Problems solved by technology

In the patent CN94192667.2 "Method for Manufacturing Vacuum Glass Windows", the edge sealing structure is designed so that the upper glass is slightly smaller than the lower glass in the two glasses, and the low melting point glass solder is placed on the edge steps formed by the two glasses, and the melted glass Solder flows into the gap between two pieces of glass due to capillary phenomenon. This method is the most representative and practical edge sealing technology at present, but it has the disadvantages of large amount of solder, uneven edges and high stress; patent CN95108228.0 "vacuum Flat glass and its manufacturing method" and CN96208977.X "vacuum flat glass", the edge of the glass plate is used to "chamfer" first, and the solder is placed in the chamfering groove. This method has the difficulty of distributing and the low-melting point glass solder is heated. Deficiencies that are easily lost during fusing and sealing; the patent CN02256440.3 "vacuum glass edge sealing structure" is to put auxiliary sealing strips on the upper periphery of the lower flat glass to prevent the loss of solder liquid. Although this method solves the problem of solder liquid's outward loss , but the process is complicated, and the auxiliary sealing strip takes up a large space, and it cannot solve the problem that the solder liquid flows into the glass; the edge sealing method of the vacuum glass proposed in the patent CN200620070302.7 "fully transparent vacuum glass" is to make the edge of the glass together with the glass The disadvantage is that the edge banding is not only expensive to manufacture but also cannot restrict the flow of low-temperature solder to the inside of the glass; patent CN200920314752.X "Edge banding structure of vacuum glass" is based on the glass and the The top glass and/or the base glass between the edge of the glass is made with a geometric filling groove, although it can improve the adhesion of the sealing filler between the base glass and the top

Embodiment 1

[0073] Embodiment 1: see figure 1 , the vacuum glass is composed of upper and lower glass, one of which is low-emissivity glass, and its production method is as follows: first, cut a piece of flat glass and a piece of low-emission glass of the required size according to the shape and size of the vacuum glass to be produced, and then perform edge grinding, After chamfering, film removal, cleaning and drying, the low-temperature glass powder paste is printed on the glass to form an edge banding frame by printing technology. The upper glass has one edge banding frame, and the lower glass has two edge banding frames. The size of the upper glass edge seal frame is between the lower glass edge seal frames. After the upper and lower glass are combined, the edge seal frame of the upper glass can be embedded between the edge seal frames of the lower glass; the upper and lower glass are dried Finally, print or spray commercially available silver paste on the position of the edge banding...

Embodiment 2

[0076] Example 2: see figure 2 , one of the two pieces of vacuum glass is low-emissivity glass, and the other is tempered glass or half-tempered glass. Radiation glass, after grinding, chamfering, removing film, after cleaning and drying, use a spray gun to spray low-temperature glass powder paste on two pieces of glass to make an edge banding frame, in which the upper glass has an edge banding frame, the lower glass There are two edge sealing frames, the size of the upper glass edge sealing frame is between the two edge sealing frames of the lower glass, after the upper and lower glass are combined, the edge sealing frame of the upper glass can be embedded Between two edge banding frames; after the upper and lower glass are dried, print or spray a layer of paste containing low-temperature glass powder on the position of the edge banding frame, and then print or spray a layer of commercially available silver paste as a transition layer Next, put the upper glass into the mold...

Embodiment 3

[0080] Embodiment 3: see image 3 , the two pieces of glass of the vacuum glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass, and its production method is as follows: first, 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. , carry out edge grinding, chamfering, film removal, after cleaning and drying, use nylon screen to print low-temperature glass powder paste on two pieces of glass to form an edge banding frame, in which the upper glass has an edge banding frame and the lower glass There are two edge sealing frames, the size of the upper glass edge sealing frame is between the two edge sealing frames of the lower glass, after the upper and lower glass are combined, the edge sealing frame of the upper glass can be embedded Between two edge banding strip frames; secondly, put two pieces of glass into two forming molds respectively, the forming mold has an upper...

Abstract

The invention relates to vacuum glass. The vacuum glass is characterized in that each of upper glass and lower glass is convex surface glass, edge sealing strip frames are arranged at the welded peripheries of the upper glass and the lower glass, and the upper glass and the lower glass are welded together by utilizing metal or alloy solder in a vacuum edge sealing furnace; and the manufacturing of the vacuum glass is simpler and more convenient, and the matching of the upper and the lower edge sealing strip frames can ensure a good sealing effect. The method has the advantages of simpleness in manufacturing process, low cost, high production efficiency, reliability in sealing and connecting and good sealing effect; the one-step large-batch preparation of the vacuum glass without exhaust ports can be realized by utilizing the technology, and the manufactured vacuum glass is strong in resistance to wind pressure and good in heat insulation and sound insulation; and the method can be used for manufacturing the ordinary vacuum glass and is particularly suitable for manufacturing tempered vacuum glass.

Description

technical field [0001] The invention relates to the processing and manufacturing of vacuum glass, in particular to a method for making 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 building doors and windows, glass curtain walls, solar products, agricultural greenhouses, refrigerators and refrigerators, and daily necessities for residents. Soundproofing and finishing materials. In the process of making vacuum glass, the structure and technology of edge sealing is the key technology to ensure that the periphery of vacuum glass is not deformed, does not produce excessive stress, does not leak air, and maintains the characteristics of tempered glass. In the patent CN94192667.2 "Method for Manufacturing Vacuum Glass Windows", the edge sealing structure is designed so that the upper glass is slightly smaller than ...
