Description
Technical field
The present invention relates to a kind of ornamental glass, particularly a kind of arbitrarily intelligent glass of light modulation.
Background technology
Glass is the inside and outside ornament materials commonly used of building, we can say ubiquitous from the glass curtain wall to the window.Glass curtain wall has not only beautified architectural appearance, also has certain heat-blocking action.But, glass curtain wall exists that outward appearance is single, heat radiation is big, to neighboring buildings and the bigger shortcoming of environmental impact, especially the spacing between the residential building in China city is generally all less, comes into plain view each other behind the installation glass curtain wall, and the privacy of shelter weakens greatly.When using window-glass, people generally adopt the way that curtain, window shutter are installed to realize purpose heat insulation, attractive in appearance, that maintain secrecy.But curtain is installed not only increases investment, and takies the interior space, and curtain also must often clean and change, and in addition, the switch curtain also brings many inconvenience sometimes.Therefore, people give very big expectation to the function of glass, wish to have a kind of can according to people's wish change glass transmittance, have the glass of curtain effect.
People's above-mentioned hope has been satisfied in the appearance of intelligent dimming glass.Intelligent dimming glass is a kind of electrochromism dimming glass, and it utilizes safe low-voltage to control the state of functional material in polyester film or the interlayer, and then reaches the purpose of variable color light modulation.The shade of electrochromism dimming glass can be controlled by changing electric current, and then regulates sun lights and go into indoor intensity.When applying voltage for the electrochromism dimming glass, electrochromic material wherein is painted, and when removing voltage, intelligent dimming glass can not fade, and has only when applying rightabout voltage for the electrochromism dimming glass, and intelligent dimming glass just can fade.That is to say, only just need impressed voltage with the process of fading, thereby have energy-saving effect painted.When intelligent dimming glass was opaque, it was exactly a kind of concealed curtain, had a lot of incomparable advantages: at first, use intelligent dimming glass just the entity curtain needn't be installed again, promptly saved the space, also avoided flying upward, improved indoor sanitary condition because of the dust that mobile curtain causes; Secondly, intelligent dimming glass has antiultraviolet and sound insulation function, is a kind of environmentally friendly machine; The 3rd, intelligent dimming glass can be regulated the transmitance of sun power, thereby has saved heating or the energy that freezes of buildings; The 4th, but intelligent dimming glass whole implementation not only also can be set the light modulation zone arbitrarily by user's requirement to a certain local dimming; At a lot of special occasions, be installed in and play prompting or Presentation Function on fixed building and the driving vehicle.These functions will be given its extremely wide application prospect.
The intelligent dimming glass of Chu Shouing all is to realize the purpose of light modulation by adding liquid crystal material layer in the market, and for example Chinese utility model patent instructions CN2725290Y discloses a kind of intelligent dimming glass that liquid crystal material layer is installed.But liquid crystal material is not a kind of desirable electric light regulates material.At first, the transparency of liquid crystal material is relatively poor, and when the electric light adjusting made liquid crystal be in " pass " state, it is very dark that indoor meeting becomes, and the spectral modulation amplitude is less; Secondly, when liquid crystal material is regulated the material use as electric light, generally need higher voltage to drive; In addition, the uvioresistant irradiation ability and the stability of liquid crystal material are not good, thereby are not suitable for Application in Building.For example publication number is that the Chinese invention patent of CN101188886 discloses a kind of all solid state electric driven color-changing part again, its structure be on tin-doped indium oxide (ITO) glass substrate, deposit successively tungsten oxide film as negative electrode photochromic layer, lithium metaborate and lithium sulfate mixture film as ion conductor layer, nickel oxide film as anode photochromic layer and tin-doped indium oxide film as transparency electrode, this variable color element has the performance that changes light transmission.But this variable color element does not have the infrared external reflection effect, thereby can influence the heat-proof quality of light modulation intelligent glass; In addition, ito glass as intelligent dimming glass to electrode, the electrochemistry capacitance of its unit area is less usually, generally need apply the electrochemistry capacitance that voltage improves the ITO conductive film by raising, and then improves the electrochromism efficient of intelligent dimming glass.But raising applies the cycle life that voltage can shorten the electrochromism intelligent dimming glass.
