The utility model compared with prior art has following features: the shelter made from the utility model wallboard of shelter not only has efficient electro-magnetic screen function, also has radar invisible function.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
As shown in drawings, a kind of maintenance-free absorbing radar wave and the wallboard of shelter with electromagnetic shielding, comprise external covering board 1, adiabator layer 4 and Inner Mongol plate 5 from outside to inside successively; Described external covering board 1 is a kind of composite material laminated board, and described composite material laminated board comprises outer 1-1, internal layer 1-2, and described outer 1-1 is wave-penetrating composite material, and described internal layer 1-2 is for inhaling ripple foam; Described adiabator layer 4 is low-density polyurethane rigid foam layer; Described Inner Mongol plate 5 is for having the alloy aluminium sheet of continuous conduction; In described adiabator layer 4, compartment of terrain is provided with skeleton 2, between described skeleton 2 and described Inner Mongol plate 5, has disconnected heat bridge 3.
Described wave-penetrating composite material is Penetrating.
The resin matrix of described Penetrating is epoxy resin, the fortifying fibre of described Penetrating is quartz glass fibre, quartz glass fibre coupling agent treatment, coupling agent is methacrylic acid chromium complex, coupling agent consumption is 0.05% of quartz glass fibre quality, and in described Penetrating, the volume fraction of epoxy resin is 50%.
Described suction ripple foam is the polymethacrylimide foam that adds absorbent, and described absorbent is carbon dust and barium ferrite, and wherein, carbon dust accounts for 15% of foam gross mass, and barium ferrite accounts for 5% of foam gross mass.
The one of embodiment 1 substitutes preferred embodiment:
Described Penetrating forms like this: resin matrix is polyflon, and fortifying fibre is superhigh molecular weight polyethylene fibers, and wherein, the volume fraction of polyflon is 63%.
Described absorbent is manganese oxide and carbon black, and wherein, manganese oxide accounts for 7% of polymethacrylimide foam gross mass, and carbon black accounts for 13% of polymethacrylimide foam gross mass.
The other technologies feature of this alternative preferred embodiment is identical with embodiment 1.
Operation principle of the present utility model and using method are: the radar wave of incident, through wave-penetrating composite material layer, by the suction ripple foam absorbing of the inside, thereby is realized radar invisible function; The Inner Mongol plate of adjacent wallboard of shelter is electrically connected mutually, jointly forms the electro-magnetic screen layer of shelter, realizes shielding electromagnetic waves effect inside and outside shelter.
