Abstract
The invention discloses a piece of tough and invisible bullet-proof glass which comprises a bearing layer, a bullet-proof layer and an outer protecting layer which are adhered from inside to outside in sequence, wherein a layer of liquid crystal dimming membrane is added between the bullet-proof layer and the outer protecting layer; the bullet-proof layer is made of polyethylene glycol terephthalate layer; the outer protecting layer is a glass fiber layer; the thickness of the bullet-proof glass is within 3-8mm. The tough and invisible bullet-proof glass disclosed by the invention is very high in stability and high-strength high breakage toughness, and can be widely applied to bullet-proof transparent window of aircrafts and ground vehicles.
Description
Technical field
The present invention relates to field of new, be specifically related to a kind of bulletproof glass of tough stealth.
Background technology
bulletproof glass be a kind of can under the bomb blast of certain equivalent be attacked, glass does not depart from framework, remains intact or a kind of special glass of high safety performance that non-penetrative destroys.Bulletproof glass is a kind of compound material obtained through special processing by glass or lucite and high-quality engineering plastics, and it is transparent material normally, comprises polycarbonate layer and is clipped among simple glass layer.There is the outward appearance of simple glass and transmit the performance of light, having protective effect to the attack of hard material.
Seem maximum bulletproof glasses on the market at present, its structure is mainly divided into two kinds: compound glass and one deck carbonic ester plate utilize PETG layer film and polyurethane pellicle to be composited by the first, the bullet-proof of this bulletproof glass is good, but quality is generally heavier.Another kind is that compound glass and PETG layer film are composited, and this bulletproof glass quality is relatively light, but bulletproof effect is poor, and intensity is also lower.
Publication number is CN 2451329, and publication date is the bulletproof glass that the Chinese patent literature of 2001.10.03 discloses a kind of high strength, comprises three layers of float glass plate, is bonded with polyurethane film, polyurethane sheet outside three layers of float glass plate, and intennediate bond rupture pressure disc.Although this bulletproof glass increases in intensity, overall flexibility is poor.
Summary of the invention
The present invention aims to provide a kind of bulletproof glass of tough stealth, has the stability of high strength, high strength high-fracture toughness, and has stealthy effect.
The bulletproof glass of tough stealth of the present invention; comprise the bearing layer, burster course, the outer protective layer that bond successively from inside to outside; especially; one deck liquid crystal light modulation film is added between burster course and outer protective layer; described burster course is made up of PETG layer; described outer protective layer is glass layer, and the thickness of described bulletproof glass is between 3mm-8mm.
Need ben, it is seamless spliced that described liquid crystal light modulation film reaches 2000mm wide cut, and the transmitance of described liquid crystal light modulation film reaches more than 80%.
Preferably, described bearing layer is safety glass layer; Or another kind of embodiment, described bearing layer is made up of transparent glass-ceramics and rupture pressure disc layer, and wherein, the thickness of rupture pressure disc is between 0.3-1mm.
Preferably, the thickness of described glass layer is at 2-4mm.
Beneficial effect:
1. adopt transparent glass-ceramics as bearing layer, there is excellent thermal shock resistance and dimensional stability, adjustable at sizable temperature range thermal expansion coefficient, even can expand by set to zero; There is the stability of high strength, high strength high-fracture toughness;
2. special interpolation one deck liquid crystal light modulation film, makes this bulletproof glass except bulletproof function, also has stealthy effect;
3. lightweight, because the strength ratio silicate glass intensity of this transparent glass-ceramics is high, therefore in equal bulletproof ability situation, the bulletproof glass that the weight ratio of this bulletproof glass is made with common silicate glass lightweight;
4. can be widely used in the shellproof transparent window of aircraft and surface car.
