Description

Technical Field

[0001] The present invention relates to the technical field of glass production, in particular to an offline double-silver Low-e laminated insulating glass and a processing technology thereof. Background Art

[0002] Insulating glass, invented by Americans in 1865, is a new building material offering excellent thermal and sound insulation, aesthetics, practicality, and reduced building weight. It utilizes two (or three) panes of glass bonded to an aluminum alloy frame containing a desiccant using a high-strength, airtight composite adhesive, resulting in highly effective sound and heat insulation. Insulating glass has gained worldwide recognition for its superior properties over conventional double-glazing. Insulating glass is a glass product that utilizes two or more panes of glass, evenly spaced apart by effective supports and sealed around the perimeter, creating a dry air space between the panes. Its primary materials are glass, warm-edge spacers, corner plugs, butyl rubber, polysulfide adhesive, and desiccant. The two or more panes are bonded and sealed with sealing strips and glass strips. Dry air is introduced into the space between the panes, and the frame is filled with desiccant to ensure the air between the panes remains dry. According to requirements, glass sheets with various properties can be selected, such as colorless transparent float glass, embossed glass, heat-absorbing glass, heat-reflecting glass, wired glass, tempered glass, etc. and frame (aluminum frame or glass strip, etc.), and made by gluing, welding or melting.

[0003] Although the current double-silver Low-e laminated insulating glass has good insulation, heat preservation and noise reduction effects, its impact resistance is poor due to its hollow design. It is not possible to add a buffering suction structure in the hollow interlayer and add an impact-resistant protective film to the glass surface to improve the impact resistance of the insulating glass. It is impossible to achieve the purpose of enabling the insulating glass to withstand large impacts while ensuring the insulation, heat preservation and noise reduction effects of the insulating glass itself. It cannot prevent external impacts on the insulating glass, resulting in glass shattering, which brings great inconvenience to people's use. Summary of the Invention
