Description

Technical Field

[0001] This utility model relates to the field of tempered glass technology, specifically to a type of tempered glass with hollow sound insulation. Background Technology

[0002] In recent years, with the acceleration of urbanization and industrial development, noise pollution has become increasingly serious. Noise generated by urban traffic, industrial equipment, and construction not only greatly interferes with people's quality of life but also has significant negative impacts on physical and mental health. Insulating glass, as an important component of modern building materials, is widely used in high-rise residential buildings, office buildings, airports, high-speed railway platforms, and other places with high sound insulation requirements due to its excellent sound insulation performance and energy-saving effect. Traditional insulated glass typically uses a cavity between two or more panes of glass. However, facing increasingly complex noise environments, traditional insulated glass still has certain limitations in terms of its ability to isolate low-frequency noise, the versatility of its sound insulation effect, and its structural strength. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass with hollow sound insulation, comprising a frame, wherein an outer glass, a middle glass, and an inner glass are sequentially installed from the outside to the inside of the frame, a cavity one is provided between the outer glass and the middle glass, a cavity two is provided between the middle glass and the inner glass, an argon gas layer is provided in the cavity one, a sulfur hexafluoride gas layer is provided in the cavity two, a PVB interlayer is provided on the inner side of the outer glass, a nano-aerogel interlayer is provided on one side of the PVB interlayer, and a micro Helmholtz resonator layer is provided on one side of the middle glass.

[0009] Compared with the prior art, this utility model provides a tempered glass with hollow sound insulation, which has the following beneficial effects:

[0010] This type of tempered glass with hollow sound insulation features two cavities, one and two, separated by an acoustic barrier layer. Argon and sulfur hexafluoride are introduced into cavities one and two, respectively, based on their density difference and excellent acoustic impedance characteristics, improving heat insulation performance, attenuation of mid-to-high frequency noise, and blocking ability of low-frequency noise.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] Please see Figure 1-3In this embodiment: a tempered glass with hollow sound insulation includes a frame 1, and an outer glass 2, a middle glass 3 and an inner glass 4 are installed in the frame 1 from the outside to the inside. A cavity 1 5 is provided between the outer glass 2 and the middle glass 3, and a cavity 2 6 is provided between the middle glass 3 and the inner glass 4. An argon gas layer 7 is provided in the cavity 1 5, and a sulfur hexafluoride gas layer 8 is provided in the cavity 2 6. A PVB interlayer 9 is provided on the inner side of the outer glass 2, a nano aerogel interlayer 10 is provided on one side of the PVB interlayer 9, and a micro Helmholtz resonator layer 13 is provided on one side of the middle glass 3.

[0018] In this embodiment, by setting up cavity one 5 and cavity two 6, each cavity is separated by an acoustic barrier layer, and the cavity thicknesses of cavity one 5 and cavity two 6 are different to avoid resonance amplification at specific frequencies. By introducing argon and sulfur hexafluoride into cavity one 5 and cavity two 6, argon, with its high acoustic impedance, weakens the propagation of mid-to-high frequency sound waves; sulfur hexafluoride, due to its large molecular weight and high density, has an excellent isolation effect on low-frequency sound waves. The combination of the two gases enhances the soundproof glass's ability to block noise at different frequencies. A PVB interlayer 9 is provided on the inner side of the outer glass 2, which provides impact resistance. The structure has a buffering effect on sound and structural noise propagation. A nano-aerogel layer 10 is added to the other side of the PVB interlayer 9. The low thermal conductivity and high damping characteristics of the nano-aerogel material effectively absorb and scatter the sound waves entering the glass structure, further reducing the propagation of noise. A micro Helmholtz resonator layer 13 is set on one side of the middle glass 3. It selectively absorbs noise in specific frequency bands through the principle of resonance, especially showing a significant attenuation effect on low-frequency noise. The high efficiency of the micro-structure makes the overall sound insulation capability of the glass more targeted, which can solve the shortcomings of traditional insulated glass in low-frequency noise treatment.

[0019] Furthermore, a thin film metal mesh layer 11 is provided on one side of the nano-aerogel interlayer 10; a micro-perforated plate layer 12 is provided on one side of the thin film metal mesh layer 11.

[0020] Among them, a thin film metal mesh layer 11 is superimposed on one side of the nano aerogel interlayer 10. The high reflectivity of the metal material is used to reflect and scatter sound waves, which further enhances the sound insulation performance. A micro-perforated plate layer 12 is added to the other side of the thin film metal mesh 11. The acoustic characteristics of the perforated plate are used to increase the multiple transmission and reflection paths of sound waves, thereby significantly improving the noise attenuation effect.

[0021] Furthermore, an installation groove 14 is provided on the inner side of the frame 1, and the outer glass 2, middle glass 3 and inner glass 4 are respectively installed on the inner wall of the installation groove 14; sealing gaskets 15 are fixedly connected to the adjacent inner surfaces of the installation groove 14, and the sealing gaskets 15 are respectively attached to the outer glass 2, middle glass 3 and inner glass 4.

[0022] The inner side of the frame 1 is designed with a mounting groove 14, which firmly fixes the two sides of the triple-glazed glass to the inner wall of the mounting groove 14. A sealing gasket 15 is set inside the mounting groove 14. The sealing gasket 15 fits tightly against the side of the glass, preventing the possibility of noise from spreading through the gaps at the edge of the glass. At the same time, it enhances the sealing and impact resistance of the overall structure and ensures the stability of sound insulation performance during long-term use.

[0023] The working principle and usage process of this utility model are as follows: By setting up cavity one 5 and cavity two 6, each cavity is separated by an acoustic barrier layer. Furthermore, the cavity thicknesses of cavity one 5 and cavity two 6 are different to avoid resonance amplification at specific frequencies. Argon and sulfur hexafluoride are introduced into cavity one 5 and cavity two 6. Argon, due to its high acoustic impedance, weakens the propagation of mid-to-high frequency sound waves; sulfur hexafluoride, due to its large molecular weight and high density, has excellent isolation effect on low-frequency sound waves. The combination of these two gases enhances the soundproof glass's ability to block noise at different frequencies. A PVB interlayer 9 is set on the inner side of the outer glass 2. This layer has a buffering effect on impact sound and structurally propagated noise. A nano-aerogel layer 10 is added to the other side of the PVB interlayer 9, utilizing the low thermal conductivity and high impedance of the nano-aerogel material. The nano-aerogel interlayer 10 effectively absorbs and scatters sound waves entering the glass structure, further reducing noise propagation. A thin-film metal mesh layer 11 is superimposed on one side of the nano-aerogel interlayer 10. The high reflectivity of the metal material reflects and scatters sound waves, further enhancing the sound insulation performance. A micro-perforated plate layer 12 is added to the other side of the thin-film metal mesh 11. The acoustic properties of the perforated plate increase the multiple transmission and reflection paths of sound waves, thereby significantly improving the noise attenuation effect. A micro-Helmholtz resonator layer 13 is set on one side of the middle glass 3. It selectively absorbs noise in specific frequency bands through the resonance principle, especially showing a significant attenuation effect for low-frequency noise. The high efficiency of the micro-structure makes the overall sound insulation capability of the glass more targeted, which can solve the shortcomings of traditional insulated glass in low-frequency noise treatment.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
