Description

Bullet resistant glass
The present invention relates to the improvement of bulletproof glass screen, particularly be applied to the purposes of ensuring public security.
Bulletproof glass generally is the laminated thing through the heat-treatment of annealing glass plate of thickness 10-12 millimeter.For example, make last laminated thing by four layers of this special glass.The result makes thickness reach the 40-50 millimeter.Like this, this laminated thing is very expensive, is difficult to machining, and is also very heavy during use.
The category of glass structure that other anti-emission bullet impacts sees GeneralElectric Company BP 2098650 and USP4774143.The category of glass structure that this BP is introduced has a back of the body composite bed, it comprises Merlon, glass or the entity resin-like material of multilayer, wherein to have one deck at least be Merlon, also have a face composite bed, this is to be composited by compound glass, comprise surface layer and nexine, every layer thickness is the 0.76-5.59 millimeter, also has an intermediate core layer, and this sandwich layer is all thicker than surface layer and nexine.This sandwich layer can be again an individual layer, also can be that MULTILAYER COMPOSITE forms, and thickness is the 5.59-25.4 millimeter preferably.
This United States Patent (USP) has been introduced a kind of transparent laminated windowpane structure, the continuous internal layer of making comprising thermoplastic, and parallel with internal layer basically skin,, fill out with adhesive material by that separate, spaced glass interval comprising at least one at adjacent two sections interval.Also can comprise an elastomeric material that is squeezed between internal layer and the skin in this kind window construction, in order to limit the gap between each layer.Because this window construction is made up of multistage, an emission bullet can only break that section, and can not make the adjacent segment that separates in same cracked, makes to be subjected to launching the fair visibility that still keeps window construction after bullet impacts.These glass segments itself are to be made of laminated glass, and therefore this complex structure is thick and heavy.
Above-mentioned two prior arts all propose the structure of front panel, are by several layers of laminated the forming of glass, become the feature of " bulletproof glass ".These two prior arts all be in front the layer and backing layer between used the air gap.In this BP, the effect of this air gap just helps to improve the optical characteristics of double-layer glass structure.In this United States Patent (USP), mention this air gap for this invention and non-key, just meet and be subjected to the hot-cool environment of alternation and may make and just use this gap when between the surface layer of structure and the back layer warpage taking place at window construction.
More than the manufacturing of these two kinds of structures all too complicated, can not make at the construction field (site), and weight is big, high price.
The objective of the invention is to overcome the shortcoming in the aforementioned prior art or improved at least substantially, bulletproof glass screen provided by the invention is to be made of compound glass, each layer glass plate has the front and back, and on each face, apply the anti-security personnel's of pulverizing rete, make every glass sheets have film, become laminated thing, with certain interval each laminated thing and adjacent laminated thing are separated, and fill with air in the gap of adjacent laminated thing.
For example a kind of polyester security personnel of operable type of film film is to be provided and the anti-rete of pulverizing of conduct by 3M company (Minnesota, Mining and Manufac-turing Company).This film is to be applied on the face of glass sheet, prevents that sheet glass from pulverizing and glass fragment disperses.Contact adhesive by the water activation is arranged on this film, make it to be adhered to glass surface.
The ensure public security schematic diagram of the first half of screen of the present invention of being shown in Figure 1.Lower Half and its symmetry are not shown also bright.
As shown in Figure 1, security personnel's screen 1 comprises one group 4 layers window glass plate 2,3,4,5, and they are separated by 6,7,8 in gap respectively.
For the convenience that illustrates, it is the front of screen 1 that glass plate 2 is used as.
This 4 laminate sheet the 2,3,4, the 5th, by framework 9 that they are spaced apart and fix.Framework 9 can be any suitable structure, and uses industry material commonly used to make, and as the metal extrudate, timber is moldable.
All apply the anti-rete 10 of pulverizing on the two sides of plate 2,3,4,5.Space 6,7,8 between plate 2,3,4,5 fills air.
On the face of plate 2,3,4,5, apply rete 10 by the anti-common mode of pulverizing film of the type.As mentioned above, this is a kind of polyester film that has water activation contact adhesive.Glass sheet 2,3,4,5 can be the normal formula window glass.
For the embodiment of pressing Fig. 1, several tests have been carried out with 0.22 high speed rifle.
In test for the first time, use 5 millimeters fixing glass sheet, its gap is 3.175 millimeters.The anti-film of pulverizing of the polyester that uses 3M to provide, its thickness is 0.18 millimeter.In this glass screen previous crops single shot, make front panel 2 broken opening, but do not penetrate film 10. second layer glass sheets that pasted this plate back, promptly 3 of Fig. 1 also break, supposition is owing to impact due to the shock wave of being dispersed.
In test for the second time, use the used screen board of the similar test first time, difference is to use the glass sheet of 4 millimeters of thickness instead.Several have been shot.First result is similar with testing for the first time.Second makes triplex glass, and promptly 4 of Fig. 1 are broken, the 3rd just four-layer glass be that 5 of Fig. 1 is broken, but bullet does not penetrate this layer glass.
The laminated thing of used glass-polyester film is a kind of composite structure, is increased the tensile strength of this glass sheet itself by this film.In other words, this structure can be deformed to more (absorbing more kinetic energy) and breaks just now.The kinetic energy that is absorbed is many more, and the company degree of bullet after breaking this sheet glass is just slow more.
The emission bullet of launching from firearm reaches the supersonic speed that produces shock wave.Therefore, since emission kinetic energy of bullet and the energy that shock wave is followed glass sheet is destroyed.The present invention is not said that self-evident is that these energy are to be absorbed effectively by this compound glass in two ways.By means of the tensile strength that increases glass sheet, make every layer of kinetic energy that can more effectively absorb the emission bullet.Security personnel's film is glued fast to the one or both sides of glass sheet.The air gap between each plate is to be used to dissipate the energy of shock wave.The present invention combines this two aspect and a kind of effective bullet-proof screen is provided.
Show that for the assembly testing that pastes polyester film at each face of glass sheet along with the interval between every laminate sheet is strengthened, vandal-proof performance increases.Supposition is because the event that dissipates in the air gap of shock wave between each sheet.
According to the requirement of given purposes, can adopt the glass sheet of 2-12 millimeter thickness and the air gap that thickness is the 1-100 millimeter to form bullet-proof screen.For concrete bullet-proof screen, sheet and therebetween the gap can need the sheet number of institute's energy usefulness and change by bullet-proof screen.
Be applicable to that there are DTI (Deposition Technology Industries) and Martin ' s Processing (Australia) Pty.Ltd. in other security personnel's film manufacturer of the present invention, the registration mark that they sell security personnel's film is PROFILON.
Therefore, bullet-proof screen provided by the invention can be applicable to the security personnel's cell such as the teller, and other device is such as the device that also requires sight line except that requiring to ensure public security.Can be assembled at the scene by common glazing worker's general technology by the present invention, cutting this glass plate does not need special tool(s).Mode is that the anti-film of pulverizing is applied up in manufactory easily, saves this step when assembling security personnel screen.But be not to do like this.
Though the invention has been described by preferred version above, not saying self-evident is that the present invention also can be worked up other scheme by those of ordinary skills' knowledge, and for example, this security personnel's screen can be according to purposes and by constituting to layer glass less.In addition, though preferred version is to stick security personnel's film on the two sides of every layer of glass, also pad pasting on a face only.Equally, also can be to outermost layer glass only at the inner surface pad pasting, facing on the outer face does not have film.In such scheme, also can use the glass of other thickness, or form by each layer glass combination of different-thickness.
