Description
Technical field
The utility model relate to a kind of can superelevation thoroughly single silver-colored Low-E coated glass of strange land tempering.
Background technology
In the Film Design of Conventional Off-line low radiation coated glass, general using NiCr alloy as the protective layer of functional layer silver layer and optical attenuation layer, this alloy material has certain attenuation to visible ray, cannot the saturating low radiation coated glass of production superelevation (be called for short Low-E), the monolithic visible light transmittance rate of the low radiation coated glass using this alloy material to produce generally is no more than 80%, and the saturating Low-E of superelevation that light transmittance is greater than 80% has just been at a complete loss as to what to do, and after some product light transmittance reaches 80% reluctantly, the scratch resistance capability of product is poor, film adhesion is insecure, product cannot heat-treat processing (being commonly called as tempering process), be unfavorable for following process.
Summary of the invention
Be difficult to production superelevation saturating Low-E product to solve in prior art and improve the film adhesion of the saturating product of superelevation, strengthen the scratch resistance capability of rete, the utility model provides one and has comparatively high visible light transmissivity, film layer structure is stablized, scratch resistance capability is strong, and strange land can be carried out can the Film Design of tempering processing.
A kind of can strange land tempering superelevation thoroughly single silver-colored Low-E coated glass be outwards be disposed with first medium layer, second dielectric layer, Ag layer, barrier layer, the 3rd dielectric layer, the 4th dielectric layer from substrate glass, wherein first medium layer is ZnSnOx, second dielectric layer is ZnAlOx, barrier layer is Ti, 3rd dielectric layer is ZnAlOx, and the 4th dielectric layer is TiOx.
Compared with prior art, the utility model can reach following technique effect:
1, good energy-saving effect is kept while having higher visible light transmissivity.
2, product is stablized, and scratch resistance capability is strong, and processability is excellent.
3, can heat-treat processing (tempering process), based on this characteristic, this product can adopt the production technology of tempering after first plated film, enhances productivity, and increases yield rate.
Accompanying drawing explanation
Single silverskin system that Fig. 1 is traditional.
Fig. 2 single silverskin system of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The Film Design conventional scheme of existing off-line low radiation coated glass is shown in Fig. 1: this film system is owing to adopting two-layer NiCr alloy as barrier layer protected Ag layer; there is higher attenuating on two-layer barrier layer to visible ray, makes this film system cannot produce thoroughly high and the saturating product of superelevation (visible light transmittance rate >=80%).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 utility model adopts ZnSnOx and ZnAlOx as basic unit in the film system of existing off-line low emissivity glass plated film, contributes to the energy-efficient performance improving product.Metal Ti replaces original alloy material NiCr, and after Ti layer, add plating ZnAlOx material, uses the TiO with stronger mechanical performance at film system outermost layer protective layer
2material.
The utility model, for the characteristic of Ag, cancels barrier layer 1, forms good contact, have good film adhesion, ZnAlOx layer is directly contacted with Ag layer using ZnSnOx with ZnAlOx material as basic unit 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; ZnAlOx can by metal Ti layer complete oxidation; decrease the optical attenuation of rete; what make film system product has higher visible light transmissivity; adopt the protective layer of TiOx rete the most with better mechanical performance, high index of refraction; can improve on the one hand the scratch resistance capability of product, refractive index higher on the other hand can the anti-reflective effect of product further, the visible light transmissivity of increase product.
Be below a kind of embodiment wherein:
TiOx：40-50nm
ZnAlOx：13-17nm
Ti：1-2nm
Ag：8-12nm
ZnAlOx：13-17nm
SiAlNx：22-28nm
Optics and the power save parameters of the double glazing (6Low-E+12A+6C) using the utility model design film system to manufacture are as follows:
