Microwave-welded planar toughened vacuum glass provided with extraction opening with edges being sealed by sealing strips

Abstract

The invention discloses microwave-welded planar toughened vacuum glass provided with an extraction opening with edges being sealed by sealing strips. The planar toughened vacuum glass is characterized in that upper glass and lower glass are planar toughened glass; the upper glass is provided with the extraction opening; the sealing strips are arranged on the peripheries of the upper glass and the extraction opening, the periphery of the lower glass and corresponding positions of the extraction opening; the peripheries of the upper glass and the lower glass are welded together in a microwave oven under the normal pressure by using a low-temperature glass solder; the extraction opening is automatically enclosed in a vacuum furnace by using a metal solder; an enclosed vacuum layer is formed between the upper glass and the lower glass; support objects are arranged in the vacuum layer in a lattice form; the sealing strips and / or the support objects consist of toughened glass ink and / or a high polymer; the high polymer is prepared into a prepolymer firstly; after toughening of the glass, the prepolymer is prepared on the glass or the toughened glass ink; the prepolymer is cured into an elastomer at the 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 room temperature and in 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 microwave welding sealing strip edge sealing and an air suction port 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 gl...

Problems solved by technology

[0003] The applicant of the present invention disclosed a series of vacuum glass without air extraction port and its manufacturing method in the patent of vacuum glass applied in March 2012, but when using low-temperature glass solder to seal the edge, because the low-temperature glass solder is made of various oxidized At high temperature and vacuum, the air and moisture absorbed by the solder, the volatile substances in the solder, the gas dissolved in the solder during the production process, and the decomposition of some oxides in the solder will cause a large number of bubbles in the solder , which greatly weakens the performance of the solder, especially the airtightness, which greatly affects the feasibility of this method

The existing mass-produced vacuum glass is all vacuum glass with an air extraction port, but there are complex manufacturing processes, low air extraction temperature (incomplete air extraction), single-piece vacuuming, high cost, low production capacity, and inability to make toughened vacuum glass. Cons of glass etc.

In addition, it is difficult to achieve the required height for sealing strips and supports made of low-temperature glass powder or low-temperature glass solder. When tempering, the sealing strip and the support are melted at high temperature, and its height is further reduced
