Description

A kind of aperture half mirror

Technical field

The utility model is related to half mirror technical field, more particularly to a kind of aperture half mirror.

Background technology

Half mirror is (also known as：Atom mirror, single-surface mirror, single anti-glass, Double sided mirror, one-way glass), it is that one kind pair can See that light has the glass of very high reflectance.Reflecting surface (minute surface) must be side to light or towards room to half mirror when in use Outer side.When outdoor is than indoor become clear, half mirror is similar to general mirror, and the scenery of interior be can't see in outdoor, but Interior can see the scenery of outdoor clearly.Half mirror is primarily adapted for use in disguised observation window, hole etc..Front is glass mirror Face, for reflection light, during installation should just facing to monitored room (：Where the space to be observed, such as suspect Space.

Wire glass is through special to process obtain a kind of compound by glass (or lucite) and high-quality engineering plastics Material, it is typically transparent material, and for example (it is lexan that generally power shows resin to PVB/ polycarbonates thermoplastic Resin is also LEXAN PC RESIN).It has outward appearance and the behavior of transmission light of simple glass, and the shooting to miniweapon is carried For certain protection.Safety glass is a kind of prestressed glass, to improve the intensity of glass, usually using side chemically or physically Method, in glass surface formation compression, glass bears to offset skin stress first during external force, so as to improve bearing capacity, increases Strong glass itself anti-wind pressure, cold and heat, impact etc..Safety glass and wire glass belong to safety glass.

Half mirror, which is widely applied, to be needed to protect the outdoor window of privacy, is also having hearing room, bank etc. to need safety The higher place of property.But, product generally existing glass body in the market can not meet the infringement of higher level (for example Gunslinging), also there is portion of techniques to be used in combination with safety glass with half mirror, improve the shock resistance of glass. But it is due to the film plating layer of the superposition and half mirror of compound glass in itself, the lighting performance of interior will be influenceed, and Existing glass is high to 450 to the light of 550nm wave bands transmissivity, and adhesive or anti-is particularly being used in compound glass During oxidant, it is easy to which it is green to make transmitted light, influences indoor observation effect.

In view of the above-mentioned problems, proposing the utility model.

Utility model content

The purpose of this utility model is to provide a kind of aperture half mirror.

To realize above-mentioned utility model purpose, the technical solution of the utility model is：A kind of aperture half mirror, bag Include the first glass basis 1, the lower surface of the first glass basis 1 be sequentially provided with from inside to outside light absorbing layer 2, metal absorption layer 3 and Metallic reflector 4, metallic reflector 4 is provided with loophole 7, and the ecto-entad of loophole 7 penetrates metal absorption layer 3, light absorbing layer 3 To the lower surface of the first glass basis 1, the outside of metallic reflector 4 is provided with the second glass basis 6, the outside of metallic reflector 4 Adhesion-molded by PVB films 5 between the second glass basis 6, metal absorption layer 3 is layers of copper.

Further, the second glass basis 6 is wire glass or safety glass.

Further, a diameter of 0.5-5mm of loophole 7, the nearest distance in the adjacent edge of loophole 7 is 0.5-5mm.

Further, metallic reflector 4 is any one layer in Ag layers, Al layers, Cr layers, and thickness is 10nm~30nm.

Further, light absorbing layer 2 be SSTN layer, any one layer in TiN layer, thickness is 10nm~30nm.

Further, metallic reflector 4, metal absorption layer 3 and light absorbing layer 2 are vacuum magnetic control cathodic spattering layer.

The beneficial effects of the utility model are：

The utility model is applied to outdoor window, and the one side of wire glass or safety glass is arranged on outside, in face of danger Region, thus it is overall with bulletproof function, physics strike, especially closely gunslinging, blast can be subjected to, and be provided with metal Absorbed layer layers of copper, it is non-colored light to make through light, is also further provided with loophole, adds the daylighting effect of interior.

Embodiment

Below in conjunction with accompanying drawing to the utility model, the technical scheme in the utility model embodiment is carried out clear, complete Site preparation is described.

As shown in figure 1, a kind of aperture half mirror, is primarily adapted for use in outdoor window.The first glass is used as with simple glass Glass matrix, wire glass or safety glass are as the second glass basis, and the second glass basis one side is mounted externally during installation. The first lower surface in the first glass basis plates one layer SSTN layers with vacuum magnetic control cathodic sputtering or TiN layer is used as light absorbing layer, thick Spend for 10-30nm, the light absorbing layer of this thickness can make light in its surface refraction, reduce its reflection increase its absorption, it is ensured that Transparent effect is more preferable；Then the outside of light absorbing layer sputters one layer of layers of copper again again, it is ensured that the glass is to 450 to 550nm wave bands Light transmissivity it is identical with the transmissivity of the light of its all band, make this through the light color of glass to be colourless；Then Layer of metal reflecting layer is sputtered again in the outside of metal absorption layer layers of copper, any layer in preferred Ag layers, Al layers here, Cr layers, Thickness is 10-30nm, for reflection room UV light, and the light of reflection can interfere the vision of outdoor people, it is impossible to see interior clearly Image, plays the effect of protection privacy；Then uniform on metallic reflector to etch circular hole, etching depth penetrates Metal absorption Layer and light absorbing layer are to the lower surface of the first glass basis, a diameter of 0.5-5nm of the circular hole of etching, and the edge of adjacent circular holes is most Near distance be 0.5-5nm, Fig. 2 be glass from safety glass unilateral observation to floor map, due to the setting of circular hole, make A part of light is got in through glass, can increase the daylighting effect of interior；Finally with PVB films in metallic reflector The second glass basis is fixed in outside, here preferred wire glass or safety glass, and the second glass basis has towards sightingpiston Bulletproof function, can be subjected to physics strike, especially closely gunslinging, blast, and film plating layer is fixed on two by PVB films In the middle of block glass, it can effectively prevent film plating layer from coming off and scratching.

In summary, the utility model is applied to outdoor window, and the one side of wire glass or safety glass is arranged on outside, In face of danger zone, therefore entirety has bulletproof function, can be subjected to physics strike, and especially closely gunslinging is exploded, and Provided with metal absorption layer layers of copper, it is non-colored light to make through light, is also further provided with loophole, adds the daylighting effect of interior Really.

This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but As long as all being protected in right of the present utility model by Patent Law.
