Embodiment Construction

[0038] Such as figure 1 As shown, the present invention has a flame-retardant, high and low temperature resistant, oil-resistant fluorine inner and outer silicone tube, which includes an inner rubber layer 1, a middle rubber layer 2, a skeleton layer 3 and an outer rubber layer 4 from the inside to the outside.

[0039] The raw materials of the inner rubber layer 1, the middle rubber layer 2, the skeleton layer 3 and the outer rubber layer 4, and their component weight ratios are:

[0040] Inner rubber layer 1: Fluorosilicone rubber: 80-120 Gas-phase method silicone rubber: 10-30

[0041] Defrost agent: 0.5-1 Vulcanizing agent: 1-2

[0042] Ferric oxide: 1-3 PTFE: 2-5

[0043] Antimony trioxide: 3-6 3.5H 2 O zinc borate: 8-15

[0044] Silazane: 1-3 Decabromodiphenyl ether: 7-15

[0045] Fumed silica: 3-6 Color masterbatch: 1-2;

[0046] Middle rubber layer 2: Fluorosilicone rubber: 20-70 gas-phase method silicone rubber 50-80

[0047] Masterbatch...

Abstract

The invention discloses an inner-fluorin and outer-silicon tube with fire resistance, high and low temperature resistance and oil resistance and a preparation method thereof. The inner-fluorin and outer-silicon tube sequentially comprises an inner rubber layer, a middle rubber layer, a framework layer and an outer rubber layer from inside to outside. The problems of low high and low temperature resistance of a traditional ethylene acrylate rubber tube (AEM) and relatively low oil resistance of a silicone tube (VMQ) are solved through the inner-fluorin and outer-silicon tube. Through the improvement of a material and a processing process, the inner-fluorin and outer-silicon tube has fire resistance as well as excellent high and low temperature resistance and oil resistance.

Description

technical field [0001] The invention relates to a connecting rubber hose for a turbocharger of an automobile, in particular to a fluorine-inner and outer-silica gel hose with flame retardancy, high and low temperature resistance, and oil resistance and a preparation method thereof. Background technique [0002] With the progress of society and the development of human beings, people's requirements for energy and environmental protection are getting higher and higher. In the automobile industry, in order to improve energy efficiency and automobile emission standards, people are constantly pursuing new technologies, among which the application of turbocharger technology is the mainstream trend of automobile development. [0003] Turbocharger technology is to use the exhaust gas to drive the turbocharger to compress the air, increase the intake air volume of the engine, increase the oxygen content, and make the fuel burn more fully. The turbocharger makes the air temperature ri...
