Convex tempered vacuum glass edge-sealed with sealing bars and having vacuumizing hole and manufacturing method thereof

Abstract

A convex tempered vacuum glass edge-sealed with sealing bars and sealing groove and having a vacuumizing hole is characterized in that an upper glass and a lower glass are convex tempered glass. A vacuumizing hole is formed in the upper glass. Peripheries of the upper glass and the vacuumizing hole are provided with the sealing bars and the periphery of the lower glass and positions corresponding to the vacuumizing hole are provided with the sealing bars. The peripheries of the upper glass and the lower glass are welded to each other in an edge-sealing oven at a normal pressure through a low-temperature glass solder. The vacuumizing hole is automatically sealed in a vacuum oven through a metal solder. A sealed vacuum layer is formed between the upper glass and the lower glass. The edge-sealing bar is manufactured from tempered glass printing ink and / or a high polymer. The high polymer is firstly prepared into a pre-polymer. The pre-polymer, after the glass being tempered, is manufactured on the glass or the tempered glass printing ink. The pre-polymer is solidified to form an elastomer at room temperature or a high temperature. The pre-polymer or the elastomer can automatically adapt with change of height of the vacuum layer. Volatile gas in the elastomer is exhausted from the elastomer at a high temperature and a high vacuum degree.

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 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 glass is carried...

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
