Abstract
The utility model discloses a low-radiation composite membrane, which comprises a silver layer and a metal protective layer, and is characterized in that: an oxide protective layer in an oxygen deficient state is plated on the outer part of the metal protective layer and is made of NiCrOx. In the low-radiation composite membrane, the oxide protective layer in the oxygen deficient state is plated on the outer part of the metal protective layer, namely a NiCr layer, so that a functional layer, namely an Ag layer can be protected well, and the visible light transmittance of the low-radiation composite membrane can be improved to a great extent; therefore, a product can acquire light transmittance to the greatest extent under the condition that low radiance is ensured; and the low-radiation composite membrane is extremely suitable for cold regions in the north.
Description
Technical field
The utility model relates to a kind of low radiation composite film, belongs to the film layer structure technical field.
Background technology
We know; traditional low radiation composite film; (one side or two sides) is the layer of metal protective layer in the silver layer outside; its material is NiCr; being coated with in the process of reality,, need to increase the thickness of coat of metal NiCr layer usually for defencive function layer Ag layer better; and make the transmittance of low radiation composite film reduce this moment.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of transmittance that can not influence composite membrane, and the effective low radiation composite film of defencive function layer Ag layer.
The utility model is achieved through the following technical solutions:
A kind of low radiation composite film comprises silver layer and coat of metal, it is characterized in that, also is coated with the protective oxide film that one deck is in oxygen debt state in the outside of coat of metal.
The material of described protective oxide film is NiCrOx.
The beneficial effects of the utility model are: the utility model is coated with the protective oxide film that one deck is in oxygen debt state again by the outside at coat of metal NiCr layer; defencive function layer Ag layer well not only; and can improve the visible light transmissivity of low radiation composite film significantly; product can guaranteed under the situation of low-E; obtain transmittance to greatest extent, be fit to very much north cold area and use.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the structural representation of another embodiment of the utility model.
Main Reference numeral implication is among the figure:
1, silver layer 2, coat of metal 3, protective oxide film.
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.
As shown in Figure 1: low radiation composite film; comprise silver layer 1 and coat of metal 2, wherein, be coated with coat of metal 2 in a side of silver layer 1; and also being coated with the protective oxide film 3 that one deck is in oxygen debt state in the outside of coat of metal 2, its material is NiCrOx.
Fig. 2 is the structural representation of another embodiment of the utility model.
Low radiation composite film comprises silver layer 1 and coat of metal 2, wherein, has been coated with coat of metal 2 in the both sides of silver layer 1, and also has been coated with the protective oxide film 3 that one deck is in oxygen debt state in the outside of coat of metal 2, and its material is NiCrOx.
The plating method of the above-mentioned protective oxide film that is in oxygen debt state 3 is: when application vacuum magnetic-control sputtering film coating method is coated with low radiation composite film, add a certain amount of O in the coat of metal NiCr layer therein
2, add O
2Concrete grammar be: in pure Ar atmosphere, add a small amount of O in the negative electrode of the plane N iCr of normal sputter
2, and the voltage condition of observing negative electrode, this voltage can be along with O
2Increase and raise, increase O gradually
2, till this cathode voltage no longer raises, if add O
2Overvoltage then can reduce gradually, at this moment need turn off O
2, treat that voltage is stable after, open once more and suitably reduce O
2, be elevated to a certain degree up to voltage, and settle out, form the protective oxide film 3 of oxygen debt state, then can begin to be coated with other retes of low radiation composite film.
The utility model passes through at coat of metal 2; the outside that is the NiCr layer forms the protective oxide film 3 that one deck is in oxygen debt state, and promptly NiCrOx is generally NiCrO; thereby guarantee defencive function layer Ag better, and reduce the reduction of transmittance significantly.
The utility model can be applied in the framework of present various low radiation composite film system, as:
Common single silver low radiation composite membrane framework:
SnO
2/NiCr/Ag/NiCr/?SnO
2/Si3N4；
TxO/?NiCr/Ag/NiCr/?SnO
