Abstract
The utility model provides a sun light control film capable of permeating visual reverse infrared ray. The utility model adopts a structure consisting of a multilayer film made of a polyester base, metal and metal oxide, and an external protective layer, and is characterized in high permeability concerning the visual light and high reflectance concerning the near infrared ray and reverse infrared ray. The utility model can be applicable to various occasions needing transparency and heat insulation such as vehicle windows, building windows and transparent doors of display deep freezers with an energy saving function.
Description
The utility model relates to optical field, is a kind ofly to have high permeability in the visible region, and has the sunlight control function film of high reflectance near infrared and mid and far infrared zone.
Energy-conservation and environmental protection is an important topic of human social.How rationally utilizing sunshine is one of them important sub-problem.In some occasion, as have a window of the buildings of central air conditioner system, only need to allow the visible light in the sunshine partly see through, to guarantee room lighting, and completely cut off to fall the infrared light part that can produce thermal effect in the sunshine, the most significant near infrared part of thermal effect (wavelength coverage is at 0.8～2.5 micron) in sunshine especially.In the market heat reflection film or visible range transmitance are not enough, or the isolated property of region of ultra-red is bad, and particularly the isolated property of near-infrared region is bad, are difficult to satisfy the requirement that makes full use of sunshine.
The purpose of this utility model is to provide a kind of visible region transmitance height, and the isolated property near infrared and mid and far infrared zone is good, and sunlight control function film with low cost.
The purpose of this utility model realizes by vacuum deposition multiple layer metal on the polyester base material and metal-oxide film structure.By the thickness of accurate each layer of control metal and metal-oxide film, can realize the selective permeation or the reflection of spectrum, thereby can reach visible, anti-infrared purpose.
Description of drawings of the present utility model is as follows:
Fig. 1 is the cross-sectional view of sunlight control function film of the present utility model.
Fig. 2 is the optical transmission spectra curve map of sunlight control function film of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.But do not limit content of the present utility model.
Accompanying drawing 1 is the cross-sectional view of sunlight control function film of the present utility model.Substrate 1 is flexible mylar material, plates the multilayer optical film structures 9 of metal and metal oxide thereon with the method for vacuum sputtering deposition film.This multilayer optical film structures can make it under the situation that keeps the visible region high permeability, and infrared light is had high reflectance.A concrete example is that this multilayer optical film structures 9 is made of the chromium 7 of silver 6,0.4 nanometer thickness of tin indium oxide 5,11 nanometer thickness of chromium 4,78 nanometer thickness of silver 3,0.4 nanometer thickness of tin indium oxide (ITO) 2,11 nanometer thickness of 35 nanometer thickness and the tin indium oxide 8 of 35 nanometer thickness.Adopting tin indium oxide as the high refractive index medium material, is because its sputter rate is very high, can the high speed film forming, help enhancing productivity.In film system, adopted the double layer of metal silverskin, can improve the reflectivity of near infrared region (0.8～2.5 micron) effectively, thereby improve effect of heat insulation greatly.Then in order to the protection silverskin, their very thin thickness works to spectrum metallic chromium layer hardly, but can delay the oxidation of silverskin effectively.The optical transmission spectra of this film system is seen accompanying drawing 2, as can be seen it in the transmitance of visible region greater than 80%, for the mean transmissivity of near-infrared region then less than 2%.
This mylar 1 that is coated with multilayer optical film structures 9 is combined with each other with another mylar 11 usefulness compound adhesive 10, can plays nonvolatil protective effect this multilayer optical film structures.So just constituted sunlight control function film of the present utility model.In compound adhesive, ultraviolet absorption material can also be mixed, the ultraviolet isolation capacity of this function film can be improved.On the outside surface of mylar 11, can also carry out stiffened and hydrophobic and handle, can play the effect of anti-contamination and anti-scratch.
This function film is attached on the article such as door glass etc. of window glass, automotive glazing and display refrigerator-freezer of buildings, can plays and both kept high transparent, can completely cut off the effect of sun heat radiation again effectively, have power saving function.
The utlity model has following advantage:
1. have visual field high permeability (greater than 80%), infrared region high reflectance (greater than
90%) characteristics have considerable energy saving, insulation effect.
2. have production efficiency height, advantage that cost is low, be fit to large-scale production and popularization.
3. owing to being flexible membraneous material, applicable to various complex-curved article.
Claims (3)
1. a sunlight is controlled film; form by multi-layer film structure and external protection that polyester substrate, metal and metal oxide are formed; it is characterized in that adopting the multilayer optical film structure of mylar/oxide/metal silver/crome metal/oxide/metal silver/crome metal/oxide/mylar; make it have high permeability, and have high reflectance at region of ultra-red in the visible region.
2. sunlight control film as claimed in claim 1 is characterized in that containing in its multilayer optical film structure two-layer or two-layer above metal silverskin.
3. sunlight control film as claimed in claim 1 is characterized in that containing in its multilayer optical film structure as thin as a wafer Titanium or metallic chromium layer.
