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

[0045] 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 glass, set up edge sealing grooves at the peripheral welding of the lower glass, and perform edge grinding, chamfering, and film removal. After cleaning and drying, use a silk screen to print tempered glass ink on the upper glass to form an edge sealing strip frame. After the glass is combined, the edge sealing strip frame of the upper glass can be fitted into the edge sealing groove of the lower glass; secondly, the two pieces of glass are respectively put into two forming molds, the forming mold has an upper mold and a lower mold, and the glass It is sandwiched between the upper mold and the lower mold, and can be pressed to close the upper...

Embodiment 2

[0046] 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 set at the upper surface of the intermediate glass and the lower glass, and the edge is ground, chamfered, cleaned, and dried, and the tempered glass is tempered by printing technology The edge banding frame is printed with glass ink, 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. The side strip frame can be fitted into the edge sealing groove below; secondly, put the upper and lower pieces of glass into two forming molds respectively, the glass is sandwiched betwe...

Abstract

A convex tempered vacuum glass welded by a glass solder through microwave and edge-sealed through a groove is characterized in that upper glass and lower glass are convex common tempered glass or convex film-coated tempered glasses. Welding periphery of the upper glass is provided with an edge-sealed bar frame and the welding periphery of the lower glass is provided with an edge-sealed groove. Peripheries of the upper glass and the lower glass are welded to each other through a glass solder by the microwave. A sealed vacuum layer is formed between the upper glass and the lower glass. The edge-sealed bar frames are manufactured from tempered glass printing ink and / or a high polymer. The high polymer is firstly prepared into a pre-polymer. The pre-polymer, after the glass being tempered, is manufactured on the tempered glass printing ink. The pre-polymer is solidified to form an elastomer at room temperature or a high temperature. The pre-polymer or the elastomer can automatically adapt with change of height of the vacuum layer. Volatile gas in the elastomer is exhausted from the elastomer at a high temperature and a high vacuum degree. The method is easy to be mechanized and automate and can be used for manufacturing the tempered vacuum glass with high performance and low cost in 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 ...
