Description
Technical field
The present invention relates to the energy-conserving and environment-protective field of materials, relate more specifically to a kind of inorganic material laminated film and application thereof of environmental protection and energy saving.
Background technology
China is an energy starved country, is that master's nonrenewable resources utilization ratio is low with coal, and renewable resource development and use degree is low; Environmental situation is serious; High-grade energy is under-supply, and the form growing tension, thereby energy-conservation and environmental protection have become themes of the times.In all kinds of energy consumptions; The building energy consumption of China has accounted for more than 1/3rd of social total energy consumption; Wherein the energy consumption of heating and air-conditioning accounts for about 55% of building total energy consumption; And China's construction unit area energy consumption is 2 to 3 times of developed country, and is ascendant trend year by year, and energy waste is extremely serious.
In modern times in the building, the most serious energy consumption is from the glass as exterior wall or window, and glass to account for the area ratio of exterior wall increasing, the heat exchange loss of carrying out through the simple glass window according to measuring and calculating accounts for 58% and 73% respectively at winter and summer.This is because solar energy about 99% is distributed in the scope that wavelength is 0.2～2.5 μ m; Wherein the ultraviolet region of 0.2～0.38 μ m accounts for about 8% of gross energy; 0.38 the visible light of～0.78 μ m accounts for the near infrared region of about 43%, 0.78～2.5 μ m and accounts for about 48%.And simple glass does not have ability of regulation and control to the sunshine of different wave length; Can not effectively end the near-infrared sunshine summer, increased the cooling load of air-conditioning, and in winter; Indoor heat scatters and disappears through glass surface with thermal-radiating form again, has increased the insulation load of air-conditioning.Adopting air-conditioning to regulate under the situation of indoor temperature, according to measuring, cryogenic temperature improves 2 ℃, and cooling load reduces about 20%; Heat temperature and turn down 2 ℃, heat load and reduce about 30%.Dropped at present low-E (Low-E) coated glass of the passive accent pattern of fever of commercial application; Can effectively reduce the radiance of glass surface; And then reduce corresponding heat loss through radiation, still, this Low-E coated glass is in case after structure forms; Its optical property is not just carried out reversible bidirectional modulation obtaining effect cool in summer and warm in winter with environmental change, and this is difficult to adapt to the make a clear distinction between the four seasons demand in area of China's major part.
In order to overcome the shortcoming of Low-E coated glass; Combine with low diathermaneity sunlight is controlled; Intelligent power saving glass has been proposed; Its optical property can be carried out reversible bidirectional modulation with environmental change, mainly comprises gas-discoloration (air-sensitive), electrochromism (electricity is quick), thermochromism types such as (temperature-sensitives).Through the excitation of external condition, such energy-saving glass can be realized the adjusting to the sunshine light transmission, plays energy-conservation effect.In the implementation of above three kinds of energy-saving glass, gas-discoloration and electrochomeric glass have negative influence to the transmitance of visible light when regulating sunshine, influence the visually-clear property of energy-saving glass, thereby range of application is restricted.
Thermochromism glass mainly concentrates on the reversible transition characteristic of utilizing vanadium dioxide, and promptly the semiconductor that has of vanadium dioxide-metal changes (SMT) characteristic.Raise with temperature, reach phase transition temperature (T
c) after; The crystalline phase of vanadium dioxide takes place by the monocline transformation of cubic phase in opposite directions; Correspondingly its optical property changes, and infrared light is by changing lower permeability into than higher permeability, but the permeability of visible region is constant basically; Can not cause tangible visible change, ultraviolet ray almost all is absorbed before and after the phase transformation simultaneously.And, hypovanadic oxide-based thermochromism glass and other intelligent power saving glassy phase ratios, simple in structure, cost is low, and phase transition temperature can be regulated with forming to control through suitable technology, has a extensive future.
Yet though the vanadium dioxide film of individual layer can be regulated and control the infrared light transmitance, its visible light transmissivity is low, a little less than the infrared regulating force (semiconductor and metal mutually between the difference of infrared light transmitance), and the intelligent power saving weak effect.Therefore, under the prerequisite of guaranteeing the vanadium dioxide thermochromic properties, the infrared ability of regulation and control of the transmitance of raising visible light, enhancing sunshine is to improve the key of vanadium dioxide intelligent power saving performance.
