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

[0044] Embodiment 1: see figure 1 , Tempered vacuum glass is composed of two pieces of tempered glass or semi-tempered glass, one of which is low-emissivity glass, and its production method is as follows: First, cut a flat glass and a piece of low-emission For glass, edge sealing grooves are set at the peripheral welding of the lower glass, and edge grinding, chamfering, and film removal are performed. After cleaning and drying, tempered glass ink is used to make edge sealing strips on the two pieces of glass by screen printing, of which There is one edge banding frame for the upper glass, and two edge banding frames for the lower glass. The size of the edge banding frame of the upper glass is between the two edge banding frames of the lower glass. The side strip frame can be fitted in the edge sealing groove between the two edge strip frames of the lower glass; secondly, the two pieces of glass are sent into the tempering furnace and tempered under the same conditions, and th...

Embodiment 2

[0045] 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, set up edge sealing grooves at the upper surface of the middle glass and the lower glass, and perform edge grinding, chamfering, and film removal. After cleaning and drying, use printing technology to print The tempered glass ink is printed into the edge banding frame, and the support is printed on the upper and lower glass at the same time. The upper glass has an edge banding frame, and the upper surface of the middle glass has two edge banding bars. The lower surface of the frame has an edge banding strip The frame and the lower glass have two edge-seal frames, the size of the upper e...

Abstract

The invention relates to glass-solder microwave-welded planar tempered vacuum glass with the 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 with a glass solder by using microwave, 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. 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 of the height of the vacuum layer. 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 productions of high-performance and low-cost tempered vacuum glass can be realized.

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 ...
