Problems solved by technology
Once the fuel tank is damaged, secondary damage such as oil leakage or even explosion will occur, causing devastating damage to personnel
Fuel leakage will not only increase the risk of fire and explosion, but also affect the endurance of the vehicle.
Existing fuel tanks generally do not have the function of suppressing explosion, and cannot realize self-sealing after the fuel tank is broken down, so as to suppress the leakage of fuel

Embodiment Construction
[0025] A vehicle safety fuel tank with self-sealing and explosion-proof functions, which includes a fuel tank body 10, a self-sealing layer 8 and a barrier and explosion-suppressing material 9, the top of the fuel tank body is provided with a filling port 13 for the barrier and explosion-suppressing material, which is convenient for blocking and suppressing explosions Material filling. The side of the fuel tank body is provided with an oil filling port 11, and the bottom is provided with an oil drain port 12, which is convenient for injecting fuel into the fuel tank and removing impurities in the fuel.
[0026] The self-sealing layer is coated on the outer wall of the fuel tank, which is composed of multiple layers of polymer materials with different properties, which are anti-aging coating 81, elastic fabric layer 82 with high tear resistance structure, high elastic layer 83 and oil-repellent layer. Intumescent layer 84 . Among them, the anti-aging coating is a wear-resistan...

Abstract
The invention relates to the technical field of fuel tanks, in particular to a vehicle safety fuel tank with self-sealing and explosion-proof functions. The vehicle safety fuel tank includes a fuel tank body, a self-sealing layer and a blocking and explosion suppressing material. A blocking and explosion suppressing material filling port is formed in the top of the fuel tank body, a fuel injectionport is formed in the side part of the fuel tank body, and a fuel discharge port is formed in the bottom of the fuel tank body. The outer wall of the fuel tank body is coated with the self-sealing layer, and the self-sealing layer is compounded by a plurality of layers of polymer materials with different properties which are separately the anti-aging coating, the highly-tear-resistant structure elastic fabric layer, the highly elastic layer and the fuel-swelling layer. The fuel tank body is filled with the blocking and explosion suppressing material. The vehicle safety fuel tank can be quickly self-sealed after being broken through to suppress the leakage of fuel, and has the functions of explosion proof and explosion suppression.
Description
technical field [0001] The invention relates to the technical field of fuel tanks, in particular to a vehicle safety fuel tank with self-sealing and explosion-proof functions. Background technique [0002] The damage modes of vehicle fuel system mainly include fuel supply damage, fuel tank combustion and explosion, liquid impact, etc. Once the fuel tank is damaged, secondary damage such as oil leakage or even explosion will occur, causing devastating damage to personnel. The leakage of fuel will not only increase the risk of fire and explosion, but also affect the endurance of the vehicle. Existing fuel tanks generally do not have the function of suppressing explosion, and cannot realize self-sealing after the fuel tank is broken down, so as to suppress the leakage of fuel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vehicle safety fuel tank with self-sealing and explosion-proof functions that can quickly...
