[0001] The utility model relates to the technical field of sound insulation panels, and more particularly to a sound insulation panel structure. Background Art

[0002] With the rapid development of social economy and the improvement of living standards, people's requirements for sound insulation in buildings are increasing. Firstly, noise has become a major public nuisance in modern life, which has a great impact on people's daily life, work, study and mental health, especially for children, the elderly, patients and heart patients. Secondly, people's demand for privacy in life has also increased, and they hope that their lives and living environments can be more private to ensure their own safety.

[0003] At present, in order to reduce noise interference and improve privacy, sound insulation panels are usually installed on the walls of houses. However, traditional sound insulation panels are simply stacked with a layer of sound insulation, and the sound insulation effect is average, which is difficult to meet higher sound insulation requirements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a sound insulation board structure with reasonable structural design and good sound insulation effect.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sound insulation board structure, comprising a substrate board, one side of the substrate board is compounded with a shock-absorbing layer, a sound insulation layer is compounded on the shock-absorbing layer, the sound insulation layer comprises an inner sound insulation layer, an aluminum foil layer and an outer sound insulation layer, the aluminum foil layer is arranged between the inner sound insulation layer and the outer sound insulation layer, and the inner sound insulation layer or the outer sound insulation layer has a concave-convex structure.

[0006] The utility model is further configured as follows: the inner side of the inner sound insulation layer is compounded with the shock absorbing layer, and the outer side is compounded with the aluminum foil layer; the inner side of the outer sound insulation layer is flat and compounded with the aluminum foil layer, and the outer side is configured as a concave-convex structure.

[0013] The utility model is further configured as follows: the shock absorbing layer is made of butyl rubber or nitrile rubber material

[0014] In summary, the present invention has the following beneficial effects:

[0015] Compared to the prior art, the present invention provides a sound insulation layer composed of an inner sound insulation layer, an aluminum foil layer, and an outer sound insulation layer. A concave-convex structure is provided on either the outer or inner sound insulation layer. This concave-convex structure increases the surface area of the material, allowing sound waves to be more efficiently reflected from the surface, thereby improving the sound absorption effect. The concave-convex structure also has a semicircular depression within it, which absorbs the energy of sound waves and attenuates them, thereby enhancing the sound insulation effect. Furthermore, the aluminum foil layer not only reflects sound waves, allowing them to be better absorbed within the sound insulation layer, but also increases the overall strength of the sound insulation layer, resulting in a relatively thicker sound insulation layer. Furthermore, the aluminum foil layer also improves the moisture resistance of the sound insulation layer to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] This embodiment discloses a sound insulation board structure, such as Figure 1-5 As shown, it includes a substrate plate 1, wherein the substrate plate 1 is the main body. Therefore, unless otherwise specified, the direction close to the substrate plate 1 is considered to be the inside, and the direction away from the substrate plate 1 is considered to be the outside. Furthermore, a shock-absorbing layer 2 is compounded on one side of the substrate plate 1, and a sound insulation layer 3 is compounded on the shock-absorbing layer 2. The sound insulation layer 3 includes an inner sound insulation layer 301, an aluminum foil layer 302, and an outer sound insulation layer 303. The aluminum foil layer 302 is arranged between the inner sound insulation layer 301 and the outer sound insulation layer 303. Through the above structure, the inner and outer double-layer sound insulation layers combined with the aluminum foil layer in the middle can increase the overall strength of the sound insulation layer, increase the thickness of the sound insulation layer to a certain extent, and improve the sound insulation effect. If a very thick sound insulation layer is simply provided, because the material of the sound insulation layer is generally flexible, it is easy to deform, and the strength of the plate is poor. However, the provision of an aluminum foil layer can stabilize the structure of the sound insulation layer in the middle to prevent it from deformation. And since the sound insulation layer is preferably made of rubber-plastic sound insulation cotton or melamine cotton or pearl cotton or polyethylene material, the moisture-proof effect of the inner and outer sound insulation layers themselves is general. If the wall is damp (for example, near the bathroom, etc.), the aluminum foil layer can also be set to isolate moisture, increase the moisture-proof performance of the overall sound insulation layer 3, and avoid moisture seepage affecting the substrate board 1.

[0024] Furthermore, based on the above, the present invention has a variety of layer structure embodiments, which are described below in detail in the following embodiments:

[0025] Example 1:

[0026] Reference Figure 2 The inner side of the inner sound insulation layer 301 is laminated with the shock absorbing layer 2, and the outer side is laminated with the aluminum foil layer 302. The inner side of the outer sound insulation layer 303 is flat and laminated with the aluminum foil layer 302, while the outer side is provided with the concave-convex structure 4. Furthermore, the substrate plate 1 is provided as an extruded board substrate, which includes an extruded board 5 located in the center, and a mortar layer 501 laminated on the extruded board 5. The mortar layer 501 is located on both sides of the extruded board 5. The structure of the first embodiment is to arrange the concave-convex structure 4 on the outside. Therefore, after being fixed to the wall, the concave-convex structure 4 can better block and isolate noise from outside the wall.

[0027] Example 2:

[0028] Reference Figure 3 In the second embodiment, the mortar layer 501 between the extruded board 5 and the shock absorbing layer 2 is removed based on the first embodiment. When the shock absorbing layer is made of a material with good viscosity such as nitrile rubber, it can be directly laminated to the extruded board 5. Therefore, the inner mortar layer 501 is not necessary and can be removed to make the structure of the board simpler.

[0029] Example 3:

[0030] Reference Figure 4 In the third embodiment, aluminum gusset plate 6 can be selected as the base material plate based on the first or second embodiment.

[0031] Example 4:

[0032] Reference Figure 5 Example 4 builds on Examples 1 to 3 by placing an aluminum foil layer 302 on the outer side of the outer sound insulation layer 303, while the inner side of the inner sound insulation layer 301 is provided with a concave-convex structure 4. When fixing to a wall that requires a flat surface, the original concave-convex structure should be placed on the inner side, while the aluminum foil layer 302 is placed on the outer side. This creates a flat outer surface and facilitates fixing. Furthermore, with the concave-convex structure 4 facing inward, unlike Examples 1 to 3, Example 4 significantly improves the ability to block noise from entering the room. Therefore, it can be adapted to various scenarios.

[0033] Preferably, in the above embodiment, the extruded plate is preferably a graphite extruded plate or an XPS extruded plate; the shock absorbing layer 2 is made of butyl rubber or nitrile rubber material, and the extruded plate can also be replaced by a polyurethane plate.

[0034] Further, refer to Figure 1 The concave-convex structure 4 includes a number of concave-convex ridges 401 arranged in an oblique and cross-arranged manner, and a number of semicircular recesses 402 distributed in an array are provided in the concave parts of the concave-convex ridges. Through the above structure, the concave-convex ridges 401 are arranged in a cross and oblique manner, which can obtain better structural strength. At the same time, when bonded to a vertical wall, the oblique concave-convex ridges 401 are arranged so that each concave-convex ridge 401 can provide a reaction force for supporting the vertical downward gravity, and the connection strength is also higher. In addition, the semicircular recesses 402 can allow sound waves to enter its interior, reflect the absorbed energy inside the recess, and attenuate the sound waves, thereby improving the sound insulation effect. In general, the concave-convex structure 4 increases the surface area of the material as a whole, so that sound waves will be emitted more on the surface of the material, etc., thereby improving the sound absorption effect.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
