Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic board technology, specifically to a sound-insulating rubber and plastic board with moisture-proof and waterproof joints. Background Technology

[0002] In modern construction, industrial equipment, and transportation, the performance requirements for materials are increasingly stringent, particularly in terms of waterproofing, sound insulation, and structural stability. Rubber and plastic boards, as a commonly used functional material, are widely applied in applications such as wall sound insulation, pipe insulation, and equipment vibration damping.

[0003] Currently, most rubber and plastic boards are joined using adhesive. Uneven application of adhesive can affect the firmness of the joints, creating gaps. Furthermore, the waterproofing effect at these gaps is poor, and over time, moisture can affect the adhesion, further compromising the overall strength of the joints and impacting their performance.

[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] Example 1

[0021] Please see Figure 1 and Figure 4 A sound-insulating rubber and plastic board with moisture-proof and waterproof joints includes a rigid layer 10, a top soft layer 20 and a bottom soft layer 30, wherein the top soft layer 20 and the bottom soft layer 30 are respectively bonded and fixed above and below the rigid layer 10.

[0022] In this embodiment, the hard layer 10 can be made of material with a density of 800-1200 kg / m³. 3 Made of high-density polyvinyl chloride material with a Young's modulus of 1.5-3.0 GPa, the rigid layer 10 improves high-frequency sound insulation during sound wave transmission. The rigid layer 10 also has spaced-apart honeycomb pore groups 11 that penetrate the entire layer. The opening of the honeycomb pore groups 11 on the surface of the rigid layer 10 creates a cavity structure that converts sound wave energy into heat energy, thereby improving sound insulation. Furthermore, the pore size in the honeycomb pore groups 11 gradually decreases from the surface to the core layer, forming a sound wave refraction gradient, further enhancing mid-to-high frequency sound insulation performance. Multiple first sealing protrusions 12 are spaced apart on the adjacent outer walls of the rigid layer 10, and multiple second sealing protrusions 13 are spaced apart on the other adjacent outer walls of the rigid layer 10. The first sealing protrusion 12 and the second sealing protrusion 13 are staggered relative to each other along the thickness direction of the hard layer 10, and the gap between two adjacent first sealing protrusions 12 is adapted to the thickness of the second sealing protrusion 13, and the spacing between two adjacent second sealing protrusions 13 is adapted to the thickness of the first sealing protrusion 12. Furthermore, the widths of the first sealing protrusions 12 and the second sealing protrusions 13 are equal, and the lengths of both the first sealing protrusions 12 and the second sealing protrusions 13 are equal to the length or width of the hard layer 10. (See also...) Figure 3 When multiple rubber-plastic panels are spliced ​​together, the adjacent first sealing protrusions 12 and second sealing protrusions 13 of two adjacent rubber-plastic panels can be interlocked, forming a series of narrow, tortuous channels and constituting a labyrinthine seal. This seal reduces water infiltration through throttling and expansion effects. After splicing, sealant can be applied to the joints of adjacent rubber-plastic panels to further improve the seepage prevention effect. In the spliced ​​multiple rubber-plastic panels, epoxy resin is applied to the second sealing protrusion 13 at the top of the outermost rubber-plastic panel, and the epoxy resin is allowed to solidify and become flush with the top surface of the rubber-plastic panel, thus keeping the upper surface of the spliced ​​multiple rubber-plastic panels flat.

[0023] In this embodiment, both the top soft layer 20 and the bottom soft layer 30 can be made of materials with a density of 150-300 kg / m³. 3It is made of closed-cell foam rubber sheet with an elastic modulus of 0.1-0.5 MPa. Its closed-cell structure can effectively block the transmission of airborne sound and improve the low-frequency sound insulation effect when sound waves are transmitted. In addition, the low elastic modulus can absorb the structural vibration energy through deformation. The above-mentioned closed-cell foam rubber sheet can be made of materials such as polyurethane or EPDM rubber.

[0024] Example 2

[0025] See Figure 2 Based on Embodiment 1, the sound-insulating rubber-plastic board with moisture-proof and waterproof joints in this embodiment further includes a first damping interlayer 40 and a second damping interlayer 50. The first damping interlayer 40 is disposed between the top soft layer 20 and the hard layer 10 and is bonded and fixed to both layers. The second damping interlayer 50 is disposed between the hard layer 10 and the bottom soft layer 30 and is bonded and fixed to both layers. Both the first damping interlayer 40 and the second damping interlayer 50 can be made of butyl rubber sheet. The placement of the first damping interlayer 40 and the second damping interlayer 50 can improve the sound insulation effect by consuming sound energy through internal friction of the material during sound wave transmission.

[0026] In all the solutions mentioned above, for connections between two components, welding, bolt and nut connection, bolt or screw connection, or other known connection methods can be selected according to the actual situation, which will not be elaborated here. For all fixed connections mentioned above, bonding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
