Planar toughened vacuum glass welded by using glass solder with edges being sealed by strip borders and groove

Abstract

The invention discloses planar toughened vacuum glass welded by using a glass solder with edges being sealed by strip borders and a groove. The planar toughened vacuum glass is characterized in that upper glass and lower glass are planar ordinary toughened glass or coated toughened glass; the periphery of the upper glass is provided with an edge-sealing strip border; the periphery of the lower glass is provided with an edge-sealing strip border and an edge-sealing groove; the peripheries of the upper glass and the lower glass are welded together through a glass solder, thereby forming an enclosed vacuum layer; one or two layers of support objects are arranged in the vacuum layer; the edge-sealing strip borders and the support objects consist of toughened glass ink and 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 the 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 ...

[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
