Embodiment 1

[0020] An edge sealing method for vacuum glass, the steps are:

[0021] ⑴ Make the upper glass and the lower glass into two pieces of the same size, cut off a corner of the upper glass, and cut off a corner of the corresponding position of the lower glass corresponding to the upper glass to install the exhaust pipe;

[0022] ⑵ Arrange support on the lower glass, make an air extraction groove on the lower glass with one corner cut off, and put an air extraction pipe in the air extraction groove;

[0023] (3) Put glass powder paste around the edge of the lower glass, the glass powder paste should be placed within 20mm from the edge of the lower glass, and the powder distribution method can be automatically distributed with a glue gun or a powder distribution machine;

[0024] The glass frit paste is made of low-melting point glass frit and a binder with a mass ratio of 10:1, and the binder is a solvent-based binder such as cellulose or acetone.

[0025] (4) Put the combined upp...

Embodiment 2

[0028] The difference from Example 1 is that a semicircular through hole is made at any edge position corresponding to the upper glass and the lower glass after assembling, and an air extraction glass tube is installed radially of the semicircular through hole, or made on on a piece of glass.

[0029] Others are the same as in Example 1.

Abstract

The invention relates to an edge sealing method for vacuum glass, which comprises the steps of (1) manufacturing a piece of upper glass and a piece of lower glass which are same in size, and forming air exhaust slots for arranging an air exhaust pipe on the upper glass and the lower glass piece; (2) distributing a support on the upper glass, and placing the air exhaust pipe in the air exhaust slot; (3) placing glass powder slurry paste at the periphery of the edges of the lower glass, wherein the glass powder slurry paste is placed in a position which is away from the edges of the lower glass within 20mm; and (4) jointing the the upper glass and the lower glass, carrying out melting sealing in a furnace, and vacuumizing, so as to complete the manufacturing of the glass. The vacuum glass manufactured by using the method disclosed by the invention is in edging, namely, the upper glass and the lower glass are same in size, so that the edge sealing width can be effectively reduced, the actual area of the vacuum glass can be enlarged, and the appearance is attractive; the edge sealing can be carried out to the vacuum glass in the furnace, then the vacuumizing is carried out in open air, the convenience for butt joint of the air exhaust openings and opening sealing can be brought, the manufacture cost of the vacuum glass is greatly reduced, and the energy saving effect is good.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to an edge sealing method of vacuum glass. Background technique [0002] At present, the edge sealing of vacuum glass in the manufacturing process is to combine the upper and lower glass sheets, then fill the four-sided gap with low-melting glass powder, heat the edge sealing, and then vacuumize the sealing to complete the manufacture of vacuum glass. When performing edge sealing, the upper piece of glass and the lower piece of glass need to be made into large and small pieces respectively to form a side difference. Low glass powder is stacked on the side difference, and a siphon is formed when it is heated and melted in the furnace, so that the low melting point glass The powder enters into the four-sided gap to melt and seal, thus completing the edge sealing. This process method has the following disadvantages: 1. The form of large and small pieces results in a large width of the edge...
