Abstract
The violence-proof and fire-proof alarm glass consists of several layers of common glass, photoconductive fibre, polyvinyl butyral layer and hydrated sodium silicate, and it has high transparency, no reflective scattering and good fireproof property. During its production, glass layers, polyvinyl butyral layer and photoconductive fibre are first composited at 1.0-1.2 Mpa and 120 deg.C, and the composite glass is then composited with another glass layer and hydrated sodium silicate sandwiched in between and dried naturally. The test shows that the glass can't be penetrated by bullet and has a fireproof period of 0.82-0.85 hr.
Description
The present invention relates to anti-violence and fire-proof alarm glass and method for making thereof, particularly with anti-violence and fire-proof alarm glass and the method for making thereof of photoconductive fiber as lead.
As everyone knows, splinter-proof glass comes out already, is more than three layers between simple glass at first, fills out macromolecular material as tackiness agent, and this kind tackiness agent has good cohesive force and elasticity, penetrates so can hinder the group bullet.Be placed in the binder layer the netted Stainless Steel Wire of 0.2-0.4 millimeter between glass and make lead and can report to the police and strengthen its anti-impact force though have recently to be reported in, as the prompting of CN2219780Y, its shortcoming is after adding netted Stainless Steel Wire, because reflection action has been disturbed people's sight, particularly as glass for vehicle window, to cause the interference of very big sight line to the driver, therefore failing to be promoted application, secondly is that resistivity against fire is poor, and this also is to limit another factor that it can't be implemented.
The object of the present invention is to provide a kind of anti-violence and fire-proof alarm glass, it is to make lead with photoconductive fiber, its transparency is the same with simple glass, interlayer does not have wire, so the interference of no-reflection scattering is particularly suitable for doing the military vehicle glass for vehicle window, the anti-riot glass of sedan limousine, fair hall, the shatter proof glass of financial machinery etc.
Embodiment of the present invention are as follows: it is by multilayer simple glass layer, polyvinyl butyral acetal (PVB) bonding coat, and photoconductive fiber, hydrated sodium silicate flame retardant coating are formed, and wherein said photoconductive fiber layer adopts the silica-type of mineral-type, silicon carbide type; The tetrafluoroethylene type of organic polymer class, polyester type, described flame retardant coating is to adopt hydrated sodium silicate, two interlayers are flame retardant coatings in the described multilayer simple glass, between all the other per two layers of simple glasses is the polyvinyl butyral acetal bonding coat, photoconductive fiber can be in any bonding coat or flame retardant coating, and goes out the two ends lead cruelly.
Its method for making is:
To spread the PVB film between the multilayer simple glass, wherein except that adding the PVB film, put the photoconductive fiber of one deck trellis in the 1.2nd layer of simple glass again, at 2-4 hour, 1.0 * 10
6-1.2 * 10
6Under the handkerchief pressure and under 120 ± 5 ℃ the temperature, heating pressurization forms and contains fibre-optic composite intermediate layer glass; Form anti-violence and fire-proof alarm glass of the present invention with adding the last layer hydrated sodium silicate between this composite intermediate layer glass and one deck simple glass, drying naturally then.
In the anti-violence and fire-proof alarm glass of the present invention because to add this fiber of photoconductive fiber be clear, colorless, so it almost is the same making the simple glass of its transparency of glass of the present invention and suitable thickness, do not occur sunken the lacking that CN2219780Y adds like that has reflective scattering to interrupt the view behind the netted Stainless Steel Wire of 0.2-0.4 millimeter extremely, this is a maximum feature of the present invention.
Secondly after the present invention added the hydrated sodium silicate layer, it was a kind of fire prevention intumescent material, and this also is one of feature of the present invention for the fire-resistant sound insulation.
Therefore; the multi-functional anti-violence and fire-proof alarm glass of functions such as that glass of the present invention integrates is shellproof, warning, fire prevention, sound insulation; be to be applicable to all kinds of sales counters; military vehicle, high-up's safety vehicle window, exhibition show window and large-area glass curtain wall; can be government bodies, places such as banking and insurance business, jewelry gold row, famous and precious article exhibition, financial settlement provide safe and reliable protection.
Following preference is described in detail the present invention in conjunction with the accompanying drawings, but does not mean that the restriction scope of the invention.
Embodiment 1, with 3 blocks of thick glass of 5 millimeters (1), after being placed on operator's console, put a slice thickness between per two sheet glass and be 1 millimeter polyvinyl butyral acetal (PVB) film (2), wherein remove between two sheet glass to put and put one deck again behind the PVB and be the mineral-type silicon-dioxide photoconductive fiber (3) of trellis and expose these fibre-optic two terminal wire in order to being connected, then 1.1 * 10 with warning device
6The handkerchief pressure and temp is to heat to form in 3 hours under 125 ± 3 ℃ to contain fibre-optic composite intermediate layer glass, between this composite intermediate layer glass and other 1 thickness also are 5 millimeters simple glass, add 1 mm thick hydrated sodium silicate flame retardant coating (4) more then, dry naturally and form transparent anti-violence and fire-proof alarm glass (consulting Fig. 1) of the present invention and do following test.
Two photoconductive fiber end lines that above-mentioned anti-violence and fire-proof alarm glass is exposed are connected with alarm control system, and 5 meters shootings at a distance, bullet is apart from 100 millimeters with " the May 4th " pistol, and three bullets all do not penetrate, and warning is in time sent light, sound signal.
To fire testing is to adopt national standard, and its fire resistance period is 0.82 hour.
Embodiment 5, remove silicon-dioxide photoconductive fiber (3) is placed on hydrated sodium silicate flame retardant coating (4) at home and abroad the transparent glass that all the other conditions and example 1 identical Fig. 2 of consulting make, do shellproof test, three bullets do not penetrate yet, and in time send light and sound signal, and fire resistance period is 0.84 hour.
Comparative example 1 will be in above-mentioned per two layers of simple glass adds the binder layer of polyvinyl butyral, and wherein one deck adds 0.3 millimeter netted Stainless Steel Wire and makes Bullet-proof alarm glass, because wire is arranged, in the sun, reflective scattering is arranged seriously, fire resistance period is 0.72 hour altogether.
Advantage of the present invention is as follows:
1, the high glass identical with thickness of transparency is the same, the no-reflection scattering, and fire resistance period is long.
2, method for making is simple, and reliable, various optical fibers all can be suitable for.
3, thickness of glass, the thickness of bondline thickness and flame retardant coating can come to select as requested.
Fig. 1 is the anti-violence and fire-proof alarm glass cross-sectional of photoconductive fiber in the polyvinyl butyral acetal layer.
Fig. 2 is the anti-violence and fire-proof alarm glass cross-sectional of photoconductive fiber in the hydrated sodium silicate layer.
Wherein 1 is that simple glass 2 is polyvinyl butyral acetal bonding coats
The 3rd, photoconductive fiber 4 is hydrated sodium silicate flame retardant coatings
