preparation example Construction

[0050] When the material of the support is low-temperature glass powder, the preparation method of the flat tempered vacuum glass further includes:

[0051] The first step is to cut two pieces of flat glass of the required size according to the shape and size of the flat tempered vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying;

[0052] The second step is to use stencil printing technology and low-temperature glass powder to prepare the edge banding frame and support on the welding surface of the treated glass, and ensure that the edge banding frame of the upper glass can be fitted in the upper glass after the upper and lower glass are aligned. Between the edge banding strips of the lower glass, after drying, it is tempered in a tempering furnace;

[0053] When the material of the support is low-temperature glass solder, the preparation method further includes:

[0054] The first step is to cut two pieces of flat glass of the required s...

Embodiment 1

[0128] Embodiment 1: see figure 1 , the two pieces of glass are tempered glass or semi-tempered glass, one of which is still low-emissivity glass, and there are edge-sealed frames on the two pieces of glass. The production method is as follows: First, cut the required size according to the shape and size of the vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass, after grinding, chamfering, cleaning and drying, use printing technology to print low-temperature glass powder paste on the two pieces of glass to form an edge banding frame, and the upper glass has an edge banding There are two edge sealing frames for the frame and the lower glass. The size of the upper glass edge sealing frame is between the lower glass edge sealing frames. After the upper and lower glass are combined, the upper glass edge sealing frame can be embedded in the lower glass Between the edge banding frames of the glass, the width of each edge banding frame is 1.5mm and...

Embodiment 2

[0131] Example 2: see figure 2 , the two pieces of glass of the vacuum glass are tempered glass or semi-tempered glass, one of which is still low-emissivity glass, and there are edge banding strips on the two pieces of glass. The production method is as follows: First, cut according to the shape and size of the vacuum glass to be produced A piece of flat glass and a piece of low-emissivity glass of the required size are edged, chamfered, cleaned and dried, and the low-temperature glass powder paste is printed on the two pieces of glass to form an edge banding frame by using template printing technology. There are two edge banding frames, the lower glass has three edge banding frames, the size of the upper glass edge banding frame is between the lower glass edge banding frames, after the upper and lower glass are combined, the upper glass edge banding frame can Fitted between the edge banding frames of the lower glass, each edge banding frame has a width of 1.5mm and a height ...

Abstract

The invention provides flat tempered vacuum glass. The glass comprises upper glass and lower glass, wherein the upper and lower glass are flat tempered glass; edge sealing strip frames are arranged on the peripheries of the welding surfaces of the upper and lower glass; the peripheries of the upper and lower glass are welded together through low-temperature solders which are low-melting-point metal or alloy solders; and a closed vacuum layer is formed between the upper glass and the lower glass and is internally provided with supports which are arranged in a lattice manner. A manufacturing method of the vacuum glass provided by the invention is simple in process; and the manufactured tempered vacuum glass can overcome the defects in the prior art and can be subjected to mass production.

Description

technical field [0001] The invention belongs to the field of vacuum glass manufacturing, in particular to a tempered vacuum glass and a manufacturing method thereof. Background technique [0002] At present, the general manufacturing method of vacuum glass is to first place tiny supports arranged in a lattice between two pieces of flat glass---the upper glass and the lower glass, and use the supports to prevent inward bending under the action of atmospheric pressure. Close them together, then weld the upper glass and the lower glass with low-melting glass solder with a melting temperature of about 450°C, and finally evacuate the closed space between the two glasses through the reserved air inlet , close the suction port to form a flat vacuum glass product. However, the above-mentioned process cannot be used to manufacture tempered vacuum glass from the original tempered glass. The first reason is that the tempered glass inevitably deforms during the tempering process, causi...
