Planar tempered vacuum glass microwave-welded by using metal solder and edge-sealed by using bar frames and groove

Abstract

The invention relates to a planar 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 planar tempered glass. An edge-sealing bar frame is provided on the periphery of the upper glass; an edge-sealing bar frame and an edge-sealing groove are provided on the 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. One or two layers of supporters are provided in the vacuum layer. The edge-sealing bar frames and the supporters are composed of tempered glass ink and 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

Technical field [0001] The invention relates to the processing and manufacturing of vacuum glass, in particular to a manufacturing method of tempered vacuum glass and its products. Background technique [0002] Vacuum glass is a new type of energy-saving and environmentally-friendly products, which can be widely used in buildings, doors and windows of vehicles and ships, glass curtain walls, solar products, agricultural greenhouses, refrigerators, refrigerators and other industrial and agricultural fields and residents’ daily necessities. It is excellent Heat insulation, sound insulation and decoration materials. [0003] Although vacuum glass is one of the best energy-saving products, it has not been promoted 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, resulting in high market prices. It is difficult to bear; second, it is difficult to mechanize a...

[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
