Detailed description of the invention

Fig. 1 is structural schematic diagram provided by the utility model.

In figure, glass-base 1, first medium layer 2, functional layer 3, protective layer 4, second dielectric layer 5, the first SiNx layer 21, First ZnAlOx layer 22, AZO layer 6, the 2nd ZnAlOx layer 51, the second SiNx layer 52.

Specific embodiment

As shown in Figure 1, this high-permeability, tempered single silver-layer low-radiation glass, including glass-base 1, glass-base 1 is from the inside to the outside It is successively arranged first medium layer 2, functional layer 3, protective layer 4 and second dielectric layer 5, first medium layer 2 includes being arranged from the inside to the outside The first SiNx layer 21 and the first ZnAlOx layer 22, functional layer 3 is Ag layer, and protective layer 4 is NiCr layers, and second dielectric layer 5 includes AZO layer 6, the 2nd ZnAlOx layer 51 and the second SiNx layer 52 being arranged from the inside to the outside.

More specifically, the first SiNx layer 21 with a thickness of 5~14nm.When glass is processed in annealing furnace, temperature highest Up to 700 DEG C or so, the sodium element in process in glass itself is heated in order to prevent, aggravates diffusive migration into film layer, Destroy the functional layer structure containing Ag.This layer should not be too thick, and excessive SiNx can reduce film layer transmitance.

Further, the first ZnOx layer 22 with a thickness of 20~30nm.Adhesion layer or seed layer as Ag layers, With a thickness of 20~30nm, the flatness of entire film layer can be improved, convenient for the deposition of Ag in functional layer.

Further, functional layer 3 with a thickness of 3~9nm.Its major function is the spoke that glass product is reduced using Ag Rate is penetrated, sunlight is filtered into cold light source, improves through performance.

Further, protective layer 4 with a thickness of 1nm.Its major function is protected using the fine and close oxidation resistant characteristic of film layer Shield silver is not oxidized.This layer should not be too thick, and excessive NiCr can reduce film layer transmitance.

Further, AZO layer 6 with a thickness of 5~10nm.As the transition zone of NiCr and ZnAlOx, due to AZO layers of knot Structure densification is smooth, improves the binding force of NiCr layers with ZnAlOx layers.Especially during High temperature tempered, whole film layer is improved Stability.

Further, the 2nd ZnOx layer 51 with a thickness of 12~23nm.Film surface surface resistance can be reduced, it is saturating to increase visible light Cross rate.

Further, the second SiNx layer 52 with a thickness of 10~16nm.It is mainly used for enhancing coated glass surface machinery Performance, it is unsuitable blocked up, influence transmitance.

The high-permeability, tempered list silver-layer low-radiation glass visible light transmittance T of this programme is 82~86%, outdoor face visible light Reflectivity is lower than 6%.

High-permeability, tempered single silver-layer low-radiation glass of this programme, the positive face color of glass surface: a*g be -5~-1, b*g be -10~- 2；60 degree of Side Colors of glass surface: -5~-1, b*g is -10~-2.

It can be more convenient for the heat such as subsequent tempering, hot dipping, hot bending using high-permeability, tempered single silver-layer low-radiation glass of this programme Treatment process.Glassware has good appearance performance, damage resistant abrasion and the excellent properties such as corrosion-resistant after heat treatment process.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.

Although glass-base 1, first medium layer 2, functional layer 3, protective layer 4, second dielectric layer is used more herein 5, the terms such as the first SiNx layer 21, the first ZnAlOx layer 22, AZO layer 6, the 2nd ZnAlOx layer 51, second SiNx layer 52, but not It rules out the possibility of using other terms.The use of these items is only for be more convenient to describe and explain the utility model Essence, it is contrary to the spirit of the present invention to interpret them as any one of the additional limitations.
