High-temperature-sheet-combination sealed convex vacuum glass with edges sealed by sealing strips and manufacturing method thereof

Abstract

High-temperature-sheet-combination sealed convex vacuum glass with edges sealed by sealing strips is disclosed. The convex vacuum glass comprises upper glass and lower glass which are convex glass. The upper glass is provided with one to four air extracting holes. The peripheries of the upper glass and each air extracting hole are respectively provided with at least one sealing strip. The periphery of the lower glass is provided with at least two sealing strips. A position on the lower glass, which is corresponding to each air extracting hole, is provided with at least one sealing strip. The sealing strip of the upper glass is inserted between or into the sealing strips of the lower glass. After being rapidly heated, the upper glass and the lower glass are subjected to sheet combination at a high temperature, and the peripheries of the upper glass and the lower glass are welded under elevated pressure by glass solder in a heating furnace. Each air extracting hole is automatically sealed by utilization of 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 vacuum glass eliminates edge sealing stress and maintains tempered characteristics of tempered glass. 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 vacuum glass with a high-temperature laminated sealing strip for edge sealing 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 tim...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of convex vacuum glass with high-temperature laminated sealing strip edge sealing and its manufacturing method in view of the defects existing in the existing vacuum glass. High efficiency, the prepared vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered characteristics of tempered glass, can produce tempered vacuum glass in large quantities, and can increase its service life
