Cylindrical high polymer material composite flexible explosion-proof tank and preparation method thereof

Abstract

The invention discloses a cylindrical high polymer material composite flexible anti-explosion tank and a preparation method thereof.The cylindrical high polymer material composite flexible anti-explosion tank comprises a cylindrical tank body, and the cylindrical tank body comprises a first anti-explosion structure unit and a second anti-explosion structure unit which are sequentially arranged from inside to outside; each of the first anti-explosion structure unit and the second anti-explosion structure unit comprises a first flexible anti-explosion layer, a second flexible anti-explosion layer and a third flexible anti-explosion layer; and the second flexible explosion-proof layer is arranged between the first flexible explosion-proof layer and the second flexible explosion-proof layer. The anti-explosion tank prepared through the method is light in weight, convenient to move and high in protection capacity, after explosives explode in the tank body, splashing fragments can be all bound in the tank body, the tank body cannot generate explosion fragments, and the basic structure of the anti-explosion tank can be kept.

Description

technical field [0001] The invention relates to a cylindrical polymer material composite flexible explosion-proof tank and a preparation method thereof, belonging to the explosion-proof technical field. Background technique [0002] Explosion-proof cans are a type of equipment that can prevent and reduce damage to surrounding personnel or facilities when explosives explode. Explosion-proof tanks are mainly used for safe transportation, transfer, and temporary storage of explosives. There are five types of explosion-proof tanks in the shape of box, barrel, T, spherical and portable miniature, usually divided into fixed type and mobile type. It can also be equipped with a tractor for the collection of explosives in the field; the explosives mainly come from the remnants of war explosives and terrorist attack explosives and criminal explosives. Once the explosives explode, the power of the explosion itself will cause great damage to the scene. The shock wave and explosion spat...

AI Technical Summary

Problems solved by technology

[0003] Prior to this, explosion-proof tanks were all made of high-strength metal materials to resist the explosion of explosives and reflect most of the shock waves and splashes of explosion fragments. Rigid explosion-proof tanks; and Chinese patents CN202022928958.0, CN202020963497.8, and CN202022918455.5 also announced rigid explosion-proof tanks with different performances and different uses. The above-mentioned rigid explosion-proof structures are mainly aimed at the strong shock waves generated by explosions. The high wave impedance reflects most of the shock waves and disperses and transfers the explosion energy. While having strong protection capabilities, it has the disadvantages of heavy weight, poor mobility, and inconvenient movement, and the rigid explosion-proof tank itself may cause secondary fragment damage as a fragment , so the disposal device for improvised explosives is gradually becoming lighter and does not cause secondary damage, which has become a development trend that urgently needs to replace traditional explosion-proof tanks

[0004] A honeycomb explosion-proof tank disclosed in Chinese patent CN202110643589.7, a hollow annular flexible explosion-proof tank structure and its design method disclosed in Chinese patent CN202010996794.7, and a composite explosion-proof structure based on polyurethane / liquid disclosed in Chinese patent 202010456600.4 And its preparation method, although use macromolecule material in the above-mentioned explosion-proof tank structure, have the explosion-proof tank of hollow annular flexible structure, after the explosive explodes, the destructive effect of the shock wave is obviously weakened, and certain explosion-proof ability has been played, but when the explosion-proof tank body is completely It will become explosion fragments and splash around the explosion point
