Description
Technical field
The utility model is related to glass technology field, more particularly to a kind of photochromic dimming glass.
Background technology
Photochromic glass is a kind of new energy-saving glass, and glass gradually tarnishes when illumination strengthens, reduce light and
It carries the transmitance of heat；Glass recovers bright again when illumination weakens, and improves light and its carries the transmitance of heat.It is this
Can with sooner or later and the four seasons environmental change, and change the intelligent glass of light transmittance and shading coefficient automatically, with Low emissivity energy-conservation
Advantage not available for glass, has caused the special attention of people.
At present, have and the photochromic hardboard of multilayer is clamped between two blocks of sheet glass, a kind of obtained photochromic interlayer
Glass；Also have and argent and halogen simple substance are added separately in other frits, it is obtained a kind of with photochromic effect
The lens blank answered；Or a kind of body glass of colour-changed due to gradual light-changing is produced using heat treating process or reduction treatment legal system
Glass；Even some have been mounted directly the discoloration glass such as traditional silver halide on the vehicle body of car, automobile, commercial vehicle and car respectively
Glass.In addition, the patent of external also some photochromic glasses, but be the improved technology to silver halide and photosensitizer system mostly, and
And electrochromic substance is all in glass body.But, the discoloration of above-mentioned photo chromic glass is relatively low.
On State Intellectual Property Office of the People's Republic of China website, patent related to the present invention 1 is found, specifically
Information is as follows：
Denomination of invention：Photochromic glass
Application number：CN201220426400.5
Inventor：Dong Qingshi；Zhang Qi；Wan Junpeng
Summary：The utility model is applied to glass technology field, and there is provided a kind of photochromic glass.The photochromic glass
Glass includes upper glassy layer, lower ply of glass and photochromic film layers, and the photochromic film layers are located at the upper glassy layer
Between lower ply of glass.The utility model photochromic glass, by setting light-induced variable between upper glassy layer and lower ply of glass
Coloring agent lamella, makes the photochromic glass have significant color changeable effect.
Above-mentioned patent employs a kind of new photochromic film, and effectively visible ray and purple have been obstructed when intensity of illumination is strong
Outer light and its heat of carrying are got in, and can be due to that the membership of entering for preventing visible ray influences indoor lighting, and in temperature
The suitable spring and fall of degree does not need the noon of trap heat, because light is blocked, it is impossible to which Time for Sunshine is sufficient, temperature is suitable
The indoor environment of people.
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 photochromic dimming glass.
To realize above-mentioned utility model purpose, the technical solution of the utility model is：A kind of photochromic dimming glass, bag
The first glass basis 1 is included, the lower surface of the first glass basis 1 is sequentially provided with photochromic film layers 2, the glass of liquid crystal film 3 and second
Glass matrix 4, between the first glass basis 1 and photochromic film layers 2, between photochromic film layers 2 and liquid crystal film 3 and
Bonded and connected by PVB films between the glass basis 4 of liquid crystal film 3 and second, loophole is additionally provided with photochromic film layers 2
5。
Further, a diameter of 0.5-5mm of loophole 5, the distance at the adjacent edge of loophole 5 is 0.5-5mm.
Further, the upper and lower surface of liquid crystal film 3 is covered with conductive layer, and conductive layer passes through chaff and peripheral control unit
Electrical connection.
The beneficial effects of the utility model are：
The utility model is possible to automatically controlled dimming liquid crystal film with that can combine with photochromic photochromic film
Use, and loophole is provided with photochromic film, when light is weak, whole glass is colourless transparent glass, is normally adopted
Light；When intensity of illumination is strong, because the effect of photochromic film can stop visible ray and ultraviolet and its heat of carrying
Get in, but because loophole enters without influenceing indoor lighting by some light；When light is too strong, it is necessary to further resistance
Enter fashionable every light and heat, can be switched with startup power supply, start the dimming function of liquid crystal film, glass is changed into light tight shape
State, is at this moment also used as the glass curtain for showing and uses, and can arbitrarily switch according to the need for people.
