Problems solved by technology

Due to the small space in the vacuum layer of vacuum glass and the transparency of the glass, the protection and activation of the getter needs to be considered, so it is very difficult to place the getter in the vacuum layer
The traditional method of placing the getter in the vacuum glass is to first package the getter under vacuum, and then place it in the groove pre-opened on the glass....

Embodiment 1

[0069] Embodiment 1: see figure 1, the two pieces of tempered vacuum glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass. A tapered through hole is drilled at the corner of the glass 1 to form an air outlet 3, and the upper and lower glasses are ground, chamfered, cleaned and dried, and the sealing strip 5 is prepared by mechanical spraying technology using tempered glass ink on the peripheral welding of the upper and lower glasses and 6; followed by putting two pieces of glass into two forming molds respectively, placing the forming mold with glass in a tempering furnace, raising the temperature to the temperature at which the glass softens, and relying on gravity to make the glass in the forming mold downwardly form a convex surface, Immediately carry out air-cooling and tempering to obtain tempered or semi-tempered glass; the support 8 is made of high polymer 12 alone, and the high polymer 12 is polyimide. First, pyromellitic dianhydride an...

Embodiment 2

[0070] Example 2: see figure 2 , the upper and lower glass of the double vacuum layer tempered vacuum glass is tempered glass or semi-tempered glass, and the middle glass is low-emissivity glass. The production method is as follows: First, cut three planes of the required size according to the shape and size of the vacuum glass to be produced. Glass, respectively drill a through hole on the upper glass 1 and the middle glass 9 to form the suction port 3, wherein the through hole on the upper glass 1 is larger than the through hole on the middle glass 9, and the three pieces of glass are ground, chamfered, cleaned , drying treatment; secondly, the sealing strips 5 and 6 are prepared by tempered glass ink spraying at the peripheral welding places of the upper glass 1, the lower glass 2 and the middle glass 9, and the middle glass 9 is directly sent into a high-temperature furnace for high-temperature treatment, and the upper and lower two Put a piece of glass into the mold, hea...

Abstract

Convex tempered vacuum glass provided with a getter in edge sealing of sealing strips is disclosed. The convex tempered vacuum glass is characterized in that: upper glass and lower glass are convex tempered glass; the upper glass is provided with an extraction opening; the extraction opening is provided with a sealing cover; the getter is disposed in the extraction opening; the periphery of the upper glass and the periphery of the lower glass are provided with the sealing strips; the periphery of the upper glass and the periphery of the lower glass are welded by adoption of low-temperature glass solder at normal pressure in an edge banding furnace; the extraction opening is automatically sealed by utilization of the sealing cover and metal solder in a vacuum furnace; the getter is automatically activated in a sealing process; a closed vacuum layer is formed between the upper glass and the lower glass; the sealing strips are made of tempered glass printing ink and/or polymer; the polymer is prepared into pre-polymer firstly, and then the prepolymer is prepared onto glass or tempered glass printing ink after glass tempering; the prepolymer cures at the room temperature or high temperature to form an elastomer; the prepolymer or the elastomer can automatically adapt to changes of the height of the vacuum layer; and volatile gas in the elastomer is removed at a high temperature and under high vacuum.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a convex tempered vacuum glass with a getter on the sealing edge of a sealing strip and a manufacturing method thereof. Background technique [0002] Vacuum glass is a new type of energy-saving glass. Vacuum glass can not only solve the "breathing" problem of insulating glass used in large quantities, but also has good heat and sound insulation performance, high wind pressure resistance, small thickness and long service life. advantage. Vacuum glass is generally composed of two to three pieces of glass, a cavity is formed between two adjacent pieces of glass, and an edge sealing structure is arranged around the glass, and the cavity is evacuated to form a vacuum layer. Vacuum glass can be divided into two types according to the way of forming the vacuum layer. One is the vacuum glass without air extraction port. The edge sealing of this vacuum glass is carried out ...
