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

Embodiment 1

[0057] Embodiment 1: see figure 1 , the two pieces of tempered vacuum glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass. A through hole is drilled at the corner of the glass 1 to form an air outlet 3, and the upper and lower glasses are edged, chamfered, cleaned, and dried, and the peripheral welding of the upper and lower glasses and the periphery and corresponding parts of the air outlet 3 are passed through the machine with tempered glass ink. Spraying technology to prepare sealing strips 5 and 6; secondly, put two pieces of glass into two forming molds respectively, place the forming molds with glass in a tempering furnace, heat up to the temperature at which the glass softens, and rely on gravity to make the forming molds The glass forms a convex surface downwards, and then it is air-cooled and tempered to obtain tempered or semi-tempered glass; the support is made of a high polymer alone, and the high polymer is polyimide. First, it is...

Embodiment 2

[0058] Example 2: see figure 2 , the upper and lower glass of the double vacuum layer tempered vacuum glass is tempered glass or semi-tempered glass, and the middle glass is low-emissivity glass. The production method is as follows: First, cut three planes of the required size according to the shape and size of the vacuum glass to be produced. Glass, respectively drill a through hole on the upper glass 1 and the middle glass 9 to form the suction port 3, wherein the through hole on the upper glass 1 is larger than the through hole on the middle glass 9, and the three pieces of glass are ground, chamfered, cleaned , drying treatment; secondly, utilize toughened glass ink spraying to prepare sealing strips 5 and 6 at the peripheral welding place of upper glass 1, lower glass 2 and middle glass 9 and the periphery and corresponding positions of air outlet 3, wherein the sealing of the periphery of air outlet 3 The bar contains metal silver powder or / and aluminum powder, etc., an...

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...
