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] Example 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 The glass is edged, chamfered, and film removed. After cleaning and drying, the tempered glass ink is used to make an edge banding frame on two pieces of glass by screen printing. The upper glass has an edge banding frame and the lower glass has an edge banding frame. Two edge seal frames, the size of the upper glass edge seal frame is between the two edge seal frames of the lower glass. After the upper and lower glass are combined, the edge seal frame of the upper glass can be embedded in the two Between the edge banding strips; secondly, send the two pieces of glass into the tempering furnace and carry out tempering treatment under the same conditions. Under the action of high temperature, the tempered glass ink and glass are...

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 A piece of low-emissivity glass is edged, chamfered, film removed, cleaned and dried, and the tempered glass ink is printed on the joint surface of the three pieces of glass to form an edge band frame by printing technology, and printed on the upper and lower glass at the same time The support, wherein the upper glass has one edge banding frame, the upper surface of the middle glass has two edge banding frames, the lower surface has one edge banding frame, the lower glass has two edge banding frames, and the upper edge banding frame The size is between the two lower edge-seal frames. After the upper, middle and lower glass...

Abstract

The invention relates to glass-solder microwave-welded planar tempered vacuum glass edge-sealed by using bar frames. The glass is characterized in that upper glass and lower glass are common tempered glass or plated tempered glass. Edge-sealing bar frames are provided at the peripheries of the upper glass and lower glass. The peripheries of the upper and lower glass are welded together with microwaves by using a glass solder. A sealed vacuum layer is formed between the upper glass and lower glass. 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 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 adapt to the changes in 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 ...
