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 glass 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 vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the toughened characteristics of tempered glass, which can be mass-produced and can increase its service life

Embodiment

[0036] Example: Refer to the attached drawings. The plane vacuum glass is composed of upper glass 1 and lower glass 2. The two glasses are tempered glass or semi-tempered glass, and one of them is low-e glass. The manufacturing method is as follows: Cut a piece of flat glass and a piece of low-e glass of the required size of the shape and size. Choose low-e glass as the lower glass 2. Open a sealing groove 6 at the peripheral welding of the lower glass 2, and perform edge grinding, chamfering, cleaning, and drying , The sealing strip is printed on the periphery of the upper glass 1 and the periphery of the upper sealing groove 6 of the lower glass 2 by screen printing technology and the support 3 is printed on at least one piece of glass at the same time; secondly, the two pieces of glass are sent into the tempering furnace Air-cooled tempering is performed in the process to obtain tempered or semi-tempered glass; again, the sealing groove 6 around the lower glass 2 is evenly co...

Abstract

Glass-welded plain vacuum glass 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 upper glass is provided with sealing strips; the periphery of the lower glass is 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 glass 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 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 flat vacuum glass welded by sealing strip groove edge sealing glass 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 the construction field; but there are also obvious The shortcomings are mainly low production efficiency, low production capacity, and inability to produce toughened vacuum glass, which limits its promotion and application in a wider range; the existing large-scale production of vacuum glass uses high temperature (430-480°C) atmospheric pressure The production process of under-sealing and low-temperature (180-300℃) vacuuming and then sealing. Because the edge-sealing temperature needs to be kept for a period of time, gener...
