Planar tempered vacuum glass edge-sealed by using sealing strips and with getter, and preparation method thereof

Abstract

The invention relates to planar tempered vacuum glass which is edge-sealed by using sealing strips and which has 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. Sealing strips are provided at the peripheries of the upper glass and the lower glass. The peripheries of the upper and lower glass are welded together by using a glass solder under normal pressure in an edge-sealing furnace. The air-exhaust port is automatically sealed in a vacuum furnace with the sealing cap and with a metal solder. The getter is automatically activated during the sealing process. A vacuum layer is formed between the upper glass and the lower glass. A supporter is provided in the vacuum layer. The sealing strips and / or the supporter is composed of tempered glass ink and / or a high-polymer. The high-polymer is first prepared into a pre-polymer. After 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 a getter on the sealing edge of a sealing strip 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 out in...

Embodiment 1

[0070] Embodiment 1: see figure 1The vacuum glass consists of upper glass 1 and lower glass 2. The two pieces of glass are tempered glass or half-tempered glass, one of which is low-emissivity glass. The production method is as follows: First, cut the required size according to the shape and size of the vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass, remove the film at the welding part of the low-emissivity glass, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and perform edge grinding, chamfering, cleaning and drying on the upper and lower glass , use screen printing technology to print the sealing strip on the peripheral welding of the upper and lower glasses and print the support 8 on one of the glasses at the same time; secondly, send the two pieces of glass into the tempering furnace for air-cooled tempering to obtain tempered or semi-tempered Glass; at the same time prepare high polymer 12, high polyme...

Embodiment 2

[0071] Example 2: see figure 2 , the vacuum glass is made up of upper glass 1, middle glass 9 and lower glass 2. Among the three pieces of glass, at least the upper and lower glasses are tempered glass or semi-tempered glass, and at least one piece of glass is still low-emissivity glass. The manufacturing method is as follows: first According to the shape and size of the vacuum glass to be produced, cut three pieces of flat glass of the required size, drill a through hole on the upper glass 1 and the middle glass 9 respectively to form the air suction port 3, wherein the through hole on the upper glass 1 is larger than the middle glass 9, and perform edge grinding, chamfering, cleaning, and drying on the three pieces of glass; secondly, use tempered glass ink to print the sealing strip 5 and 6. Print the support 8 on the lower surface of the upper glass 1 and the upper surface of the lower glass 2, send the middle glass 9 into a high-temperature furnace for high-temperature t...
