3deng the outermost layer as low radiation film, can improve low radiation film and using ACF or the PSA characteristic that is electrically connected to as bus.Although above-mentioned materials is known, as Chinese patent CN201654382U discloses a kind of structure of heating glass bonded by anisotropic conductive rubber, relate at liquid crystal (LCD) and show the ITO of being coated with film on glass, adopt ACF nation to determine the method for Technical form LCD heating glass.At glass surface, being coated with ITO film is a proven technique, normally under certain vacuum tightness and temperature (200 ~ 350 ℃) environment, use the technology such as evaporation (Evaporative) or sputter (Sputtering) to form the approximately ITO film of 100 ~ 800nm, electrically conducting transparent of one deck at glass surface.The ACF nation mentioning in this patent determines the thermocompressor platform of Technology Need special use to provide suitable temperature and pressure to make itself and ITO film form good electrical connection.
But the transparent conductive oxide rete described in the present invention is as ITO, AZO, ATO, IZO, GZO, IGZO, IMO and LaNiO
3deng the aspect such as role, making method and applied environment in can electrically heated low-emission coated laminated glass, be different from transparent conductive oxide rete of the prior art, below take ITO and describe as example.
First, in Chinese patent CN201654382U, the Main Function of ITO is used as heating unit; And in the present invention, what play heating unit effect is the silver layer in low radiation film, the Main Function of ITO is as the layer that conducts between bus and silver layer.In traditional low radiation film, the thickness of each layer is generally several nanometers to tens nanometer, and at outermost layer, is generally SiNx, TiOx, ZrO
2, ZnSnOx or SiO
2deng medium layer, to Ag layer is protected when high-temperature heat treatment.But the contact interface of the medium layers such as the material such as PSA and ACF and SiNx or TiOx, take SiNx as example, the potential barrier effect producing because of the electrical insulating property that SiNx material is good, make the conducting particles containing in the materials such as PSA and ACF that good being electrically connected to cannot occur with the silver layer in low radiation film, therefore can not realization cmpletely lead to electrically heated function, be embodied in and cannot heat or exist focus.In the present invention, outermost layer ITO is because of its electroconductibility having, and the conducting particles that is conducive to contain in the materials such as PSA and ACF is crossed the medium layers such as SiNx, thereby produces good being electrically connected to silver layer.Therefore, the existence of outermost layer ITO is equivalent to reduce the potential barrier of the medium layer between ITO and silver layer.

In addition, in the present invention, the applied environment of ITO film is also different.Conventional ito thin film generally carries out anneal under vacuum environment, and annealing temperature is no more than 400 ℃.The anneal disclosing in U.S. Patent application US20090457006 is also to carry out under vacuum environment, and annealing temperature is no more than 450 ℃.But in the present invention,, because the distinctive abnormal curved surface shape of the vehicles or building window, glass port and the film system that is coated on glass port surface need to carry out the forming processes such as hot bending or tempering under high temperature (such as the temperature that is greater than glass softening point).The part forming as money base low-radiation film architecture, the high temperature that ITO rete stands reaches 600 ~ 700 ℃, and high temperature thermal treatment used as continuous bending furnace, annealing furnace etc. be not possess vacuum environment.After high-temperature heat treatment, the electrical properties of ITO rete is not damaged, and in the following embodiments, its resistivity is by 4.13 * 10 before thermal treatment
-3Ω m, drops to 1.21 * 10
-3Ω m, electroconductibility has obtained raising.
Further, described pressure sensitive adhesive or anisotropy conductiving glue contain metallic foil, wherein metallic foil can be used as the important carrier of current delivery, to reducing as much as possible current loss, play an important role, a lateral junction of described metallic foil and described pressure sensitive adhesive or anisotropy conductiving glue is combined, omit the operation of independent laminating metallic foil, simplified technical process.Meanwhile, described metallic foil surface arranges metal wire joint, and described metal wire joint is for being communicated with the direct line of power supply.For metal wire joint is fixed together with metallic foil better, preferably at described metallic foil outside surface, tin coating is set.
In order to improve the contradiction of visible light transmissivity and conductive film layer resistance in the visible light transmissivity of glass or balance low radiation film, in the glass baseplate surface of described low radiation film is not set, have at least a surface that anti-reflection film is set, described anti-reflection film is multilayer film.
Described intermediate polymer is generally selected thermoplastic material, and after being heating and curing, be transparence and have good sealing property, preferably polyethylene butyral (PVB) or ethylene-vinyl acetate copolymer, its thickness range is 10 microns to 10 millimeters.Described intermediate polymer is polyvinyl butyral (PVB) in an embodiment of the present invention, and thickness range is 0.5 millimeter to 2 millimeters.
The resistance per square scope of conventional low radiation film is 0.4 ~ 4 Ω/, and the resistance per square of preferred described low radiation film is 0.6 ~ 2.5 Ω/.The safety voltage of national regulation is 36V, and low radiation film of the present invention, under the power supply supply of this safety voltage, can provide 200～1000W/m
