It is geometric thickness；Wherein, the refractive index value of film layer is the refractive index value at 550nm wavelength, and the optical thickness of film layer is
The product of the geometric thickness of refractive index and film layer at 550nm wavelength.
As shown in figure 1, the low radiation coated glass containing three layers of infrared reflecting layer of the present invention, including glass substrate
100, it is characterised in that：Outwards set gradually on 100 surface of the glass substrate,
First medium layer 1, its geometric thickness are 30～50nm；
First infrared reflecting layer 2, its geometric thickness are 7～16nm；

Outermost dielectric layer 7, its geometric thickness be 150～200nm, optical thickness be 300～360nm, refractive index be 1.7～
2.6, the material of the outermost dielectric layer 7 is selected from Zn, Sn, Ti, Nb, Zr, Hf, Mg, Ni, In, Al, Ga, W, Bi metal-oxide
And its at least one in mixture, or be selected from Si, Al, Zr, Ti, Y, Hf, Nb, Ta metal nitride or nitrogen oxides and its
At least one in mixture.
Wherein, outermost dielectric layer 7 is used to protect its other film layer between glass substrate 100, each by appropriate design
The thickness of film layer is particularly the geometric thickness and optical thickness of outermost dielectric layer 7, it is possible to increase the heat stability of membrane system, chemistry are steady
Qualitative and mechanical stability, so as to realize high-durability, and can make final laminated glass articles have neutral color
Reflection appearance.Preferably, the outermost dielectric layer 7 includes Si3N4Sublayer, AlN sublayers, ZnSnOx sublayers, ZnO sublayers, TiO2Son
Layer, SnO2Sublayer, WO3Sublayer, Bi2O3Sublayer, HfO2Sublayer and Nb2O5At least one of sublayer, namely the outermost medium
Layer 7 can be Si3N4Sublayer, AlN sublayers, ZnSnOx sublayers, ZnO sublayers, TiO2Sublayer, SnO2Sublayer, WO3Sublayer, Bi2O3Son
Layer, HfO2Sublayer or Nb2O5Sublayer, it is also possible to which the sublayer more than any two-layer or two-layer in by above-mentioned sublayer is constituted.
Meanwhile, here with outermost dielectric layer 7 as ZnO:It is durable that Al/ZnSnOx citings illustrate height of the present invention
Property the laminated glass articles that constitute of low radiation coated glass there is the reflection appearance of neutral color, wherein ZnO:Al is represented and is doped with
The ZnO sublayers of Al, ZnO:The thickness of Al is 8nm, increases to 400nm from traditional 20nm by changing the thickness of ZnSnOx,
The normal incidence reflection colour and 60 ° of incidence reflection colors of final laminated glass articles are measured respectively, so as to assess ZnSnOx films
Impact of the change of thickness degree to the low angle and high angle reflection colour of its laminated glass articles.In Fig. 2 and Fig. 3, a+ represents red
Color, a- represent green, and b+ represents yellow, and b- represents blueness；It is in coordinate system, more more shallow to the close expression color of coordinate origin,
Otherwise then represent that color is deeper.
As can be seen that when the thickness of ZnSnOx is 40nm (in traditional Three-silver-layer low-radiation coated glass from Fig. 2 and Fig. 3
The typical thickness of ZnSnOx) when, the reflection colour of the low angle of its laminated glass articles and 60 degree is green and lavender respectively；
When being even up to hundreds of nanometers with the increase of the thickness of ZnSnOx, in most thickness ranges, its laminated glass articles
Reflection colour inaesthetic color is presented, for example as can be seen from Figure 2 the thickness of ZnSnOx be 80nm when its interlayer glass
The normal incidence reflection colour of glass product is dark green, and during 120nm, the normal incidence reflection colour of its laminated glass articles is in yellow,
During 180nm, the normal incidence reflection colour of its laminated glass articles is dark green；Or high angle observation and low angle when observing are in
Existing significant color distortion, such as the normal incidence reflection colour of its laminated glass articles when the thickness of ZnSnOx is 180nm in Fig. 2
It is dark green, and 60 ° of incidence reflection colors of its laminated glass articles are presented aobvious when in Fig. 3, the thickness of ZnSnOx is 180nm
What is write is light blue.Based on this, due to the front as the transparent glass window on the vehicles, particularly automobile, skylight, rear shelves or
Side window often requires that the colored appearance for having neutrality or certain pleasant when observing in low angle and high angle, such as bluish-green
Color, light blue or bluish violet, the thickness of traditional ZnSnOx have practical value, but simply increase the thickness of ZnSnOx then very
It is difficult to obtain the laminated glass articles with practical value.Conversely, in the present invention, the thickness by each film layer of appropriate design is special
The geometric thickness and optical thickness of outermost dielectric layer 7, such as the thickness of the ZnSnOx illustrated in Fig. 2 and Fig. 3 be 155nm, 160
When its laminated glass articles normal incidence reflection colour in pale blue green, 60 ° of incidence reflection colors are in muted color；Now, when
When the thickness of ZnSnOx is 155nm or 160nm, the geometric thickness of corresponding outermost dielectric layer 7 is 163nm or 168nm, optics thickness
Spend for 334nm or 344nm.It is visible with reference to Fig. 2 and Fig. 3, ZnSnOx thickness be 155nm or 160nm near, exist one it is thick
Degree scope, can make its laminated glass articles reflection colour when low angle and high angle are observed basically identical and have to make us pleased
The thickness in two dotted ellipse regions in happy appearance color, i.e. Fig. 2 and Fig. 3, the geometric thickness of preferred outermost dielectric layer 7 is
150～175nm, optical thickness is 310～340nm, and the thickness of outermost dielectric layer 7 is arranged on what the membrane system in the range of this built
Laminated glass product has great practical value.It must be noted that the thickness of outermost dielectric layer 7 is arranged except with reference to conventional three silver medals
Outside the technical scheme that mentality of designing and the present invention are provided, even if carrying out to the thickness of other dielectric layer film layers and infrared reflecting layer
Global optimization is arranged, and can not obtain the qualified laminated glass articles of spectral technique index and color characteristics.
Preferably, in order to further optimize film performance, outermost dielectric layer 7 can be worked as comprising Si3N4It is during sublayer, described
Si3N4Doped with Al, Ni, Zr or Hf in sublayer.Equally, when outermost dielectric layer 7 includes ZnO sublayers, mix in the ZnO sublayers
It is miscellaneous to have Al, Ga, Mo, Mg, In, F or B；When outermost dielectric layer 7 include ZnSnOx sublayers when, in the ZnSnOx sublayers doped with
Al, Sb, Mg, Ni or Y.
Wherein, first infrared reflecting layer 2, the second infrared reflecting layer 4 or 6 major function of the 3rd infrared reflecting layer are to use
In reflection infrared ray, reduce infrared ray and transmit from low radiation coated glass, so first infrared reflecting layer 2, second is red
The film material of outer reflective layer 4 or the 3rd infrared reflecting layer 6 can select any material for being capable of reflecting infrared energy, for example
At least one of (but being not limited to) in silver, gold, copper, aluminum and its alloy, is preferably the conjunction of silver or argentiferous in the present invention
