Description
Technical Field
The invention relates to the field of brazing materials, in particular to a metal soft solder for vacuum glass.
Background
The vacuum glass is a new generation of energy-saving and environment-friendly glass, and has obvious product performance advantages compared with commonly used glass products such as common single-layer toughened glass, double-layer hollow glass and the like.

The vacuum glass is essentially formed by packaging two pieces of common toughened glass through an airtight sealing material, wherein the airtight sealing mostly adopts low-temperature glass powder or flexible metal soft solder, a vacuum layer with the thickness of 0.3-0.4 mm is formed between the two pieces of glass through vacuum, and metal supports are arranged between the two pieces of glass in an array manner to offset atmospheric pressure. In the existing flexible metal soft solder sealing technology, a metalized layer is formed on the surface of glass, and then the flexible metal soft solder is heated between the metalized layers of two pieces of glass in various modes such as electromagnetic induction, infrared or integral heating, so that the flexible metal soft solder and the metalized layer are combined to complete sealing. However, since the metal and the glass are not welded by the same material, and additional material is added to the sealing layer, the components of the sealing layer are complex, the thermal expansion coefficients of the layers of the sealing material are not matched, and a large residual thermal stress is generated in the heating and cooling processes of the sealing treatment, which seriously affects the mechanical strength of the vacuum glass.
