Description

Technical Field

[0001] This utility model relates to the field of wood-plastic composite boards, and specifically to a wear-resistant and shock-absorbing wood-plastic composite board. Background Technology

[0002] Currently, wood-plastic composite (WPC) boards are widely used in building decoration, furniture manufacturing, and other fields. However, existing WPC boards have certain shortcomings in terms of wear resistance and shock absorption, making it difficult to meet the performance requirements of some applications. For example, in public places with high foot traffic, ordinary WPC boards are easily worn, affecting aesthetics and lifespan. In some situations where vibration transmission needs to be reduced, such as industrial plant floors, existing WPC boards have poor shock absorption and require complete replacement after damage, resulting in high maintenance costs. Therefore, to address the shortcomings of existing technologies, a simple, wear-resistant, and shock-absorbing WPC board needs to be designed. Utility Model Content

[0003] This invention provides a wear-resistant and shock-absorbing wood-plastic composite board to address the problems of existing technologies.

[0004] The objective of this utility model can be achieved through the following technical solution: A wear-resistant and shock-absorbing wood-plastic composite board includes, from top to bottom, a wear-resistant layer, a shock-absorbing buffer layer, a substrate layer, and a support layer. The wear-resistant layer and the substrate layer are fixedly connected by snap fasteners. The shock-absorbing buffer layer is located inside the wear-resistant layer and the substrate layer. The substrate layer is fixed to the upper end of the support layer by adhesive bonding. The shock-absorbing buffer layer has a honeycomb cavity structure and an elastic filler. The elastic filler is disposed inside the honeycomb cavity structure. The upper surface of the support layer has longitudinal reinforcing ribs and transverse grooves. Metal damping sheets are embedded in the transverse grooves.

[0005] In a further improvement, the wear-resistant layer is a high-density wood-plastic composite material layer with a thickness of 0.5 to 2 mm, and the surface of the wear-resistant layer is provided with concave and convex anti-slip textures; the shock-absorbing and buffering layer is made of EPDM rubber or polyurethane foam material with a thickness of 3 to 8 mm.

[0006] In a further improvement, the substrate layer is a wood-plastic co-extruded core board, and bamboo fiber reinforced skeletons are uniformly distributed inside the substrate layer, with the bamboo fiber reinforced skeletons arranged in a three-dimensional mesh pattern.

[0007] In a further improvement, the bottom of the wear-resistant layer is provided with a T-shaped retaining strip, and the top of the substrate layer is provided with a dovetail groove. The T-shaped retaining strip and the dovetail groove are connected by an interference fit.

[0008] In a further improvement, the metal damping sheet is a corrugated stainless steel sheet with a thickness of 0.2 to 0.5 mm.

[0009] In a further improvement, the honeycomb cavity structure is arranged in a hexagonal unit array, with a unit side length of 3-8 mm and a cavity height of 50-80% of the thickness of the shock-absorbing buffer layer.

[0010] Compared with existing technologies, the beneficial effects of this wear-resistant and shock-absorbing wood-plastic composite board are as follows:

[0011] The wear-resistant layer provides surface protection for the wood-plastic composite board, reducing wear and extending its service life; the shock-absorbing buffer layer absorbs and disperses vibrations through its honeycomb cavity structure and elastic filler, reducing vibration transmission; the longitudinal reinforcing ribs and metal damping sheets of the support layer enhance the overall strength and stability of the wood-plastic composite board, while the metal damping sheets further reduce vibrations; the wear-resistant layer is connected to the substrate layer by means of snap-fit ​​and adhesive, resulting in a stable structure that is easy to install and maintain. Replacing the surface wear-resistant layer or the internal shock-absorbing buffer layer reduces maintenance costs. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] A wear-resistant and shock-absorbing wood-plastic composite board includes, from top to bottom, a wear-resistant layer 1, a shock-absorbing buffer layer 2, a substrate layer 3, and a support layer 4. The wear-resistant layer 1 and the substrate layer 3 are fixedly connected by snap-fit. The shock-absorbing buffer layer 2 is located inside the wear-resistant layer 1 and the substrate layer 3. The substrate layer 3 is fixed to the upper end of the support layer 4 by adhesive bonding. The shock-absorbing buffer layer 2 has a honeycomb cavity structure 21 and an elastic filler 22. The elastic filler 22 is disposed inside the honeycomb cavity structure 21. The upper surface of the support layer 4 has longitudinal reinforcing ribs 41 and transverse grooves 42. A metal damping sheet 43 is embedded in the transverse grooves 42.

[0022] like Figures 1-4 As shown, in this utility model, the wear-resistant layer provides surface protection for the wood-plastic composite board, reducing wear and extending its service life; the shock-absorbing buffer layer absorbs and disperses vibrations through a honeycomb cavity structure and elastic filler, reducing vibration transmission; the longitudinal reinforcing ribs and metal damping sheets of the support layer enhance the overall strength and stability of the wood-plastic composite board, while the metal damping sheets can further reduce vibration; the wear-resistant layer and the substrate layer are connected by snap-fit ​​and adhesive methods, resulting in a stable structure that is easy to install and maintain. Replacing the surface wear-resistant layer or the internal shock-absorbing buffer layer reduces maintenance costs.

[0023] As a further preferred embodiment, the wear-resistant layer 1 is a high-density wood-plastic composite material layer with a thickness of 0.5-2mm. The surface of the wear-resistant layer 1 is provided with concave-convex anti-slip texture 11. The wear resistance of high-density wood-plastic composite material is better than that of ordinary materials. The concave-convex anti-slip texture on the surface further increases the friction, prevents slipping, and improves safety. The shock-absorbing buffer layer 2 is made of EPDM rubber or polyurethane foam material with a thickness of 3-8mm. The elastic properties of EPDM rubber or polyurethane foam material can effectively absorb vibration and reduce the impact of vibration on the ground and the upper structure.

[0024] As a further preferred embodiment, the substrate layer 3 is a wood-plastic co-extruded core board, and bamboo fiber reinforcement skeletons are uniformly distributed inside the substrate layer 3. The bamboo fiber reinforcement skeletons are arranged in a three-dimensional mesh pattern. The bamboo fiber reinforcement skeletons improve the compressive strength and impact resistance of the substrate layer, enabling it to withstand greater loads. The three-dimensional mesh pattern of the bamboo fiber skeletons enhances the structural stability of the substrate layer and reduces the possibility of deformation and cracking.

[0025] As a further preferred embodiment, the bottom of the wear-resistant layer 1 is provided with a T-shaped retaining strip 12, and the top of the substrate layer 3 is provided with a dovetail groove 31. The T-shaped retaining strip 12 and the dovetail groove 31 are connected by an interference fit. The interference fit connection between the T-shaped retaining strip and the dovetail groove makes the connection between the wear-resistant layer and the substrate layer more secure, reducing wear and damage caused by loose connection. At the same time, the snap-fit ​​connection method facilitates installation and disassembly, reduces installation costs and maintenance difficulty, and improves work efficiency.

[0026] As a further preferred embodiment, the metal damping sheet 43 is a corrugated stainless steel sheet with a thickness of 0.2–0.5 mm. The corrugated stainless steel sheet metal damping sheet can effectively absorb and dissipate vibration energy, further reducing vibration transmission and improving the damping effect.

[0027] As a further preferred embodiment, the honeycomb cavity structure 21 is arranged in a hexagonal unit array, with a unit side length of 3-8 mm and a cavity height of 50-80% of the thickness of the shock-absorbing buffer layer 2. The hexagonal unit array honeycomb structure can evenly distribute stress, reduce stress concentration, and enable the shock-absorbing buffer layer to more effectively absorb and buffer vibrations when subjected to external forces. At the same time, it reduces the amount of material used, lowers the overall weight of the wood-plastic composite board, and facilitates transportation and installation.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
