Description

Technical Field

[0001] The utility model relates to the technical field of plastic plates, in particular to a new material plastic plate with a sound-absorbing function. Background Art

[0002] Plastic board refers to a board made of plastic material, and the key component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. Its molecular structure is unique and has specific physical and chemical properties. Plastic board has been widely used in many important fields due to its many significant advantages. In the chemical industry, plastic board can resist the erosion of various chemical substances due to its excellent corrosion resistance. It is used to manufacture chemical containers, pipelines and linings of reaction equipment, etc., effectively extending the service life of equipment and ensuring the safety and stability of chemical production. The pharmaceutical field has extremely high requirements for the purity and safety of materials. Plastic board is often used to make medical device shells, pharmaceutical packaging materials, etc. due to its good hygiene and chemical stability, to ensure the quality and safety of medical supplies. In the electronics industry, the insulation performance advantages of plastic board are fully utilized. It is used to manufacture electronic equipment shells, insulating supports for circuit boards, etc., to provide reliable protection for electronic components, while preventing problems such as leakage and short circuits. In the decoration field, plastic board is favored for its rich colors, diverse textures and easy processing. It can be processed into various shapes and patterns and used for wall decoration, furniture surface covering, ceiling materials, etc., adding beauty and personality to the interior space.

[0003] Plastic boards have certain properties in terms of sound insulation. The main reasons why plastic boards can play a certain role in sound insulation are as follows: Density factor: Some plastic boards have a relatively high density, which helps to block the propagation of sound. Higher density can reduce the penetration of sound waves, thereby weakening the energy of sound. Damping characteristics: The plastic material itself has certain damping properties, which can absorb and dissipate the vibration energy of sound waves and reduce the propagation of sound. However, the sound insulation effect of plastic boards also has certain limitations: The effect of a single material is limited: Using plastic boards alone may not achieve a very ideal sound insulation effect, especially for the blocking of low-frequency sounds. Sealing effect: In actual applications, if the installation is not sealed enough, the sound may be transmitted through the gap, weakening the overall sound insulation performance.

[0004] Existing plastic boards generally increase the thickness of the board to block the propagation of sound, or fill the board with sound insulation cotton for sound insulation treatment. This results in the thickness and weight of the sound-absorbing board to greatly affect the use of the plastic board, and a single material plastic board cannot effectively block external sound. Summary of the invention

[0005] In order to make up for the above shortcomings, the utility model provides a new material plastic plate with a sound-absorbing function, aiming to improve the problem that the thickness and weight of the sound-absorbing plastic plate in the prior art affect the installation of workers, and the sound-absorbing effect of the plastic plate of a single material is poor.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new material plastic plate with a sound-absorbing function, comprising a panel, wherein upper side panels are fixedly connected to the left and right sides of the bottom end of the panel, a honeycomb structure mesh panel is fixedly connected to the bottom end of the panel, the honeycomb holes of the honeycomb structure mesh panel are filled with sound-insulating felt, the bottom end of the upper side panel is fixedly connected to sound-insulating silica gel, the left and right sides of the bottom end of the sound-insulating silica gel are fixedly connected to lower side panels, the bottom end of the lower side panel is fixedly connected to a bottom plate, a number of support plates are fixedly connected between the sound-insulating silica gel and the bottom plate at equal distances from left to right, and corrugated sound-insulating cotton is fixedly connected to the top and bottom between the support plates.

The panel 1 is supported by the honeycomb structure mesh plate 5, and the bottom plate 2 is supported by the support plate 8, so that the upper and lower parts of the sound-absorbing plastic plate form a hollow state, thereby reducing the weight and thickness of the plastic plate and reducing the labor intensity of workers during installation.

[0026] The honeycomb holes of the honeycomb structure mesh panel 5 are filled with sound insulation felt 6, the bottom end of the upper side panel 3 is fixedly connected to sound insulation silicone rubber 7, the left and right sides of the bottom end of the sound insulation silicone rubber 7 are fixedly connected to the lower side panel 4, the bottom end of the lower side panel 4 is fixedly connected to the bottom plate 2, and a number of support plates 8 are fixedly connected between the sound insulation silicone rubber 7 and the bottom plate 2 at equal intervals from left to right, and wave sound insulation cotton 9 is fixedly connected to the top and bottom between the support plates 8. When an external sound source propagates, when the sound wave contacts the panel 1, it is first weakened by the honeycomb structure mesh panel 5 in the panel 1, and then absorbed by the sound insulation felt in the honeycomb holes. At the same time, the resonance of the panel 1 caused by the sound wave is buffered by the sound insulation silicone rubber 7. Finally, the residual sound waves are blocked and absorbed by the wave sound insulation cotton 9 to complete the removal of external noise.

At the same time, the fixing card slot 11 on the lower plastic plate covers the screw fixing plate 10 to improve the aesthetics of the plastic plate.

[0028] Working principle: the panel 1 is supported by the honeycomb structure mesh plate 5, and the bottom plate 2 is supported by the support plate 8, so that the upper and lower parts of the sound-absorbing plastic plate form a hollow state, which reduces the weight and thickness of the plastic plate and the labor intensity of workers during installation. When the workers install it, they fix the plastic plate to the wall with screws through the screw fixing plate 10, and then clamp the silicone card block 13 on the silicone card groove 12 on the upper plastic plate. At the same time, the fixing card groove 11 on the lower plastic plate covers the screw fixing plate 10 to improve the aesthetics of the plastic plate. When the external sound source propagates, when the sound wave contacts the panel 1, it is first weakened by the honeycomb structure mesh plate 5 in the panel 1, and then absorbed by the sound insulation felt in the honeycomb hole. At the same time, the resonance of the panel 1 caused by the sound wave is buffered by the sound insulation silicone 7.
