Convex tempered vacuum glass provided with getter in edge sealing of sealing strips and preparing method thereof

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 ...

AI Technical Summary

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. After sealing the edge of the vacuum glass, vacuuming, and sealing the suction port , and then use laser or infrared rays to open the package of the getter to activate the getter. The disadvantage of this method is that the encapsulation and placement process of the getter is complicated, the amount of the getter is small, and the appearance and mechanical properties of the glass are affected.
