Example Embodiment

[0044] The present invention will be further described below in conjunction with accompanying drawing.

[0045] When making vacuum glass according to the sealing method of the present invention, first, prepare a metal layer solidified with the glass plate on the surface to be sealed at the edge of the glass plate, the metal layer is made of metal foil, and is welded on the glass by ultrasonic welding. On the board surface, the prepared metal layer 1 as figure 1 shown in; Then, press the two glass plates 2 and 3 to be sealed figure 2 The state shown is compounded, and metal brazing solder is arranged between the two corresponding metal layers 1 on the two glass plates 2 and 3; finally, the metal brazing process is used to directly connect the two corresponding metal layers on the two glass plates. The metal layers 1 are airtightly welded to each other to realize the airtight sealing of the edges of the two glass plates.

Abstract

The invention discloses a vacuum glass sealing method which comprises the following steps: preparing a metal layer, which is bonded with a glass plate, on the surface of the glass plate by an ultrasonic welding technique; and carrying out hermetic seal on the edges of the two glass plates by a metal brazing technique, or carrying out hermetic welding on the metal layers of the two glass plates to be sealed so as to connect the metal seal sheets, thereby implementing hermetic seal on the edges of the two glass plates. The ultrasonic welding technique is utilized to arrange the metal layer on the surface of the glass plate, and the welding technique is utilized to carry out hermetic seal on the edges of the two glass plates on the basis of the metal layer, thereby providing a new technical way for manufacturing vacuum glass. The tempered vacuum glass manufactured by the method disclosed by the invention has the advantages of firm connection of the seal position, high air tightness, favorable thermal shock resistance and the like; and the seal structure formed by the metal seal sheets can well adapt to the temperature deformation of the inner and outer glass plates in the vacuum glass due to temperature difference, thereby providing technical guarantee for safe application of the vacuum glass.

Description

technical field [0001] The invention relates to a vacuum glass sealing method and its products. Background technique [0002] Vacuum glass, which is composed of multiple glass plates, has attracted people's attention due to its excellent sound insulation, heat insulation, and thermal insulation properties, and has become a subject of intense research. [0003] Earlier, people used various plastic or resin materials to seal the edges of glass plates to make vacuum glass. For example, some patent documents mention the use of PC, ABS, LDPE, PVC and other plexiglass as sealing materials, and some patent documents use laminated glass materials such as PVB and EVA (EN), and the processing methods are to use the above materials After being placed between two glass plates, it is made into a prefabricated part together with the glass plate, and then the prefabricated part is placed under appropriate conditions for pressing to realize the sealing of the edge of the glass plate. This...
