Automobile booster rubber tube

Abstract

The invention relates to an automobile booster rubber tube. The automobile booster rubber tube comprises an inner layer (1). The inner layer (1) is made of fluororubber, a middle layer (2) is arrangedon the outer side of the inner layer (1), an outer layer (3) is arranged on the outer side of the middle layer (2), the middle layer (2) and the outer layer (3) are both made of ethylene-acrylate rubber, aramid fiber threads (4) are arranged between the middle layer (2) and the outer layer (3), and a reinforcing layer is formed by the aramid fiber threads (4). By means of the automobile booster rubber tube, the production cost is reduced, the pressure resistance, expansion resistance and low permeability of the product are improved, and good high temperature resistance is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile auxiliary equipment, and relates to an accessory for an automobile supercharger, in particular to an automobile supercharger rubber hose. Background technique [0002] At present, more and more cars will use turbochargers as standard equipment. Rubber hoses are required in turbochargers. However, the high temperature nature of turbochargers makes most rubber unsatisfactory. [0003] At present, fluorine rubber is the mainstream material for turbocharger hoses. That is, if figure 1 As shown, the entire turbocharger hose is made of Viton, and the wall thickness of the entire hose is 2.5-3.0mm. However, the high price of fluorine rubber makes the relative cost of turbocharger hose relatively high. How to reduce the cost of turbocharger hose to reduce the overall cost of turbocharger and increase the effective competitiveness of the huge market of turbocharger hose become an urgent problem. ...

Problems solved by technology

However, the high price of fluorine rubber makes the relative cost of turbocharger hose relatively high. How to reduce the cost of turbocharger hose to reduce the overall cost of turbocharger and increase the effective competitiveness of the huge market of turbocharger hose become an urgent problem

[0004] At the same time, the hose using fluororubber is not only costly, but also due to the poor processing performance of fluororubber, the product qualification rate is low, which further increases the cost.

Moreover, the structure made purely of fluorine rubber makes the product relatively poor in pressure resistance, easy to expand, etc., and the service life is relatively low under long-term use

Moreover, the hose made of fluororubber is permeable, and it is difficult to meet the low-emission environmental protection requirements required by the National VI

At the same time, its weight is relatively large, which is difficult to meet the lightweight requirements of the automotive industry
