Vacuum glass sealing and connecting structure, semi-finished product of vacuum glass sealing and connecting structure, and sealing and connecting method of vacuum glass sealing and connecting structure

Abstract

The invention provides a vacuum glass sealing and connecting structure, a semi-finished product of the vacuum glass sealing and connecting structure, and a sealing and connecting method of the vacuum glass sealing and connecting structure. According to the sealing and connecting method, one surface of a metal strap material is coated with a glass powder slurry, and the surface is bonded with the peripheral surface, to be sealed and connected, of each glass plate; connection as a whole body is realized via heating melting; and the metal strap material on the adjacent glass plates is laminated, and is connected as a whole body via connection and airtight welding. According to the vacuum glass sealing and connecting structure, the periphery surface, to be sealed and connected, of each glass plate is connected with the metal strap material via glass powder slurry heating melting, so that the metal strap material on the adjacent glass plates is laminated, and is connected and subjected to airtight welding According to the vacuum glass sealing and connecting structure, infiltrating characteristics of the glass powder slurry and bonding performance under fusion states are used fully; easy welding characteristics of metal material is used fully; and flow line production of vacuum glass with tempered glass and semi-tempered glass is realized.

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-point glass paste is used to melt and seal between two glass plates. The sealing temperature is generally between 350°C and 450°C. The low-melting-point glass paste is melted by flame or electric heating to complete the glass. A hermetic seal between the plate and the glass plate. The low-melting glass powder slurry used in this process is usually composed of lead-co...

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 much higher than that of glass, while the vacuum chamber of vacuum glass has a large surface area but a small volume, a certain amount of outgassing will make 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
