Description

Technical Field

[0001] The invention belongs to a multifunctional ammunition packaging box, in particular to a multifunctional ammunition packaging box. Background Art

[0002] Ammunition is an important part of weapons and equipment, and is an important military material that plays a killing and destructive role in war. Ammunition has the characteristics of many varieties, long storage period, wide circulation range, and diverse transportation methods. In peacetime, the reserve of ammunition is large, while in wartime, the consumption is huge. It is a dangerous and explosive item and is easily damaged by physical and chemical factors. These characteristics of ammunition determine that ammunition packaging must have a high degree of protection reliability, as well as adaptability to loading and unloading, transportation, storage, and convenience in combat and training. In recent years, the development of ammunition packaging technology in our army has made great progress, and new packaging made of various materials has emerged. However, in general, there is still a certain gap to meet the requirements of our army in the new stage, which is manifested in the poor protection performance of ammunition packaging. The outstanding weak links are insufficient explosion isolation and anti-sympathetic explosion capabilities, weak resistance to actual combat environments such as explosion shock waves and fragment strikes, and single functions. Therefore, it is urgent to use new materials and technologies to develop new ammunition packaging boxes with light weight, good mechanical properties and environmental adaptability, strong comprehensive protection capabilities, and convenient transportation. Summary of the invention

[0003] The invention provides a multifunctional ammunition packaging box, which can provide conventional protection for ammunition and has the functions of being airdroppable, temperature controllable inside the box and serving as a shelter in wartime.

[0004] The technical solution adopted by the present invention is:

[0005] A multifunctional ammunition packaging box includes a supporting frame and a box wall; the box wall includes a wear-resistant layer, a heat-insulating layer, a foam aluminum energy-absorbing layer, a ceramic anti-penetration layer, a polymer material support layer, a temperature control layer, and a polyurethane foam layer from the outside to the inside; a buffer layer is provided at the bottom of the box. Through the provision of multiple functional layers, the outer part of the box is wear-resistant and less affected by temperature; the foam aluminum energy-absorbing layer is composed of foam aluminum of a certain thickness and density, and when the explosion shock wave hits, it absorbs energy by crushing to protect the projectile in the box; by comprehensively utilizing the crushing energy-absorbing characteristics of high-strength foam aluminum materials, the anti-penetration characteristics of anti-ballistic ceramics, and the excellent mechanical properties of polymer materials, effective protection against the combined attack of explosion shock waves and fragments can be achieved on the basis of controlling weight and size and meeting general requirements such as fire prevention, anti-static, and anti-drop. The design of this new ammunition packaging box can effectively protect against low-speed impact, external explosion, gunshot, high-speed fragmentation, fire, etc., ensuring that the new storage and transportation explosion-proof box will protect the internal ammunition and pyrotechnics from explosion when an external explosion or penetration occurs, and that the explosion of internal ammunition will not cause the ammunition in adjacent boxes to detonate, thereby ensuring the safety of ammunition in peacetime storage and transportation, as well as the safe protection of ammunition in wartime.

[0006] Furthermore, the wear-resistant layer is made of glass fiber reinforced plastic, and the outer surface of the glass fiber reinforced plastic is sprayed with a zirconia ceramic coating. In terms of structural ceramics, since zirconia ceramics have the advantages of high toughness, high bending strength and high wear resistance, excellent thermal insulation performance, and a thermal expansion coefficient close to that of steel, the practicability of the box is enhanced by spraying a zirconia ceramic coating on the outer surface as a wear-resistant layer.

[0007] Furthermore, the heat insulation layer is aluminum silicate, and the aluminum silicate is sprayed on the inner surface of the wear-resistant layer. Aluminum silicate is used as filler for glass, pottery, pigments and paints, and is used to make high-temperature resistant fireproof sound insulation and heat insulation cotton, boards, pipes, seam felt, fireproof heat insulation cloth, high-temperature resistant paper, fireproof heat insulation rope, belt, fireproof heat insulation needle-punched blanket, bricks, inorganic fireproof decorative board, which has good heat insulation performance, avoids external temperature influence, and improves practicality.

[0008] Furthermore, the ceramic anti-penetration layer is a bullet-resistant ceramic, which is an oxide ceramic, a carbide or a boride ceramic. Bullet-resistant ceramics are also called bulletproof ceramics. Ceramics absorb the kinetic energy of projectiles due to their rupture. The ceramic armor system is composed of a single piece of ceramic or a ceramic-metal composite covered with a nylon cloth layer combined with high tensile strength organic fibers. The ceramic anti-penetration layer is provided to prevent the penetration of high-speed fragments and bullets.

[0009] Furthermore, the anti-bullet ceramic is boron carbide ceramic. A notable feature of boron carbide ceramic is that it is very hard, with a microhardness of about 50,000 MPa (ie 50 GPa), second only to diamond (90-100 GPa) and CBN (80-90 GPa); the hardness of boron carbide ceramic is used to increase the anti-bullet performance of the box.

[0010] Furthermore, the polymer material support layer includes an ultra-high molecular weight polyethylene plate and a carbon fiber plate, and the ultra-high molecular weight polyethylene plate and the carbon fiber plate are bonded and connected. The polymer material support layer is formed by bonding the ultra-high molecular weight polyethylene plate and the carbon fiber plate with an adhesive, and its function is to provide support strength for the ceramics and give full play to the anti-penetration performance of the ceramics; Ultra-high molecular weight polyethylene is the English name: Ultra High Molecular Weight Polyethylene, which is the best quality polyethylene available that can be used in harsh working environments and for a variety of purposes. It has very good applicability under many difficult application conditions.

[0011] Furthermore, the temperature control layer is a graphene-modified paraffin composite material. The temperature control layer is a functional layer, which can be filled with ice cubes or fillers with electric heat conversion and heat storage functions, or graphene-modified paraffin composite materials with phase change heat storage functions as needed, and its function is to adjust the temperature inside the box.

[0012] Furthermore, the buffer layer is foamed aluminum, and the density of the foamed aluminum of the buffer layer decreases from bottom to top.

[0013] Furthermore, the polyurethane foam layer is provided with a plurality of holes in a direction perpendicular to the box wall. The innermost layer close to the ammunition is composed of polyurethane foam, which is used to provide cushioning and protection for the ammunition, and a certain number of holes are provided in the middle of the polyurethane material in a direction perpendicular to the box wall for heat exchange.

[0014] Furthermore, the supporting frame is made of high-strength aluminum alloy.

[0015] The present invention has the following advantages and beneficial effects:

[0016] 1. The present invention achieves wear resistance on the outside of the box and little influence of temperature by setting up multiple functional layers. It comprehensively utilizes the crush energy absorption characteristics of high-strength foam aluminum materials, the anti-penetration characteristics of bullet-proof ceramics, and the excellent mechanical properties of high-molecular polymer materials. It can achieve effective protection against the combined impact of explosion shock waves and fragments on the basis of controlling weight and size and meeting general requirements such as fire prevention, anti-static, and anti-drop. Through the design of this new ammunition packaging box, it can effectively protect against low-speed impacts, external explosions, gunshots, high-speed fragments, fires, etc., ensuring that the new storage and transportation explosion-proof box protects the internal ammunition and pyrotechnics from explosion when an external explosion or penetration occurs, and that the explosion of internal ammunition does not cause the ammunition in the adjacent box to explode, thereby achieving the safety of ammunition in peacetime storage and transportation, as well as the safety protection of ammunition in wartime;

[0017] 2. The present invention can be used for ammunition airdrop; in wartime, it can be used as a shelter to prevent bullet shooting and explosion shock waves and fragments; by setting the temperature control layer as a functional layer, it can be filled with ice cubes or fillers with electric heat conversion and heat storage functions, or graphene modified paraffin composite materials with phase change heat storage function as needed, which is used to adjust the temperature in the box;

[0018] 3. The box of the present invention can maintain a certain temperature, and the performance of the ammunition will not be affected under high-cold areas and tropical exposure conditions. BRIEF DESCRIPTION OF THE DRAWINGS
