Abstract
The utility model discloses a low radiation film-coated glass of special film system, including a glass uropatagium. The utility model is characterized as follows: the glass uropatagium is compounded with five films; wherein, the first film, that is to say the substrate, is a metal oxide film layer; the second film is a metal or alloy barrier layer; the third film is metal silver; the fourth film is a metal or alloy barrier layer; the fifth film, that is to say the surface layer, is a metal oxide film layer. The utility model can protect the silver layer from being influenced by oxygen and avoid oxidation of the silver layer, making one layer of function films of the low radiation film-coated glass, the silver layer, have a good effect, obtaining stable low radiation function.
Description
[technical field]
The utility model relates to a kind of coated glass, especially a kind of low radiation coated glass.
[background technology]
Low emissivity glass is that a kind of high visible sees through and the coated glass of high IR line reflection.Because of its to natural light and the almost unobstructed effect of sun power, make decorating has the mansion of this functional glass or the effect that dwelling house can receive sun power, in the winter of cold, this part energy is that people generally accept and need.And in the winter of cold, indoorly need heating, and the thermal radiation wavelength of heating installation is generally the above long wave of 5 μ m known to the people, and low radiation coated glass can stop seeing through of long-wave infrared, that is to say the heat that can retain indoor, make the warming and heat insulation expense reduce.
With reference to figure 1, above-mentioned low radiation coated glass generally adopts the four layer series structure, promptly is coated with successively on glass substrate 1:
First rete is a metal oxide layer 2, and material adopts SnO, ZnO or TiO
2Deng, be used for adjusting the color of coated glass;
Second rete is a silver layer 3, and the radiant ratio of silver can accomplish to be about 0.02;
The tertiary membrane layer is a silver layer protective membrane 4, is generally metal level, and it mainly acts on is the protection silver layer, makes silver layer not oxidized;
The 4th rete is a metal oxide layer 5, and material adopts SnO or TiO
2Deng, it mainly acts on is that whole film system is shielded, and exempts to be scratched.
Above-mentioned this low radiation coated glass in actual use; because first rete and the 4th rete are metal oxide layer; structure own is more open; and in order to obtain light transmission preferably; its thickness can not be too thick; so this metal oxide layer is not enough to the protection of silver layer, the silver layer oxidative phenomena takes place through regular meeting, make coated glass lose low radiation functions.
[utility model content]
The purpose of this utility model is to provide a kind of low radiation coated glass that can prevent that the oxidized a kind of special film of silver layer from being.
The low radiation coated glass that a kind of special film of the utility model design is includes glass substrate, it is characterized in that be compounded with five retes on glass substrate, wherein: first rete is that bottom is the metal oxide rete; Second rete is the metal or alloy blocking layer; The tertiary membrane layer is a silver layer; The 4th rete is the metal or alloy blocking layer; The 5th rete is that upper layer is the metal oxide rete.
Characteristics of the present utility model are: with double layer of metal or alloy barrier layer is that second rete and the 4th rete are in the middle of silver layer is wrapped in the tertiary membrane layer, as the sandwich Layer cake, because metal or alloy compact structure, stable performance, can guarantee that silver layer is not influenced by oxygen, avoid silver layer oxidized, make that one of the functional film layer of low radiation coated glass is that silver layer can play effect well, obtain stable low radiation functions.
The first above-mentioned rete can be selected SnO, ZnO, TiO
2Or the like, be used for adjusting the color of coated glass.
The second above-mentioned rete, the 4th rete can be selected metal Ti or alloy NiCr respectively.
The main effect of the 5th rete is that whole film system is protected, and prevents physical abuse, and material can be selected SnO or TiO
2Deng.
[description of drawings]
Fig. 1 is the structural representation of existing low radiation coated glass;
Fig. 2 is a structural representation of the present utility model.
[embodiment]
With reference to figure 2, the low radiation coated glass that a kind of special film of the utility model design is is to be compounded with five retes on glass substrate 10, and wherein: first rete 11 is that bottom is SnO; Second rete 12 is a metal Ti, plays barrier effect; Tertiary membrane layer 13 is an argent; The 4th rete 14 is a metal Ti, plays barrier effect; The 5th rete 15 is that upper layer is SnO, and main effect is that whole film system is protected, and prevents physical abuse.
Above-mentioned second rete 12 and the 4th rete 14 are in the middle of silver layer is wrapped in, as the sandwich Layer cake with tertiary membrane layer 13.Because the metal Ti compact structure, stable performance can guarantee that silver layer is not oxidized.
As first rete, its material can adopt other metal oxide, as ZnO, TiO
2Deng; As second rete, its material can adopt alloy NiCr; As the 4th rete, its material can adopt alloy NiCr; As the 5th rete, its material can adopt other metal oxide, as TiO
2Deng.
