Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC wood-plastic composite board technology, and in particular to a high-temperature resistant and heat-resistant PVC wood-plastic composite board. Background Technology
[0002] PVC wood-plastic composite board is a new type of environmentally friendly board made of PVC material and wood powder. It ensures the board's resistance to moisture, corrosion and deformation, and is widely used in wall decoration and flooring.
[0003] Due to the limitations of PVC materials, the heat resistance temperature range of ordinary PVC wood-plastic composite boards is between 60℃ and 80℃. They are prone to deformation when in contact with objects with a surface temperature exceeding 80℃, have poor heat resistance, and are easily left with burn marks when exposed to high-temperature objects, which are difficult to repair. Improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a high-temperature resistant and heat-resistant PVC wood-plastic board that improves the surface's high-temperature resistance and avoids the problem of leaving burn marks when in contact with high-temperature objects.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A high-temperature resistant and heat-resistant PVC wood-plastic composite board includes: a PVC wood-plastic composite board substrate, heat-conducting columns, a first heat-equalizing mesh, a second heat-equalizing mesh, a high-temperature resistant protective layer, and a heat dissipation reinforcing layer. The first heat-equalizing mesh is disposed on the top surface of the PVC wood-plastic composite board substrate, and a first heat-conducting adhesive layer is disposed on the first heat-equalizing mesh. The high-temperature resistant protective layer is disposed on the top surface of the first heat-conducting adhesive layer. The second heat-equalizing mesh is disposed on the bottom surface of the PVC wood-plastic composite board substrate, and a second heat-conducting adhesive layer is disposed on the second heat-equalizing mesh. The heat dissipation reinforcing layer is disposed on the bottom surface of the second heat-conducting adhesive layer. The heat-conducting columns are spaced apart in the PVC wood-plastic composite board substrate and connected between the first heat-equalizing mesh and the second heat-equalizing mesh.
[0007] The first thermally conductive adhesive layer and the second thermally conductive adhesive layer are respectively made of thermally conductive adhesive.
[0008] The first and second heat-regulating nets are made of steel wire mesh.
[0009] The heat-conducting columns are made of steel, and their two ends are welded and fixed to the corresponding first and second heat-equalizing meshes, respectively.
[0010] The PVC wood-plastic composite board substrate is provided with an array of through holes corresponding to the heat-conducting columns.
[0011] The high-temperature resistant protective layer is made of polytetrafluoroethylene coating.
[0012] The heat dissipation enhancement layer is made of aluminum sheet.
[0013] The beneficial effects of this utility model are as follows: A high-temperature resistant and heat-resistant PVC wood-plastic composite board, with a high-temperature resistant protective layer for top surface protection, improves the high-temperature resistance. When the high-temperature resistant protective layer comes into contact with a high-temperature object (not exceeding 200°C), it can transfer heat to the first heat-equalizing mesh, and then transfer the heat to the second heat-equalizing mesh using heat-conducting columns, thus diffusing the heat horizontally and dissipating it through the heat dissipation reinforcement layer. This avoids the accumulation of heat in the PVC wood-plastic composite board substrate, and prevents the deformation of the PVC wood-plastic composite board substrate and the problem of leaving burn marks on the surface of the high-temperature resistant protective layer. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of this utility model;
[0015] Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation
[0016] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.
[0017] like Figure 1 and Figure 2 The high-temperature resistant and heat-resistant PVC wood-plastic composite board shown includes: a PVC wood-plastic composite board substrate 1, a heat-conducting column 2, a first heat-equalizing mesh 5, a second heat-equalizing mesh 6, a high-temperature resistant protective layer 3, and a heat dissipation reinforcing layer 4. The first heat-equalizing mesh 5 is disposed on the top surface of the PVC wood-plastic composite board substrate 1. A first thermally conductive adhesive layer 8 is disposed on the first heat-equalizing mesh 5. The first heat-equalizing mesh 5 is fixed on the top surface of the PVC wood-plastic composite board substrate 1 through the first thermally conductive adhesive layer 8, and the flatness of the first heat-equalizing mesh 5 is ensured.
[0018] The high-temperature resistant protective layer 3 is disposed on the top surface of the first thermally conductive adhesive layer 8. In this embodiment, the high-temperature resistant protective layer 3 is made of polytetrafluoroethylene coating, which has a high temperature resistance of far exceeding 200°C. It protects the top surface of the PVC wood-plastic composite substrate 1 and improves the high-temperature resistance. When the high-temperature resistant protective layer 3 comes into contact with a high-temperature object (not exceeding 200°C), it can transfer heat to the first heat-equalizing net 5. The heat is diffused horizontally through the first heat-equalizing net 5, avoiding concentration in a local area of the PVC wood-plastic composite substrate 1.
[0019] The second heat-equalizing mesh 6 is placed on the bottom surface of the PVC wood-plastic composite board substrate 1. A second thermally conductive adhesive layer 7 is provided on the second heat-equalizing mesh 6. The heat dissipation strengthening layer 4 is placed on the bottom surface of the second thermally conductive adhesive layer 7. The second thermally conductive adhesive layer 7 can both fix the second heat-equalizing mesh 6 on the bottom surface of the PVC wood-plastic composite board substrate 1 and fix the heat dissipation strengthening layer 4.
[0020] In this embodiment, the first thermally conductive adhesive layer 8 and the second thermally conductive adhesive layer 7 are respectively made of thermally conductive adhesive that can withstand temperatures above 200°C, thus avoiding the problem of detachment due to heat. The heat dissipation reinforcement layer 4 is made of aluminum sheet, which has good heat dissipation performance and can diffuse and dissipate heat horizontally.
[0021] The heat-conducting columns 2 are spaced apart in the PVC wood-plastic composite board substrate 1 and connected between the first heat-equalizing net 5 and the second heat-equalizing net 6. In this embodiment, the PVC wood-plastic composite board substrate 1 is provided with an array of through holes corresponding to the heat-conducting columns 2, which facilitates assembly.
[0022] like Figure 2 As shown, the heat-conducting columns 2 are made of steel, and the first heat-equalizing mesh 5 and the second heat-equalizing mesh 6 are made of steel wire mesh. The two ends of the heat-conducting columns 2 are welded and fixed to the corresponding first heat-equalizing mesh 5 and second heat-equalizing mesh 6, which further improves the overall structural stability, prevents the first heat-equalizing mesh 5 and the second heat-equalizing mesh 6 from separating, and uses the heat-conducting columns 2 to vertically transfer the heat of the first heat-equalizing mesh 5 to the second heat-equalizing mesh 6, and uses the second heat-equalizing mesh 6 to diffuse it in the horizontal direction, so as to avoid the heat accumulation in the PVC wood-plastic composite board substrate 1 and avoid the heat deformation of the top surface (working surface) of the PVC wood-plastic composite board substrate 1.
[0023] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
