These problems not only increase the overall energy consumption of buildings but also seriously affect the comfort and health of living spaces.

[0004] Therefore, lightweight sound insulation and heat insulation integrated wall panels are particularly needed to solve the above problems. Utility Model Content

[0016] Example: Lightweight sound insulation and heat insulation integrated wall panel, such as Figures 1-2As shown, the wall panel includes a decorative surface layer 1, a polyester fiber sound-absorbing cotton layer 2, a ceramic fiber fireproof and heat-insulating layer 3, a polyurethane elastic buffer layer 4, a diatomaceous earth adsorption layer 5, a basalt fiber reinforcement layer 6, an aerogel insulation layer 7, a bamboo fiber reinforced lightweight cement substrate 8, a graphene-modified acrylic resin waterproof and breathable layer 9, a nano-titanium dioxide protective layer 10, and a flexible sealing and damping layer 11. The decorative surface layer 1 is located on the outermost layer of the entire lightweight sound insulation and heat-insulating integrated wall panel. It uses a variety of environmentally friendly and aesthetically pleasing materials such as wood-grain PVC film, metal finish, or polymer decorative panels, allowing for flexible selection based on the actual decoration style. This not only meets diverse decorative needs but also possesses excellent weather resistance and surface protection performance, effectively protecting the internal functional layer structure of the wall panel and extending its overall service life. The polyester... The fiber sound-absorbing cotton layer 2 is placed on the back of the decorative surface layer 1. It is made of polyester fiber through hot pressing and has the advantages of being environmentally friendly, flame-retardant, and having good sound absorption effect. It absorbs and attenuates sound, enhances sound insulation, and the polyester fiber sound-absorbing cotton layer 2 has a porous structure formed by interwoven polyester fibers, which is conducive to the absorption and attenuation of sound waves. The ceramic fiber fireproof and heat-insulating layer 3 is placed on the back of the polyester fiber sound-absorbing cotton layer 2, and a polyurethane elastic buffer layer 4 is placed on it. The ceramic fiber fireproof and heat-insulating layer 3 uses ceramic fiber as raw material. With its high temperature resistance and low thermal conductivity, it prevents heat transfer and flame spread, improves fire resistance, and blocks sound transmission. The polyurethane elastic buffer layer 4 is made of polyurethane material. It uses its good elasticity to buffer external impacts and reduce vibration transmission. The closed-cell structure assists in heat preservation and sound insulation. A diatomaceous earth adsorption layer 5 is placed on the back of the polyurethane elastic buffer layer 4. Utilizing the rich microporous structure and large specific surface area of ​​diatomaceous earth, it adsorbs odors and harmful gases in the air, regulates indoor humidity, and scatters and absorbs sound. A basalt fiber reinforcement layer 6 is placed on the back of the polyurethane elastic buffer layer 4, upon which an aerogel insulation layer 7 is placed. The basalt fiber reinforcement layer 6 is woven from basalt fibers, utilizing the high strength, high modulus, and high temperature resistance of basalt fibers to further enhance the structural strength of the wall panel and improve its resistance to deformation. The aerogel insulation layer 7 uses nano-sized silica aerogel, which, with its extremely low thermal conductivity, effectively blocks heat transfer, improving the thermal insulation effect of the wall panel. Its porous structure also helps absorb some sound. Multiple bamboo fibers reinforce lightweight water... The cement substrates 8 are neatly arranged and embedded inside the aerogel insulation layer 7, with their backs flush. The bamboo fiber reinforced lightweight cement substrate 8 is a composite material made of bamboo fiber and lightweight cement-based material. The bamboo fiber gives the panel high strength and toughness, while the lightweight cement-based material reduces the overall weight and provides basic structural support and fire resistance. The graphene-modified acrylic resin waterproof and breathable layer 9 is located on the back of the aerogel insulation layer 7 and forms a tight contact with the bamboo fiber reinforced lightweight cement substrate 8. The graphene-modified acrylic resin waterproof and breathable layer 9 is made of graphene-modified acrylic resin, which ensures excellent waterproof performance while allowing water vapor to pass through, preventing mold and corrosion caused by moisture accumulation inside the wall panel and maintaining a dry environment inside the wall panel.A nano-titanium dioxide protective layer 10 is applied to the back of the bamboo fiber reinforced lightweight cement substrate 8. Utilizing the photocatalytic properties of nano-titanium dioxide, the nano-titanium dioxide protective layer 10 decomposes harmful gases in the air, possesses self-cleaning capabilities, and provides surface protection for the wall panel, resisting minor external erosion. A flexible sealing damping layer 11 is located at the innermost layer of the entire lightweight sound insulation and heat-insulating integrated wall panel, applied to the rear surface of the nano-titanium dioxide protective layer 10. The flexible sealing damping layer 11 uses butyl rubber-based damping material to fill the gaps between the wall panel sides and the installation structure (such as keel, adjacent wall panels), blocking the airborne sound transmission path, buffering side vibration transmission, and absorbing the minor deformation stress caused by temperature and humidity changes in the wall panel, preventing side cracking and delamination.

[0017] When installing lightweight sound insulation and heat insulation integrated wall panels, the construction workers first clean and level the wall base, then position and lay out the lines according to the design drawings, align the flexible sealing damping layer 11 of the wall panel with the installation position, and use adhesive to fix the wall panel to the wall surface.

[0018] When using lightweight sound-insulating and heat-insulating integrated wall panels, the polyester fiber sound-absorbing cotton layer 2 absorbs sound wave energy through its porous structure, attenuating sound propagation and significantly enhancing the sound insulation and noise reduction performance of the wall; the ceramic fiber fireproof and heat-insulating layer 3, with its excellent high-temperature resistance and low thermal conductivity, prevents heat transfer and flame spread, improving overall fire safety, while also providing some obstruction to sound propagation; the polyurethane elastic buffer layer 4, utilizing its good elasticity and closed-cell structure, buffers external impacts while assisting in achieving heat insulation and sound insulation functions; the diatomaceous earth adsorption layer 5, with its rich microporous structure and large specific surface area, adsorbs odor molecules and harmful gases (such as formaldehyde, benzene compounds, etc.) in the air, regulates indoor humidity, and scatters and absorbs sound waves, further enhancing the sound insulation effect; the basalt fiber reinforcement layer 6, with its high strength and high modulus characteristics, enhances the overall structural strength of the wall panel and improves its resistance to deformation; the aerogel insulation layer 7... With its extremely low thermal conductivity, nano-sized silica aerogel effectively blocks heat transfer, significantly improving the thermal insulation performance of the wall. Its porous structure also provides sound absorption and noise reduction. The bamboo fiber-reinforced lightweight cement substrate 8 uses natural bamboo fiber as a reinforcing material, combined with a lightweight cement matrix, giving the wall panel good strength and toughness while reducing overall weight, providing basic support and fire protection. The graphene-modified acrylic resin waterproof and breathable layer 9 has excellent waterproof performance while allowing water vapor to pass through, effectively preventing mold and corrosion caused by internal moisture accumulation and maintaining a dry environment inside the wall panel. The nano-titanium dioxide protective layer 10 utilizes its photocatalytic properties to decompose harmful gases in the air, has a self-cleaning function, and provides surface protection against minor external erosion. The flexible sealing and damping layer 11 acts as a sealant, buffer, and shock absorber at wall joints, ensuring long-term stable operation of the wall panel.
