Embodiment

Further specify the utility model below in conjunction with accompanying drawing.

With the double-layer structure vacuum glass that is made up of two glass sheets is example; The structure of the utility model vacuum glass such as Fig. 2, shown in Figure 3; Comprise that glass sheets 1, two glass sheets periphery is provided with intermediate supports 3 arrays through the hermetic seal of sealing-in limit between two glass sheets of inboard, sealing-in limit up and down; A bight of the vacuum space 4 in vacuum glass is provided with getter film 6; This getter film 6 is made up of nonevaporable getter, as, can adopt to mainly contain the getter that effective constituent is Zr-V-Fe alloy or Ti-Zr-V alloy or Zr-Al alloy.

The preparation process of the getter film 6 of glass pane surface is in the utility model vacuum glass:

3) in vacuum environment, slurry coating is heated, remove the organic adhesive composition in the slurry coating, make the getter powder in the slurry coating bond to glass pane surface, form the getter film through low glass powder.

Because getter film 6 is through adding thermosetting, thereby when being heated film forming, getter also is activated.

Exactly because also in the film forming while of getter, also be activated, therefore, in order to keep the air-breathing usefulness of getter, the heating film forming needs in vacuum environment, to carry out.

The effect of the low glass powder in the slurry is to be used for getter powder (particle) glass pane surface that is adhesively fixed, thereby the content of low glass powder can be tested definite.

The effect of organic adhesive is to guarantee that slurry can form coating in glass pane surface, and when slurry coating is heated, also wants and can remove smoothly, thereby the kind of organic adhesive, the content in slurry, all can confirm through test.
