Convex toughened vacuum glass provided with getter with edges being sealed by sealing strips and sealing grooves and manufacturing method thereof

Abstract

The invention discloses convex toughened vacuum glass provided with a getter with edges being sealed by sealing strips and sealing grooves. The convex toughened vacuum glass is characterized in that upper glass and lower glass are convex toughened glass; the upper glass is provided with an extraction opening; a sealing cover is arranged on the extraction opening; the getter is put into the extraction opening; the upper glass is provided with the sealing strips; the lower glass is provided with the sealing strips and the sealing grooves; the upper glass and the lower glass are welded together in an edge-sealing furnace under a normal pressure by using a glass solder; the extraction opening is automatically enclosed in a vacuum furnace by using the sealing cover and a metal solder; the getter is automatically activated in an edge-sealing process; an enclosed vacuum layer is formed between the upper glass and the lower glass; the sealing strips are made of toughened glass ink or/and a high polymer; the high polymer is prepared into a prepolymer firstly; after the glass is toughened, the prepolymer is prepared on the glass or the toughened glass ink; the prepolymer is cured into an elastomer at a room temperature or a high temperature; the prepolymer or the elastomer can automatically adapt to the height change of the vacuum layer; and the elastomer exhausts own contained volatile gas at a high temperature and in 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 groove 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 exhaust 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.
