Description

Technical Field

[0001] The present invention relates to the technical field of hollow glass manufacturing, and more specifically, to a manufacturing method of a novel thin multi-glass multi-cavity hollow glass. Background Art

[0002] Multi-glass multi-cavity insulating glass is a building material composed of multiple layers of glass and spacers in between. One or more hollow cavities are formed between each layer of glass. These cavities are usually filled with air or other gases to insulate, soundproof and improve energy efficiency. This design is widely used in building curtain walls, windows and other fields that require insulation and noise reduction. With the increasing requirements for energy saving and comfort in buildings, the use of multi-glass multi-cavity insulating glass has become a common choice because it can effectively reduce heat transfer while improving the energy efficiency of buildings.

[0003] However, the existing method for making multi-glass multi-cavity insulating glass usually adopts the method of alternating the lamination of glass and aluminum strips, and then uses structural adhesive to seal the gaps between the glass layers. As the number of hollow cavities increases, the thickness and weight of the glass also increase significantly. This not only causes the weight of the glass itself to increase, but also makes the construction and installation more complicated, requiring stronger support, increasing the difficulty of construction and labor costs. In addition, the increase in weight leads to an increase in the use of curtain wall aluminum profiles, thereby increasing the overall project cost. Therefore, although the prior art uses spacers and structural adhesives to maintain the hollow structure between the glasses, it still cannot effectively reduce the thickness and weight of the glass, and cannot reduce the difficulty and cost of installation, resulting in the multi-glass multi-cavity insulating glass system facing the problems of difficult construction, excessive weight and high cost. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a new type of thin multi-glass multi-cavity insulating glass manufacturing method, which uses glass hot-melt welding technology to implant ultra-thin glass in the middle of the insulating glass to create a cavity partition, which not only solves the problem of excessive glass thickness and weight in the prior art, but also reduces the difficulty of construction and installation. Through this innovative method, the thickness and weight of the glass are reduced, and the cost of the overall aluminum profile of the curtain wall is effectively reduced, thereby improving the overall economy and construction efficiency.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A novel method for manufacturing a thin multi-glass multi-cavity insulating glass comprises an outer glass (101), a middle glass (102), an air layer (103), a glass spacer (104) and a structural adhesive (105). Firstly, the glass spacer (104) is placed around the first outer glass (101), and the glass spacer (104) is welded to the first outer glass (101) by a hot-melt welding technique. This welding method can avoid the problem of easy aging of the conventional aluminum spacer when the butyl tape is used for bonding. The middle glass (102) is placed on the glass spacer (104), wherein the middle glass (102) is made of ultra-thin glass. The middle glass (102) is welded to the first outer glass (101) by a hot-melt welding technique. The glass spacers (104) are placed around the middle glass (102), and the middle glass (102) and the glass spacers (104) are welded together by a hot-melt welding technique. A second outer glass (101) is placed on the top, and the glass spacers (104) and the second outer glass (101) are welded together by a hot-melt welding technique, wherein an air layer (103) is formed between the first outer glass (101) and the second outer glass (101), and the gap between the first outer glass (101) and the second outer glass (101) is sealed with a structural adhesive (105).

[0007] As a further solution of the present invention, the method further comprises a glass hot-melt welding seam (106), wherein the air layer (103) formed between the first outer glass (101), the middle glass (102) and the second outer glass (101) is completely sealed by the glass hot-melt welding seam (106) and the structural adhesive (105); wherein the glass hot-melt welding seam (106) is located at the connection between the glass spacer (104) and the outer glass (101) and the middle glass (102), and the structure ensures the stability of the connection point; and the structural adhesive (105) is filled in the outer edges of the first outer glass (101) and the second outer glass (101) to form a sealing defense line.

[0008] As a further solution of the present invention, the glass hot-melt welding seam (106) is a permanent connection structure formed by hot-melting the glass spacer (104) and the outer glass (101) or the middle glass (102). The strength of this connection method is higher than that of traditional mechanical connection or adhesive connection. The glass hot-melt welding seam (106) ensures the air tightness of the air layer (103) and effectively prevents the generation of dew point and fog.

[0009] As a further solution of the present invention, the manufacturing method can manufacture insulating glass with multiple air layers (103) by increasing the number of layers of the middle glass (102) and the glass spacers (104). For each additional layer of the middle glass (102), two layers of the glass spacers (104) need to be added accordingly, and the glass hot-melt welding weld (106) is formed at each newly added connection.

[0010] As a further solution of the present invention, the structural adhesive (105) is filled in the outer edges of the first outer glass (101) and the second outer glass (101), and the structural adhesive (105) works together with the glass hot-melt welding weld (106) to ensure the sealing performance of the air layer (103) and prevent external air and moisture from entering the air layer (103).

[0011] The present invention uses glass hot-melt welding technology to implant ultra-thin glass into the middle of hollow glass to make a cavity partition, which reduces the thickness and weight of the glass, reduces the difficulty of construction and installation, and also reduces the cost of the overall aluminum profile of the curtain wall.

[0012] Compared with the prior art, the method for manufacturing a novel thin multi-glass multi-cavity insulating glass of the present invention has the following beneficial effects:

[0013] The present invention embeds ultra-thin glass into the middle of hollow glass to form a cavity interlayer through glass hot-melt welding technology, which significantly reduces the thickness and weight of the glass, reduces the difficulty of construction and installation, and effectively reduces the demand for curtain wall aluminum profiles, thereby reducing the overall project cost. Compared with the prior art, the traditional multi-glass multi-cavity hollow glass uses alternating layers of glass and aluminum strips and relies on structural adhesive for sealing. As the number of cavities increases, the thickness and weight of the glass gradually increase, resulting in increased difficulty in installation, increased required support force, and a significant increase in the use of curtain wall aluminum profiles, thereby pushing up construction costs and overall construction costs. Therefore, the present invention solves the problems of high cost and difficult construction in the prior art by reducing the weight of glass and improving construction efficiency.
