DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figs. 1 to 4 As shown, the utility model provides a honeycomb sound barrier panel structure, including an external frame 1, a circular hole 101 is opened at the bottom of the external frame 1, and the circular holes 101 are distributed in an array along the bottom surface of the external frame 1, and a back plate 2 is installed on the top of the external frame 1, a first sound-absorbing layer 3 is installed at the bottom of the inner wall of the external frame 1, a second sound-absorbing layer 4 is installed on the top of the first sound-absorbing layer 3, a honeycomb sound-absorbing layer 5 is installed on the top of the second sound-absorbing layer 4, and an impact-resistant layer 6 is installed on the top of the honeycomb sound-absorbing layer 5. The first sound-absorbing layer 3 is made of polypropylene foam material, the second sound-absorbing layer 4 is made of polyester fiber material, the honeycomb sound-absorbing layer 5 is made of aluminum honeycomb panel, and the impact-resistant layer 6 is made of polycarbonate material.

[0022] In the embodiment of the present application, noise enters the interior of the outer frame 1 and then the interior of the first sound-absorbing layer 3 through the circular hole 101. Due to the porous structure of the polypropylene foam material, the sound waves are dispersed, reflected, and absorbed by the air and pores within the material. The closed-cell structure of the foam can effectively reduce sound reflection and reduce noise transmission. The structure of the foam converts the energy of the sound waves into heat energy or the vibration energy of the internal gas, thereby reducing the transmission intensity of the sound. It is suitable for absorbing and soundproofing low-frequency noise. Secondly, the polypropylene foam has good thermal insulation effect.

[0023] Polyester fiber materials are typically composed of a large number of fibers interwoven together to form a dense mesh structure with abundant air pores. Once sound waves enter this fiber structure, they are scattered, refracted, and absorbed between the fibers and pores, effectively reducing sound transmission and converting noise energy into heat, making them suitable for absorbing mid- and high-frequency noise.

[0024] Polypropylene foam and polyester fiber materials can also improve the thermal insulation performance of the noise barrier board.

[0025] The honeycomb sound-absorbing layer 5 has a unique structure, and the honeycomb shape inside can effectively disperse and absorb sound waves, thereby reducing the propagation of noise, and due to the honeycomb structure, higher strength and rigidity can be provided without increasing excessive weight, and the impact resistance layer 6 has long molecular chains and high flexibility, and can absorb and disperse impact energy through molecular chain movement when impacted. This structure enables the impact resistance layer 6 to withstand greater external force without being easily broken or broken, thereby further improving the impact resistance of the noise barrier plate.

[0026] The bottom of the outer frame 1 is coated with an antibacterial coating 102, and the antibacterial coating 102 adopts a silver ion coating material.

[0027] Through the design of the silver ion coating, the noise barrier can reduce the spread of bacteria, viruses and other pathogens, and keep the air clean.

[0028] The top of the inner wall of the outer frame 1 is coated with an antistatic coating 103, and the antistatic coating 103 adopts a graphite material.

[0029] Through the setting of the antistatic coating 103, the surface of the outer frame 1 can be prevented from accumulating static electricity, thereby eliminating static electricity and avoiding causing safety accidents.

[0030] The top of the outer frame 1 is provided with a mounting groove 11, and the bottom of the back plate 2 is fixedly connected with a back-shaped frame 201, the back-shaped frame 201 and the mounting groove 11 are matched with each other, and the inside of the mounting groove 11 is provided with an adhesive, and the adhesive adopts an epoxy resin material.

[0031] When the outer frame 1 and the back plate 2 are installed, the adhesive is filled in the inside of the mounting groove 11, then the back-shaped frame 201 is inserted into the inside of the mounting groove 11, and after the adhesive is cured, the back plate 2 forms a seal to the inside of the outer frame 1.

[0032] The surfaces of the first sound-absorbing layer 3 and the second sound-absorbing layer 4 are coated with a fireproof coating, and the fireproof coating adopts a polyurethane material.

[0033] Through the setting of the fireproof coating, the fire resistance of the first sound-absorbing layer 3 and the second sound-absorbing layer 4 can be increased, the burning speed of the material in the fire and the flame propagation can be reduced, and the fire resistance of the noise barrier can be improved, thereby effectively reducing the fire risk and protecting the safety of buildings and personnel.

[0034] The working principle and use process of the utility model are as follows:

[0035] Noise enters into the inside of the outer frame 1 through the circular hole 101 and enters into the inside of the first sound-absorbing layer 3, due to the porous structure inside the polypropylene foam material, the sound wave will be dispersed, reflected and absorbed by the air and pores inside the material. The closed cell structure of the foam can effectively reduce the reflection of sound and reduce the propagation of noise. The structure of the foam converts the energy of the sound wave into heat energy or internal gas vibration energy, which can reduce the propagation intensity of the sound, suitable for low-frequency noise absorption and sound insulation. Secondly, the polypropylene foam has good heat insulation effect,

[0036] The polyester fiber material is usually composed of a large number of interwoven fibers, forming a dense network structure with abundant air pores. When the sound wave enters the fiber structure, the sound wave is scattered, refracted and absorbed between the fibers and the pores, which can effectively weaken the propagation of sound and convert the energy of noise into heat energy, suitable for absorbing medium and high frequency noise;

[0037] The honeycomb sound-absorbing layer 5 has a unique structure, and the honeycomb shape inside can effectively disperse and absorb sound waves, thereby reducing the propagation of noise. Due to the honeycomb structure, it can provide high strength and rigidity without increasing too much weight, and has good impact resistance. At the same time, the molecular chain of the impact-resistant layer 6 is long and has high flexibility, which can absorb and disperse impact energy through the movement of molecular chains when impacted. This structure enables the impact-resistant layer 6 to withstand a large external force without being easily broken or broken, thereby further improving the impact resistance of the noise barrier plate.
