Problems solved by technology

Due to the organic sealant itself containing moisture, poor anti-aging performance, poor air tightness and other reasons, the insulating glass often fails, which seriously affects the service life of the insulating glass.
[0004] The air in the air layer of insulating glass is sealed between two pieces of glass. Due to the change of external temperature, the pressure of the air layer will change. When the external temperature is high, the pressure is greater than atmospheric pressure and the glass is convex. When the external temperature is low, the pressure is lower than atmospheric pressure. , The glass is concave, resulting in the so-called "breathing" phenomenon, which affects the normal service life of the insulating glass

preparation example Construction

[0055] When the material of the support is low-temperature glass powder, the preparation method of the flat tempered low-altitude glass further includes:

[0056] 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 low-altitude glass to be produced, and perform edge grinding, chamfering, cleaning and drying;

[0057] 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;

[0058] When the material of the support is low-temperature glass solder, the preparation method further includes:

[0059] The first step is to cut two pieces of flat glass of th...

Embodiment 1

[0136] Embodiment 1: Referring to Fig. 1, two pieces of glass are tempered glass or semi-tempered glass, one of which is also low-emissivity glass, and edge sealing strips are arranged on the two pieces of glass. Shape and size Cut a piece of flat glass and a piece of low-emissivity glass to the required size, grind and chamfer, after 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. Among them, the upper glass has one edge sealing frame, and the lower glass has two edge sealing frames. The size of the upper glass edge sealing frame is between the lower glass edge sealing frames. The frame can be fitted between the edge sealing frames of the lower glass, the width of each edge sealing frame is 1.5mm, and the height is 0.6mm; secondly, the two pieces of glass are sent to the tempering furnace respectively, and under the high temperature of the tempering furnace The lower edge sealin...

Embodiment 2

[0139] Example 2: see figure 2 , the two pieces of glass of the low-altitude 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 according to the shape and size of the low-altitude glass. 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 of 0...

Abstract

The present invention provides a flat tempered low altitude glass, which comprises an upper glass and a lower glass, wherein the upper glass and the lower glass are flat tempered glasses, the peripheries of the welding surface of the upper glass and the lower glass have edge sealing strip frames, the peripheries of the upper glass and the lower glass are integratedly welded through a low temperature welding material, the low temperature welding material is a low melting-point metal or an alloy melding material, a sealed low altitude layer is formed between the upper glass and the lower glass, and a supporting matter aligned in a point lattice manner is arranged inside the low altitude layer. According to the present invention, the process of the low altitude glass manufacturing method is simple, disadvantages in the prior art can be overcome with the manufactured tempered low altitude glass, and mass production can be achieved.

Description

technical field [0001] The invention belongs to the field of glass manufacturing, in particular to tempered low-altitude glass and a manufacturing method thereof. Background technique [0002] With the strengthening of environmental protection and energy saving awareness, insulating glass has been widely promoted and applied, effectively improving the thermal insulation and sound insulation performance of doors and windows. The distance between two pieces of flat glass of insulating glass, that is, the thickness of the air layer determines the effect of heat preservation and sound insulation. The thicker the air layer, the better the heat preservation and sound insulation effect, but increasing the thickness of the air layer will increase the thickness of the door and window frames. Therefore, it will increase the production cost of doors and windows; other methods, such as the use of coated glass, film sticking and filling inert gas in the middle of insulating glass, have c...
