Embodiment 1

[0026] like figure 1 The composite plate shown in the figure is from top to bottom (from outside to inside when used as a box body material) in order of magnetic wave-absorbing material layer 1, bulletproof steel plate 2, unsaturated polyester resin doped with reinforcing fibers 3, polymer microporous material Layer 4, polyurethane adhesive 5, glass fiber reinforced resin composite material layer 6, polyamide viscoelastic resin 7 and conductive elastic alloy layer 8.

[0027] The magnetic wave-absorbing material layer 1 is formed by spraying a magnetic wave-absorbing material (such as a wave-absorbing coating composed of ferrite and other magnetic fillers dispersed in a dielectric polymer) on the bulletproof steel plate 2, and the coating thickness is About 0.3-0.5 mm; the bullet-proof steel plate is a 22Si2Mn2 type hot-rolled steel plate smelted in an electric arc furnace, with a thickness of about 5-10 mm. The polymer microporous material layer 4 adopts the ROHACELL series...

Embodiment 2

[0041] like figure 2, The bulletproof steel plate 2 can adopt a corrugated structure, which has the characteristics of light weight, high strength and low cost under the same load. The outer surface is uniformly coated with magnetic wave-absorbing material 1, and the polymer microporous material layer 4 can be fully filled in the gap between the corrugated bulletproof steel plate 2 and the glass fiber reinforced resin composite material layer 6 through effective technological means or methods, It can prevent moisture, buffer bullet penetration, and attenuate the impact of explosions. In addition, it also has high light reflection performance to prevent the bubbling of the car compartment caused by the high temperature of the sun. The inner layer is a conductive elastic alloy layer 8, which can make the aluminum alloy plate shield the external electromagnetic radiation and at the same time guide and eliminate the internal static electricity.

[0042] The bulletproof steel pla...

Embodiment 3

[0045] image 3 It is only a schematic diagram of the structure, and some structures (such as the microporous material layer) are not drawn, which is only convenient for the following description.

[0046] The glass fiber reinforced resin composite material layer 6 is used as a honeycomb sandwich core, and the surfaces are bulletproof steel plates 2 and high elastic conductive alloy 8 respectively, and the glass fiber reinforced resin composite material layer 6 is made into a honeycomb shape, and the above example is used between the conductive alloy layer In the resin bonding, the upper layer of the honeycomb sandwich material (or glass fiber reinforced resin composite material layer) is a microporous material bonded with resin. In a word, the difference from the above example is that only the glass fiber reinforced resin composite material layer 6 is no longer It is a simple flat structure, but a honeycomb structure, and the other layers remain unchanged. This kind of steel...

Abstract

The invention provides a composite board and application thereof as a composite material for a fireworks and crackers transport vehicle carriage. The composted board proved by the invention comprises an armor plate, a polymer cellular material layer, a glass fiber reinforcement resin composite layer and an electric-conduction elastic alloy layer. The armor plate and the polymer cellular material layer can be bonded together with unsaturated polyester resin doped with reinforced fibers. The polymer cellular material layer and the glass fiber reinforcement resin composite layer can be bonded together with a polyurethane adhesive. The glass fiber reinforcement resin composite layer and the electric-conduction elastic alloy layer can be bonded together with polyamide viscoelastic resin. The composite board provided by the invention has the characteristics of light weight and high strength and multiple functions of retarding flames, insulating heat, attenuating the vibration of explosive blasts, conducting and dissipating static electricity and preventing radio frequency. The fireworks and crackers transport vehicle carriage made of the composite boards can sufficiently guarantee the transportation safety of explosives, such as fireworks, crackers and the like.

Description

technical field [0001] The invention relates to a composite plate and its use as a composite material for a carriage body of a firework and firecracker transport vehicle. Background technique [0002] When loading and transporting explosives (such as fireworks and firecrackers, explosive equipment, dangerous chemical materials and low-ignition combustible materials, etc.), protective measures such as impact resistance, heat insulation, radio frequency protection, and static electricity dissipation should be implemented to prevent flammable and explosive The thing exploded. However, the materials currently used for the compartments or containers loaded with inflammable and explosive materials cannot fully meet the above requirements. For example, currently, the carriage body of a transport vehicle loaded with fireworks, firecrackers and blasting equipment is usually an ordinary carriage body, and the material of the carriage body plate is generally a two-layer or three-layer...
