Problems solved by technology
[0003] The technical problem to be solved by the present invention is to provide a convex double-vacuum laminated glass with mounting holes welded to the sealing strip groove edge-sealed glass and its manufacturing method in view of the defects existing in the existing vacuum glass. This vacuum glass and its manufacturing method The process is simple and the production efficiency is high. The prepared tempered vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered characteristics of the tempered glass. It can produce tempered vacuum glass in large quantities and increase its service life.

Abstract
Glass-welded convex double-vacuum-layer glass provided with edges sealed by sealing grooves and sealing strips and provided with mounting hole(s) is disclosed. The convex double-vacuum-layer glass comprises upper glass, lower glass and middle glass, and is characterized in that: the convex double-vacuum-layer glass is provided with the mounting hole(s); the number of the mounting hole(s) is 1-4; the lower surfaces of the upper glass and the middle glass and the periphery of each mounting hole are provided with sealing strips; corresponding positions of the peripheries of the upper surfaces of the middle glass and the lower glass and the mounting hole(s) are provided with the sealing grooves and sealing strips; after the three sheets of glass are rapidly heated, the peripheries of the three sheets of glass and the periphery of each mounting hole are welded under elevated pressure by glass solder in a vacuum furnace; and two vacuum layers are formed among the three sheets of glass. 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 convex double-vacuum-layer glass with sealing strip groove edge sealing glass welded with installation holes 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 ...
