Abstract
The invention discloses a shelter wallboard with a radar stealth function and capable of preventing fragment penetration and relates to the technical field of shelters. The shelter wallboard comprises an outer mask, a wave absorbing interlayer, a heat preservation material layer and an inner mask from the outside to the inside sequentially, and frames are arranged between the outer mask and the inner mask at intervals. The outer mask is made of a high-strength composite material which has good wave-transparent performance. The wave absorbing interlayer is made of wave absorbing foam. The heat preservation material layer is made of low-density polyurethane hard foam. A wave absorbing coating is coated on combined faces of the frames in contact with the outer mask.
Description
Technical field
The present invention relates to shelter technology field, particularly a kind of have a wallboard of shelter that radar invisible anti-fragmentation penetrate.
Background technology
Tradition wallboard of shelter is generally composited by Inner Mongol plate, external covering board and polyurethane foam sandwich, and Inner Mongol plate and external covering board are aluminium alloy plate.
Tradition wallboard of shelter does not have stealthy effect to radar detection; Its wallboard intensity can not be resisted the impact of explosion fragment and easily be penetrated.In prior art, also not having a kind ofly both had stealthy effect to radar detection, can resist the wallboard of shelter that explosion fragment prevents that wallboard from being penetrated again.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of radar invisible wallboard of shelter that also anti-fragmentation penetrates that has, the shelter made from it to there is function stealthy to radar detection and that can prevent from being penetrated by explosion fragment simultaneously.
Technical scheme of the present invention is: a kind of have a wallboard of shelter that radar invisible anti-fragmentation penetrate, and comprises successively from outside to inside external covering board, inhales ripple sandwich of layers, adiabator layer and Inner Mongol plate, and between described external covering board and Inner Mongol plate, compartment of terrain is provided with skeleton; Described external covering board is high-strength composite material, and described high-strength composite material has good wave; Described suction ripple sandwich of layers is for inhaling ripple foam; Described adiabator layer is low-density polyurethane rigid foam; On the faying face that described skeleton contacts with external covering board, scribble antiradar coatings.
Further, described high-strength composite material is the high-intensity fiber composite with good wave.
Further, described high-intensity fiber composite is polythene weft-less cloth/vinyl esters composite, and described polythene weft-less cloth intersects laying according to certain fiber axis anglec of rotation, and the content of described vinyl ester resin is less than or equal to 50wt%.
Further, described polythene weft-less cloth is 0 °, 90 °, 0 °, 90 ° according to the fiber axis anglec of rotation and intersects laying.
Further, described suction ripple foam is for adding the polymethacrylimide foam of absorbent, and described absorbent is manganese oxide and carbon black or carbon dust and barium ferrite.
Further, described Inner Mongol plate comprises decorative composite material layer, wallpaper, and described decorative composite material layer is clipped between adiabator layer and wallpaper.
Further, between described skeleton and described Inner Mongol plate, there is disconnected heat bridge.
The present invention compared with prior art has following features: wallboard of shelter of the present invention both had stealthy effect to radar detection, can resist again explosion fragment and prevent that wallboard from being penetrated; That the shelter made from it has is simultaneously stealthy to radar detection, can prevent the function that penetrated by explosion fragment.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of have a wallboard of shelter that radar invisible anti-fragmentation penetrate, and comprises successively from outside to inside external covering board 1, inhales ripple sandwich of layers 3, adiabator layer 5 and Inner Mongol plate 6, and between described external covering board 1 and Inner Mongol plate 6, compartment of terrain is provided with skeleton 4; Described external covering board 1 is high-strength composite material, and described high-strength composite material has good wave; Described suction ripple sandwich of layers 3 is for inhaling ripple foam; Described adiabator layer 5 is low-density polyurethane rigid foam; On the faying face that described skeleton 4 contacts with external covering board 1, scribble antiradar coatings 2; Between described skeleton 4 and described Inner Mongol plate 6, there is disconnected heat bridge 7.
Described Inner Mongol plate 6 comprises decorative composite material layer 6-1, wallpaper 6-2, described decorative composite material layer 6-1 is clipped between adiabator layer 5 and wallpaper 6-2, and described decorative composite material layer 6-1 is a kind of artificial flaggy being comprised of materials such as wood fibre and Lauxites.
Described high-strength composite material is the high-intensity fiber composite with good wave.
Described high-intensity fiber composite is polythene weft-less cloth/vinyl esters composite, and described polythene weft-less cloth is 0 °, 90 °, 0 °, 90 ° according to the fiber axis anglec of rotation and intersects laying, and the content of described vinyl ester resin is 25wt%.
Described suction ripple foam is for adding the polymethacrylimide foam of absorbent, and 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.
A kind of alternative preferred embodiment of embodiment 1:
Described polythene weft-less cloth is 0 °, 60 °, 120 °, 0 °, 120 °, 60 °, 0 ° according to the fiber axis anglec of rotation and intersects laying, and described vinyl ester resin content is 50wt%.
Described absorbent is carbon dust and barium ferrite, and wherein, carbon dust accounts for 15% of polymethacrylimide foam gross mass, and barium ferrite accounts for 5% of polymethacrylimide foam gross mass.
The other technologies feature of this alternative preferred embodiment is identical with embodiment 1.
Operation principle of the present invention and using method are:
The dielectric constant that experiment showed, polythene weft-less cloth/vinyl esters composite increases along with the increase of vinyl ester resin content, and correspondingly, its wave penetrate capability reduces along with the increase of dielectric constant.
Polythene weft-less cloth/vinyl esters composite of producing according to the technical parameter of narrating in embodiment 1, its dielectric constant is 1.99; Polythene weft-less cloth/vinyl esters composite of producing according to technical parameter in the alternative preferred embodiment of embodiment 1, its dielectric constant is 2.46, both meets electromagnetic wave transparent material dielectric constant lower than 4 requirement.On the other hand, polythene weft-less cloth has high strength and modulus, and polythene weft-less cloth/vinyl esters composite of producing by the technical parameter in embodiment 1 and alternative preferred embodiment thereof has bulletproof function.
