Embodiment 1

[0017] Example 1, such as figure 1 Shown is: a metal solder for vacuum glass, comprising a solid strip-shaped body 1, the body 1 is an indium-tin alloy with a thickness of 0.3-0.6 mm and a width of 0.6-1.5 mm. The surface of the body 1 is coated with a nano-light-absorbing material 2, the nano-light-absorbing material 2 is an organic solution of nano-silver, nano-gold or nano-graphene, and the solvent of the organic solution is ethanol. The concentration of nano silver in the organic solution is 0.1%-2%. The body 1 is vacuum plasma cleaned before coating the nano light-absorbing material 2, and the surface contact angle of the body 1 after vacuum plasma cleaning is less than 15°.

[0018] The specific implementation process is as follows: In the production of vacuum glass, metal solder is used for sealing, the metal solder is sandwiched between two pieces of glass, a metallized layer is set on the glass for welding with metal solder, and laser welding is used The method adop...

Embodiment 2

[0019] Embodiment 2. In this embodiment, the nano light-absorbing material is an organic solution of nano gold.

Embodiment 3

[0020] Embodiment 3, in this embodiment, the nano light-absorbing material is an organic solution of nano-graphene.

Abstract

The invention discloses a metal soft solder for vacuum glass in the field of brazing materials. The metal soft solder comprises a solid strip-shaped body, and the surface of the body is coated with a nano light absorption material. According to the invention, the problem that the mechanical strength of the vacuum glass is seriously influenced due to great residual thermal stress existing in the sealing of metal soft solder for the vacuum glass in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of brazing materials, in particular to a metal solder for vacuum glass. Background technique [0002] Vacuum glass is a new generation of energy-saving and environmentally friendly glass. Compared with ordinary single-layer tempered glass, double-layer insulating glass and other glass products that have been widely used, it has obvious product performance advantages. Its advantages are mainly reflected in sound insulation performance, heat insulation performance, heat preservation performance, and anti-condensation function. It has high efficiency and energy-saving effects and reduces environmental pollution in a wide range of fields such as construction, refrigeration, heating, electrical, and transportation. Therefore, it has great potential and application market. [0003] The essence of vacuum glass is that two pieces of ordinary toughened glass are encapsulated by an airtight sealing material. The airtight seali...
