Flame-retardant and explosion-proof ammunition box

Abstract

The invention relates to a flame-retardant and explosion-proof ammunition box, and belongs to the field of packaging of flammable and explosive materials. The flame-retardant and explosion-proof ammunition box comprises a sealing cavity defined by a box body and a box cover fastened on the box body, and the box body and the box cover both comprise a rotational moulding outer shell, a heat insulating filling layer, a heat insulating felt or plate layer and a metal foam explosion-proof inner shell from outside to inside; a containing cavity defined by the metal foam explosion-proof inner shell of the box body is internally provided with a vibration reduction mold shell matched with ammunition in shape and specification, the rotational moulding outer shells on the box body and the box cover form a stepped limit sealing structure of snap fastening by relying on matched protrusions and notches, the metal foam explosion-proof inner shells are surrounded by the heat insulating felt or plate layers, a heat insulating felt or plate on the box cover is lower than the corresponding metal foam explosion-proof inner shell, a heat insulating felt or plate on the box body is correspondingly higher than the corresponding metal foam explosion-proof inner shell, a double-layer dislocation fastening sealing structure is formed, and the heat insulating filling layers are heat preservation materials filling gaps between the rotational moulding outer shells and the heat insulating felt or plate layers. The packaging box has multiple protection functions of flame retardance, heat insulation, vibration and shock resistance and explosion protection.

Description

technical field [0001] The invention belongs to the technical field of packaging of inflammable and explosive materials, and relates to ammunition packaging boxes, in particular to a flame-retardant and explosion-proof ammunition box which integrates flame-retardant and anti-ablation, heat-insulation and anti-explosion, and impact-resistance and vibration-reduction technologies. Background technique [0002] Ammunition is an extremely dangerous military material. Due to the needs of modern warfare and the complexity of wartime ammunition support methods, ammunition packaging must have sufficient resistance to meet the needs of safe storage, transportation, and storage during wartime. At present, our army's ammunition protection is mainly based on packing boxes. Most of the packaging materials are made of wood and steel, and a small amount of glass fiber reinforced plastic and plastic are used. The interior is fixed with brackets and vibration-absorbing materials. These packa...

AI Technical Summary

Problems solved by technology

These packaging boxes play a certain role in protecting the safety of ammunition, but wooden packaging boxes have low strength, poor protection performance, are susceptible to insects, rat bites, and are flammable and combustion-supporting.

The steel packing box has high strength, but it is easy to rust, sparks are easy to be generated when it is collided, and the heat conduction speed is fast. There are potential safety hazards in storing and transporting dangerous goods, and it is heavy and expensive.

FRP material is brittle, poor in low temperature resistance, easy to deform, short in service life, and low in cost performance

Most of the plastic packaging boxes are made of plastic injection molding, and some packaging boxes are made of resin. Due to the lack of effective insulation and impact resistance measures, temperature changes and impacts during storage and transportation will affect the physical and chemical properties of ammunition and affect the chamber. pressure and shooting accuracy, in extreme cases, it may also affect shooting and transportation safety

Moreover, most of the ammunition packaging has a single function and cannot effectively protect the ammunition

Especially for some new types of ammunition and high-precision missiles, if they are not properly stored and transported, they will not only cause functional failure, but even pose a safety hazard

In addition, due to the wide variety of packaging methods and inconsistent implementation standards, it has caused difficulties in mechanized operations of equipment, inconvenient storage and transportation in containers, and generated various wastes.
