Technical Field

[0001] The utility model relates to the technical field of home building materials, in particular to a multifunctional flame retardant board. Background Art

[0002] The existing flame retardant boards have certain technical defects: the flame retardant performance of the existing insulation boards is not very ideal. When the insulation boards are burned, they will be easily damaged, the service life of the insulation boards will be affected, and their own quality cannot be guaranteed. In addition, when the insulation boards are piled up and stored in the company's warehouse, the hidden danger of open flames cannot be avoided, and production safety cannot be guaranteed.

[0003] As people have higher and higher requirements for house building materials and interior decoration, they require that building insulation boards should not only meet the requirements of flame retardancy, but also solve other problems caused by civil engineering structures, such as the poor insulation effect caused by the thin wall surface; water seepage in the wall after the wall is too thick, etc. In addition, the requirements for other properties of flame retardant boards are also getting higher and higher. In order to improve the application scope of flame retardant boards, some flame retardant boards are added with composite materials during the processing process to increase functions, such as flame retardant boards with multifunctional waterproof or thermal insulation effects. However, when the existing multifunctional flame retardant boards add other functions, they may destroy the original properties of the flame retardant boards, such as flame retardancy, strength, etc., which affects the popularization and application of flame retardant boards. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional flame retardant board, which not only has flame retardant effect, but also has waterproof and heat preservation effects, and is provided with three flame retardant layers, so that the flame retardant effect is better and the board also has good strength.

[0005] Based on the above purpose, the present invention adopts the following technical solutions:

[0006] A multifunctional flame retardant panel comprises a substrate, a heat insulating layer is provided above the substrate, a first flame retardant layer is provided above the heat insulating layer, a waterproof layer is provided above the first flame retardant layer, a thermal insulation layer is provided above the waterproof layer, an exterior wall panel is provided above the thermal insulation layer, a second flame retardant layer is provided inside the exterior wall panel; the second flame retardant layer is a cavity opened inside the exterior wall panel, the cavity is filled with a flame retardant filler; a plurality of through holes penetrating the exterior wall panel are evenly arranged at the upper and lower parts of the cavity, reinforcing ribs matching the through holes are provided inside the through holes, and a third flame retardant layer is also provided outside the exterior wall panel.

[0007] Preferably, the first flame retardant layer is a flame retardant foam board.

[0008] Preferably, the flame retardant filler is fine sand.

[0009] Preferably, the third flame retardant layer is a flame retardant coating.

[0010] Preferably, the thermal insulation layer is flame retardant polyurethane foam.

[0011] Preferably, the end face of the through hole is circular or polygonal, and the rib is cylindrical or polygonal to match it.

[0012] Preferably, the second flame retardant layer includes four cavities opened in the exterior wall panel, and the four cavities are evenly distributed in the exterior wall panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the multifunctional flame retardant board provided by the utility model has better flame retardant effect by setting three flame retardant layers, and also has good waterproof performance and heat preservation performance. Furthermore, by setting ribs, the strength and mechanical properties of the flame retardant board are further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS
