Description

Technical Field

[0001] This utility model relates to a novel soundproof insulated glass. Background Technology

[0002] Insulating glass, as a core component for building energy conservation and noise reduction, is usually composed of two glass substrates and a sealed cavity in the middle, relying on an air layer or inert gas to block the transmission of sound waves. The existing technology has significant drawbacks: First, temperature-induced deformation can easily cause the sealant to crack, leading to gas leakage and a sharp drop in sound insulation performance; second, traditional single-layer sound insulation materials (such as ordinary PVB film) are difficult to cover broadband noise, and the insulation effect of low-frequency traffic noise (below 125Hz) is less than 30dB; third, the protective structure is mostly rigid and fixed, which cannot alleviate stress accumulation under extreme temperatures and accelerate component aging. Utility Model Content

[0003] The purpose of this invention is to provide a novel soundproof insulated glass to solve the aforementioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A novel soundproof insulated glass includes protective nests, a sealing compound, a slot, glass substrate A, glass substrate B, and a composite sound insulation layer. The two sets of protective nests are fixedly connected by the sealing compound. The slot is formed inside the sealing compound. Glass substrate A and glass substrate B are glued together inside the slot. The composite sound insulation layer is distributed between glass substrate A and glass substrate B.

[0005] Based on the above technical solution, the protective nest includes an alloy shell, an argon-filled cavity, a phase change gel, and a pressure relief groove. The argon-filled cavity is provided on the inner side of the alloy shell, the phase change gel is distributed in the center of the argon-filled cavity, and the pressure relief groove is provided on the surface of the alloy shell.

[0006] Based on the above technical solution, the composite sound insulation layer includes silica aerogel, PET microperforated sound-absorbing membrane, PVB-nano rubber damping membrane, and poly(N-isopropylacrylamide) hydrogel. The PET microperforated sound-absorbing membrane is distributed inside the silica aerogel, the PVB-nano rubber damping membrane is distributed inside the PET microperforated sound-absorbing membrane, and the poly(N-isopropylacrylamide) hydrogel is distributed inside the PVB-nano rubber damping membrane.

[0007] Compared with the prior art, this utility model has the following advantages: This utility model achieves a breakthrough advantage through gradient material composite and dynamic stress release mechanism: On the one hand, the four-layer composite sound insulation layer forms a sound wave attenuation sequence: silica aerogel blocks mid-to-high frequency sound waves, PET microperforated membrane absorbs high frequency energy, PVB-nano rubber damping membrane scatters low frequency vibrations, and poly(N-isopropylacrylamide) hydrogel fills the micro gaps with temperature phase change, effectively improving the sound insulation of the entire frequency band; On the other hand, the argon gas filling cavity in the protective nest buffers pressure fluctuations, completely solving the industry problem of cracking of sealing colloid due to deformation.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-3 As shown, a novel soundproof insulated glass includes a protective nest 1, a sealing compound 2, a slot 3, a glass substrate A4, a glass substrate B5, and a composite sound insulation layer 6. The sealing compound 2 is fixedly connected between two sets of the protective nest 1. The slot 3 is formed inside the sealing compound 2. The glass substrate A4 and the glass substrate B5 are glued together inside the slot 3. The composite sound insulation layer 6 is distributed between the glass substrate A4 and the glass substrate B5.

[0014] The protective nest 1 includes an alloy shell 7, an argon gas filling cavity 8, a phase change gel 9, and a pressure relief groove 10. The argon gas filling cavity 8 is provided on the inner side of the alloy shell 7. The phase change gel 9 is distributed in the center of the argon gas filling cavity 8. The pressure relief groove 10 is provided on the surface of the alloy shell 7.

[0015] The composite sound insulation layer 6 includes silica aerogel 11, PET microperforated sound-absorbing membrane 12, PVB-nano rubber damping membrane 13, and poly(N-isopropylacrylamide) hydrogel 14. The PET microperforated sound-absorbing membrane 12 is distributed inside the silica aerogel 11, the PVB-nano rubber damping membrane 13 is distributed inside the PET microperforated sound-absorbing membrane 12, and the poly(N-isopropylacrylamide) hydrogel 14 is distributed inside the PVB-nano rubber damping membrane 13.

[0016] The working principle of this utility model is as follows: When the sound wave energy is transmitted, the high-frequency noise is first reflected by the glass substrate A / B (4 / 5); after the residual sound wave enters the composite sound insulation layer (6), the mid-frequency energy is dissipated by the nanopores of the silica aerogel (11), the high-frequency components are absorbed by the micropores of the PET microperforated membrane (12), and the low-frequency vibration is scattered by the silicon carbide particles of the PVB-nano rubber damping membrane (13). Finally, the sound bridge gap is sealed by the poly-N-isopropylacrylamide hydrogel (14) in the high-temperature liquefaction state; at the same time, when the ambient temperature rises, the volume of the argon gas filling cavity (8) of the protective nest (1) expands adaptively to avoid the sealing colloid (2) from bearing excessive stress and maintain the overall airtightness of the structure.

[0017] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
