Description

Technical Field

[0001] This utility model belongs to the field of panel technology, specifically relating to an environmentally friendly panel with a noise reduction structure. Background Technology

[0002] Decorative veneer plywood, also known as decorative panel or veneer board, is a decorative board made by precisely slicing solid wood into thin veneers with a thickness of 0.2mm or more, using plywood as the base material, and then gluing them together. It has a single-sided decorative function. The full name of veneer board is decorative veneer plywood, also known as patterned board or secondary processed board. Veneer board has a layered structure, including a pattern layer, a base layer, and a decorative layer, which are connected together by pressing and gluing.

[0003] A search revealed Chinese Patent Publication No. CN211334907U, which discloses a green and environmentally friendly veneer panel. The panel includes a body comprising a waterproof layer, an insulation layer, a wood panel layer, a decorative layer, and a varnish layer. The insulation layer is located on the surface of the waterproof layer, the wood panel layer is located on the surface of the insulation layer, the decorative layer is located on the surface of the wood panel layer, and the varnish layer is located on the surface of the decorative layer. This veneer panel, by incorporating the waterproof layer, insulation layer, wood panel layer, varnish layer, and protrusions and grooves, facilitates installation and solves the problems of existing veneers being environmentally unfriendly and having poor moisture resistance and insulation. However, due to the lack of sound-absorbing and noise-reducing structures, the overall noise reduction performance of the veneer panel is poor, thus failing to reduce the negative environmental impact on human health.

[0004] Therefore, it is of great importance to design an environmentally friendly panel with a noise reduction structure to solve the above-mentioned defects. Utility Model Content

This panel aims to solve the technical problem that the existing panel lacks a sound-absorbing and noise-reducing structure, resulting in poor overall noise reduction performance.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly panel with a noise reduction structure. The panel includes a core body, which is composed of a substrate, a damping adhesive layer, a honeycomb sandwich panel, and a sponge layer. A set of frame edges is inserted into both sides of the core body. A T-shaped groove is provided on the left side of the frame edge, and a T-shaped slider is fixedly connected to the right side of the frame edge at a position corresponding to the T-shaped groove. A limit strip is fixedly connected to the side of the left frame edge away from the right frame edge, and an assembly groove is provided on the side of the right frame edge away from the left frame edge. Decorative panel layers are adhered to both the front and back sides of the core body.

[0009] When using the panel with this technical solution, the porous structure of the sponge layer absorbs noise, and the damping adhesive layer dissipates vibration energy through shear deformation, thereby reducing noise propagation. The honeycomb sandwich panel enhances the structural strength and bending resistance of the core body. Adjacent groups of panels in the horizontal direction are assembled and connected by sliding T-shaped sliders and T-shaped grooves. Adjacent groups of panels in the vertical direction are limited by limiting strips and assembly grooves, improving the ease of assembly and connection strength between panels.

[0010] Preferably, the surface of the sponge layer has a plurality of sound-absorbing holes.

[0011] Furthermore, a honeycomb sandwich panel is bonded to both sides of the sponge layer, a damping adhesive layer is bonded to the side of the honeycomb sandwich panel away from the sponge layer, and a substrate is bonded to the side of the damping adhesive layer away from the honeycomb sandwich panel.

[0012] Furthermore, the two sets of frame edges are slidably connected by a T-shaped slider and a T-shaped groove.

[0013] Furthermore, a set of telescopic grooves is provided at the top and bottom of the limiting strip. A spring assembly is installed inside the telescopic groove. A trapezoidal block is fixedly connected to the side of the spring assembly away from the telescopic groove. Limiting slots are provided on both sides of the inner wall of the assembly groove at positions corresponding to the trapezoidal block. The trapezoidal block engages with the limiting slot.

[0014] Furthermore, two pairs of mating strips are fixedly connected to the corresponding side of the left and right side of the frame. The right side of the frame has mating holes at the corresponding positions of the mating strips. The left and right sides of the frame are connected by mating strips and mating holes.

[0015] Furthermore, the outer side of the decorative panel layer is provided with an environmentally friendly waterproof paint layer.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The panel of this utility model absorbs noise through the sound-absorbing holes of the sponge layer, and the damping adhesive layer dissipates vibration energy through shear deformation, thereby reducing noise transmission.
