Abstract
The utility model relates to a bullet proof glass for a pistol, which comprises three layers of float glass. A layer of the PVB rubber sheet is arranged between two adjacent layers of glass. In the technical proposal, the bullet proof glass for the sniping rifle can effectively prevent the penetration of a 54-model pistol and avoid the scrap dropping of the rear surface. In addition, the bullet proof glass for the piston has the advantages of simple structure, good reliability, and smaller thickness compared with like products.
Description
Technical field
The utility model belongs to glass deep processing field, particularly relates to a kind of pistol splinter-proof glass.
Background technology
Laminated glass claims doubling glass again, and pressing from both sides one deck exactly between two blocks of glass is the PVB intermediate coat of main component with the polyvinyl butyral acetal.Even glass is cracked, fragment also can be bonded on the film, and broken glass surface still keeps neatly smooth.This stabs and penetrates the generation of fall event with regard to effectively having prevented fragment, has guaranteed personnel safety.Common laminated glass is because thickness is less, and intensity is little, does not have to resist the performance that bullet penetrates.And splinter-proof glass can overcome the defective of common laminated glass.It is a kind of that splinter-proof glass is actually laminated glass, and it is by multiple glazing and film is superimposed makes, and generally more than 20mm, the splinter-proof glass total thickness of having relatively high expectations can reach more than the 50mm total thickness.
The effect safe in utilization of splinter-proof glass mainly contains two judging criterions:
The first, bullet must not run through, and protects effect if bullet is worn out after promptly having lost screen;
The second, back side glass can not fall quarrel, because splashing of broken quarrel also may injure the person.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of pistol splinter-proof glass, can effectively stop 5-4 type pistol to the running through of glass, and back side glass does not fall quarrel.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of pistol splinter-proof glass includes three layers of float glass, all is provided with one deck PVB film between the adjacent two layers glass.
As preferably, the thickness of layer glass up and down in three layers of above-mentioned float glass is 5mm, and middle one deck thickness of glass is 10mm.
As preferably, above-mentioned two-layer PVB film thickness is 1.14mm.
Three layers of above-mentioned float glass are toughened glass.
The bulletproof effect of splinter-proof glass is relevant with following textural factor:
1) total thickness of splinter-proof glass is directly proportional with bulletproof effect; Total thickness of the present utility model is 22.28mm.
2) the film thickness in the splinter-proof glass structure is relevant with bulletproof effect; 1.14mm the film bulletproof effect is better than using the splinter-proof glass of 0.76mm film;
The utility model has been owing to adopted above technical scheme, and this pistol splinter-proof glass can effectively stop 5-4 type pistol to the running through of glass, and back side glass does not fall quarrel.Other has simple in structure, good reliability, compares advantages such as like product thickness is thinner.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of pistol splinter-proof glass as shown in Figure 1 includes three layers of float glass 2, all is provided with one deck PVB film 1 between the adjacent two layers glass; Layer glass thickness is 5mm about in three layers of above-mentioned float glass 2, and middle one deck thickness of glass is 10mm; Above-mentioned two-layer PVB film thickness is 1.14mm.
During manufacturing, at first original sheet glass is cut by desired size, edging angle then, and clean and dry.Preparation thickness is the PVB film of 1.14mm (using 0.76mm+0.38mm), the glass of cleaning-drying sent into close the sheet chamber, it is superimposed to glass and PVB film to press the 5mm+1.14mmPVB+10mm+1.14mmPVB+5mm structure, and the superimposed difference of last lower glass plate is no more than 1.5mm.Hot-rolling pressure gas then, this process flow is as follows, preheating---first pressure roller---heating chamber---, second pressure roller, after the preheating, the glass surface temperature should be at 25 ℃～30 ℃, and distance is set to than the little 1mm of laminated glass total thickness between the first pressure roller up-down rollers, and pressure is 0.2～0.5MPa; Before entering second pressure roller, the glass surface temperature should be at 70 ℃ ± 10 ℃, and distance is set to than the little 2mm of laminated glass total thickness between the last lower compression roller, and pressure is 0.3～0.5MPa.Send into autoclave after pressing, the pressurization of heating simultaneously, top temperature is set to 135～140 ℃, and peak pressure is set to 13kg/cm
2, temperature reaches and begins insulation behind the maximum, half an hour to one time hour.Stop heating, treat to stop after the autoclave internal temperature is reduced to below 50 ℃ pressurization, treat to get product after glass cools off fully.
Claims (4)
1. a pistol splinter-proof glass is characterized in that, includes three layers of float glass (2), all is provided with one deck PVB film (1) between the adjacent two layers glass.
2. a kind of pistol splinter-proof glass according to claim 1 is characterized in that, the inside and outside layer glass thickness in described three layers of float glass (2) is 5mm, and middle one deck thickness of glass is 10mm.
3. a kind of pistol splinter-proof glass according to claim 1 is characterized in that, described two-layer PVB film (1) thickness is 1.14mm.
4. a kind of pistol splinter-proof glass according to claim 1 is characterized in that described three layers of float glass (2) are toughened glass.
