the cross-linking agent; and the appropriate amount of each raw material is weighed according to the raw material ratio shown in the following table to obtain the nitrile rubber material formula of Example 1-5:

[0052] Table 1 Example 1-5 Nitrile rubber material formula

[0053]

[0054] Then, the nitrile rubber composite fluororesin multilayer fuel hose of Example 1-5 was prepared according to the steps shown below, and the specific preparation steps are as follows:

[0055] (1) After mixing the nitrile rubber compositions described in Examples 1-5 separately, perform the first stage mixing at 110-140°C, and then perform the second stage mixing at 90-120°C, The nitrile rubber material of Exam...

Abstract

The invention provides a nitrile rubber-compounded fluororesin multi-layer fuel rubber pipe. By adjusting components of nitrile rubber and usage amounts of the components, the nitrile rubber has good oil-resistant and high and low temperature aging-resistant properties, and also has good sticking property with fluororesin with good fuel permeation-resistant and separation properties. A method has the advantages that by using the nitrile rubber as an outer rubber layer material, the prepared rubber pipe has good oil-resistant property, good sticking property with a fluororesin middle rubber layer, an enhancing layer and a protective layer, and good structure integrity; by arranging a weaving layer and the protective layer, the mechanical property of the rubber pipe is improved, and the usability of the rubber pipe is improved.

Description

Technical field [0001] The invention relates to the field of fuel hoses, in particular to a multi-layer fuel hose made of nitrile rubber composite fluororesin. Background technique [0002] Automobile fuel hoses, including fuel delivery pipes and fuel hoses that supply fuel to the engine, are important safety parts. Therefore, the performance requirements for fuel hose materials are also high. Generally speaking, the inner layer of automobile fuel hose should be made of materials with good resistance to fuel medium and heat resistance; the outer layer should be made of materials with good heat resistance, ozone resistance, environmental resistance and good adhesion to the inner layer of rubber. . [0003] Safety, energy saving and environmental protection are the eternal themes of the development of automobile technology. In order to solve the pollution and safety problems caused by the penetration of fuel into the atmosphere through the wall of the hose, people have also made a ...
