Description

Technical Field

[0001] This utility model relates to the field of PVC foam board technology, and in particular to a sound insulation board made of PVC foam board. Background Technology

[0002] PVC foam board is a porous board made of polyvinyl chloride as the main raw material and foaming agent and other additives. It is lightweight and has certain heat insulation and moisture-proof properties. It is often used as padding, partition and other materials in packaging, decoration and construction. It can play a basic role in separation and support in certain scenarios.

[0003] However, PVC foam boards have poor sound insulation performance and are difficult to effectively block or absorb sound waves, especially in terms of handling low and medium frequency noise. In addition, their own strength is limited, and they are prone to deformation or breakage under external force or long-term load. Therefore, we propose a sound insulation board made of PVC foam boards to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing PVC foam boards, such as poor sound insulation performance, difficulty in blocking and absorbing sound waves, especially insufficient ability to handle low and medium frequency noise, and limited strength, which makes them prone to deformation and breakage under external force or long-term load. Therefore, a sound insulation board made of PVC foam board is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sound insulation board made of PVC foam board includes an upper sound insulation board, a lower sound insulation board, and a PVC foam board.

[0007] The bottom of the upper sound insulation board and the top of the lower sound insulation board are provided with grooves, which form a cavity when they are joined together, and the PVC foam board is placed in the cavity;

[0008] The top and bottom surfaces of the PVC foam board are arrayed with resonant micropores.

[0009] The inner walls of both grooves are provided with reinforcing ribs, and both reinforcing ribs abut against the PVC foam board;

[0010] The upper and lower sound insulation panels are each provided with two sets of fixing components on all four sides. The fixing components include a locking block and corresponding slots opened on the sound insulation panel and the lower sound insulation panel.

[0011] The top of the upper sound insulation panel and the bottom of the lower sound insulation panel are bonded with decorative layers.

[0012] In one possible design, the slots are merged to form a wedge-shaped groove, and the card block is engaged with the wedge-shaped groove.

[0013] In one possible design, sealing grooves are formed at the bottom of the upper sound insulation panel and the top of the lower sound insulation panel, and the same sealing strip is embedded in both sealing grooves.

[0014] In one possible design, the reinforcing ribs of the upper sound insulation panel are transverse ribs, and the reinforcing ribs of the lower sound insulation panel are longitudinal ribs.

[0015] In one possible design, the inner side of the decorative layer is provided with a nano flame-retardant coating.

[0016] In one possible design, the inner wall of the groove is provided with a hot melt adhesive carbon fiber layer, and the thickness of the hot melt adhesive carbon fiber layer is less than the height of the reinforcing rib to prevent clogging.

[0017] In this application, a PVC foam board is placed in the groove of the lower sound insulation board, which forms a bottom support. The top surface of the longitudinal reinforcing rib of the lower sound insulation board abuts against the bottom surface of the PVC foam board, providing longitudinal support, enhancing structural strength, and preventing the foam board from shifting and affecting sound insulation. The upper sound insulation board is then placed on top, forming a top support. Its transverse reinforcing ribs abut against the top of the foam board, and the transverse and longitudinal reinforcing ribs provide cross support, enhancing structural rigidity and reducing deformation. At the same time, a hot melt adhesive carbon fiber layer is provided on the inner wall of the groove of the upper and lower sound insulation boards. The carbon fibers in the hot melt adhesive carbon fiber layer are oriented along the plane of the sound insulation board, and its axial negative expansion characteristics partially offset the expansion difference between the PVC foam board and the single sound insulation board in the XY plane. The thickness of the hot melt adhesive carbon fiber layer is less than the height of the reinforcing ribs, ensuring that the hot melt adhesive carbon fiber layer does not contact the resonant micropores and preventing the colloid from clogging the resonant micropores.

[0018] Meanwhile, the sealing grooves of the upper and lower sound insulation panels are aligned, and the sealing strips are embedded to enhance the sealing performance and prevent sound wave leakage. The locking blocks are inserted into the four wedge-shaped grooves to fix the upper and lower sound insulation panels and improve stability. The decorative layer provides an aesthetic effect, and the nano flame-retardant coating plays a fire-resistant role when exposed to fire, improving safety. All the structures work together to achieve stable and efficient sound insulation.

[0019] Beneficial effects: In this utility model, the sound insulation board made of PVC foam board has a PVC foam board built into the cavity formed by the merging of the upper and lower sound insulation boards. Combined with the resonant micropores at the top and bottom of the PVC foam board, it absorbs sound waves of specific frequencies, thereby improving the overall sound insulation effect and making it suitable for noisy environments.

[0020] In this utility model, the sound insulation board made of PVC foam board provides outer support for the PVC foam board through the upper and lower sound insulation boards. The reinforcing ribs on the inner wall of the groove abut against the foam board, and the transverse and longitudinal ribs are distributed in a cross pattern to provide stable support from different directions, greatly enhancing the structural strength and reducing the risk of deformation and breakage.

[0021] In this utility model, the sound insulation board made of PVC foam board is fastened by the four-sided fixing components and the wedge-shaped groove formed by the upper and lower sound insulation boards, which improves the stability of the assembly of the upper and lower sound insulation boards and extends the service life. At the same time, the nano flame-retardant coating improves the fire resistance.

[0022] In this invention, the upper and lower sound insulation panels are combined to form a cavity structure with an internal PVC foam board. The resonant micropores on the surface of the foam board absorb sound waves of specific frequencies, and the cavity provides sound insulation, thus improving the sound insulation effect to adapt to noisy environments. The reinforcing ribs distributed horizontally and vertically on the inner walls of the upper and lower sound insulation panels provide stable support for the foam board from different directions. The four-sided wedge-shaped grooves and locking blocks not only enhance the structural strength but also improve the assembly stability. At the same time, the nano flame-retardant coating on the outer surface improves the fire resistance. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Refer to Figure 1-4 A sound insulation panel includes an upper sound insulation panel 1, a lower sound insulation panel 2, and a PVC foam board 3. Grooves are formed at the bottom of the upper sound insulation panel 1 and the top of the lower sound insulation panel 2. When the upper sound insulation panel 1 and the lower sound insulation panel 2 are joined together, the two grooves form a cavity, within which the PVC foam board 3 is placed. This cavity structure can block sound wave transmission, improving the overall sound insulation effect to adapt to noisy environments.

[0030] Multiple resonant micropores 301 are arrayed at the top and bottom of the PVC foam board 3. These micropores absorb sound waves of specific frequencies, enhancing sound insulation performance. Multiple reinforcing ribs 7 are provided on the inner walls of the grooves at the bottom of the upper sound insulation board 1 and the top of the lower sound insulation board 2, and these ribs 7 all abut against the PVC foam board 3. The reinforcing ribs 7 on the upper sound insulation board 1 are transverse ribs, while those on the lower sound insulation board 2 are longitudinal ribs. The transverse and longitudinal ribs are intersecting, providing stable support to the PVC foam board 3 from different directions, significantly enhancing structural strength and reducing the risk of deformation and breakage.

[0031] Both the upper sound insulation panel 1 and the lower sound insulation panel 2 have two sets of fixing components on their four sides. Each fixing component includes a locking block 8 and a corresponding slot on one side of each panel. When the upper sound insulation panel 1 and the lower sound insulation panel 2 are joined together, the corresponding slots on the upper and lower panels form a wedge-shaped groove, and the locking block 8 engages with the corresponding wedge-shaped groove. This engagement method improves the stability of the assembly of the upper and lower sound insulation panels 1 and extends their service life.

[0032] A decorative layer 6 is adhered to the top of the upper sound insulation panel 1 and the bottom of the lower sound insulation panel 2. The decorative layer 6 directly provides the appearance effect without the need for additional surface treatment. Sealing grooves are provided at the bottom of the upper sound insulation panel 1 and the top of the lower sound insulation panel 2. Sealing strips 9 are fixedly embedded in the two sealing grooves. The sealing strips 9 can enhance the overall sealing performance and prevent sound wave leakage.

[0033] This application can be used in the field of PVC foam board technology, or in other fields applicable to this application.

[0034] In another embodiment: Reference Figure 2-4 An improvement based on Example 1: A sound insulation board made of PVC foam board, applied in the field of PVC foam board technology, wherein a nano flame-retardant coating 5 is provided on the top of the upper sound insulation board 1 and the bottom of the lower sound insulation board 2 between the decorative layer 6. The nano flame-retardant coating 5 can play a fireproof role when exposed to fire, improving the safety of use. A hot melt adhesive carbon fiber layer 4 is provided on the inner wall of the groove on the bottom of the upper sound insulation board 1 and the top of the lower sound insulation board 2. The carbon fibers in the hot melt adhesive carbon fiber layer 4 are oriented along the plane of the sound insulation board, and its axial negative expansion characteristics partially offset the expansion difference between the PVC foam board 3 and the single sound insulation board in the XY plane. Moreover, the thickness of the hot melt adhesive carbon fiber layer 4 is less than the height of the reinforcing rib 7, ensuring that the hot melt adhesive carbon fiber layer 4 does not come into contact with the resonant micropores 301, avoiding the colloid clogging the resonant micropores 301.

[0035] During assembly, the PVC foam board 3 is placed into the groove of the lower sound insulation board 2, forming a bottom support. The top surface of the longitudinal reinforcing rib 7 of the lower sound insulation board 2 abuts against the bottom surface of the PVC foam board 3, providing longitudinal support, enhancing structural strength, and preventing the PVC foam board 3 from shifting and affecting sound insulation. The upper sound insulation board 1 is then placed on top, forming a top support. Its transverse reinforcing rib 7 abuts against the top of the PVC foam board 3, and the transverse and longitudinal reinforcing ribs 7 provide cross-support, enhancing structural rigidity and reducing deformation. Then, the sealing grooves of the upper sound insulation board 1 and the lower sound insulation board 2 are aligned, the sealing strip 9 is embedded, and the clips 8 are inserted into the wedge-shaped grooves on all four sides to complete the fixing.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
