Vacuum glass sealing structure, semi-finished product and sealing method thereof

Abstract

The invention provides a vacuum glass sealing structure, a semi-finished product and a sealing method thereof. The sealing method is to coat one side of a metal strip with a glass frit slurry, and then coat the metal strip with the glass frit slurry One side is pasted on the peripheral surface of each layer of glass plates, heated and melted to connect as a whole, and then the metal strips on adjacent glass plates are joined on the outside of the peripheral surfaces and airtightly welded as a whole. The vacuum glass sealing structure is to heat and melt the metal strips on the peripheral surface of each layer of glass plates through glass frit paste, and the metal strips on adjacent glass plates are joined and airtightly welded on the outside of the peripheral surfaces . The invention not only makes full use of the wetting characteristics of glass powder slurry and the bonding ability in molten state, but also makes full use of the easy-welding characteristics of metal materials, so that the flow-through production of vacuum glass by tempered glass and half-tempered glass becomes a reality feasible.

Description

technical field [0001] The invention relates to a vacuum glass sealing structure and method. Background technique [0002] Vacuum glass, which is formed by laminating two or more glass plates, has attracted people's attention for its excellent sound insulation, heat insulation, and thermal insulation properties, and has become the research direction of many companies and individuals. [0003] The sealing methods that may be used in the process of making vacuum glass introduced in the current patent technology mainly include: [0004] (1) A vacuum glass sealing method as attached figure 1 As shown, low-melting glass frit paste is used to melt and seal between two glass plates. The sealing temperature is generally between 350°C and 450°C. Complete the hermetic sealing between the glass plates. The low-melting glass powder slurry used in this process is usually composed of lead-containing or lead-free glass powder. The lead component in it is harmful to the environment and h...

AI Technical Summary

Problems solved by technology

Due to the infiltration and melting process of glass powder slurry, this sealing method is reliable in sealing; but its processing equipment and process are complicated, and because the two glass plates to be packaged enter the heating state at the same time, it is easy to cause the glass plate after packaging There is packaging stress in the vacuum glass, which is unfavorable to the long-term stable use of the finished product. There are still many technical difficulties to be overcome in the vacuum packaging of tempered glass or semi-tempered glass plates. At present, the representative patents of this vacuum glass sealing method are as follows: Invention patent No. CN94192667.2

[0005] (2) A vacuum glass sealing method as attached figure 2 As shown, various resin materials and film materials for making laminated glass are used as the sealing material between glass plates. The process technology is similar to that of laminated glass. However, the gas permeability and outgassing rate of this kind of resin and film materials are far greater than those of glass. Although the vacuum chamber of vacuum glass has a large surface area, its volume is small, and a certain amount of outgassing will make it The vacuum degree in the vacuum chamber is extremely bad, and even loses vacuum; therefore, the long-term stability of vacuum glass products made by this sealing method will be a problem. At present, the representative patent of this vacuum glass sealing method is as follows: Invention patent No. CN02205234.8
