Flat tempered vacuum glass welded by metal solder and edge-sealed with groove

Abstract

A flat tempered vacuum glass welded by a glass solder and edge-sealed through a groove is composed of an upper glass and a lower glass and is characterized in that a periphery of the upper glass is provided with an edge-sealing bar frame and the periphery of the lower glass is provided with an edge-sealing groove. The peripheries of the upper glass and the lower glass are welded to each other through the metal solder. A sealed vacuum layer, with a supporting object therein, is formed between the upper glass and the lower glass, wherein the supporting object includes one layer or two layers. The edge-sealing bar frame and the supporting object are manufactured from tempered glass printing ink and a high polymer in a composite manner. 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. Finally 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. The method is easy to mechanize and automate and can be used for manufacturing the tempered vacuum glass with high performance and low cost in large scale.

Description

technical field [0001] The invention relates to the processing and manufacturing of vacuum glass, in particular to a method for making tempered vacuum glass and its products. Background technique [0002] Vacuum glass is a new type of energy-saving and environmentally friendly product, which can be widely used in industrial and agricultural fields such as buildings and vehicle and ship doors and windows, glass curtain walls, solar products, agricultural greenhouses, refrigerators and refrigerators, and daily necessities for residents. Thermal insulation, sound insulation and decorative materials. [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 ...

[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 patents related to vacuum glass filed in March and October 2012, the applicant of the present invention used the method of setting edge banding strips around the glass to overcome the main shortcomings in the existing vacuum glass edge banding process, 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 Frames and supports, the second is that when the glass is tempered, the edge banding frame and supports are melted at high temperature, and its height is further reduced
