Description
Technical field
The utility model is related to dimming glass technical field, more particularly to a kind of positive throwing dimming glass.
Background technology
Dimming glass be it is a light modulation film is combined into the middle of layer glass, through HTHP it is glued after integrally formed folder
The new special photoelectric glass product of Rotating fields.User by the break-make of control electric current whether control glass it is transparent with it is impermeable
Bright state.Glass not only has the characteristic of all safety glasses in itself, while being protected but also with control glass transparent whether privacy
Protective function, due to the characteristic of light modulation film interlayer, dimming glass is pellucidity when energized, is used as simple glass；When disconnected
Dimming glass is opaque state when electric, can be used as projection screen, substitutes common curtain.
But the dimming glass of glass curtain is used as in the market, because light modulation film also can in the event of a power failure
Have some light transmission so that the picture of display is not thrown clearly, also have portion of techniques by dimming glass one layer of glass therein more
The eyeglass with reflecting effect is changed to, to improve the definition of display picture, but this will produce mirror-reflection, in projection
Produce glare phenomenon.
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 positive throwing dimming glass.
To realize above-mentioned utility model purpose, the technical solution of the utility model is：A kind of positive throwing dimming glass, including the
One glass basis 1, the lower surface of the first glass basis 1 is provided with frosted texture or corrosion texture, and the lower surface of glass basis 1 is also
Provided with metallic reflector 2, the outside of metallic reflector 2 is provided with light modulation film layer 3, and the outside of light modulation film layer 3 is provided with the second glass base
Body 4, it is adhesion-molded by PVB films 5 between metallic reflector 2 and light modulation film layer 3, between the light modulation glass basis 4 of film layer 3 and second
It is adhesion-molded by PVB films 5.
Further, it is additionally provided with and silicon dioxide layer between the lower surface and metallic reflector 2 of the first glass basis 1.
Further, metallic reflector 2 is any layer in layers of chrome, layers of copper, silver layer or titanium layer.
Further, the thickness of metallic reflector 2 is 10-30nm.
The beneficial effects of the utility model are：
The positive back glass plate for throwing dimming glass is set to the coated glass with diffusing reflection effect by the utility model, so
When dimming glass as glass curtain makes picture apparent in use, the coated glass at the back side will be seen that light is reflected back, and
And due to diffusing reflection effect is presented, eliminate glare phenomenon.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by referring to following detailed description, it can more completely more fully understand that this practicality is new
Type and easily learn the adjoint advantage of many of which, but accompanying drawing described herein be used for providing to it is of the present utility model enter one
Step understands, constitutes a part of the present utility model, and schematic description and description of the present utility model is used to explain this practicality
It is new, do not constitute to improper restriction of the present utility model, wherein：
Fig. 1 is a kind of positive structural representation for throwing dimming glass of the utility model；
In figure：The glass basis of 1- first, 2- metallic reflectors, 3- light modulation film layers, the glass basis of 4- second, 5-PVB films.
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.
A kind of positive throwing dimming glass, including the first glass basis 1, the lower surface of the first glass basis 1 are provided with frosted texture
Or corrosion texture, layer of silicon dioxide layer is first plated on the surface of texture, because the adhesive force of silicon dioxide layer and glass is more preferable,
Be conducive to the sputtering in subsequent metal reflecting layer；Then in the outside of silicon dioxide layer by magnetron sputtering method metallized reflective layer 2,
Metallic reflector 2 can be any layer in layers of chrome, layers of copper, silver layer or titanium layer, here preferred silver layer, the thickness of metallic reflector
Control is in 10-30nm, and a part of visible ray is reflected back by metallic reflector, makes the picture of projection apparent；Metal is anti-
The outside for penetrating layer 2 bonds one layer of light modulation film layer 3 by PVB films, and the outside for dimming film layer 3 bonds second by PVB films again
Glass basis 4, the second glass basis 4 can select ordinary plate glass.
When preparing light modulation film, respectively put on one layer of conductive layer, each layer of conductive layer in each apply in two sides of light modulation film in advance
Put a metal foil.Here the conductive layer (ITO) that selective oxidation tin indium is prepared by sputtering method, 20~50nm of thickness, resistivity 80
~250 Ω m.Welding positive and negative polarity wire is connected with peripheral control unit in the metal foil that upper and lower two conductive layers are drawn, outside
Controller connects civilian power supply, can control liquid crystal layer current switching.
When energized, dimming glass curtain is changed into opaque state, can be used as positive glass curtain of throwing, and due to
The back side is coated with metallic reflector glass, it is seen that light, which is reflected back, makes picture apparent, and due in projection, on glass
Texture eliminates mirror-reflection, without glare phenomenon；When power is off, dimming glass curtain can make as translucent frosted glass
With.
In summary, the positive back glass plate for throwing dimming glass is set to the plated film with diffusing reflection effect by the utility model
Glass, so when dimming glass as glass curtain in use, the coated glass at the back side, which will be seen that light is reflected back, makes picture
It is apparent, and due to diffusing reflection effect is presented, eliminate glare phenomenon.
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.
