Description
Technical field
The present invention relates to a kind of anti-high-efficiency and energy-saving single silver LOW-E coated glasss high thoroughly high.
Background technology
Building energy consumption majority is lost in by door and window, and new Low emissivity LOW-E glass, it has visible ray higher
Transmitance, it is ensured that natural lighting is good, and the transmission of sun heat radiation can be effectively controlled again, can nearly, far-infrared thermal spoke
Penetrate and reflect back, used under any climatic environment, can reach control sunlight, energy saving, heat and control to adjust.As long as dress
Upper low emissivity glass, interior spends little air-conditioning expense just can forever to maintain condition cool in summer and warm in winter, i.e. summer anti-heat energy to enter the room,
Winter anti-heat energy leakage, with splendid bi-directional energy-saving effect, and can be irradiated with shielding of ultraviolet, make furniture color constant
Color.There is outstanding energy-saving effect just because of low radiation coated glass, Low emissivity LOW-E glass possesses replacement cement wall brick
One of main building materials as heavy construction, are that thick wall brick is sloughed in heavy construction, change and the transparent glass of energy-conservation of putting on " outward
Clothing ", for building designers provide new green choice.As China accelerates urbanization paces, house in all parts of the country and business
Industry building emerges in large numbers on a large scale, and energy-saving glass has quietly turned into the new lover in construction market.
China is energy consumption big country, and energy resource consumption the first in the world, the discharge the second in the world of greenhouse gases, wherein building energy consumption is accounted for
30% or so of total energy consumption, and the energy consumption of wherein glass part is 50% or so of building energy consumption.China is by constitutional law in recent years
Laws ＆ Regulations system requirement and some manufacturers popularization, either the production capacity or actual production of coated glass do not stop expansion
Greatly, close to 1 Yi ㎡, increasing energy-saving glass is entered in common furniture construction, as the utilities building of top-grade building,
Its outer glaze also switchs to energy-conservation more preferably high-performance Low-E glass by common low emissivity glass, and its usage amount does not stop increase,
High-performance Low-E glass is also more and more applied architectural.
The list silver low-E glass that the current country is commonly used cannot fully meet the demand in market, and high performance
Double silver-colored Low-E glass are also simply just to start to step into market in recent years, double silver-colored Low-E as energy-saving glass high-end product,
Because production technical difficulty is higher, there is angle colorations deviation weight, plate the aspect such as film uniformity and strange land tempering
Technical barrier, the yield rate and production efficiency of double silver-colored Low-E is all relatively low, and production cost remains high always, to a certain extent
Limit the application of high-performance Low-E glass.In view of this, in the market occurs in that modified list silver Low-E glass, and the type is produced
The energy-efficient performance of the product single silver Low-E glass general higher than in the market, less than general double silver Low-E glass.The glass of the type
The production of glass can avoid the problem that double silver Low-E glass are encountered, in energy-efficient performance also close to double silver-colored Low-E glass, compared with
Low production cost and production efficiency higher are as the new focus of energy-saving glass in the market, but common modified Dan Yin
Low-E glass is simple due to membrane system result, to reach energy-efficient performance higher, sacrifices the visible light transmissivity of product, relatively low
Visible light transmissivity reduce the daylighting effect of glass, only have the application market of small range in sun-drenched southern area,
The application of modified list silver Low-E is limited to a certain extent, but because modified Low-E glass takes into account low cost and Gao Jie
The advantage of energy performance, still has preferable development potentiality in modified list silver Low-E glass products field.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided a kind of anti-high-efficiency and energy-saving single silver LOW-E coated glasss high thoroughly high.
Anti- high-efficiency and energy-saving single silver LOW-E coated glasss high thoroughly high, are that the first electricity is outwards being disposed with from substrate glass
Dielectric layer, the second dielectric layer, Ag layers, protective layer, the 3rd dielectric layer, the 4th dielectric layer, wherein the first dielectric layer is
SiAlNx, the second dielectric layer is ZnAlOx, and protective layer is Ti, and the 3rd dielectric layer is ZnAlOx, and the 4th dielectric layer is
SiAlNx。
Compared with prior art, the present invention can reach following technique effect：
1st, the energy-saving effect of double silver Low-E is reached using the production technology of single silver Low-E, with more stable, simpler life
Production. art and lower cost produce the premium quality product of suitable middle and high-end market.
2nd, bluish grey colored appearance, order has used the building of the membrane system product more attractive in appearance.
3rd, Wear Resistance can be outstanding, can carry out strange land tempering processing, and excellent performance can effectively improve the finished product of product
Rate, reduces production cost.
Brief description of the drawings
Fig. 1 traditional single silver film system.
Fig. 2 single silver film systems of the invention.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The Film Design conventional scheme of existing offline low radiation coated glass is shown in Fig. 1：For dielectric layer SiAlNx due to
Film adhesion with functional layer Ag is poor, it is necessary to adds one layer of transition zone NiCr alloy film in dielectric layer and functional layer, is film
Layer improves adhesive force, and structure needs to use 2 layers of NiCr films in this, and the decay to light is larger, in addition the work function of NiCr alloys（About
5.0eV）Work function more than Ag（4.26eV）, the electronics in the Ag will migrate into NiCr layers, causes the conductive capability of Ag to decline,
Infrared albedo is declined, energy-efficient performance reduction is shown as, is unfavorable for producing high performance low radiation coated glass product.
As shown in Fig. 2 the present invention for Ag characteristic, on dielectric layer SiAlNx increase by one time ZnAlOx layer, nAlOx with
Ag has good film adhesion, cancels barrier layer 1 so that ZnAlOx layers and Ag layers of directly contact.In addition by the material of barrier layer 2
Material is replaced by lower Ti layers of work function（4.33eV）, and ZnAlOx layers is plated outside Ti, due to the work function of ZnAlOx（About
4.1）Less than Ti and Ag, the electronics in the ZnAlOx of dielectric layer 2 will be toward migration in Ag layers, and the electronics of ZnAlOx will in dielectric layer 3
Migrated toward Ti, the overall electric conductivity for improving functional layer Ag rises to infrared reflection, shows as the raising of energy-efficient performance.
When tempering heat treatment is carried out, metal Ti layers of complete oxidation can be reduced film layer to the other film layer structure by ZnAlOx
Optical attenuation so that membrane system product has light transmittance higher, is especially suitable for producing high-transparency super energy-conservation low radiation coated glass.
It is below a kind of embodiment therein：
SiAlNx：45-60nm
ZnAlOx：25-35nm
Ti：5-15nm
Ag：12-17nm
ZnAlOx：15-20nm
SiAlNx：10-25nm
The double glazing manufactured using present invention design membrane system（6Low-E+12A+6C）Optics and power save parameters it is as follows：
