Problems solved by technology

[0003] Although vacuum glass is one of the best energy-saving products, it has not been popularized and applied on a large scale for more than ten years. There are three reasons: first, the existing vacuum glass production process is complicated and the production cost is high, which leads to high market prices and users It is unbearable; second, it is difficult to mechanize and automate production, the production capacity is low, and it is difficult to meet the requirements of users for timely supply; third, it is impossible to produce tempered vacuum glass, which greatly limits the application range of vacuum glass
[0004] In a series of vacuum glass patents filed by the applicant of the present invention in March and October 2012, the main disadvantages of the existing vacuum glass edge sealing process were overcome by setting the edge sealing strip frame at the welding place around the glass, and proposed The production method of tempered vacuum glass has been proposed, but its disadvantage is that it is difficult to achieve the required height of the edge banding frame made of tempered glass ink. The first reason is that the glass does not absorb moisture, so it is difficult to make a higher edge banding The second is that when the glass is tempered, the edge banding frame is melted at high temperature, and its height is further reduced

Embodiment 1

[0047] 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, and its production method is as follows: firstly, a piece of flat glass and a piece of low-emission glass are cut according to the shape and size of the vacuum glass to be produced. For glass, set up edge sealing grooves at the peripheral welding of the lower glass, and perform edge grinding, chamfering, and film removal. After cleaning and drying, use a silk screen to print tempered glass ink into edge sealing strips on the two pieces of glass. And print the silver paste for tempered glass as a transition layer between the upper glass edge band frame and the lower glass edge band frame. After the upper and lower glass are combined, the upper glass edge band frame can be fitted The edge sealing groove of the lower glass; secondly, put the two pieces of glass into two forming molds respectively. The forming mold has an upper ...

Embodiment 2

[0048] 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 two pieces of flat glass of the required size according to the shape and size of the vacuum glass to be produced and For a piece of low-emissivity glass, an edge-sealing groove is set at the upper surface of the middle glass and the lower glass, and the edges are ground, chamfered, cleaned, and dried. The tempered glass ink with aluminum powder is printed into the edge banding frame. The size of the upper edge banding frame is between the lower two edge banding frames. After the upper, middle and lower glass are combined, the upper edge banding frame can be Embedded in the edge sealing groove below; secondly, put the upper and lower pieces of glass into two forming molds respectively, the glass is sandwiched between the upper mold and th...

Abstract

The invention relates to a convex tempered vacuum glass which is microwave-welded by using a metal solder and which is edge-sealed by using bar frames and a groove. The glass is characterized in that upper glass and lower glass are convex common tempered glass or coated tempered glass. An edge-sealing bar frame is provided on the welding periphery of the upper glass; an edge-sealing bar frame and an edge-sealing groove are provided on the welding periphery of the lower glass; the peripheries of the upper glass and the lower glass are welded together by using a metal solder, such that a sealed vacuum layer is formed between the upper glass and the lower glass. The edge-sealing bar frames are prepared by using tempered glass ink and / 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 tempered glass ink; and the pre-polymer is cured into elastomer under room temperature or high temperature. The pre-polymer or the elastomer can be automatically adapted to the changes of vacuum layer height. Volatile gases in the elastomer can be eliminated under high temperature and high vacuum. The method provided by the invention is suitable for mechanized and automated productions. With the method, mass production of tempered vacuum glass with high performance and low cost can be realized.

Description
