Embodiment Construction

[0014] Such as figure 1 As shown, the inner anti-seepage layer is placed first, and the inner anti-seepage layer is made of aluminum oxide and water glass mixed with appropriate water in a ratio of 2:1. Next place the glass solder. Finally, the outer anti-seepage layer is applied, and the outer anti-seepage layer is formed by mixing aluminum oxide powder and water glass in a ratio of 2:1. Such as figure 2 As shown, the glass solder is condensed into a solid after being heated and melted, and the volume becomes smaller, and part of the molten glass solder penetrates into the gap between the upper and lower layers of glass. The outer barrier can be easily removed. The anti-seepage layer can also be made of titanium dioxide, glass powder and other inorganic powdery materials, which will not be listed here.

Abstract

The invention relates to a sealing method for vacuum glass periphery, which is characterized in that upper flat glass is smaller than lower flat glass, and glass welding material 3 is arranged on the periphery of the upper flat glass which is over the lower flat glass; outer side of the glass welding material is coated with an external anti-seepage layer 1, so as to prevent the glass welding liquid from flowing out of glass surface. In order to prevent the glass welding liquid from infiltrating inwards too much, an internal anti-seepage layer 2 can also be arranged on the internal side of glass welding material to confine glass liquid to infiltrate inwards. The height of the inside anti-seepage layer concretion is equal to the height of a support.

Description

technical field [0001] The invention belongs to the technical scope of glass vacuum sealing, and in particular relates to a sealing method for the periphery of vacuum glass. Background technique [0002] In the vacuum glass sealing technology, the design of the edge sealing structure is the key technology to ensure that the periphery of the flat vacuum glass is not deformed, does not produce excessive stress, and does not leak air. In Chinese patent ZL94192667.2 "Method for manufacturing vacuum glass windows" Among them, the edge sealing structure is designed so that two pieces of glass are of different sizes, and the low melting point glass solder is placed on the edge steps. The melted glass solder flows into the gap between the glass plates due to capillary phenomenon. This method requires a large amount of solder, and the edges of the vacuum glass are uneven. When the two glasses are installed vertically, the force is uneven, the mechanical strength is not high, and the ...
