Abstract

The utility model relates to a composite transparent bulletproof plate used for meeting the requirements of safety protection, such as bullet protection, explosion protection, etc. under light absorbing condition. The cross section of the utility model is in a lamellar structure, and the utility model is composed of a polycarbonate anti-squashing light absorbing plate and a glass plate. The combination type can be one of the types, such as cementing, frame holding and mechanical clamping. In a good embodiment, the surfaces between the glass and the polycarbonate are attached with transparent thin films. The utility model can effectively prevent 7.62 millimeters DAT51 type general steel core bullets of Seven-nine type miniature submachine guns and Five-four type pistols from penetrating at a speed of 530 meter per second. The utility model has the advantages of high bulletproof level, dense shooting protection, unidirectional bulletproof property, low price, light weight, wide use, etc.

Description

Composition transparent bullet-proof plate

The utility model relates to armour, refers in particular to a kind of composition transparent bullet-proof plate.

Military, public security and anti-terrorism activity, various fields such as antitheft public security, that its building, vehicle etc. have is shellproof under the daylighting condition, explosion-proof, anti-ly pound, the security protection needs of antitheft, fire prevention, antiultraviolet.

Usually, glass is purposes transparent material comparatively widely, but the weakness of Glass breadks easily, can not guarantee shellproofly, explosion-proof, anti-to pound, the needs of security protection such as antitheft, fire prevention.

At present, transparent bullet resistant material has the U.S. to produce polycarbonate LEXGARD Bullet-proof Lighting Board, and the U.S. produces Armarshield (PET material) book film (China claims armor paper tinsel film), MULTILAYER COMPOSITE doubling glass etc.

Though polycarbonate LEXGARD Bullet-proof Lighting Board has preferably integrated protection and uses processing characteristics, because its fancy price is not suitable for the present ability to shoulder economically of China, can not be as purposes widely.

Armor paper tinsel film is pasted on glass surface, and shellproof grade is low, is subjected to the influence of weather, processing, glass quality, and poor reliability can not prevent the mass of fire, resist and pound poor performance, can not solve the shellproof needs of vehicle.

MULTILAYER COMPOSITE doubling glass quality is heavy, suitability for secondary processing is poor, be not easy to processing, shellproof grade is low, and the back side, back of being hit by a bullet produces a large amount of fragments and splashes, easily cause the secondary injury, the mode of production to the special processing of specific dimensions, be unfavorable for production, the transportation of dimensions how wide in variety, inconvenience is used for the purposes of bullet-proof vehicle repacking.

The security condition and case of firearms and the most of armed analysis of cases of running off in society present according to China, main armed case is a 5-4 type pistol, the lethality of the May 4th formula is well-known with its superpower power in the world, the general steel core bullet of 5-4 type pistol emission DAT51B formula has stronger penetration power, is that armor paper tinsel film and MULTILAYER COMPOSITE doubling glass can not be guaranteed.

The purpose of this utility model provides a kind of composition transparent bullet-proof plate, makes it simple in structure, can prevent the general steel core bullet of 7.26mmDAT51B formula effectively with the penetrating of bullet speed 530m/ second, and processability is good, in light weight, price is low.

The purpose of this utility model is achieved in that a kind of composition transparent bullet-proof plate, and its cross section is a layer structure, is to pound plane skylight and glass plate combines with one deck polycarbonate LEXAN is anti-.The anti-plane skylight of pounding of described polycarbonate can be that the LEXAN-MR5 abrasionproof is spent any in type or the LEXAN-XL constructure type.Described glass can be respectively simple glass, the MULTILAYER COMPOSITE doubling glass, and safety glass, its specification, shape are not limit.The anti-compound mode of pounding plane skylight and glass of described polycarbonate LEXAN can be to use bonding respectively, any during framework clamping, machinery fix.

In preferred embodiment, on described glass surface, be pasted with transparent membrane.Its paste position is prevented pounding between the plane skylight at glass and Merlon LEXAN, and the armour thickness after the combination is between 5-30mm.

The utility model has following actively useful effect:

1. shellproof grade height: use anti-plane skylight LEXAN-MR5 abrasionproof flower type or the LEXAN-XL constructure type (not abrasionproof flower type) pounded of Merlon.With 10 millimeters glass combination, can protect penetrating of 7.62 millimeters mini-submachine gun emission general steel core bullets of DAT51B formula of 79 formulas effectively.

Use penetrating of the general steel core bullet of DAT51B formula that LEXAN-MR5 abrasionproof flower type or LEXAN-XL constructure type and 8 millimeters glass combination just can prevent completely effectively that 5-4 type pistol from launching.

2. the anti-mass of fire: will have the performance that the anti-preferably mass of fire penetrates behind simple glass or the transparent book film of safety glass stickup last layer.

3. unidirectional bullet-proof: easy, shellproof, explosion-proof, the anti-grade height of pounding of transparent bullet-proof plate compound mode, unidirectional ballistic performance makes the protege under effectively protecting, and also can fight back to the invador.

4. cheap: the transparent bullet-proof plate price is low, all is better than under the quality of armor paper tinsel film and MULTILAYER COMPOSITE doubling glass in barrier propterty and processing characteristics, price only becomes flat with it.

5. light weight.

6. processing characteristics is good.

7. of many uses: as mainly to be applicable to bank counter, armoured van, quartermaster equipment exhibition area, key departments of government, museum, kitchen, valuable ornaments shop window, personage's dwelling house, large-scale commercial building, shellproof, explosion-proof, the anti-transparent lighting material of pounding of common gaol etc.

Now in conjunction with the accompanying drawings with preferred embodiment.

Fig. 1 is the schematic diagram that the utility model uses the embodiment of bonding combination.

Fig. 2 is the embodiment that the utility model uses framework clamping combination, is local parting schematic diagram.

Fig. 3 is that the utility model uses machinery to fix the embodiment of combination.

Composition transparent bullet-proof plate of the present utility model, its cross section is a layer structure, is to pound plane skylight and one deck glass plate combines with one deck polycarbonate LEXAN-MR5 or LEXAN-XL are anti-.

Composition transparent bullet-proof plate shown in Figure 1 is pounded plane skylight 1 by LEXAN is anti-, and simple glass plate 2 combines layer structure with binding agent 3 bondings.

The structure of composition transparent bullet-proof plate embodiment shown in Figure 2 is by anti-plane skylight 1, the simple glass plate 2 pounded of LEXAN; and on glass plate 2, be pasted with transparent membrane 4; film 4 positions prevent pounding between the plane skylight at glass and LEXAN; its combination is to use tank bracket 5 clampings; plane skylight is in protective surface during use, and glass faces gunslinging face.

The structure of composition transparent anti-theft panel embodiment shown in Figure 3 is identical with Fig. 2, and its combination is to use mechanical clamp 6 to connect with screw 7 and fixes.

Anti-pound between plane skylight and the glass of described polycarbonate LEXAN can be gapped or do not have the gap when the utility model was implemented, and its bulletproof effect is identical.
