Problems solved by technology

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

Embodiment

[0041] Embodiment: Referring to the accompanying drawings, the flat vacuum glass is composed of an upper glass 1 and a lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, and one of them is a low-emissivity glass. The manufacturing method is as follows: Cut a piece of flat glass and a piece of low-emissivity glass according to the shape and size of the required size, select the low-emissivity glass as the lower glass 2, set up a sealing groove 4 at the corresponding position around the lower glass 2, and perform edging, chamfering, cleaning and drying , use screen printing technology to print the sealing strip on the periphery of the upper glass 1 and the periphery of the sealing groove 4 on the lower glass 2 and at the same time print the support 8 on at least one piece of glass, and then make the sealing strip and the surface of the sealing groove Silver paste layer 6; secondly, two pieces of glass are sent into a tempering furnace for air-coolin...

Abstract

Metal-welded plain vacuum glass provided with edges sealed by sealing grooves and sealing strips is disclosed. The plain vacuum glass comprises upper glass and lower glass, and is characterized in that: the periphery of the upper glass is provided with sealing strips; corresponding positions of the periphery of the lower glass are provided with the sealing grooves and sealing strips; 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; a sealed vacuum layer is formed between the upper glass and the lower glass; and supports arranged in a point array are disposed in the vacuum layer. 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 plane vacuum glass welded with sealing strip groove 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 ...
