Embodiment Construction

[0041] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] Figure 2A , Figure 2B is a schematic diagram of the metal edge sealing structure of the vacuum glass of the present invention, wherein Figure 2A An example diagram of the platform sealing structure, Figure 2B It is an example diagram of the staggered sealing structure. In these two structures, a layer of metal transition layer 201 is first solidified on the sealing surfaces of the two flat glass original sheets 101, and then a low-melting-point metal solder 202 is used for fusion welding and sealing between the two metal transition layers 201. Thereby forming a sealed structure of vacuum glass.

[0043] Specifically, in Figure 2A In the sealing structure of the platform shown, the two flat glass original sheets 101 are aligned and placed at the edge, and at the sealing place around the edges of the two glasses, on the lower su...

Abstract

Belonging to the field of vacuum glass and its edge-sealing technologies, the invention relates to a vacuum glass with a metal edge-sealing structure and a making method thereof. The vacuum glass comprises two flat glass sheets, a plurality of supports and a sealing layer. A metal transition layer is respectively cured on a sealing surface of the two flat glass sheets, and the two metal transition layers are fused and sealed by a metal layer formed by a low-melting-point metal welding material, and the fused and sealed metal transition layers and the metal layer form the low-melting-point metal sealing layer. The technical scheme involved in the invention not only can realize convenient and low-cost metal edge-sealing of vacuum glass, is easy to realize large-scale production, but at the same time also can realize low temperature (130DEG C-400DEG C) sealing of vacuum glass and lead-free manufacturing. Therefore, the vacuum glass and the method provided by the invention have great significance in reducing the production cost of vacuum glass and broadening the application scope of vacuum glass.

Description

technical field [0001] The invention belongs to the technical field of glass deep processing, and relates to a vacuum glass, in particular to a vacuum glass structure formed by airtightly sealing glass edges with metal materials. Background technique [0002] Vacuum glass is a glass product with excellent thermal insulation, which has been widely used in the fields of building doors and windows, curtain walls and home appliances. [0003] Earlier, people used silicone structural glue, PC, PVB, SGP and other polymer organic polymer materials to seal glass. Although this type of material has good bonding and sealing properties with glass, for vacuum glass that requires a long-term high vacuum, this type of material obviously cannot be used for vacuum glass hermetic sealing, because this type of organic material has relatively strong The high gas leakage rate will also release gas during use, so that the vacuum degree of the vacuum glass will drop sharply in a short period of ...
