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

[0080] The preparation of the convex glass is to put the flat glass into a mold, place it in a bending furnace, raise the temperature to the softening temperature of 550-750°C, and rely on the gravity of the glass to make the glass downward to form a convex surface.

[0081] When the upper glass and the lower glass are flat glass, there are supports arranged in a lattice in the lower layer formed between the upper glass and the lower glass.

[0082] The material of the support is low temperature glass, metal, ceramics, glass or plastic, preferably low temperature glass.

[0083] The support is preferably made of low-temperature glass powder or low-temperature glass solder by stencil printing technology, and the sintering temperature of the low-temperature glass solder is lower than that of low-temperature glass powder.

[0084] The smallest unit of the support may be a lattice arrangement of equilateral triangles, and the side length of the triangle is about 30-300mm, preferab...

Embodiment 1

[0103] 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 lower glass edge banding frames. After the upper and lower glass are combined, the upper glass edge banding frame can fit into the lower glass Between the side strips, the width of each side strip is 1.5mm and the height is 0.8mm; secondly, the two pieces of...

Embodiment 2

[0106] Example 2: see figure 2 , 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 low-altitude 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 The frame and the lower glass have two edge-seal frames, and the size of the upper glass edge-seal frame is between the two edge-seal frames of the lower glass. After the upper and lower glass are combined, the edge seal frame of the upper glass can be fitted Between the two edge-sealed frames of the lower glass; secondly, put the two pieces of glass into the mold, pla...

Abstract

The invention discloses an edge sealing method for low-altitude glass. The method is used for sealing the peripheries of the low-altitude glass by edge sealing strip frames and metal solders at a high temperature. The peripheries of upper and lower glass of the low-altitude glass are provided with the edge sealing strip frames, so that the edge sealing of the low-altitude glass is simpler and more convenient to implement, and a sealing effect of the upper and lower glass is ensured by the embedding combination of the upper and lower edge sealing strip frames. The method provided by the invention is simple in process, low in cost and high in production efficiency, can ensure reliable sealing connection and the good sealing effect, can be used for manufacturing low-altitude glass in mass by virtue of a one-step method, and can be used for manufacturing not only common low-altitude glass but also tempered low-altitude glass.

Description

technical field [0001] The invention relates to the processing and manufacturing of low-altitude glass, in particular to an edge-sealing method of low-altitude glass and its products. 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 ins...
