[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] refer to Figure 1 According to the embodiment of the utility model, the high-strength clean panel includes a substrate 10, and the two sides of the substrate 10 are symmetrically connected with a sound insulation layer 20, a structural strength layer 30, a buffer protection layer, a mesh layer 50 and a protection plate 60 in sequence about the central axis of the substrate 10. A shielding frame 70 is sleeved on the circumference of the substrate 10, and a plurality of protrusions 71 are evenly connected to the two end surfaces of the shielding frame 70, respectively. A plurality of grooves 61 are evenly arranged on the opposite surfaces of the two protection plates 60, and the protrusions 71 are plugged into the grooves 61 one by one.

[0028] In actual use, the outer frame of the entire clean board is formed by setting the protection plate 60 and the enclosure frame 70, and the other layer structures symmetrically arranged around the substrate 10 provide the effects of sound insulation, noise reduction, structural strength improvement, and shock resistance and energy absorption, so that the clean board can reduce weight while having high strength and has good practicality.

[0029] refer to Figure 2 According to some embodiments of the present invention, the substrate 10 is hollow, and a plurality of sound-absorbing holes 11 are opened on the surface of the substrate 10 . The interior of the substrate 10 is filled with sound-absorbing cotton 12 , and the sound insulation layer 20 is made of foam metal.

[0030] Specifically, the sound-absorbing cotton 12 is made of polyester fiber, the foam metal material selected for the sound insulation layer 20 is foam aluminum material, and the substrate 10 is made of calcium silicate material. The polyester fiber is hot-pressed by high technology and is formed in the shape of cocoon cotton. The sound absorption coefficient can reach 0.94 within the noise range of 125-4000HZ. It has flexibility, heat preservation and flame retardancy, and is a good environmentally friendly material. When the sound wave enters the silencing space, it reacts with the silencing cotton, thereby effectively improving the silencing and noise reduction effect. At the same time, the foam metal has a series of good advantages such as low density, good heat insulation performance, good sound insulation performance, and the ability to absorb electromagnetic waves.

[0031] refer to Figure 2In order to further improve the silencing effect of the substrate 10 and the sound insulation layer 20, thereby effectively filtering low-frequency noise, according to some embodiments of the utility model, a plurality of hollow metal pillars 13 are further arranged inside the substrate 10, and a rubber sleeve 14 is sleeved on the outside of the metal pillar 13, and the length of the rubber sleeve 14 is the same as the length of the metal pillar 13. Specifically, the metal pillar 13 can be a stainless steel pillar. Through the above arrangement, the density difference between the substrate 10 and the metal pillar 13 is large, and the combination of the metal pillar 13 and the rubber sleeve 14 is a periodic structural functional material with an elastic wave bandgap. The starting frequency of the bandgap generated by it is very low, and the bandwidth between the starting and ending frequencies is wide. The low-frequency noise of this frequency will be isolated because it cannot pass through, thereby greatly improving the sound insulation of low-frequency noise. Under the excitation of low-frequency sound waves, the combination of the metal pillar 13 and the rubber sleeve 14 can produce resonance, interact with the incident sound wave, and prevent it from continuing to propagate, thereby achieving the effect of isolating low-frequency noise.

[0032] According to some embodiments of the present invention, a through hole 15 is formed on the circumference of the rubber sleeve 14. Through the provision of the through hole 15, a part of the sound waves directly contact the metal support 13 and resonate directly without passing through the rubber sleeve 14, so as to interact with a wider range of incident sound waves.

[0033] refer to Figure 4 According to some embodiments of the present invention, the mesh layer 50 includes a plurality of parallel transverse reinforcing ribs 51 and a plurality of longitudinal reinforcing ribs 52, and the transverse reinforcing ribs 51 and the longitudinal reinforcing ribs 52 are cross-overlapped to form a mesh structure. The mesh layer 50 is provided to effectively improve the overall anti-bending ability of the clean board.

[0034] According to some embodiments of the present invention, the structural strength layer 30 is a honeycomb panel. The honeycomb panel is provided to meet the overall structural strength and also can effectively reduce the weight of the overall structure, so that the clean panel can be lightweight.

[0035] According to some embodiments of the utility model, the buffer protection layer includes a first semicircular elastic rubber ring 41 and a second semicircular elastic rubber ring 42 which are arranged at equal intervals, the center of the first semicircular elastic rubber ring 41 is close to the substrate 10, and the center of the second semicircular elastic rubber ring 42 is close to the protection plate 60. The buffer protection layer is provided so that the clean plate has the function of shock resistance and energy absorption.

[0036] refer to Figure 3According to some embodiments of the utility model, the protective plate 60 includes a calcium silicate filler 62, a fiber mesh 63, two support frames and a calcium silicate coating layer 64, the two support frames are connected to two opposite inner walls of the calcium silicate coating layer 64, clamping members are arranged on opposite surfaces of the support frames, the fiber mesh 63 is connected to the clamping members, the calcium silicate filler 62 is filled and arranged in the calcium silicate coating layer 64, the groove 61 is opened on the calcium silicate coating layer 64, and the mesh layer 50 is connected to the calcium silicate coating layer 64.

[0037] Preferably, the clamping member includes an upper arc plate 65 and a lower arc plate 66 symmetrically arranged about the central axis of the support frame, the minimum spacing between the upper arc plate 65 and the lower arc plate 66 is less than the thickness of the fiber mesh 63, and the upper arc plate 65, the lower arc plate 66 and the support frame adopt an integrated structure.

[0038] Specifically, the fiber mesh 63 is made of nylon mesh or glass fiber mesh 63, and the support frame is made of aluminum alloy plate or flame-retardant plastic plate.

[0039] By setting up a support frame, the bending strength of the calcium silicate filler 62 can be improved along the length direction, and the fiber mesh 63 can be tensioned and maintained by the clamping components on the support frame to ensure the flatness of the fiber mesh 63 pre-buried in the calcium silicate filler 62, further improving the strength of the calcium silicate filler 62, with good load-bearing effect and a wide range of applications.

[0040] According to some embodiments of the utility model, a photocurable layer 81 and a texture layer 82 are sequentially arranged from the inside to the outside on the side of the calcium silicate coating layer 64 away from the mesh layer 50. The photocurable layer 81 is formed by irradiating the photocurable oil and photocurable ink coated on the surface of the calcium silicate coating layer 64 with ultraviolet rays. It has rich colors and is environmentally friendly and wear-resistant. It can also form a UV fluorocarbon coating and a nano silver ion sterilization layer, which are photocurable coatings with disinfection and sterilization effects. The specific technical solution can use the technical solution commonly used in the prior art, which will not be repeated here. At the same time, the texture layer 82 can provide the glossiness and touch texture required by customers, and this technical solution can also use the technical solution commonly used in the prior art.
