[0019] 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.

[0020] like Figure 1 As shown, this utility model provides a technical solution:

[0021] A user-friendly sound-absorbing cotton includes a surface layer 1, a fireproof layer 2 disposed on the lower end face of the surface layer 1, a moisture-proof layer 3 disposed on the lower end face of the fireproof layer 2, an intermediate layer 4 disposed on the lower end face of the moisture-proof layer 3, a sound-insulating reinforcement layer 5 disposed on the lower end face of the intermediate layer 4, and a bottom layer 6 disposed on the lower end face of the sound-insulating reinforcement layer 5. The surface layer 1 is made of polyester fiber with a thickness of 0.5–1 mm; the fireproof layer 2 is made of ceramic fiber with a thickness of 1–2 mm; and the moisture-proof layer 3 is made of polyethylene film with a thickness of 0.1–0.2 mm. mm; the intermediate layer 4 is made of polyester fiber or glass fiber and has a thickness of 3-5 mm; the sound insulation reinforcement layer 5 is made of thin aluminum plate and has a thickness of 2-3 mm; the bottom layer 6 is made of strong adhesive and has a thickness of 0.2-0.5 mm. A peelable thin plastic protective film 7 is also provided on the lower end surface of the bottom layer 6. The surface layer 1 and the fireproof layer 2, the fireproof layer 2 and the moisture-proof layer 3, the moisture-proof layer 3 and the intermediate layer 4, the intermediate layer 4 and the sound insulation reinforcement layer 5, and the sound insulation reinforcement layer 5 and the bottom layer 6 are all connected by physical bonding.

[0022] In this embodiment, the multi-layered structure design allows sound waves to be continuously reflected, scattered, and absorbed as they pass through each layer, weakening the sound waves from multiple angles. The different materials and thicknesses of the layers work together to effectively absorb and block sound waves of various frequencies, thus achieving good sound absorption and noise reduction effects over a wide frequency range. This is highly beneficial for places requiring noise reduction, such as recording studios, offices, and family bedrooms, providing a relatively quiet environment.

[0023] The presence of fire-resistant layer 2 gives the sound-absorbing cotton fire-resistant properties. In some public places, such as theaters and shopping malls, where people are densely populated, fire-resistant layer 2 can prevent the spread of fire and protect people and property in the event of a fire. For example, if this sound-absorbing cotton is used in the background music playing area of ​​a shopping mall, it will not become a combustion aid in the event of a fire; instead, it can, to some extent, prevent the spread of fire.

[0024] The moisture barrier layer 3 effectively prevents moisture from entering the sound-absorbing cotton. In humid environments, such as basements or areas in southern regions during the rainy season, the moisture barrier layer 3 prevents the sound-absorbing cotton from becoming damp and developing mold, thus ensuring its sound absorption performance and lifespan. For example, using this type of sound-absorbing cotton in a basement gym allows it to function normally even in high humidity environments.

[0025] The strong adhesive layer (6) and the peelable, thin plastic protective film (7) design make the installation of the sound-absorbing cotton extremely convenient. During installation, simply peel off the protective film and directly adhere the sound-absorbing cotton to the wall or other surface; no additional glue or complicated installation tools are required. This design is suitable for rapid installation in various locations, saving time and labor costs for both home and commercial renovations.

[0026] Working Principle: When sound waves first reach surface layer 1, the polyester fiber material of surface layer 1 causes the fibers to vibrate slightly. The dense structure of the polyester fibers allows some of the sound wave energy to be reflected and scattered on the fiber surface, while some energy is absorbed by the fibers and converted into heat or other forms of energy. This process initially weakens the intensity of the sound waves. The sound waves after passing through surface layer 1 enter fireproof layer 2. Although the ceramic fiber material of fireproof layer 2 primarily functions as fireproofing, it also has some influence on the sound waves. The relatively dense structure of ceramic fibers causes sound waves to be reflected and scattered again when propagating within them, further consuming the energy of the sound waves. The sound waves passing through fireproof layer 2 reach moisture-proof layer 3. Although the polyethylene film of moisture-proof layer 3 is very thin, its presence alters the medium characteristics for sound wave propagation. During the propagation of sound waves from ceramic fibers to polyethylene film, due to the difference in acoustic properties between the two materials, some energy is reflected and absorbed at the interface, further reducing the intensity of the sound waves. The intermediate layer 4 is the main sound-absorbing part. Its mixture of polyester fibers or glass fibers forms a loose structure. After sound waves enter the intermediate layer 4, they are continuously reflected and refracted within the loose fibrous structure. The interaction between the fibers and the sound waves causes the energy of the sound waves to be continuously absorbed and converted. During this process, due to the mixed structure and relatively large thickness of the fibers, a large amount of sound wave energy can be effectively absorbed. The remaining sound waves after absorption by the intermediate layer 4 reach the sound insulation reinforcement layer 5. According to the law of mass, the heavier aluminum plate material of the sound insulation reinforcement layer 5 has a better sound wave blocking effect. Sound waves are reflected on the surface of the aluminum plate, and the internal structure of the aluminum plate also absorbs some sound wave energy, further hindering the propagation of the sound waves. Finally, the sound waves reaching the bottom layer 6 have been greatly weakened. Although the strong adhesive and the peelable thin plastic protective film 7 of the bottom layer 6 are not the main sound-absorbing structures, they also have a certain blocking and absorption effect on weak sound waves.
