Planar toughened vacuum glass welded through metal solder by means of microwaves with edges being sealed by grooves

Abstract

The invention discloses planar toughened vacuum glass welded through a metal solder by means of microwaves with edges being sealed by grooves. The planar toughened vacuum glass consists of upper glass and lower glass, and is characterized in that the periphery of the upper glass is provided with an edge-sealing strip border; the periphery of the lower glass is welded with an edge-sealing groove; 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; one or two layers of support objects are arranged in the vacuum layer; the edge-sealing strip border and the support objects are made by compounding 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 at last; 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 ...

[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 patents related to vacuum glass filed in March and October 2012, the applicant of the present invention used the method of setting edge banding strips around the glass to overcome the main shortcomings in the existing vacuum glass edge banding process, 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 Frames and supports, the second is that when the glass is tempered, the edge banding frame and supports are melted at high temperature, and its height is further reduced
