Description

Technical Field

[0001] This utility model relates to the field of soundproof glass technology, and in particular to soundproof glass with a multi-layer composite soundproof layer. Background Technology

[0002] Glass, an amorphous inorganic non-metallic material, is typically made from a variety of inorganic minerals such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, and soda ash, with the addition of small amounts of auxiliary materials. Its main component is silicon dioxide and other oxides. It is an amorphous solid with an irregular structure and is widely used in buildings, primarily for wind insulation and light transmission; it is a mixture. In addition, there are colored glasses, which exhibit color due to the addition of certain metal oxides or salts, and tempered glass, which is produced through physical or chemical methods.

[0003] For residents living in busy urban areas or along roadsides, sound insulation is crucial for a good living, resting, and working environment. Glass, as an important component of modern curtain walls, plays a vital role in sound insulation. However, current technology generally uses ordinary glass or double-glazed glass, which does not provide ideal sound insulation and needs further improvement. Furthermore, the edges of existing glass are prone to shattering upon impact.

[0004] Therefore, it is necessary to provide a soundproof glass with a multi-layered composite sound insulation layer to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the problems of poor sound insulation effect and easy breakage of existing multi-layer composite sound insulation glass, this application provides multi-layer composite sound insulation glass.

[0006] The soundproof glass with a multi-layer composite sound insulation layer provided in this application adopts the following technical solution:

[0007] The soundproof glass with a multi-layer composite sound insulation layer includes a protective component, an outer tempered glass, a first sound insulation component, a supporting glass, a second sound insulation component, and an inner tempered glass. The outer tempered glass, the first sound insulation component, the supporting glass, the second sound insulation component, and the tempered glass are all disposed on the inner side of the protective component.

[0008] Both the first sound insulation component and the second sound insulation component include a sealant layer, a vacuum cavity, a sound-absorbing membrane, a sound-insulating membrane, and a heat-insulating membrane. The vacuum cavity is formed inside the sealant layer, and the sound-absorbing membrane, the sound-insulating membrane, and the heat-insulating membrane are all disposed on the inner side of the vacuum cavity.

[0009] Preferably, the first sound insulation component is disposed on one side of the outer tempered glass, and the supporting glass is disposed on one side of the first sound insulation component.

[0010] Preferably, the second sound insulation component is disposed on one side of the supporting glass, and the inner tempered glass is disposed on one side of the second sound insulation component.

[0011] Preferably, the sound-insulating film is disposed on one side of the heat-insulating film, and the sound-absorbing film is disposed on one side of the sound-insulating film.

[0012] By adopting the above technical solution, the sound insulation membrane is also made of transparent materials, such as polyurethane or polyethylene. It also has a microporous structure inside, but the pore size and porosity are different from those of the sound-absorbing membrane. The pore size is 30-80 micrometers. This material has a high density and good sound insulation and damping characteristics, which can effectively block the propagation of sound. When sound waves reach the sound insulation membrane, they are not only absorbed in the micropores, but the sound intensity is also further reduced due to the damping effect of the material itself.

[0013] Preferably, the protective component includes a protective frame and a protective pad, with the protective pad being fixedly installed on the inner side of the protective frame.

[0014] Preferably, the protective pad is wrapped around the outer tempered glass, the first sound insulation component, the supporting glass, the second sound insulation component, and the outer surface of the inner tempered glass.

[0015] By adopting the above technical solution, the other side of the supporting glass and the inner tempered glass are bonded to both sides of the second sound insulation component. The structure of the second sound insulation component is the same as that of the first sound insulation component. The vacuum cavity of the second sound insulation component is formed by the supporting glass and the inner tempered glass.

[0016] Preferably, the sound-absorbing membrane has a plurality of micropores distributed inside, and the sound-insulating membrane also has a plurality of micropores distributed inside, and both the sound-absorbing membrane and the sound-insulating membrane are made of transparent material.

[0017] By adopting the above technical solution, the sound-absorbing membrane is made of transparent polymer materials, such as polycarbonate or ethylene-vinyl acetate copolymer, which has good optical transparency and will not significantly affect the light transmission performance of glass. Its interior has a number of micropore structures with a pore size between 50-100 micrometers, which can resonate with sound waves of different frequencies. When sound propagates to the sound-absorbing membrane, the sound waves will enter the micropores and undergo friction and reflection in the pores, converting sound energy into heat energy, thereby achieving efficient sound absorption.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The multi-layer composite soundproof glass provided by this utility model, through the vacuum chamber in the first and second soundproof components, can significantly reduce the path of sound transmission through the air because there is no air inside; at the same time, with the synergistic effect of the sound-absorbing film and the sound-insulating film, the sound absorption and sound insulation effects can be further enhanced in actual use, reducing the sound intensity; in this way, the sound energy is continuously weakened during the propagation process as it passes through these layers of structures, thereby significantly enhancing the sound insulation effect of the glass;

[0020] With the protective frame and protective pads in the protective components, when the glass is hit, the two will bear the impact first; among them, the elasticity of the protective pads can absorb the energy generated by the impact, reduce the direct impact force on the glass, and thus protect the glass edges from breaking.

[0029] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0030] This application discloses soundproof glass with a multi-layered composite sound insulation layer. (Refer to...) Figure 1 The multi-layer composite soundproof glass includes: a protective component 1, an outer tempered glass 2, a first soundproof component 3, a supporting glass 4, a second soundproof component 5, and an inner tempered glass 6. The outer tempered glass 2, the first soundproof component 3, the supporting glass 4, the second soundproof component 5, and the tempered glass 6 are all located on the inner side of the protective component 1.

[0031] The first sound insulation component 3 and the second sound insulation component 5 both include a sealant layer 51, a vacuum cavity 52, a sound-absorbing membrane 53, a sound-insulating membrane 54, and a heat-insulating membrane 55. The vacuum cavity 52 is opened inside the sealant layer 51, and the sound-absorbing membrane 53, the sound-insulating membrane 54, and the heat-insulating membrane 55 are all disposed on the inner side of the vacuum cavity 52.

[0032] The first sound insulation component 3 is disposed on one side of the outer tempered glass 2, and the supporting glass 4 is disposed on one side of the first sound insulation component 3.

[0033] The second sound insulation component 5 is disposed on one side of the supporting glass 4, and the inner tempered glass 6 is disposed on one side of the second sound insulation component 5.

[0034] The supporting glass 4 and the outer tempered glass 2 are respectively bonded to both sides of the first sound insulation component 3. The vacuum cavity 52 on the first sound insulation component 3 is through-type. By blocking the supporting glass 4 and the tempered glass 2, the two sides of the vacuum cavity 52 are blocked, so that the vacuum cavity 52 is kept in a vacuum state.

[0035] The other side of the supporting glass 4 and the inner tempered glass 6 are bonded to both sides of the second sound insulation component 5. The structure of the second sound insulation component 5 is the same as that of the first sound insulation component 3. The vacuum cavity 52 of the second sound insulation component 5 is formed by the supporting glass 4 and the inner tempered glass 6.

[0036] The sound insulation membrane 54 is disposed on one side of the heat insulation membrane 55, and the sound absorption membrane 53 is disposed on one side of the sound insulation membrane 54.

[0037] The protective component 1 includes a protective frame 11 and a protective pad 12, with the protective pad 12 fixedly installed on the inner side of the protective frame 11.

[0038] Protective pads 12 are wrapped around the outer tempered glass 2, the first sound insulation component 3, the supporting glass 4, the second sound insulation component 5, and the inner tempered glass 6.

[0039] The sound-absorbing membrane 53 has several micropores distributed inside, and the sound-insulating membrane 54 also has several micropores distributed inside. Both the sound-absorbing membrane 53 and the sound-insulating membrane 54 are made of transparent material.

[0040] The sound-absorbing membrane 53 is made of transparent polymer materials, such as polycarbonate or ethylene-vinyl acetate copolymer, which has good optical transparency and will not significantly affect the light transmission performance of glass. Its interior is uniformly distributed with several micropore structures with a pore size between 50 and 100 micrometers, which can resonate with sound waves of different frequencies. When sound propagates to the sound-absorbing membrane 53, the sound waves will enter the micropores and undergo friction and reflection within the pores, converting sound energy into heat energy, thereby achieving efficient sound absorption.

[0041] The sound insulation membrane 54 is also made of transparent materials, such as polyurethane or polyethylene, and it also has a microporous structure inside. However, the pore size and porosity are different from those of the sound absorption membrane 53. The pore size is 30-80 micrometers. This material has a high density and good sound insulation and damping properties, which can effectively block the propagation of sound. When sound waves reach the sound insulation membrane 54, they will not only be absorbed in the micropores, but the sound intensity will also be further reduced due to the damping effect of the material itself.

[0042] The heat insulation film 55 is composed of a multi-layer composite structure. The base material is a polyester film, on which a metal oxide coating, such as indium tin oxide or titanium oxide, is deposited through processes such as magnetron sputtering or coating. This structural design enables it to effectively block infrared and ultraviolet rays, reducing the exchange of heat between indoors and outdoors. In hot weather, the heat insulation film 55 can prevent external heat from entering the room through the glass; in cold weather, it can prevent indoor heat loss, providing a good heat insulation effect. At the same time, the material has high light transmittance, so it does not affect indoor lighting while achieving its heat insulation function.

[0043] The working principle of the multi-layer composite soundproof glass provided by this utility model is as follows:

[0044] When sound travels to the soundproof glass, it first passes through the outer tempered glass 2, which provides initial sound blocking. Then, the sound enters the first soundproofing component 3, where the vacuum chamber 52, lacking air, prevents sound transmission, significantly reducing its propagation. Next, the sound encounters the sound-absorbing membrane 53, where micropores cause friction and reflection, converting sound energy into heat and absorbing sound. The sound then passes through the soundproofing membrane 54, where micropores further absorb sound energy, reducing its intensity. The supporting glass 4 supports and stabilizes the entire glass structure. The sound continues into the second soundproofing component 5, repeating the vacuum blocking, sound absorption, and soundproofing processes, further processing the sound. Finally, the sound reaches the inner tempered glass 6, which further blocks sound transmission, achieving excellent sound insulation.

[0045] When subjected to a collision, the protective frame 11 and the protective pad 12 in the protective component 1 will be impacted first. The protective pad 12 has a certain elasticity and can absorb the energy generated by the collision, reduce the direct impact of the impact force on the glass, and protect the glass edge from being easily broken. At the same time, the outer tempered glass 2 and the inner tempered glass 6 have high strength and can withstand a certain impact force, thus improving the overall impact resistance of the glass.

[0046] In addition, the presence of the heat insulation film 55 can reduce the exchange of heat between indoors and outdoors, preventing external heat from entering the room in hot weather and preventing indoor heat loss in cold weather, thus playing a role in energy saving and heat preservation.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
