Abstract
The utility model provides intelligent dimming type bullet-proof glass. The intelligent dimming type bullet-proof glass comprises a glass surface layer, a PVB (Poly Vinyl Butyral) film layer, a laminated glass layer, another PVB film layer and a glass bottom layer. The intelligent dimming type bullet-proof glass is structurally characterized in that another PVB film layer and a liquid crystal film layer are also formed between the laminated glass layer and the PVB film layer; and the liquid crystal film layer is electrically connected with an outside power supply. According to the intelligent dimming type bullet-proof glass, one more liquid crystal film layer is formed on the left side or the right side of the laminated glass layer of the bullet-proof glass, so that the dimming function of the bullet-proof glass can be realized based on the inherent characteristic that the liquid crystal film layer can be switched between the transparent state and the nontransparent state after being electrified, and the benefit is provided for expanding the applicable range of the conventional burglar-proof glass.
Description
Technical field
The utility model relates to a kind of bulletproof glass.
Background technology
Existing bulletproof glass is observed from section, its structure successively by glassy layer, PVB(namely: polyvinyl butyral resin) rete, glassy layer, PVB rete and glassy layer consist of.In fact, bulletproof glass is bonded together multi-disc glass or high strength organic board by the transparent adhesive tape condensation material and makes.It generally has following three-decker: 1, bearing layer: at first this layer withstands shocks and breaks, and generally adopts the glass that thickness is large, intensity is high, can destroy bullet or change warhead form, makes it lose the ability that moves on.2, transition zone: generally adopt the organic gel condensation material, bonding force is strong, light resistance good, and energy absorption portion impact energy changes the bullet direction of advance.The very solid and transparent chemical film of folder one deck in laminated glass.This can not only prevent cartridge shooting effectively, but also the performances such as crackle also do not occur after having antisurge impact, antiknock, antidetonation and shock.3, safe protective covering: this one deck adopts high strength glass or high-strength transparent organic material, and elasticity and toughness are preferably arranged, and can absorb most impact energys, and guarantees that bullet can not pass this layer.Can say, the appearance of bulletproof glass has been made very large contribution for social development really,
But, also there is following deficiency in actual applications in existing bulletproof glass: can not light modulation, that is: moment changes the transparency of bulletproof glass, this has very important significance to some occasion, and even life-and-death matter, for example the armed impact of bandit bank, bank clerk and its glassy phase every the time, if moment changes the glass transparent degree, just can effectively avoid the casualties that causes because of close range shooting, also be conducive to guarantee the safety of national wealth.
Summary of the invention
For overcoming the prior art above shortcomings, the utility model aims to provide a kind of intelligent dimming bulletproof glass, and this bulletproof glass is guaranteeing on the basis of original performance also have the function of moment adjustment transparency, therefore, be conducive to enlarge the scope of application of existing burglar-proof glazing.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this intelligent dimming bulletproof glass, comprise glass surface layer, PVB rete, laminated glass layer, PVB rete and glass bottom, it is characterized in that: also have a PVB rete and a liquid crystal rete between described laminated glass layer and PVB rete, this liquid crystal rete is electrically connected to extraneous power supply.
During as preferred concrete enforcement, the thickness of described glass surface layer, PVB rete, laminated glass layer, PVB rete, PVB rete and glass bottom is respectively 8mm, 0.76mm, 8mm, 0.76mm, 0.76mm and 8mm.
Beneficial effect: compared with prior art, after the utility model is set up PVB rete and liquid crystal rete, utilize the liquid crystal rete energising variation characteristic of intrinsic transparent and opaque state afterwards, realized the dimming function of burglar-proof glazing, be conducive to enlarge the scope of application of existing burglar-proof glazing.
Description of drawings
Fig. 1 is the schematic construction key diagram of an embodiment of the utility model.
In figure: glass surface layer 1, PVB rete 2, laminated glass layer 3, liquid crystal rete 4, PVB rete 5, glass bottom 6.
The specific embodiment
Referring to Fig. 1.According to glass surface layer 1, PVB rete 2, laminated glass layer 3, PVB rete 7, liquid crystal rete 4, after PVB rete 5 and glass bottom 6 are stacked, make under the high-temperature high-pressure craft condition.During concrete enforcement, glass surface layer 1, PVB rete 2, laminated glass layer 3, PVB rete 7, liquid crystal rete 4, the thickness of PVB rete 5 and glass bottom 6 can be respectively 8mm, 0.76mm, 8mm, 0.76mm, 0.76mm and 8mm.
