But single silver low radiation coated glass of strange land processing

Technical field

But the utility model relates to single silver low radiation coated glass of a kind of strange land processing, belongs to glass structure and material technology field.

Background technology

Common in the market single silver low radiation plated film product, along with the lifting of home equipment performance and come into operation in enormous quantities, market is further nibbled and is compressed, therefore large glass deep processing enterprise is in order to keep the competitive edge with small processing factory, just must utilize the advantage of self overseas equipment performance, enhance productivity, but the single silver low radiation coated glass that strange land processing therefore occurred, manufacturer utilizes its production efficiency efficiently, reduce product cost to promote competitive power, but yet single silver low radiation coated glass of the processing of strange land in the market, often because film hardness is not enough, resistance of oxidation is relatively poor, causes scuffing in preprocessing process easily, scratch, and the storage time is grown slightly and just oxidative phenomena can occur, has had a strong impact on the quality of product.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of film hardness is big, resistance of oxidation strong and be difficult for scratching, scratch, but and single silver low radiation coated glass of long strange land processing that can oxidation of storage time.

The utility model is achieved through the following technical solutions:

But single silver low radiation coated glass of a kind of strange land processing; it is characterized in that; it comprises seven layers of structural sheet that forms by plated film from bottom to top altogether, is followed successively by base plate glass, first dielectric layer, first protective layer, silver layer, second protective layer, the 3rd protective layer and second dielectric layer.

Wherein, the material of described first dielectric layer and second dielectric layer is Si3N4; The material of first protective layer and second protective layer is NiCr; The material of the 3rd protective layer is CrNx.

The beneficial effects of the utility model are: the utility model is by the film layer structure of himself, make that it can be when transporting for long-distance, processing pre-treatment (cutting, wash mill) or pyroprocessing (tempering, hot bending), its outward appearance and performance all can not be affected, wear-resisting and antioxidant property is better, but standing storage is used, and can guarantee that its hot merit performance is better than common single silver low radiation coated glass.

Embodiment

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail:

Fig. 1 is the structural representation of the utility model one embodiment.

But single silver low radiation coated glass of strange land processing; it comprises seven layers of structural sheet that forms by plated film from bottom to top altogether, is followed successively by base plate glass 1, first dielectric layer 2, first protective layer 3, silver layer 4, second protective layer 5, the 3rd protective layer 6 and second dielectric layer 7.Wherein, the material of first dielectric layer 2 and second dielectric layer 7 is Si3N4; The material of first protective layer 3 and second protective layer 5 is NiCr; The material of the 3rd protective layer 6 is CrNx.

As shown in Figure 2: at first base plate glass 1 is cleaned, clean up after drying, pass through the preliminary vacuum transition again, be coated with first dielectric layer 2, first protective layer 3, silver layer 4, second protective layer 5, the 3rd protective layer 6 and second dielectric layer 7 successively.

Wherein, first dielectric layer 2 and second dielectric layer 7 exchange sial target sputter in nitrogen, argon atmosphere of negative electrode by rotation, Si:Al=92:8 wherein, and effect is a, provides adsorptive power between silver layer and dielectric substrate; B, protect whole film layer structure, reduce oxidation, improve physics and chemical property; The optical property and the color of c, controlling diaphragm system;

Silver layer 4 is by silver-colored target sputter in argon atmosphere of direct current planar negative electrode, and its effect as the major function layer is: reduce radiant ratio,, heat preservation effect heat insulation to play;

First protective layer 3 and second protective layer 5 be then by the sputter in the straight argon atmosphere of direct current planar negative electrode NiCr alloys target, Ni:Cr=80:20 wherein, and effect is: a, protection silver layer are not oxidized; B, increase the bonding force of silver layer with other rete;

In addition, the 3rd protective layer 6 is by the sputter in nitrogen, argon atmosphere of direct current planar negative electrode Cr target, and effect is: a, strengthen the protection to silver layer; B, increase the bonding force of silver layer with other rete;

The utility model adopts German Feng. the magnetron sputtering coater that the Ardennes is received, the processing parameter that employing table 1 is listed, use 7 to exchange the rotation double cathode, 4 direct current planar negative electrodes, but the single silver coating glass of the low radiation of making the processing of modified form described in the utility model strange land, the list of locations of its processing parameter and target is as follows:

Illustrate:
