Description
Technical field
The utility model relates to shellproof technical fields, more particularly to a kind of polyurethane armour.
Background technique
Armour is general that flak jackets is cooperated to use as important Individual Protection Kit, be protect individual soldier from bullet and
Effective equipment that elastic slice directly injures.The ceramic wafer for armour relatively common at present is mainly selected from aluminium oxide, nitridation
One of aluminium, silicon nitride, silicon carbide, boron carbide, pink fused alumina, titanium boride, glass ceramics, Functional Graded Ceramics or in which several
Combination, be also possible to wherein several composite ceramics, metal plate is mainly that anti-bullet steel plate, titanium alloy sheet, aluminium alloy plate, zinc close
One of golden plate, magnesium alloy plate, nickel alloy plate or in which several combinations, high-intensity fiber are mainly selected from aramid fiber, gather
One of vinyl fiber, glass fibre, polypropylene fibre, polyester fiber, nylon fiber, poly- heteroaromatic such as PBO, PBT fiber
Or in which several combination.
These innovative materials and structure can realize the effect for resisting bullet shooting well, but still remain one
Problem, it is well known that speed when bullet shooting is very high, has very big kinetic energy, and the moment with penetration is being hit with armour,
Energy transmission makes armour surface failure of rock or recess to armour, so that shellproof inner cord is recessed and instantaneous deformation is transmitted to
Buffer layer and human body, the very big instantaneous deformation of a pocket easily cause the impaired of tissue and bone, such as: it is shellproof
Plate has resisted the shooting of bullet well, and the case where fracture of rib or visceral injury etc. but still occurs in wearer.
The armour of fritter ceramic block composition is designed by structure solves linking seam defect, can be very good to meet and resists son
The requirement hit is launched, but bullet shooting can be such that stress excessively concentrates on single ceramic block, fall into after ceramic block, make to human body
At impact.Scrim cloth pressing plate and ceramic wafer bonding pressing, in bullet Penetration, ceramic wafer is broken, scrim cloth pressing plate
Due to pressure failure, the deformation of scrim cloth pressing plate causes to impact adhesive between ceramic wafer to human body.
Individual soldier in operation, is needed to be worn on soldier and enters and leaves various battlefield surroundings with it, it is easy to met with armour
To high temperature, high humidity, soaked, sleet and snow ice, the harsh weather such as exposure in sunshine and environment, bulletproof ceramic, metal, macromolecular fibre are long
Time is under this environment, and some changes, such as aging, corrosion, while the weight gain that absorbs water, surface can all occur for structure and performance
The problems such as ice-cold, also will affect the wearing experience of soldier.
Currently, the complex method of armour mostly uses monolithic ceramic plate and high-performance fiber tissue layer pressing plate to pass through adhesive
It directly bonds, or small pieces spliced ceramic is bonded directly to be combined on fabric laminate.The former is by bullet
Easily cause the whole fragmentation of ceramic wafer to influence bulletproof effect after impact；And the armour of the latter's preparation, due to potsherd
Between gap caused by local weak easily cause running through for bullet after armour is by bullet impact.
Utility model content
The purpose of this utility model is to overcome ceramic bulletproof plates of the existing technology due to local weak or porcelain
The problem of gap between piece causes local bullet to puncture and cannot keep out adverse circumstances, provides a kind of polyurethane armour, should

To achieve the goals above, the utility model provides a kind of polyurethane armour, including silicon carbide layer and polyurethane
Layer；
The silicon carbide layer is that structure is reticulated by silicon carbide fibre cross arrangement, and 5-30 layers of repeated arrangement；
Angle between silicon carbide fibre described in same layer is 0-180 °；Angle between the different layer silicon carbide fibre is 5-
175°；
The layer of polyurethane is the polyurethane through high pressure painting to silicon carbide layer surface；
Layer of polyurethane described in multiple groups is by adhesive bonding to obtaining armour inner body together.
Preferably, layer of polyurethane with a thickness of 5-50mm.
Preferably, fire-retardant filler is added in the polyurethane material.
Preferably, the grammes per square metre of the silicon carbide fibre is 50-500g/m2。
Preferably, the angle between silicon carbide fibre described in same layer is less than the angle between the different layer silicon carbide fibre.
Preferably, the armour inner body is bonded two sides by stretch fabric bound edge, non-woven fabrics.
Preferably, the stretch fabric is wear-resisting knitting stretch fabric.It can be prevented outside armour using wear-resisting knitting stretch fabric
Surface is since long-time is using wearing.
Preferably, the layer of polyurethane is 2-10 layers.
Through the above technical solutions, can achieve it is following the utility model has the advantages that
(1) toughness and intensity of armour are improved by the compound use of multilayer silicon carbide fibre and polyurethane material.
(2) high temperature resistance of armour is improved using silicon carbide fibre.
(3) the lesser silicon carbide fibre of density and polyurethane material are used, whole weight can be greatly reduced, in human body
There is very big application space in the fields such as protection, bullet-proof vehicle, helicopter.
It (4), can be effective since polyurethane material has the high intensity of good ability of anti-deformation and silicon carbide fibre
Prevent the injury as caused by armour elastic deformation.
(5) there is good resistance to low temperature, and anti-corruption with higher using armour prepared by this polyurethane material
Corrosion.
