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 the glass, set up an edge sealing groove at the peripheral welding place of the lower glass, and perform edge grinding, chamfering, and film removal. After cleaning and drying, use a silk screen to print the tempered glass ink into an edge sealing strip frame on the upper glass, and Silver paste for tempered glass is printed on the upper glass edge banding frame and the lower glass edge banding groove as a transition layer. After the upper and lower glass are combined, the upper glass edge banding frame can be fitted into the lower glass sealing In the side groove; secondly, put two pieces of glass into two forming molds respectively. The for...

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 provided at the upper surface of the intermediate glass and the lower glass, and the edges are ground, chamfered, cleaned, and dried. The tempered glass ink of silver powder and aluminum powder is printed into the edge banding frame, and a transition layer is printed in the edge banding groove. The size of the upper edge banding frame is between the lower edge banding groove. After the sheet is cut, the upper edge banding frame can be fitted into the lower edge banding groove; secondly, put the upper and lower pieces of glass into two forming molds respectively...

Abstract

The invention discloses metal solder and microwave-welded convex toughened vacuum glass with edges being sealed by groove. The convex toughened vacuum glass is characterized in that upper glass and lower glass are convex ordinary toughened glass or coated toughened glass; the welded periphery of the upper glass is provided with an edge-sealing strip border; the welded periphery of the lower glass is provided with an edge-sealing groove; the peripheries of the upper glass and the lower glass are welded together through a metal solder by using microwaves; an enclosed vacuum layer is formed between the upper glass and the lower glass; the edge-sealing strip border is made of toughened glass ink and / or a high polymer; the high polymer is prepared into a prepolymer firstly; after toughening of the glass, the prepolymer is prepared on the toughened glass ink; the prepolymer is cured into an elastomer at a room temperature or a high temperature; the prepolymer or the elastomer can automatically adapt to the height change of the vacuum layer; and the elastomer exhausts contained volatile gas at a high temperature and in high vacuum. Through adoption of a method disclosed by the invention, mechanical and automatic production can be implemented easily, and high-performance and low-cost toughened vacuum glass can be manufactured on a 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 ...
