Description
Technical field
The present invention relates to a kind of high saturating high anti-high-efficiency and energy-saving single silver LOW-E coated glass.
Background technology
Building energy consumption majority is run off by door and window, and novel Low emissivity LOW-E glass, it has higher visible light transmissivity, guarantee natural lighting is good, can effectively control again sun heat radiation through, can nearly, far-infrared heat radiation reflects back, and uses under any climatic environment, all can reach and control sunlight, economize energy, heat control and regulation.As long as load onto low emissivity glass, indoor spend little air-conditioning expense just can forever maintain condition cool in summer and warm in winter, and namely summer, anti-heat energy was entered the room, winter, anti-heat energy was revealed, there is splendid bi-directional energy-saving effect, and can irradiate by shielding of ultraviolet, make the nondiscolouring of furniture color.Just because of low radiation coated glass, there is outstanding energy-saving effect, Low emissivity LOW-E glass has possessed one of alternative cement wall brick main building materials becoming heavy construction, for thick wall brick is sloughed in heavy construction, change and energy-conservation transparent glass " coat " of putting on, for building designers provide new green choice.Along with China accelerates urbanization paces, house in all parts of the country and commercial building emerge in large numbers on a large scale, and energy-saving glass has quietly become the new lover in construction market.
China is energy consumption big country, energy resource consumption the first in the world, and the discharge the second in the world of greenhouse gases, wherein building energy consumption accounts for about 30% of total energy consumption, and wherein the energy consumption of glass part is about 50% of building energy consumption.China requires and the popularization of some manufacturers through state's laws rules and regulations in recent years, that the production capacity of coated glass or actual production do not stop to expand, close to 1 Yi ㎡, increasing energy-saving glass enters in common furniture construction, as the utilities building of top-grade building, its outer glaze also transfers energy-conservation better high-performance Low-E glass to by common low emissivity glass, and its use amount does not stop to increase, and high-performance Low-E glass is also more and more applied in architectural.
The silver-colored low-E glass of the list that Present Domestic generally uses cannot meet the demand in market completely, and high performance two silver-colored Low-E glass is also just in recent years just start progressively to come into the market, two silver-colored Low-E is as the high-end product of energy-saving glass, because production technical difficulty is higher, there is the technical barrier of the aspects such as angle colorations deviation weight, plated film uniformity and strange land tempering, yield rate and the production efficiency of two silver-colored Low-E are all on the low side, production cost remains high always, limits the application of high-performance Low-E glass to a certain extent.In view of this, market there is modified list silver Low-E glass, the energy-efficient performance of the type product higher than the silver-colored Low-E glass of list general on market, lower than general two silver-colored Low-E glass.The production of the glass of the type can avoid the difficult problem that two silver-colored Low-E glass is encountered, at energy-efficient performance also close to two silver-colored Low-E glass, lower production cost and higher production efficiency become focus new on energy-saving glass market, but common modified list silver Low-E glass due to film tying fruit simple, for reaching higher energy-efficient performance, sacrifice the visible light transmissivity of product, lower visible light transmissivity reduces the daylighting effect of glass, application market among a small circle is only had in sun-drenched southern area, limit the application of modified list silver Low-E to a certain extent, but because the advantage of low cost and high energy-efficient performance taken into account by modified Low-E glass, good development potentiality is still had in modified list silver Low-E glass product field.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of high saturating high anti-high-efficiency and energy-saving single silver LOW-E coated glass.
High saturating high anti-high-efficiency and energy-saving single silver LOW-E coated glass; outwards be disposed with the first dielectric layer, the second dielectric layer, Ag layer, protective layer, the 3rd dielectric layer, the 4th dielectric layer from substrate glass; wherein the first dielectric layer is SiAlNx; second dielectric layer is ZnAlOx; protective layer is Ti; 3rd dielectric layer is ZnAlOx, and the 4th dielectric layer is SiAlNx.
Compared with prior art, the present invention can reach following technique effect:
1, adopt the production technology of single silver-colored Low-E to reach the energy-saving effect of two silver-colored Low-E, produce the premium quality product of applicable middle and high-end market with more stable, simpler production technology and lower cost.
2, pewter outward appearance, the building that order employs this film system product is more attractive in appearance.
3, Wear Resistance can be outstanding, can carry out strange land tempering processing, excellent performance, effectively can improve the yield rate of product, reduces production cost.
Accompanying drawing explanation
Single silverskin system that Fig. 1 is traditional.
Fig. 2 single silverskin system of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The Film Design conventional scheme of existing off-line low radiation coated glass is shown in Fig. 1: for the SiAlNx of dielectric layer due to poor with the film adhesion of functional layer Ag, one deck transition zone NiCr alloy film must be added at dielectric layer and functional layer, for rete improves adhesive force, in this, structure needs to use 2 layers of NiCr film, larger to the decay of light, the work function (about 5.0eV) of NiCr alloy is greater than the work function (4.26eV) of Ag in addition, electronics in this Ag will move to NiCr layer, the conductive capability of Ag is caused to decline, infrared albedo is declined, show as energy-efficient performance to reduce, be unfavorable for producing high performance low radiation coated glass product.
As shown in Figure 2, the present invention is directed to the characteristic of Ag, dielectric layer SiAlNx increases a ZnAlOx layer, nAlOx and Ag has good film adhesion, cancels barrier layer 1, ZnAlOx layer is directly contacted with Ag layer.Barrier layer 2 material is replaced by the lower Ti layer (4.33eV) of work function in addition, and outside Ti, plate ZnAlOx layer, because the work function (about 4.1) of ZnAlOx is lower than Ti and Ag, electronics in the ZnAlOx of dielectric layer 2 will move in Ag layer, in dielectric layer 3, the electronics of ZnAlOx will move in Ti, the overall electric conductivity improving functional layer Ag, rises to infrared reflection, shows as the raising of energy-efficient performance.This film layer structure is when carrying out tempering and being heat treated in addition, and ZnAlOx by metal Ti layer complete oxidation, can decrease the optical attenuation of rete, and what make film system product has higher light transmittance, is applicable to very much producing the super energy-conservation low radiation coated glass of high-transparency.
Be below a kind of embodiment wherein:
SiAlNx：45-60nm
ZnAlOx：25-35nm
Ti：5-15nm
Ag：12-17nm
ZnAlOx：15-20nm
SiAlNx：10-25nm
Use the present invention the to design optics of double glazing (6Low-E+12A+6C) that film system manufactures and power save parameters as follows:
