Description

Technical Field

[0001] This utility model relates to the field of decoration materials technology, specifically to a high-performance sound-insulating and damping decorative panel. Background Technology

[0002] Decorative panels occupy an extremely important position in construction projects. Their development speed, variety, quality, style, and matching level all determine the level of building decoration. With social development and technological advancements, the traditional decorative panel industry is constantly innovating, endowing decorative panels with a wide range of new functions.

[0003] Existing honeycomb decorative panels typically only utilize the internal honeycomb core for sound insulation. However, due to the presence of air within the honeycomb structure, their sound insulation effect is poor under high noise levels. Furthermore, the single honeycomb composite structure does not possess good seismic damping performance. Therefore, we propose a high-performance sound-insulating and damping decorative panel. Utility Model Content

[0004] This application provides a high-performance sound-insulating and damping decorative panel to at least solve the problems of existing honeycomb decorative panels having poor sound insulation performance when encountering high noise levels, and the single honeycomb composite structure not having good seismic damping performance.

[0005] In a first aspect, this application provides a high-performance sound-insulating and damping decorative panel, comprising an inner core layer and two fiber skin layers located on both sides of the inner core layer, wherein the inner core layer comprises a honeycomb core layer and a sound-insulating and damping layer;

[0006] A hot melt adhesive film layer is provided between the honeycomb core layer and the sound insulation damping layer, between the honeycomb core layer and the fiber skin layer, and between the sound insulation damping layer and the fiber skin layer.

[0007] Optionally, the honeycomb core layer is made of any one of aramid paper honeycomb, quartz fiber cloth honeycomb, or microwave absorbing honeycomb, with a honeycomb aperture of 7-28 mm and a honeycomb shape of any one of polygons.

[0009] Optionally, the material of the fiber skin layer is either glass fiber or carbon fiber prepreg.

[0010] Optionally, a decorative overlay layer is also provided on the outer side of the two skin layers.

[0011] Compared with related technologies, the high-performance sound-insulating and damping decorative panel provided in this application has at least the following technical effects:

[0012] Structurally, it is designed as a multi-layer sandwich structure of "fiber skin layer + hot melt adhesive film layer + honeycomb core layer + hot melt adhesive film layer + sound insulation and damping layer + hot melt adhesive film layer + fiber skin layer", forming a high-performance composite board with integrated sound insulation and damping functions. The sound insulation and damping performance is enhanced by laying sound insulation felt, and decorative films can be laid according to different application scenarios. At the same time, the hot melt adhesive film layer can be layered and laid at room temperature in a sheet-like structure, and then melted and bonded under high temperature hot pressing. The production process is highly operable, the process is optimized and upgraded, and the finished product has the advantages of being lightweight and high-strength.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In related technologies, existing honeycomb decorative panels typically only use the internal honeycomb core for sound insulation. Since there is air inside the honeycomb, the sound insulation effect is poor when encountering loud noise. Furthermore, the single honeycomb composite structure does not have good seismic damping performance.

[0022] Based on the above, this utility model provides a high-performance sound-insulating and damping decorative panel, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0023] Example 1

[0024] This utility model embodiment provides a high-performance sound-insulating and damping decorative panel. Figure 1 This is a three-dimensional structural diagram of a high-performance sound-insulating and damping decorative panel according to an exemplary embodiment. Figure 2 This is an exploded cross-sectional view of a high-performance sound-damping decorative panel according to an exemplary embodiment. Figure 1-2 As shown, the high-performance sound-insulating and damping decorative panel includes an inner core layer and two fiber skin layers 40 located on both sides of the inner core layer. The inner core layer includes a honeycomb core layer 10 and a sound-insulating and damping layer 30.

[0025] A hot melt adhesive film layer 20 is provided between the honeycomb core layer 10 and the sound insulation damping layer 30, between the honeycomb core layer 10 and the fiber skin layer 40, and between the sound insulation damping layer 30 and the fiber skin layer 40.

[0026] In this embodiment, refer to the appendix. Figure 1-2 The honeycomb core layer 10 is made of any one of aramid paper honeycomb, quartz fiber cloth honeycomb, or wave-absorbing honeycomb, with a honeycomb pore diameter of 7-28 mm and a honeycomb pore shape of any one of polygons. The sound insulation damping layer 30 is a sound insulation felt. The fiber skin layer 40 is made of any one of glass fiber or carbon fiber prepreg.

[0027] In the above embodiment, the mechanical properties are controlled by adjusting the material, pore size and honeycomb shape of the honeycomb core layer 10. Different functionalities are achieved by selecting the material of the hot melt adhesive film layer 20 and the fiber skin layer 40. Furthermore, the sound insulation capability is further enhanced by the sound insulation damping layer 30 (sound insulation felt) and it has anti-vibration damping function. Compared with the existing products that fill the honeycomb core with sound insulation material, the use of quartz fiber cloth honeycomb and wave-absorbing honeycomb can increase wave absorption, high dielectric properties, ablation resistance, mechanical properties, etc., and expand the application scenarios.

[0028] See attached document Figure 1-2 The manufacturing process of this high-performance sound-insulating and damping decorative panel is as follows:

[0029] S1. Raw material composite production: Cut the raw materials to the corresponding size, and then lay them on the operating platform in the following order: fiber skin layer 40 + hot melt adhesive film layer 20 + honeycomb core layer 10 + hot melt adhesive film layer 20 + sound insulation damping layer 30 + hot melt adhesive film layer 20 + fiber skin layer 40.

[0030] S2. Place the laid semi-finished product into a hot press for hot pressing and shaping. Set the hot press temperature to 100-120℃, the heating rate to 2-5℃ / min, and hold for 70-80min. The hot melt adhesive film layer 20 melts under these process parameters, fully bonding the upper and lower surfaces of each layer of the decorative panel.

[0031] S3. After hot pressing is completed, turn off the hot press and wait for the temperature to cool down before taking out the finished high-performance sound insulation and damping decorative panel.

[0032] In summary, the high-performance sound-insulating and damping decorative panel provided by this utility model is structurally designed as a multi-layer sandwich structure of "fiber skin layer 40 + hot melt adhesive film layer 20 + honeycomb core layer 10 + hot melt adhesive film layer 20 + sound-insulating and damping layer 30 + hot melt adhesive film layer 20 + fiber skin layer 40", forming a high-performance composite panel with integrated sound-insulating and damping functions. The sound insulation capability is further enhanced by laying sound insulation felt, and it also has anti-vibration and damping functions. In addition, the hot melt adhesive film layer 20 is a sheet structure that is laid at room temperature and melted and bonded under high temperature and hot pressing. The production process is highly operable, the process is optimized and upgraded, and the finished product has the advantages of being lightweight and high-strength.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that, further, a decorative covering layer is provided on the outer side of the two skin layers 40.

[0035] Furthermore, following step S3, the process also includes:

[0036] S4. After hot pressing, decorative films are applied to the finished product according to different application scenarios to enhance the decorative effect of the composite board.

[0037] Other undescribed structures are described in Example 1.

[0038] In summary, the high-performance sound-insulating and damping decorative panel provided by this utility model embodiment is structurally designed as a multi-layer sandwich structure of "fiber skin layer 40 + hot melt adhesive film layer 20 + honeycomb core layer 10 + hot melt adhesive film layer 20 + sound-insulating and damping layer 30 + hot melt adhesive film layer 20 + fiber skin layer 40", forming a high-performance composite panel with integrated sound-insulating and damping functions. The sound insulation capability is further enhanced by laying sound-insulating felt, and it also has anti-vibration and damping functions. Furthermore, decorative films can be laid according to different application scenarios. Simultaneously, the production process, which combines the sheet-like structure of the hot melt adhesive film layer 20 at room temperature with melting and bonding under high-temperature hot pressing, is highly operable, with optimized and upgraded processes, and the produced finished product has the advantages of being lightweight and high-strength.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
