Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass, and specifically relates to a sound-insulating and noise-reducing tempered glass. Background Art

[0002] Among related technologies, sound insulation and noise reduction are gaining increasing attention in modern architecture and engineering, particularly in noisy urban environments, where people demand a higher level of quiet and comfort in their living and working spaces. While traditional sound insulation materials and methods can reduce noise to a certain extent, they often suffer from limited effectiveness, high material costs, complex installation, and aesthetic issues.

[0003] Tempered glass is a widely used material in construction and decoration. Its high strength, safety, and weather resistance make it an indispensable component of modern architecture. However, the sound insulation performance of ordinary tempered glass is not ideal and cannot meet the requirements of places with high sound insulation requirements.

[0004] To improve this situation, existing technologies attempt to enhance sound insulation by increasing the thickness of glass. However, this increases the weight of the glass, making installation and transportation more difficult and increasing costs. Furthermore, simply increasing the thickness cannot effectively block all frequencies of sound waves, so the sound insulation effect is still limited. Utility Model Content

[0005] The purpose of the present invention is to provide a sound-insulating and noise-reducing tempered glass to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a soundproof and noise-reducing tempered glass, the main component of which is a glass substrate. This glass substrate is unique in that it features a double-layered structure. To further enhance its soundproofing effect, at least one side of the glass substrate has been carefully designed to include a soundproofing layer. This soundproofing layer, typically made of a special soundproofing material, effectively absorbs and blocks the propagation of sound waves, significantly improving the glass's soundproofing performance. This design not only maintains high strength and safety, but also provides excellent soundproofing and noise reduction, enabling it to provide a quiet and comfortable space in any noisy environment.

[0007] This soundproofing layer is composed of a variety of carefully selected and combined soundproofing materials. Specifically, it includes a PVB layer and at least one soundproofing membrane. The PVB layer is a polyvinyl butyral material with excellent sound insulation and seismic resistance. The soundproofing membrane is carefully crafted from polyurethane, a material widely used in sound insulation for its excellent soundproofing properties. Polyurethane has excellent elasticity and flexibility, effectively absorbing and blocking noise of various frequencies, thereby providing excellent sound insulation. This combination not only improves the overall soundproofing effect, but also enhances the stability and durability of the structure. As a result, this soundproofing layer performs excellently in a variety of architectural and engineering applications, meeting the high sound insulation requirements of different occasions.

[0008] To ensure the stability and durability of the glass, an alloy frame is installed on the outer end of the glass substrate. This alloy frame is cleverly embedded in a fixing platform, thus providing a solid supporting structure for the entire soundproof tempered glass.

[0009] Further detailing the design of the sound insulation layer reveals an ingenious double-layer structure. A PVB layer is strategically placed between these two layers. This unique structural design not only significantly enhances sound insulation, making it difficult for sound to penetrate, thereby achieving even better sound insulation, but also improves overall stability and durability. This sandwich design allows the sound insulation layer to better withstand external pressure and impact, preventing damage or deformation from long-term use, thereby ensuring a longer lifespan and more stable performance.

[0010] At specific locations, sound insulation layers are strategically placed inside the double-layer tempered glass. This design effectively blocks and isolates the transmission path of outside noise. To further maximize sound insulation, the thickness of the insulation layer has been carefully designed, ranging from 2 to 10 mm. This thickness ensures adequate sound insulation while avoiding the added weight and cost associated with thicker materials. Furthermore, the thickness of the sound insulation film is precisely controlled between 0.1 and 1 mm, ensuring the desired sound insulation performance while avoiding the added weight and cost associated with thicker materials. Through this meticulous design, the entire sound insulation system achieves both high sound insulation performance and economical and practical performance.

[0011] Compared with the existing technology, the beneficial effects of the present invention are: by adding a sound insulation layer to the double-layer tempered glass, especially a sound insulation layer composed of a PVB layer and a polyurethane sound insulation film, the propagation of noise can be effectively reduced and the sound insulation effect indoors and outdoors can be improved; the use of double-layer tempered glass increases the strength and safety of the glass. Even if the glass breaks, the fragments will be adhered to the PVB layer, reducing the risk of injury.

[0012] Polyurethane material has good weather resistance and chemical resistance, which makes the sound insulation film not easy to age during long-term use and maintains the sound insulation effect; the thickness of the sound insulation layer is controlled between 2-10mm, so that the overall glass remains light and thin, easy to install and transport, and does not take up too much space.

[0013] By using an alloy frame, soundproof glass can be easily embedded in the fixing platform to adapt to different installation environments and needs; due to the improved sound insulation effect, it can provide users with a quieter living or working environment and reduce the interference of external noise.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-2 The utility model provides a technical solution: a sound-insulating and noise-reducing tempered glass, the main component of which includes a glass substrate 1. The uniqueness of this glass substrate 1 is that it is a tempered glass with a double-layer structure. In order to further enhance its sound insulation effect, at least one side of the glass substrate 1 has been carefully designed, and a sound insulation layer 2 has been added. This sound insulation layer 2 is usually made of a special sound insulation material that can effectively absorb and block the propagation of sound waves, thereby significantly improving the sound insulation performance of the glass. Through this design, the tempered glass not only maintains high strength and safety, but also has excellent sound insulation and noise reduction functions, enabling it to provide a quiet and comfortable space in various noisy environments.

[0019] This sound insulation layer 2 is composed of a variety of carefully selected and combined sound insulation materials. Specifically, it includes a PVB layer 2-1 and at least one sound insulation film 2-2. The PVB layer 2-1 is a polyvinyl butyral material with excellent sound insulation and shock resistance. The sound insulation film 2-2 is carefully made of polyurethane material, which is widely used in the sound insulation field due to its excellent sound insulation performance. Polyurethane material has excellent elasticity and flexibility, and can effectively absorb and block noise of various frequencies, thereby providing excellent sound insulation. This combination not only improves the overall sound insulation effect, but also enhances the stability and durability of the structure. Therefore, this sound insulation layer 2 performs well in various construction and engineering applications, and can meet the high sound insulation performance requirements of different occasions.

[0020] In order to ensure the stability and durability of the glass, an alloy outer frame 3 is also installed at the outer end of the glass substrate 1. This alloy outer frame 3 is cleverly embedded in a fixing platform 4, thereby providing a solid supporting structure for the entire soundproof tempered glass.

[0021] Further detailing the design of the sound insulation layer 2, we can see that it features a clever double-layer sound insulation membrane. A PVB layer 2-1 is strategically placed between these two layers. This unique structural design not only significantly enhances sound insulation, making it difficult for sound to penetrate, thereby achieving even better sound insulation, but also improves overall stability and durability. This sandwich design allows the sound insulation layer to better withstand external pressure and impact, preventing damage or deformation from long-term use, thereby ensuring a longer lifespan and more stable performance.

[0022] At specific locations, sound insulation layer 2 is cleverly positioned inside the double-layer tempered glass. This design more effectively blocks and isolates the propagation path of external noise. To further ensure maximum sound insulation, the thickness of sound insulation layer 2 has been carefully designed, ranging from 2 to 10 mm. This thickness ensures adequate sound insulation while avoiding the increased weight and cost associated with excessive thickness. Furthermore, the thickness of the sound insulation membrane 2-2 is precisely controlled between 0.1 and 1 mm, ensuring the desired sound insulation while avoiding the added weight and cost associated with excessive thickness. Through this meticulous design, the entire sound insulation system achieves both high sound insulation performance and economical and practical performance.

[0023] Through these careful designs and material selections, this sound-insulating and noise-reducing tempered glass not only has excellent sound insulation effects, but also has multiple advantages such as beauty, durability and safety, providing users with a more comfortable and peaceful living environment.

[0024] Working Principle: When working, the utility model uses two layers of glass substrate 1 to effectively block the transmission of sound. Tempered glass is stronger than ordinary glass and has better impact resistance. At the same time, when broken, it will break into small and blunt fragments, reducing the risk of injury.

[0025] A sound insulation layer is placed between the two layers of glass. This layer consists of a PVB layer 2-1 and at least one sound insulation film 2-2. The PVB polyvinyl butyral layer has a certain degree of viscoelasticity, which can absorb and block sound waves, reducing sound transmission. The sound insulation film 2-2 is made of polyurethane material, which has excellent sound insulation properties and can further absorb and isolate sound waves.

[0026] The polyurethane sound insulation membrane 2-2 is located on both sides of the PVB layer to provide additional sound insulation. The porous structure of the polyurethane material can absorb sounds of different frequencies, thereby reducing the noise level.

[0027] The alloy outer frame 3 not only provides additional structural support for the glass, but also prevents air and sound from transmitting through the gaps at the edge of the glass. The fixing platform 4 is used to fix the alloy outer frame 3 in the appropriate position, ensuring the stability and sealing of the entire soundproof glass system.

[0028] Placing the sound insulation layer inside the double-layer tempered glass can more effectively block sound. The thickness of the sound insulation layer 2 is 2-10mm, while the thickness of the sound insulation film 2-2 is 0.1-1mm. This thickness design can provide the best sound insulation effect for sounds of different frequencies.

[0029] In summary, this sound-insulating and noise-reducing tempered glass works together through a combination of double-layer glass structure, PVB layer, polyurethane sound-insulating film, alloy outer frame and fixing platform to reduce the transmission of sound, thereby achieving the purpose of sound insulation and noise reduction.
