Problems solved by technology

[0003] The existing fuel tank has the following deficiencies: first, the fuel tank is a soft rubber laminated structure, and its sealing is not strong; secondly, when the existing fuel tank is used, the fuel always stays in the oil diffusion layer, and cannot touch the sealing layer. The role of the bullet cannot be reflected; again, when the bullet penetrates the fuel tank, the fuel is easy to leak, causing the hazard of oil leakage

preparation example Construction

[0042] A kind of preparation method of self-sealing fuel tank of the present invention:

[0043] The woven base cloth substrate is coated with molten colloid formed at a high temperature of 230° C., thereby forming an upper primer layer and a lower primer layer on the upper and lower sides of the substrate, forming a rubber-coated fabric 6 . Then the prepared first sealing layer 2 and the second sealing layer 3 are pasted on the rubber-coated fabric 6, and then the same rubber-coated fabric 6 is pasted on the exposed surfaces of the first sealing layer 2 and the second sealing layer 3 , and then apply an outer coat 1 on the top, and finally stick an oil-diffusion-proof layer 4 on the bottom. The bonding process is all high temperature compaction process. This process is prior art and can be performed using conventional methods.

Abstract

The invention discloses a self-sealing oil tank and belongs to the technical field of oil tanks. The self-sealing oil tank comprises a tank body which is formed by plate bodies in a combined mode. Each plate body sequentially comprises an outer coating, a first sealing layer, a second sealing layer and an oil diffusion prevention layer from outside to inside, wherein the space between the outer coating and the first sealing layer, the space between the first sealing layer and the second sealing layer and the space between the second sealing layer and the oil diffusion prevention layer are each provided with a rubber coated fabric layer. The oil tank provided by the invention has good sealing performance.

Description

technical field [0001] The invention belongs to the technical field of fuel tanks, and further relates to a self-sealing fuel tank. Background technique [0002] The fuel tank is a fuel container on an airplane or a car, and it is a special container for storing hydraulic oil or hydraulic fluid in a hydraulic system. Fuel tanks are generally mainly metal fuel tanks and non-metallic fuel tanks. Metal fuel tanks are gradually eliminated due to the fact that metal is easy to spark and cause explosions in the event of a car accident. However, the existing non-metallic fuel tanks are basically made of rubber and plastic, which not only has the effects of impact resistance, non-leakage and flame retardancy, but also has the advantages of simple structure, light weight, strong safety performance, and random shape. [0003] The existing fuel tank has the following deficiencies: first, the fuel tank is a soft rubber laminated structure, and its sealing is not strong; secondly, when ...
