Microwave-welded planar tempered vacuum glass edge-sealed by using sealing strips and a sealing groove and provided with getter

Abstract

The invention relates to microwave-welded planar tempered vacuum glass which is edge-sealed by using sealing strips and a sealing groove and which is provided with a getter. The glass is characterized in that upper glass and lower glass are planar tempered glass. An air-exhaust port is provided on the upper glass. A sealing cap is provided on the air-exhaust port. The getter is placed in the air-exhaust port. A sealing strip is provided on the upper glass, and sealing strips and a sealing groove are provided on the lower glass. The upper glass and the lower glass are welded together by using a glass solder under normal pressure in a microwave oven. The air-exhaust port is automatically sealed by using the sealing cap and with a metal solder in a vacuum furnace. The getter is automatically activated during the port-sealing process. A vacuum layer is formed between the upper glass and the lower glass. Supporters are provided in the vacuum layer. The sealing strips and the supporters are prepared by using tempered glass ink or a high-polymer. The high-polymer is first prepared into a pre-polymer. When the glass is tempered, the pre-polymer is prepared on the glass or on the tempered glass ink. The pre-polymer is cured into elastomer under room temperature or high temperature. The pre-polymer or elastomer can be automatically adapted to the changes in the height of the vacuum layer. Volatile gases in the elastomer can be eliminated under high temperature and high vacuum.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat tempered vacuum glass with getters on the edges of grooves sealed by microwave welding sealing strips 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 gla...

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.
