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. Glass, and carry out edge grinding, chamfering, film removal, after cleaning and drying, use silk screen to print tempered glass ink into edge banding frame on two pieces of glass, and print on the upper and lower edge banding frame of the upper glass The tempered glass is printed with silver paste between the two edge banding frames of the glass as a transition layer. After the upper and lower glass are combined, the edge banding frame of the upper glass can be embedded between the edge banding frames of the lower glass; The two pieces of glass are respectively loaded into two forming molds, the forming mold has an upper mold and a lower mold, t...

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 A piece of low-emissivity glass is ground, chamfered, cleaned, and dried. Use printing technology to print tempered glass ink containing silver powder and aluminum powder into an edge banding frame around the welding surface of the upper, middle and lower glass. The size of the edge banding frame is between the two lower edge banding frames. After the upper, middle and lower glass are combined, the upper edge banding frame can be fitted between the lower edge banding frames; secondly, the upper and lower glass Put the glass into two forming molds respectively, and the glass is clamped between the upper mold and the lower m...

Abstract

The invention discloses convex toughened vacuum glass welded through a metal solder by means of microwaves with edges being sealed by strip borders. The convex toughened vacuum glass is characterized in that upper glass and lower glass are convex ordinary toughened glass or coated toughened glass; the welding peripheries of the upper glass and the lower glass are provided the edge-sealing strip borders; the peripheries of the upper glass and the lower glass are welded together through the metal solder by means of microwaves; an enclosed vacuum layer is formed between the upper glass and the lower glass; the edge-sealing strip borders are 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 glass or 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 own 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 ...
