preparation example Construction

[0039] When the material of the support is low-temperature glass powder, the preparation method of the flat tempered vacuum glass further includes:

[0040] 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;

[0041] 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;

Embodiment 1

[0093] Embodiment 1: see figure 1 , the two pieces of glass of the vacuum glass are flat tempered glass, one of which is still low-emissivity glass, and there are edge sealing strips 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 are ground, chamfered, cleaned and dried, and the low-temperature glass powder paste is printed on the two pieces of glass to form an edge strip frame by using template printing technology. Among them, the upper glass has two Edge banding frame and lower glass have 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 edge banding frame of the upper glass can fit in Between the edge banding frames of the lower glass, the width of each edge banding frame is 1.5mm and...

Embodiment 2

[0096] Example 2: 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 are ground, chamfered, cleaned and dried, and the low-temperature glass powder paste is printed on the two pieces of glass by printing technology to form an edge strip frame, of which the upper glass has two seals. There are three edge sealing frames for the side frame and the lower glass, and 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 fitted Between the two edge banding frames of the lower glass, the width of each edge banding frame...

Abstract

The invention provides flat tempered vacuum glass. The glass comprises upper glass and lower glass, which are flat tempered glass, wherein 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 glass 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 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...
