Abstract
The invention discloses temperable low-emissivity coated glass, which comprises a glass substrate and a coating plated onto the glass substrate. The temperable low-emissivity coated glass is characterized in that from the glass substrate outward, the coating comprises a first dielectric layer, a first protective layer, an infrared-blocking layer, a second protective layer and a second dielectric layer. In temperable low-emissivity coated glass disclosed by the invention, through additionally arranging the metal protective layer outside the infrared-blocking layer, the abrasion resistance and the oxidation resistance are improved, so that the coated glass is capable of bearing long-distance transport, pretreatment and high-temperature, but the product appearance and the performance cannot be influenced.
Description
Technical field
The present invention relates to a kind of coated glass, specifically is a kind of radiation coated glass capable of being toughened.
Background technology
Along with the lifting of home equipment performance and coming into operation in enormous quantities of coated glass product, common low radiation coated glass product market competition in the market is fierce.The tradition low radiation coated glass must be accomplished double glazing at short notice after glass is accomplished plated film, so the glass synthetic hollow in strange land of can not transporting for long-distance, and this has brought restriction for glass large-scale promotion and processing.Some glass deep processing enterprise utilizes the advantage of self overseas equipment performance in order to keep from advantage in competition, enhances productivity; Reduce cost promoting competitiveness of product, but and the low radiation coated glass of strange land processing just comes therefrom, yet but the low radiation coated glass of the processing of strange land in the market is often not enough owing to film hardness; In preprocessing process, cause scuffing, scratch easily; And oxidation resistance is relatively poor, and the storage time is grown slightly and just oxidative phenomena can occur
Summary of the invention
Technological order of the present invention is to solve the problem that exists in the prior art, and the radiation coated glass capable of being toughened that a kind of wearability is high, antioxygenic property is good is provided
Technical scheme of the present invention is a kind of radiation coated glass capable of being toughened, comprises glass substrate and is plated in the plated film on the glass substrate, it is characterized in that:
Said plated film outwards comprises first dielectric layer, first protective layer, infrared ray barrier layer, second protective layer and second dielectric layer successively from glass substrate.
Said infrared ray barrier layer is a silver alloy.As preferably, said silver alloy can be selected existing Ag-Cu alloy, Ag-Zn alloy, Ag-Ni alloy or Ag-Ti alloy for use.
The film material of described first dielectric layer, second dielectric layer is Si
3N
4, SiOxNy, SiO
2In one or more, promptly its film material can be the individual layer that a kind of material constitutes, or the rete that mixes of different materials, or the combination layer of different materials individual layer stack separately constitutes.
The film material that said first protective layer, second protective layer are is one or more among NiCr, NiCrOx, CrNx, ZrO, AZO, the NiCrNx.
The process for plating of above-mentioned each rete is:
First dielectric layer and second dielectric layer are through rotating the sial target sputter in nitrogen argon atmosphere that exchanges negative electrode, wherein mass ratio Si: Al=92: 8; The rete effect of first dielectric layer is a, stops the Na+ in the glass in rete, to permeate; B, the absorption affinity of rete is provided; C, protect whole film layer structure, reduce oxidation, improve product physics and chemical property; The optical property and the color of d, controlling diaphragm system; The rete effect of second dielectric layer is: a, improve the mechanical performance of glass, b, protect whole rete, chemical substance in the blocks air or oxygen corrode the infrared barrier layer, c, adjustment glass colour.
The infrared ray barrier layer is through alloy silver target sputter in argon atmosphere of direct current planar negative electrode; This rete is the major function layer, is used to reduce radiance,, heat preservation effect heat insulation to play;
First protective layer and second protective layer, through the sputter in straight argon or argon oxygen, argon nitrogen atmosphere of direct current planar negative electrode, target can be one or more in NiCr, Cr, AZO, the Zr target, wherein mass percent Ni: Cr=80: 20; The effect of this rete is: a, the protection silver layer not oxidized; B, increase the adhesion of silver layer with other rete.
Radiation coated glass capable of being toughened of the present invention, compared to existing low radiation coated glass, its wearability and antioxygenic property all are greatly improved, and have effectively avoided the problem that exists in the existing product.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic flow sheet that is coated with of the present invention.
The specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, the present invention is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
As shown in the figure; A kind of radiation coated glass capable of being toughened; Comprise glass substrate and be plated in the plated film on the glass substrate, said coating outwards comprises first dielectric layer, first protective layer, infrared ray barrier layer, second protective layer and second dielectric layer successively from glass substrate.
The rete of described first dielectric layer, second dielectric layer is Si

2In one or more.
Said infrared ray barrier layer is a silver alloy, said silver alloy a kind of in preferred Ag-Cu alloy, Ag-Zn alloy, Ag-Ni alloy or the Ag-Ti alloy in current material.
Said first protective layer, second protective layer are one or more formations in NiCr, NiCrOx, CrNx, ZrO, AZO, the NiCrNx material.
The present invention adopts magnetron sputtering coater, adopts following table to list technological parameter, uses 4 to exchange the Rotating Double negative electrode; 3 direct current planar negative electrodes are made radiation coated glass capable of being toughened of the present invention, and wherein 1#, 2# are coated with first dielectric layer; 3# is coated with first protective layer; 4# is coated with the infrared ray barrier layer, and 5# is coated with second protective layer, and 6#, 7# are coated with second dielectric layer.The list of locations of its technological parameter and target is following:
To pass through cleaning-drying before the glass substrate coating, carry out the forevacuum transition then, after product is coated with completion, carry out following processing technology:
A, cutting, no specific (special) requirements will in time be washed mill after the cutting;
B, wash mill (critical process), the suggestion belt sanding, if last machine mill, the pinch roller and whenever increase a shower then should lowerd, developing machine hairbrush at a distance from a segment distance adopt quality softer and the water heating after, begin to clean, clean the use deionized water;
C, tempering (or hot bending) adopt the convection type annealing furnace, on the common white glass basis plinth of same thickness, suitably reduce the tempering temperature, prolong heat time heating time;
D, hollow are used deionized water, and the membrane removal of limit portion.
