Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to a multi-layer sound-insulating and noise-reducing tempered glass. Background Technology

[0002] In the prior art, utility model patent with announcement number CN219387687U discloses a sound-insulating and noise-reducing tempered glass. The glass includes a tempered glass frame, with inner sound-insulating plate fixing blocks at the four corners of the frame, and outer fixed sound-insulating plates and inner sound-insulating plates respectively set on the front and rear sides of the inner end, with the tempered glass body placed in the glass placement groove between them;

[0003] While the aforementioned structure achieves sound insulation and noise reduction to some extent, its tempered glass body is composed of multiple layers, including a tempered glass layer, a vacuum layer, a sound insulation and noise reduction film layer, an ethylene-vinyl acetate copolymer layer, a polyvinyl chloride-vinyl acetate copolymer layer, a polyvinyl chloride acrylate layer, and a sapphire tempered glass layer, all bonded together with adhesive coatings. However, this combination of materials is not optimal. The performance of some materials fails to fully exert their synergistic effect. Although the vacuum layer can reduce sound propagation, the vacuum isolation plates at both ends may experience a decrease in sealing due to changes in external temperature and humidity over long-term use, thus weakening the sound insulation effect of the vacuum layer. Furthermore, the sound insulation and noise reduction film layer and the ethylene-vinyl acetate copolymer layer have limited absorption and blocking effects on noise of different frequencies, making it difficult to comprehensively and effectively cope with complex noise environments. For example, high-frequency car horn sounds and low-frequency engine roars contained in traffic noise cannot be well isolated by this glass. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing tempered glass is difficult to fully and effectively cope with complex noise environments. Therefore, we propose a multi-layer sound-insulating and noise-reducing tempered glass.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-layer sound-insulating and noise-reducing tempered glass, comprising a tempered glass frame, with fixing blocks at the four corners of the tempered glass frame, and an outer sound-insulating plate and an inner sound-insulating plate respectively disposed on the front and rear sides of the inner end of the tempered glass frame, forming a glass placement groove between the outer and inner sound-insulating plates, and a tempered glass body disposed in the glass placement groove; the tempered glass body comprises a first tempered glass layer, a vacuum layer, a second tempered glass layer, a damping sound-insulating layer, a sound-absorbing layer, and a third tempered glass layer arranged sequentially from the inside to the outside; the two ends of the vacuum layer are respectively sealed and connected to the first tempered glass layer and the second tempered glass layer.

[0006] Preferably, the vacuum layer has a square sealing frame at its edge, and the sealing frame is fixedly connected to the first tempered glass layer and the second tempered glass layer by heat fusion.

[0007] Preferably, the damping sound insulation layer is connected to the second tempered glass layer and the sound absorption layer by a hot-press bonding process.

[0008] Preferably, the surface of the sound-absorbing layer has a plurality of irregularly distributed sound-absorbing holes.

[0009] Preferably, both the outer and inner sound insulation panels are covered with a sound-absorbing material layer on the side facing the glass placement groove, and the material of the sound-absorbing material layer is the same as that of the sound-absorbing layer.

[0010] Preferably, the outer surface of the tempered glass frame is provided with an uneven textured structure, and the textured structure is filled with a sound-absorbing material.

[0011] Preferably, the surfaces of the first tempered glass layer, the second tempered glass layer, and the third tempered glass layer are all coated with an anti-reflective film.

[0012] Preferably, the vacuum layer is provided with a support structure.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the multi-layer sound-insulating and noise-reducing tempered glass has undergone a comprehensive upgrade in structure and materials. The outer frame enhances the stability of the outer and inner sound insulation panels by optimizing the design of the fixing blocks, thereby improving the overall structural reliability and reducing maintenance costs. The glass layer is coated with an anti-reflective film using magnetron sputtering coating technology, which improves optical performance and reduces glare.

[0015] The vacuum layer, with its heat-sealed frame and internal support structure, overcomes the shortcomings of existing technologies where sealing performance is easily affected by the environment, ensuring stable sound insulation performance. The damping sound insulation layer uses butyl rubber material to effectively suppress vibration and block low-frequency noise; the sound-absorbing layer uses melamine foam combined with laser-engraved irregular sound-absorbing holes, significantly improving the absorption capacity for noise across the entire frequency range.

[0016] The outer and inner sound insulation panels are equipped with additional sound-absorbing material layers, and the tempered glass frame surface is designed with a textured surface and filled with sound-absorbing cotton to further enhance the sound absorption effect. All components and materials work together to form a multi-layered sound insulation system. Compared to existing devices, this system successfully solves problems such as poor sealing and weak material synergy, demonstrating superior sound insulation and noise reduction performance in complex noise environments and meeting users' needs for high-quality soundproof glass.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figures 1 to 4 As shown, this utility model provides a multi-layer sound-insulating and noise-reducing tempered glass, including a tempered glass outer frame 1. Fixing blocks 102 are fixedly connected to the four corners of the tempered glass outer frame 1. The size and shape of the fixing blocks 102 must ensure that they can stably fix the outer sound insulation panel 201 and the inner sound insulation panel 2. The outer sound insulation panel 201 and the inner sound insulation panel 2 are respectively installed on the front and rear sides of the inner end of the tempered glass outer frame 1, so that a glass placement groove 101 for placing the tempered glass body 3 is formed between them.

[0025] Compared to existing devices, the design of the outer frame fixing block 102 in this invention places greater emphasis on installation stability. Its optimized structure ensures a more secure fixation between the outer sound insulation panel 201 and the inner sound insulation panel 2, preventing loosening that could affect the sound insulation effect over long-term use. This design improves the overall structural reliability, extends the lifespan of the glass products, and reduces subsequent maintenance costs.

[0026] The first tempered glass layer 301, the second tempered glass layer 304, and the third tempered glass layer 306 are each made of tempered glass that meets the corresponding strength and quality standards. After cleaning the surface, an anti-reflective film is coated onto the surface of each layer. The anti-reflective film is applied using a magnetron sputtering coating process. By controlling the sputtering parameters, the film layer is uniformly adhered to the surface of the tempered glass, effectively reducing light reflection and improving the light transmittance and visual effect of the glass.

[0027] This invention features a more advanced glass coating process. While the background art does not mention anti-reflective coatings on glass surfaces, this invention, through the application of an anti-reflective coating, not only improves the optical performance of the glass but also reduces glare caused by light reflection to a certain extent, providing users with a more comfortable visual experience. This is a significant advantage of this invention in glass surface treatment.

[0028] A vacuum layer 302 is constructed between the first tempered glass layer 301 and the second tempered glass layer 304. First, a square sealing frame 303 is installed at the edge of the vacuum layer 302. The sealing frame 303 is made of a high-temperature resistant, aging-resistant, and well-sealing material, such as a special silicone material. The sealing frame 303 is fixedly connected to the first tempered glass layer 301 and the second tempered glass layer 304 by heat fusion. During the heat fusion process, temperature and pressure parameters are strictly controlled to ensure a strong and sealed connection between the sealing frame 303 and the tempered glass layers, preventing outside air from entering the vacuum layer 302. To further enhance the stability of the vacuum layer 302, a support structure is set within the vacuum layer 302. The support structure uses tiny columnar metal supports, evenly distributed within the vacuum layer 302, which can support the two layers of tempered glass while minimizing the impact on the sound insulation effect of the vacuum layer 302.

[0029] In the background patent, the vacuum isolation plates at both ends of the vacuum layer 302 are susceptible to decreased sealing performance and weakened sound insulation due to long-term environmental factors. This invention, however, employs a heat-sealed frame 303 and an internal support structure, significantly improving the sealing and stability of the vacuum layer 302. Even under complex temperature and humidity variations, the vacuum layer 302 maintains a good vacuum state, continuously delivering excellent sound insulation performance. Compared to the background patent, this invention demonstrates significant improvements and advantages in the structural design of the vacuum layer 302.

[0030] The damping sound insulation layer 305 is made of butyl rubber, a material with good damping properties, and is connected to the second tempered glass layer 304 by a hot-pressing bonding process. During hot-pressing bonding, the temperature is controlled within a suitable range to ensure that the damping sound insulation layer 305 and the second tempered glass layer 304 are tightly bonded together to form a stable structure.

[0031] The sound insulation and noise reduction membrane layer in its material combination has limited absorption and blocking effects on noise of different frequencies. This invention uses butyl rubber damping material as the damping sound insulation layer 305, which can effectively suppress glass vibration and reduce secondary noise caused by vibration, especially showing good blocking effect on low-frequency noise. The hot-pressing bonding process also ensures the bonding strength between the damping sound insulation layer 305 and the glass layer, allowing each layer of material to better exert its synergistic effect and perform better in noise blocking.

[0032] Laser engraving technology is used to precisely process multiple irregularly distributed sound-absorbing holes on the surface of the sound-absorbing layer. The sound-absorbing layer is made of melamine foam, a porous foam material with excellent sound absorption properties. Its internal porous structure can effectively absorb noise of different frequencies. After the sound-absorbing layer is completed, it is connected to the damping sound insulation layer 305 through a hot-press bonding process.

[0033] The sound-absorbing layer of this invention uses melamine foam material and is laser-engraved with irregular sound-absorbing holes, which significantly increases the sound-absorbing surface area and enables more efficient absorption of noise of various frequencies, including high and low frequencies. Whether it's high-frequency car horn noise from traffic or low-frequency engine roar, it can be effectively absorbed, and its sound insulation effect in complex noise environments far surpasses that of the prior art patent.

[0034] The fabricated layers are assembled in sequence as follows: first tempered glass layer 301, vacuum layer 302, second tempered glass layer 304, damping and sound insulation layer 305, sound absorption layer and third tempered glass layer 306. Through hot pressing and other processes, the layers are tightly bonded to form a complete tempered glass body 3.

[0035] This layered structure fully utilizes the properties of each layer of material, achieving multi-layered noise blocking and absorption through a scientific and rational combination. Unlike the prior art patent where some materials failed to fully exert their synergistic effect, the materials in this invention work together to significantly improve the overall sound insulation and noise reduction performance.

[0036] On the side of the outer sound insulation panel 201 and the inner sound insulation panel 2 facing the glass placement groove 101, a sound-absorbing material layer is evenly covered. The material of the sound-absorbing material layer is the same as that of the sound-absorbing layer, which is melamine foam. By means of adhesive bonding or hot pressing, the sound-absorbing material layer is firmly attached to the outer sound insulation panel 201 and the inner sound insulation panel 2, further enhancing the noise absorption effect.

[0037] The background patent did not provide any special treatment for the side of the soundproof panel facing the glass placement groove 101. However, this utility model adds another layer of sound-absorbing barrier outside the glass body by covering it with a sound-absorbing material layer of the same material as the sound-absorbing layer. When noise propagates to the soundproof panel, this sound-absorbing material layer can absorb the noise first, reducing the noise intensity, thereby helping the glass body to better achieve sound insulation and noise reduction. This is another advantage of this utility model in the design of the soundproof panel.

[0038] On the outer surface of the tempered glass frame 1, an uneven textured structure is created using processes such as mold pressing. The shape and depth of the textured structure are optimized to increase the surface area and enhance the sound absorption effect. Sound-absorbing material, such as sound-absorbing cotton, is filled into the textured structure. During the filling process, it is ensured that the sound-absorbing material is evenly distributed within the textured structure, so that the tempered glass frame 1 also has a certain sound absorption capacity.

[0039] The background patent did not address the sound-absorbing design of the tempered glass frame 1. This invention innovatively sets a textured structure on the outer surface of the tempered glass frame 1 and fills it with sound-absorbing material. When noise propagates to the glass frame, the frame can initially absorb and reflect the noise, reducing the amount of noise entering the glass interior. This comprehensively improves the sound insulation and noise reduction performance of the glass product. Compared to the background patent, the structural design is more comprehensive and complete.

[0040] The prepared tempered glass body 3 is placed in the glass placement groove 101, and the outer sound insulation plate 201, the inner sound insulation plate 2 and the tempered glass body 3 are stably connected by the fixing block 102 and other structures to form a complete multi-layer sound insulation and noise reduction tempered glass product.

[0041] This invention relates to multi-layered sound-insulating and noise-reducing tempered glass, which features comprehensive optimization and improvement in material selection and structural design. Compared to the prior art patent, it employs more advanced technologies and more rational designs in all aspects, from the main glass structure to the outer frame and sound insulation panels, effectively solving problems such as poor sealing, insufficient material synergy, and weak adaptability to complex noise environments found in the prior art. This invention can more effectively absorb and block noise of different frequencies, exhibiting better sound insulation and noise reduction effects in complex noise environments, thus meeting users' needs for high-quality soundproof glass.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
