Description

But a kind of off-line tempering intelligence low radiation coated glass
Technical field
This patent relates to building energy conservation coated glass field, but specifically refers to the off-line tempering intelligence low radiation coated glass that a kind of suitable industrialization is produced.
Technical background
Along with advocating of energy-saving and emission-reduction and low-carbon (LC) life, the building energy-saving environmental protection is all more and more paid attention in countries in the world.According to statistics, the Chinese architecture energy consumption accounts for about 27% of social total energy consumption, and along with the expansion of scale of urbanization, this ratio is also increasing year by year.Studies show that window is the principal passage of buildings and outside energy exchange, the energy consumption of glass port accounts for 40%～50% of whole building energy consumptions.In winter, window (individual layer) has accounted for whole buildings and 45% of outside energy exchange with extraneous energy exchange, and summer, and the energy exchange by window and extraneous realization is then up to 71%.Therefore, the energy exchange of reduction window is the key that reduces whole building energy consumption.In Europe, 80% double glazing uses low radiation (Low-ε) coated glass; The dwelling house of the U.S. 75% and 1/3rd public building adopt Low-ε coated glass.The throughput of the American-European Low-ε of developed country coated glass accounts for 90% of world's total amount.The present Low-ε of China energy-saving glass fraction of coverage less than 2%, therefore, the novel energy-conserving glassy product of cultivating China's independent intellectual property right is extremely urgent.
Because ultrared heat effect is the most direct, it also is the most responsive one section electromagnetic radiation can feeling heat of human body.In order to realize the function of low radiation energy-saving, normally at one or more layers nano level infrared-reflecting layers (being called functional layer) of surface of ordinary glass coating.Glass surface coating one deck or which floor to have the glass of low radiation functions film at, be called low emissivity glass (Low Emissivity Glass is called for short Low-ε glass).At present functional layer material is mainly the only Ag film about 10nm and improve the supplementary layer of functional layer thermostability, anti-reflection, adjusting glassy product appearance color of thickness.The effect of low radiation functions film is exactly the infrared energy part that reflects away in the sunlight, and keeps visible light to have higher transmittance, makes the sun become " cold light source " as far as possible.In winter, room temp is than outdoor height, and indoor object radiation infrared rays is difficult for escaping by the energy-saving glass door and window, reaches warming effect; In summer, external temperature is than indoor height, and the infrared rays of outside is difficult for entering into indoor, makes indoor comparatively nice and coolly, significantly reduces the energy consumption of freezing in winter heating and summer.
Yet, this only with the coated glass of Ag film as functional layer, no matter when all be to be in low radiation regimes, all the time the infrared energy in the sunlight is partly had high-reflectivity.This is very favourable when needing low radiation functions usually, but also has certain drawback simultaneously, under the situation that does not need low radiation functions, still it is then greatly unfavorable to shield energy, for example when room temp lower and when needing outdoor solar irradiation to enter, but because the height of Ag film reflects and can't enter, can not regulate making room temp reach the pleasant trim point of body sense automatically.
And the VO with semi-conductor-metal phase change characteristic 2Film then can be realized intelligent regulating effect according to temperature variation, just in time can remedy the deficiency of Ag film functional layer.The single silverskin of the nanometer system and the VO with intelligent regulating effect that will have low radiation energy-saving effect 2The nano thin-film coupling combines together the two.Make it when having low radiation effect, also have intelligent regulating effect.
Since nineteen fifty-nine Morin finds VO 2Semi-conductor-metal phase change phenomenon since, people are to VO 2Semi-conductor-metal phase change and the optics of following with phase transformation and the sudden change of electrical properties produced keen interest.When temperature is higher than 68 ℃, metallographic phase VO 2The light transmission rate of (R) reflection ray, particularly infrared band sharply reduces, thereby can effectively stop ultrared entering, and avoids temperature to continue to rise.And when temperature drops to below 68 ℃, change semi-conductor phase VO into 2(M) improve seeing through infrared light.Like this, VO 2Film just can be circularly the outer solar radiant energy stream of surge chamber and indoor overheating or cold excessively automatically, realize the intelligent control to room temp.And the best use temperature in the actual application is near the room temperature 30 ℃, in the hope of obtaining higher regulating power and eliminating its phase transformation heat stagnation.Want VO 2Transformation temperature be adjusted near the best room temperature, need realize that doped element comprises W, Mo, Al, Ti, Nb and Ta by the doping of long radius metallic element, single blending is two mixes two kinds of patterns for having of adopting usually.Nearest result of study shows, VO 2Transformation temperature can be adjusted near the room temperature, can be up to 47% to the switch regulating effect of infrared light.
Other disclosed VO 2The relevant patent of base intelligent power saving coated glass is as the patent " hypovanadic oxide-based composite film that a kind of radiant ratio is adjustable and preparation method thereof " of patent publication No. CN101817644A, though also mention VO 2Nano thin-film is combined with conductive metal film, is keeping effective performance that reduces radiant ratio under the vanadium dioxide thermochromism prerequisite to reach, but because its designed film structure can not carry out the processing of off-line tempering, can't realize large-scale industrialization production and application.
Therefore, form the product of energy industrialization and large-scale production and application, product film system can be prepared fast by the most frequently used magnetically controlled sputter method of industrialization, the more important thing is, but institute plated film system will possess the characteristic of off-line tempering, could really realize scale operation flexibly like this and reduces cost.
But off-line tempering coated glass has the characteristic of many excellences, has solved the difficult problem that common coated glass can't realize that large-scale industrialized production is used.The toughened glass resistance to impact shock of condition of equivalent thickness is 3～5 times of simple glass; Bending strength is 3～5 times of simple glass; The resistance to thermal shocks matter of toughened glass has 3～5 times raising than simple glass, generally can bear the above difference variation of 250 degree, has burst positive effect to preventing heat; Its supporting capacity is big, even fragmentation also is cellular broken little obtuse angle particle, the injury of human body greatly reduced, and be a kind of shatter proof glass.And, but off-line tempering performance has avoided online tempering to handle the shortcoming that can't satisfy the arbitrary shape product demand, has reduced the requirement to coating film production line equipment, has greatly discharged production capacity, thereby has reached the needs that satisfy handiness scale operation and consumption.
Summary of the invention
This patent is by the low radiation functions film system that will have energy-conserving action and the vanadium dioxide film system coupling with intelligent regulating effect; but again in conjunction with the silicon nitride protective coating of off-line tempering; make coated glass when having low radiation energy-saving effect, but also have with temperature intelligent regulating effect and off-line tempering performance.By between each functional film layer, adding modified layer or anti-reflection layer; but carry out overall film and be optimization design and the skin tempering protection structure design of antireflection structure; make its performance reach best, but form the off-line tempering NEW TYPE OF COMPOSITE film system that has intelligence and energy-conservation double effects concurrently.This NEW TYPE OF COMPOSITE film system can be after the unification of large-area glass substrate be coated with, cut into various different shapeies and size according to different customer demands again, carry out the off-line tempering at last and handle the formation product, thereby greatly strengthen the handiness of producing design, can discharge production capacity, be very beneficial for scale operation and reduce cost.
By reference to the accompanying drawings 3 and accompanying drawing 4, can see that low radiation functions film system and vanadium dioxide ir radiation intelligence regulates the characteristic that composite function film system that film system constitutes possesses excellent low radiation energy-saving effect simultaneously and regulates with temperature intelligent.Individual layer VO 2The transmission spectrum of nano thin-film is higher than transformation temperature T in temperature as shown in Figure 3 cAfter, the light transmission rate of infrared band sharply reduces, thereby can effectively stop ultrared entering, and avoids temperature to continue to rise.By to VO 2Nano thin-film doping long radius metallic element, doped element comprises W, Mo, Al, Ti, Nb and Ta, the wherein a kind of element that both can mix, and multiple element simultaneously also can mix, preferably, adopt and singly to mix or two pattern of mixing is adjusted near the room temperature transformation temperature of vanadium dioxide.Form compound film system in conjunction with the single silver-colored film of the nanometer with low radiation functions again, its transmitted spectrum as shown in Figure 4, when temperature is lower than transformation temperature, compound film system has certain transmitance at infrared band, thereby can make the interior room temp that improves of infrared rays part transmission inlet chamber in the outdoor sunlight; And when temperature was higher than transformation temperature, compound film system sharply reduced in the transmissivity of infrared band, the infrared energy that reflection room enters outward, thus avoid room temp to continue to rise.So just make combined films system both have low radiation functions, have temperature variant intelligent regulating effect again, reach excellent energy-saving effect.
By being to add ZnO, SiO between each functional layer at composite function film 2, Si 3N 4, Al 2O 3, SnO 2, TiO 2Modified layer and the antireflection layer of film system as a whole.On the one hand the main component of glass is oxide compound, and has close lattice parameter between these deielectric-coating, is conducive to combination each other, as the transition layer between glass substrate and functional layer, can reinforcing membrane system and glass substrate between sticking power; Be different from the non-crystalline state of glass on the one hand, these dielectric films are polycrystalline structures, are conducive to improve crystallinity, electroconductibility and the optical property of functional film layer as the buffering modified layer; On the other hand as sealing coat, for the protection of silver layer, prevent that silver layer is oxidized and prevent that functional layer from being corroded by obnoxious flavour, influences the performance of function film in tempering or hot bending process in external environment.Can also regulate the thickness of optimizing medium layer and increase compound film system in the transmitance of visible light wave range by choosing the medium layer material of suitable specific refractory power simultaneously.
In order to reduce the reflected light on coated glass surface, need carry out the design of antireflective film system to it usually.The calculating of reflectivity can be adopted the eigenmatrix method, for the individual layer antireflective film:
B C = cos δ 1 i n 1 sin δ 1 in 1 sin δ 1 cos δ 1 1 n 2
For centre wavelength, have

Obtaining specular reflectance included is
R = ( n 0 - Y n 0 + Y ) 2 = ( n 0 - n 1 2 / n 2 n 0 + n 1 2 / n 2 ) 2
As seen, when
