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

[0096] The present invention also provides a method for preparing flat low-altitude glass with a low-altitude layer. When the material of the support is low-temperature glass frit, it includes:

[0097] The first step is to cut two pieces of flat glass of the required size according to the shape and size of the flat low-altitude glass to be produced, and perform edge grinding, chamfering, cleaning and drying;

[0098] The second step is to use stencil printing technology and low-temperature glass frit on the welding surface of the two processed glasses to prepare the edge seal frame and support, and ensure that the edge seal frame of the upper glass can be embedded after the upper and lower glass are aligned. Fit between the edge banding strips of the lower glass, and then after drying, carry out high-temperature sintering and solidification of the edge banding strips and supports in a high-temperature furnace;

[0099] In the third step, low-temperature solder is placed betwe...

Embodiment 1

[0121] Embodiment 1: see figure 1, the two pieces of glass are flat 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 a piece of flat glass of the required size according to the shape and size of the low-altitude glass to be produced. and a piece of low-emissivity glass, after grinding, chamfering, cleaning, and drying, the low-temperature glass powder paste is printed on the two pieces of glass to form an edge banding frame using stencil printing technology, and the upper glass has an edge banding frame, The lower glass has two edge banding frames, and the size of the upper glass edge banding frame is between the two edge banding frames of the lower glass. After the upper and lower glass are combined, the edge banding frame of the upper glass can fit Between the two edge banding frames of the glass, the width of each edge banding frame is 1.5mm and the height is 0.7mm...

Embodiment 2

[0123] Example 2: see figure 2 , the two pieces of glass are flat 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 a piece of flat glass of the required size according to the shape and size of the low-altitude glass to be produced. and a piece of low-emissivity glass, after grinding, chamfering, cleaning, and drying, the low-temperature glass powder paste is printed on the two pieces of glass by stencil printing technology to form an edge banding frame, and the upper glass has two edge banding frames 1. The lower glass has three edge banding frames, the size of the upper glass edge banding frame is between the lower glass edge banding frame, after the upper and lower glass are combined, the upper glass edge banding frame can be fitted into the Between the edge banding frames, the width of each edge banding frame is 1.5mm and the height is 0.8mm; secondly, the two pie...

Abstract

The invention provides flat low-altitude glass comprising upper glass and lower glass which are sheet glass, wherein edge sealing strip frames are arranged at the peripheries of the welding surface of the upper glass and the lower glass, the peripheries of the upper glass and the lower glass are welded together by low-temperature solders, a closed low-altitude layer is formed between the upper glass and the lower glass, and supports arranged in a dot matrix manner are arranged in the low-altitude layer. According to a manufacturing method of the low-altitude glass provided by the invention, the manufactured low-altitude glass can overcome the defects in the prior art, and can be produced in batch.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a 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...
