Low-frequency single hollow sound-insulation composite glass

Abstract

The invention discloses low-frequency single hollow sound-insulation composite glass which comprises first glass and second glass; the first layer is the first glass, the second layer is a PVB sound-insulation film and the third layer is the second glass, wherein the first glass, the PVB sound-insulation film and the second glass are sequentially arranged from left to right; and the first glass ofthe first layer is bonded with the second glass of the third layer through the PVB sound-insulation film of the second layer. Therefore, the safety is enhanced, and the strict energy-saving standardis met; and meanwhile, the effect of isolating most of traffic low-frequency noise is achieved, and the configuration has high engineering universality.

Description

technical field [0001] The invention relates to a low-frequency single-hollow sound-insulating composite glass, which belongs to the technical field of building sound-insulating materials. Background technique [0002] With the continuous development of urbanization, residents living near airports, high-speed railways and expressways are often affected by day and night traffic noise, which is a low-frequency noise. To improve the quality of life of residents, this type of residential buildings needs Carry out professional sound insulation and noise reduction design, improve the sound insulation capacity of the overall outer enclosure structure, and reduce traffic noise from entering the daily indoor living environment. Compared with the walls, the external windows of the building envelope have poorer sound insulation performance, which is a weak point for the building to isolate traffic noise, while the insulating glass of ordinary external windows is very weak in isolating ...

AI Technical Summary

Problems solved by technology

However, the glass hollow cavity is filled with intermediate connecting columns, the hollow cavity is vacuumed, and the unconventional glass processing technology is complex and the production efficiency is low. At the same time, the indoor visual effect is not transparent after the window is installed, and the safety and durability are poor. , so the overall engineering versatility is poor

[0006] It can be seen from the background technology above that traffic noise is an important pain point in daily life for residents living in the above-mentioned areas. At present, there is a lack of systematic research on low-frequency sound insulation of doors and windows, and there are no mature products to solve this problem. At the same time, for Due to the extremely strict energy-saving regulations in the cold and cold regions of the north, it is difficult for the traditional single-hollow sound-insulating glass to meet the heat insulation requirements, so the improved single-hollow low-frequency sound-proof glass has important practical significance
