Description
Technical field
Present invention relates particularly to a kind of clear glass heat-barrier material and its application.
Background technology
Glass is widely used in building, and there is provided daylighting and decorative effect with the transparent window material of vehicle.Common window material glass is handle
The separation layer that outdoor environment and the interior space are separated, although the circulation of air, steam, dust etc. can be obstructed, but to sun spoke
Ultraviolet, visible ray and the ultrared iris action penetrated are small.In the summer of sunlight strong, the infrared emanation of interior is irradiated to
It is the elevated importance of indoor temperature, is also the pith of cooling in summer air conditioning energy consumption.
Sunshine is reached after the absorption of atmosphere in the radiation components on ground, and ultraviolet accounts for 5%, it is seen that light accounts for 50%,
Infrared ray accounts for 45%.Wherein, the 95% of infrared energy concentrates on wavelength in the range of 760~2500nm, i.e. near-infrared model
In enclosing.Visible ray and infrared ray are all heat rays, and the object being sunlighted absorbs the visible ray and infrared light of solar radiation
Energy after be transformed into heat energy, raise the temperature of body surface.When summer solar radiation is most strong, construction wall hull-skin temperature
50~80 DEG C can be increased to.The heat energy of the outer surface savings of architectural exterior-protecting construction is conducted to interior by wall, makes room temperature liter
It is high.Strong solar radiation is directly by glass, and glass can reach 90% or so to the transmitance of visible ray and near infrared ray.By building
The windowpane of enclosed structure is built compared with the heat of wall, Energy Consumption of Walls accounts for the 20~30% of monolithic architecture total energy consumption, windowpane
Energy consumption account for 30~50%, it is more than the heat output of wall by the heat output of glass pane.The particularly building enclosure of modern architecture
Increasing using the area of windowpane, therefore, the energy consumption ratio of windowpane is also in increase, and exploitation energy-saving glass is building energy conservation
In the urgent need to.
In order to reduce the sun heat radiation got in from window-glass, polytype heat-protecting glass has been developed.As respectively
Kind of coloured glass, the energy-saving glass such as heat-reflecting glass, coated glass, pad pasting glass, coated glass.Although various coloured glass have
Certain effect of heat insulation, still, while infrared emanation is obstructed, most visible ray is also obstructed, glass is reduced
The visible light transmissivity of glass, influences indoor lighting；The action principle of heat-reflecting glass is reflecting sun heat radiation, due to glass
Mirror-reflection effect is strong, easily produces visible ray light pollution to environment and heat radiation is polluted, its application is by many limitations；Pad pasting
Glass, coated glass are to be prepared into heat-insulated film or insulating moulding coating by heat-barrier material and high polymer material are compound, be affixed on respectively or
It is coated on glass, forms heat-protecting glass.Adhering film to glass, glass coating film construction method are simple, cost is low, still, Heat insulation type adhering film
The problems such as ftractureing, come off, changing colour easily is produced by environmental aging with insulating moulding coating, the quality of product is influenceed.

The maximum infrared absorption wave band of outer heat-barrier material is in 760~1100nm, then with higher effect of heat insulation.
Common float glass has very strong absorption in the ultraviolet region that wavelength is less than 400 nm, in visible region and near-infrared
The transmitance in area is similar to straight line, stable in slightly above 90% level.Modern architecture power conservation requirement coating glass every
The sheet glass of float glass after hot coating, there is higher transmitance in the transmitance of visible region, near infrared band have compared with
Low transmitance.The heat-barrier material being currently used in glass heat-insulating coating is mainly ATO, ITO, but they wavelength 760~
1200 nm near infrared region transmitance is larger, just smaller in 1200~2500 nm infrared transmittivity.Yu Gang et al.（Yu Gang,

Phase, in November, 2009）Research has drawn the ultraviolet-visible and infrared transmittivity spectral characteristic of ito film：Ito film 400~
The transmitance of 1200nm wave bands is higher, and the infrared light transmittance that 1200~2500nm wave band is more than to wavelength is gradually reduced.Lee
Rather（Li Ning, Ph.D. Dissertation：Building glass insulating moulding coating is studied, Guangzhou, South China Science ＆ Engineering University, 2010）It has studied in water
Property polyurethane resin in, add 12.7% ATO heat-barrier materials prepare glass heat-insulating coating, on a glass be coated with 50 microns
Wet-film thickness, test obtains the spectral characteristic of heat insulating coating film after drying：Heat radiation of the ATO films to 760~1200nm infrared bands
Transmitance is all higher than 60%, and the rejection rate effect that 1200nm wave band is more than to wavelength is preferable.
Therefore, conventional clear glass infrared barrier material ITO and ATO infrared barrier wavelength are 1200~2500nm's
Wave band, its infrared transmittivity is reduced with the increase of infrared wavelength.That is ATO, ITO in infrared solar radiation intensity most
The barrier of infrared band near high 800nm is small, the effect of heat insulation of ATO, ITO heat-barrier material is have impact on, to improve
The rejection rate of infrared band near 800nm, it is necessary to increase the amount of ATO, ITO heat-barrier material.Therefore, one kind is developed in the sun
The maximum 800nm wave bands of infrared intensity have the material of high barriering rate, have important to the effect of heat insulation for lifting heat-protecting glass
