Description

Technical Field

[0001] This utility model relates to the technical field of wood-plastic composite boards, and in particular to a high-temperature resistant wood-plastic composite board. Background Technology

[0002] Wood-plastic composite boards, also known as wood-plastic composite panels, are a high-tech, green, and environmentally friendly material made from wood (wood cellulose, plant cellulose) as the base material and formed by heating and extruding through mold equipment.

[0003] Chinese Patent Publication No. CN217896790U, published on November 25, 2022, discloses a high-temperature resistant outdoor wood-plastic composite (WPC) board. The WPC board body has a fixed adjustment mechanism that is movably connected at its front and rear ends. Adjustable support mechanisms are installed on the upper and lower internal walls of the WPC board body. Corrugated embedded plates are symmetrically fixedly connected to both sides of the WPC board body. The drawback of this invention is that when used outdoors, direct sunlight may cause the WPC board to overheat locally. Insufficient heat dissipation can lead to deformation, cracking, fading, and brittleness of the material. Utility Model Content

[0004] The present invention aims to overcome the problems of existing wood-plastic composite boards being unable to withstand high temperatures, having slow heat dissipation, and exhibiting deformation, cracking, fading, and brittleness. It provides a high-temperature resistant wood-plastic composite board with fast heat dissipation.

[0005] To achieve the above objectives, this utility model provides a high-temperature resistant wood-plastic composite board, comprising:

[0006] The plastic board body has several heat dissipation cavities inside. The heat dissipation cavities are evenly distributed side by side inside the plastic board body and are flush with the left and right ends of the plastic board body. Adjacent heat dissipation cavities are connected to each other. A silicone cloth layer is installed on the upper surface of the plastic board body and is bonded to the plastic board body.

[0007] The heat dissipation chambers are used to diffuse heat from the wood-plastic composite (WPC) board, improving its heat dissipation function and high-temperature resistance. The interconnected chambers allow for even heat distribution, preventing localized overheating that could cause deformation or cracking. The high heat resistance of the silicone cloth layer further enhances the WPC board's high-temperature performance. This design makes the WPC board both heat-resistant and provides rapid heat dissipation.

[0008] Preferably, an aluminum plate is installed inside the wood-plastic composite (WPC) board body. The aluminum plate is located at the upper end of the heat dissipation cavity and is fixedly connected to the WPC board body. The aluminum plate has good thermal conductivity, which is used for heat dissipation of the WPC board body, allowing hot air to flow between the heat dissipation cavities, avoiding localized high temperatures, and improving the high-temperature resistance of the WPC board. This design makes the WPC board resistant to high temperatures and has a fast heat dissipation effect.

[0009] Preferably, the plastic-plastic board body also includes a support plate, which is placed between two adjacent heat dissipation cavities. The support plate has several first vent holes evenly distributed along its centerline, and adjacent heat dissipation cavities are connected through these first vent holes. The support plate enhances the load-bearing capacity of the plastic-plastic board body, and the first vent holes connect the heat dissipation cavities, preventing localized high temperatures and improving the high-temperature resistance of the plastic-plastic board. This design improves the structural stability of the plastic-plastic board, while also making it more heat-resistant and providing rapid heat dissipation.

[0010] Preferably, the lower end of the wood-plastic composite board body is provided with a plurality of second vent holes. These second vent holes are distributed on the lower end surface of each heat dissipation cavity, and are evenly distributed along the center line of the lower end surface of the heat dissipation cavity. The second vent holes are used to dissipate heat to the bottom of the wood-plastic composite board body, further dispersing the hot air and improving the high-temperature resistance of the wood-plastic composite board. This design makes the wood-plastic composite board resistant to high temperatures and provides rapid heat dissipation.

[0011] Preferably, the upper end of the wood-plastic composite board body is provided with several anti-slip grooves, which are evenly distributed along the upper surface of the wood-plastic composite board body. The silicone cloth layer is respectively installed on the upper surface of the wood-plastic composite board body and in the anti-slip grooves. The anti-slip grooves are used to improve the aesthetics of the wood-plastic composite board while preventing slippage, thus improving the safety of the wood-plastic composite board. This design improves both the aesthetics and safety of the wood-plastic composite board.

[0012] Preferably, the anti-slip groove has mounting grooves at both ends, and connecting plates are detachably installed in the mounting grooves. The mounting grooves and connecting plates cooperate to fix the wood-plastic composite board to the next wood-plastic composite board, avoiding large gaps between the boards and improving the stability between them. This design improves the stability between wood-plastic composite boards.

[0013] Preferably, the mounting groove includes a horizontal groove and a vertical groove, and the connecting plate includes a first vertical plate, a second vertical plate, and a horizontal plate. One end face of the first vertical plate is connected to one end sidewall of the horizontal plate, and one end face of the second vertical plate is connected to the other end sidewall of the horizontal plate. The first vertical plate matches the vertical groove of the wood-plastic composite board body, the second vertical plate matches the vertical groove of the next wood-plastic composite board body, and the horizontal plate matches the horizontal groove. This design improves the stability between wood-plastic composite boards.

[0014] Preferably, the upper surface of the horizontal plate is flush with the upper surface of the horizontal groove. This design improves the aesthetics of the wood-plastic composite board and prevents the connecting plate from colliding with the user.

[0015] The beneficial effects of this utility model are: the fast heat dissipation improves the high temperature resistance, aesthetics and safety of the wood-plastic composite board, while also ensuring structural stability. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, a high-temperature resistant wood-plastic composite board includes:

[0026] The plastic board body 1 has several heat dissipation cavities 2 inside it. The heat dissipation cavities 2 are evenly distributed in parallel inside the plastic board body 1 and are flush with the left and right ends of the plastic board body 1. Adjacent heat dissipation cavities 2 are connected to each other. A silicone cloth layer 3 is installed on the upper surface of the plastic board body 1 and is bonded to the plastic board body 1.

[0027] like Figure 1 and Figure 2As shown, an aluminum plate 4 is installed inside the plastic board body 1. The aluminum plate 4 is located at the upper end of the heat dissipation cavity 2 and is fixedly connected to the plastic board body 1. A support plate 5 is also provided inside the plastic board body 1. The support plate 5 is placed between two adjacent heat dissipation cavities 2. The support plate 5 is provided with several first ventilation holes 6. The first ventilation holes 6 are evenly distributed along the center line of the support plate 5. Adjacent heat dissipation cavities 2 are connected through the first ventilation holes 6.

[0028] like Figure 3 As shown, the lower end of the plastic board body 1 is provided with a number of second ventilation holes 7. The second ventilation holes 7 are distributed on the lower end surface of each heat dissipation cavity 2. The second ventilation holes 7 are evenly distributed along the center line of the lower end surface of the heat dissipation cavity 2.

[0029] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the upper end of the plastic board body 1 is provided with several anti-slip grooves 8, which are evenly distributed along the upper surface of the plastic board body 1. The silicone cloth layer 3 is respectively installed on the upper surface of the plastic board body 1 and in the anti-slip grooves 8. The anti-slip grooves 8 are provided with mounting grooves 9 at both ends. A connecting plate 12 is detachably installed in the mounting groove 9. The mounting groove 9 includes a horizontal groove 10 and a vertical groove 11. The connecting plate 12 includes a first vertical plate 13, a second vertical plate 14 and a horizontal plate 15. One end face of the first vertical plate 13 is connected to one end side wall of the horizontal plate 15, and one end face of the second vertical plate 14 is connected to the other end side wall of the horizontal plate 15. The first vertical plate 13 matches the vertical groove 11 of the plastic board body 1, the second vertical plate 14 matches the vertical groove 11 of the next plastic board body 1, and the horizontal plate 15 matches the horizontal groove 10.

[0030] In use, place the wood-plastic composite (WPC) board to be spliced ​​on one side of the spliced ​​WPC board, with the second vent 7 facing downwards. Place the connecting plate 12 into the mounting groove 9 at one end of the anti-slip groove 8, connecting the WPC board to be spliced ​​and the spliced ​​WPC board. If the temperature is too high, the heat from the WPC board body 1 will be quickly transferred to the heat dissipation cavity 2 through the aluminum plate 4. The first vent 6 and the second vent 7 on the support plate 5 will dissipate the local heat, preventing localized high temperatures in the WPC board and improving its high-temperature resistance. The above operation enables the use of the WPC board.
