Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb panels, in particular to an environmentally friendly high-strength PP honeycomb panel. Background Art

[0002] At present, China Patent No.: CN201520911723.7 discloses a PP honeycomb board, including a board, one side of the board is provided with a longitudinal projection, and the other side of the board is provided with a longitudinal groove used in conjunction with the longitudinal projection, the front end of the board is provided with a transverse groove, the rear end of the board is provided with a transverse projection used in conjunction with the transverse groove, and the inside of the board is provided with a belly cloth, a polyurethane layer, a melamine layer, a PP honeycomb layer and an XPS thermal insulation layer from top to bottom, the polyurethane layer and the melamine layer are connected by a PP keel, and the melamine layer and the XPS thermal insulation layer are connected to the PP honeycomb layer by a PEEK skeleton. The PP honeycomb board uses PP keels and PEEK skeletons to connect the layers, making the structure more compact, enhancing its strength under transverse or longitudinal pressure, and making it less likely to deform. The provided projections and grooves make the installation and use of the board more convenient, simple and convenient to use, and save installation time. However, in actual use, the prior art still has the problem that the strength of the honeycomb panel made of PP material is much weaker than the honeycomb panel made of metal material on the front and back sides, and there are certain limitations in use. Utility Model Content

[0003] Therefore, in view of the above problems, the utility model proposes an environmentally friendly high-strength PP honeycomb panel, which solves the technical problem that the strength of the honeycomb panel made of PP material is much less than that of the honeycomb panel made of metal material on the front and back sides in the prior art, and there are certain limitations in use.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an environmentally friendly high-strength PP honeycomb panel, whose structure includes a top plate, a top plate reinforcement layer, a honeycomb panel, a bottom plate, a bottom plate reinforcement layer, and a heat insulation layer. The top plate reinforcement layer is arranged at the bottom of the top plate, the top plate reinforcement layer is fixedly connected to the honeycomb panel, the lower part of the honeycomb panel is fixedly connected to the bottom plate, the bottom plate reinforcement layer is arranged on the lower side of the bottom plate, and the heat insulation layer is arranged at the bottom of the bottom plate reinforcement layer. The top plate reinforcement layer and the bottom plate reinforcement layer have the same structure, and both of them have transverse and longitudinal reinforcement fiber belts cross-arranged.

[0005] Furthermore, the top plate reinforcement layer is fixed to the top plate by bonding or is directly arranged at a lower position inside the top plate.

[0006] Furthermore, the honeycomb panel is fixedly connected to the bottom plate and the top plate by bonding.

[0007] Furthermore, the bottom plate reinforcement layer is fixedly connected to the bottom plate by bonding, or is directly arranged at a lower position inside the bottom plate.

[0008] Furthermore, the heat insulation layer is made of polyurethane with a thickness of 5-10 mm.

[0009] Furthermore, the reinforcing fiber belt is made of glass fiber or carbon fiber.

[0010] By adopting the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: the environmentally friendly high-strength PP honeycomb panel improves the existing technology. In actual use, the strength of the honeycomb panel made of PP material is much less than that of the honeycomb panel made of metal material on the front and back, and there are certain limitations in use. By adding reinforcing fiber bands cross-arranged by transverse and longitudinal fiber bands, the strength of the scheme can be effectively increased, and the tensile and bending strength can be increased by a maximum of 20% without much increase in the self-weight, which can effectively improve the scope of application of the scheme. Compared with the scheme using metal plates, the weight is lighter. With the current decline in carbon fiber costs, the cost of this scheme is also continuously declining, and there is a greater profit margin. BRIEF DESCRIPTION OF THE DRAWINGS
