Abstract
The utility model discloses bullet-resisting glass, which comprises at least three glass substrates; a layer of perspex mebrane is arranged between two adjacent glass substrates; at least one layer of light-adjusting glass layer is arranged among a plurality of glass substrates; and the light-adjusting glass layer is composed of two layers of ITO glass and a polymer dispersed liquid crystal material which is solidified between the two layers of ITO glass. The bullet-resisting glass has the technical proposal that: the light-adjusting glass layer is added based on the prior bullet-resisting glass; thereby, the bullet-resisting glass is in opaque state in the normal condition, and the bullet-resisting glass can present the transparent state under the action of certain external voltage; so the transparent state can be rapidly switched into the opaque state. When meeting attack, the bullet-resisting glass can be rapidly switched into the opaque state, so as to shelter from attacker visual line and lead the attacker not to aim at the target; thus being effectively able to protect users life and property security.
Description
Technical field
The utility model belongs to glass processing and manufacturing field, is specifically related to a kind of splinter-proof glass that can light modulation.
Background technology
Splinter-proof glass is a kind of hi-tech glass that developed recently gets up, and because of its intensity is enough high, is enough to keep out penetrating of appropriate level bullet, obtains user's generally approval.But blemish in an otherwise perfect thing is, if suffer from than the higher cartridge shooting of himself shellproof rank, the perhaps repeatedly cartridge shooting of same position, splinter-proof glass unavoidably can be breakdown, and existing splinter-proof glass is transparent at any time, and the attacker can see the situation of the inside target fully from the outside, attacks targetedly, target also can't effectively be hidden, thereby threatens user's the security of the lives and property.
Summary of the invention
In order to solve above-mentioned technical problem; the purpose of this utility model provides a kind of splinter-proof glass; on the basis of existing splinter-proof glass, increase the dimming glass layer; thereby this splinter-proof glass is an opaque state under normal conditions, is vitreous state under certain impressed voltage effect; when running into attack; can switch to opaque state fast, block attacker's sight line, therefore can effectively protect user's security of the lives and property.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of splinter-proof glass, comprise triplex glass basic unit at least, layer of transparent plastic cement diaphragm is set between the adjacent two layers glass-base, having one deck in the described several layers glass-base at least is the dimming glass layer, and described dimming glass layer is made of two-layer ito glass and the polymer dispersion liquid crystal material that is solidificated between the two-layer ito glass.
For improving the deficiency of common splinter-proof glass; the utility model adopts two-layer ito glass as substrate; perfusion one layer of polymeric dispersed liquid crystal material between two-layer ito glass; make the dimming glass layer after solidifying; then that the dimming glass layer that makes and multi-layer planar glass and PVB (polyvinyl butyral acetal) film is superimposed; production technique by dry method laminated glass completes; because of the opaque state that is creamy white under the common state of polymer dispersion liquid crystal material; and under certain impressed voltage effect, be vitreous state; therefore; the quick switching of vitreous state and opaque state; and damage or splinter-proof glass when partly damaging at the impressed voltage circuit; still can be returned to opaque state, block attacker's sight line, therefore can effectively protect user's security of the lives and property.
Above-mentioned dimming glass layer is a upper layer.The dimming glass layer is located at the surface, makes that the bulletproof effect of splinter-proof glass is unaffected.
Above-mentioned polymer dispersion liquid crystal material is thermofixation, photocuring or electron beam curing liquid crystal material.
Above-mentioned clear plastics diaphragm is PVB film, EVA film or EN film.
The beneficial effects of the utility model are: even suffer from than the higher bullet of self shellproof rank; the utility model is because can " light modulation "; can switch to opaque state fast, block attacker's sight line, therefore can effectively protect user's security of the lives and property.
The utility model increases the dimming glass layer owing to adopted above technical scheme on the basis of existing splinter-proof glass, thereby, this splinter-proof glass is an opaque state under normal conditions, under certain impressed voltage effect, be vitreous state, like this, the quick switching of vitreous state and opaque state.Running into when attacking, splinter-proof glass can switch to opaque state fast, blocks attacker's sight line, makes it can't aimed objective, therefore can effectively protect user's security of the lives and property.

Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of splinter-proof glass as shown in Figure 1, comprise triplex glass basic unit, layer of transparent plastic cement diaphragm 4 is set between the adjacent two layers glass-base, wherein, surface one deck is the dimming glass layer, and all the other are two-layer to be sheet glass 3, and described dimming glass layer is made of two-layer ito glass 2 and the polymer dispersion liquid crystal material 1 that is solidificated between the two-layer ito glass.
Present embodiment is the pistol splinter-proof glass, and making processes is as follows:
The thick ito glass of two-layer 5mm and ito surface between apply the one layer of polymeric dispersed liquid crystal material.Solidify back and two-layer sheet glass (thickness is respectively 10mm, 5mm), the thick PVB film order of two-layer 1.14mm is superimposed, enters the hot pressing chamber then.The hot pressing chamber is divided into three zones, and the first area is the preheating zone, and temperature is 60 ℃, 3 minutes time; Second area is a precompressed zone, and temperature is 120 ℃, and 10 minutes time, the spacing of every pair of press bonding roller deducts 2mm for the glass total thickness; The 3rd zone is the pressing district, and temperature is 200 ℃, and 5 minutes time, the spacing of every pair of press bonding roller deducts 4mm for the glass total thickness.Because temperature, time are relevant with thickness of glass with the press bonding roller spacing, should change parameter according to thickness of glass in actual production.After pressing, glass sends into autoclave, the pressurization that under closed state, heats up, and temperature rise rate is 3 ℃ of per minutes, compression rate is per minute 500 kilogram forces/m
2, i.e. per minute 500 pascals, the temperature maximum is set at 130 ℃, and the pressure maximum value is set at 1 * 10
5Pascal kept 30 minutes under top temperature and maximum pressure conditions, and the pressurization that stops to heat obtains finished product behind the furnace cooling.
Embodiment 2:
A kind of splinter-proof glass as shown in Figure 2, comprise six layers of glass-base, layer of transparent plastic cement diaphragm 4 is set between the adjacent two layers glass-base, wherein, surface one deck is the dimming glass layer, and all the other five layers is sheet glass 3, and described dimming glass layer is made of two-layer ito glass 2 and the polymer dispersion liquid crystal material 1 that is solidificated between the two-layer ito glass.
Present embodiment is the sniper rifle splinter-proof glass, and making processes is as follows:
