Description
Technical field
The present invention relates to energy-conserving and environment-protective Material Field, 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, and the nonrenewable resources utilization ratio based on coal is low, and renewable resource development and utilization level is low, environmental situation is serious, high-grade energy is under-supply, and form growing tension, thus energy saving standard becomes themes of the times.In all kinds of energy consumption, 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 in ascendant trend year by year, energy waste is extremely serious.
In modern building, the most serious energy consumption is from the glass as exterior wall or window, and the area ratio that glass accounts for exterior wall is increasing, and the heat exchange loss undertaken by ordinary glazed window according to measuring and calculating accounts for 58% and 73% respectively at winter and summer.This is in the scope of 0.2 ~ 2.5 μm because solar energy about 99% is distributed in wavelength, wherein the ultraviolet region of 0.2 ~ 0.38 μm accounts for about 8% of gross energy, the visible ray of 0.38 ~ 0.78 μm accounts for about 43%, and the near infrared region of 0.78 ~ 2.5 μm accounts for about 48%.And simple glass does not have ability of regulation and control to the sunshine of different wave length, summer can not effectively end near-infrared sunshine, adds the cooling load of air-conditioning, and in winter, indoor heat is scattered and disappeared by glass surface with thermal-radiating form again, adds the insulation load of air-conditioning.When adopting air-conditioning to regulate indoor temperature, according to measurement, cryogenic temperature improves 2 DEG C, and cooling load reduces about 20%; Heat temperature and turn down 2 DEG C, heating load reduces about 30%.Drop into low-E (Low-E) coated glass of the passive tune pattern of fever of business application at present, effectively can reduce the radiance of glass surface, and then reduce corresponding heat loss through radiation, but, this Low-E coated glass is once after structure is formed, its optical property does not just carry out reversible bidirectional modulation to obtain effect cool in summer and warm in winter with environmental change, and this is difficult to adapt to China major part and makes a clear distinction between the four seasons the demand in area.
In order to overcome the shortcoming of Low-E coated glass, sunlight controlling and low diathermaneity are combined, propose intelligent power saving glass, its optical property can carry out reversible bidirectional modulation with environmental change, mainly comprises the types such as gas-discoloration (air-sensitive), electrochromism (electricity is quick), thermochromism (temperature-sensitive).By the excitation of external condition, such energy-saving glass can realize the adjustment to sunshine light transmission, plays energy-conservation effect.In the implementation of above three kinds of energy-saving glass, gas-discoloration and electrochomeric glass are while adjustment sunshine, and have negative influence to the transmitance of visible ray, affect the visual clarity of energy-saving glass, thus range of application is restricted.
Thermochromism glass mainly concentrates on the reversible transition characteristic utilizing vanadium dioxide, i.e. semiconductor-metal transition (SMT) characteristic that has of vanadium dioxide.Raise with temperature, reach phase transition temperature (T
c) after, the crystalline phase of vanadium dioxide occurs by the transformation of monoclinic phase to Tetragonal, correspondingly its optical property changes, infrared light changes lower permeability into by higher permeability, but the permeability of visible region is substantially constant, can not cause obvious visible change, before and after phase transformation simultaneously, ultraviolet is almost all absorbed.And hypovanadic oxide-based thermochromism glass and other intelligent power saving glassy phase ratios, structure is simple, and cost is low, and phase transition temperature can be regulated by suitable technique and composition control, has a extensive future.
But although the vanadium dioxide film of individual layer can regulate and control infrared light transmittance, its visible light transmissivity is low, the infrared regulating force difference of infrared light transmittance (between semiconductor phase and the Metal Phase) is weak, intelligent power saving weak effect.Therefore, under the prerequisite guaranteeing vanadium dioxide thermochromic properties, improving the transmitance of visible ray, strengthening the infrared ability of regulation and control of sunshine is improve the key of vanadium dioxide intelligent power saving performance.
