Metal-welded plain vacuum glass provided with edges sealed by sealing strips and manufacturing method thereof

Abstract

Metal-welded plain vacuum glass provided with edges sealed by sealing strips is disclosed. The plain vacuum glass comprises upper glass and lower glass, and is characterized in that: the upper glass is provided with at least one sealing strip; the periphery of the lower glass is provided with at least two sealing strips; the sealing strip of the upper glass is inserted between the sealing strips of the lower glass; and after being rapidly heated, the upper glass and the lower glass are subjected to sheet combining at a high temperature, and the peripheries of the upper glass and the lower glass are welded under elevated pressure by metal solder in a vacuum furnace. The vacuum glass and a manufacturing method thereof are simple in process and high in production efficiency. The manufactured tempered vacuum glass eliminates edge sealing stress and maintains tempered characteristics of tempered glass. The tempered vacuum glass can be produced in a large scale, and the service lifetime of the tempered vacuum glass can be prolonged.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat vacuum glass welded with sealing strip and edge-sealing metal and a manufacturing method thereof. Background technique [0002] As a new type of glass with the most energy-saving potential, vacuum glass has achieved large-scale production after more than ten years of research and development, and has been well applied in many fields, especially in the construction field; but there are also obvious The shortcomings are mainly low production efficiency, small production capacity, and inability to produce tempered vacuum glass, etc., which limit its popularization and application in a wider range; the existing large-scale production of vacuum glass uses high temperature (430-480°C) normal pressure The production process of lower edge sealing, low temperature (180-300°C) vacuuming and sealing, because it needs to be kept warm for a period of time at the edge seal...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a flat vacuum glass and its production method with sealing strip and edge metal welding for the defects of existing vacuum glass. This vacuum glass and its production method have simple process and high production efficiency , the prepared tempered vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered properties of the tempered glass, can produce tempered vacuum glass in large quantities, and can increase its service life
