[0002] Insulation board is a board used for insulation of buildings. It is made of polystyrene resin as raw material, other raw materials and polymers, which are heated and mixed, and then injected with catalysts, and then extruded and pressed to form a rigid foam plastic board. It has moisture-proof and waterproof properties, and can reduce the thickness of the building's external protective structure, thereby increasing the indoor usable area.

[0003] Chinese patent CN212802035U discloses a rigid foam polyurethane porous cotton composite insulation board, which can improve the impermeability and corrosion resistance of the insulation board through the first cement glass fiber layer and the second cement glass fiber layer, and can improve the thermal insulation and heat insulation effects of the insulation board through the first thermal insulation layer and the second thermal insulation layer, and can improve the combustion level of the insulation board through the first flame retardant layer and the second flame retardant layer, thereby improving the fire resistance of the insulation board.

[0004] However, most of the existing insulation boards are square. When installing the insulation boards, the insulation boards need to be spliced ​​together. When installing the insulation boards, workers need to minimize the gap between the two insulation boards. Most of the existing insulation boards have simple structures, and workers cannot quickly splice the insulation boards, which prolongs the construction period. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a fire-resistant and flame-retardant polyurethane composite insulation board, which solves the problem that workers cannot quickly splice the insulation boards during installation, thereby prolonging the construction period.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a fire-proof and flame-retardant polyurethane composite insulation board, comprising an insulation board body, a mounting block is fixedly provided on the adjacent edge of one side of the insulation board body, a mounting groove matching the mounting block is fixedly provided on the adjacent edge of the other side of the insulation board body, the mounting block is filled with a flame retardant, a wall connecting plate is fixedly provided on one surface of the insulation board body, an insulation layer is fixedly provided on the other surface of the insulation board body, a flame retardant layer is fixedly provided on the insulation layer, and a protective layer is fixedly provided on the flame retardant layer.

[0007] Preferably, a moisture-proof layer is provided on the wall connecting plate, and the moisture-proof layer is filled with activated carbon.

[0008] Preferably, a honeycomb frame is provided inside the thermal insulation layer, and glass fibers are fixed in the gaps of the honeycomb frame.

[0009] Preferably, a lime wool interlayer is fixedly provided between the thermal insulation layer and the flame retardant layer, the lime wool interlayer is filled with graphite wool fibers and gypsum, and the thickness of the lime wool interlayer is 0.1 mm.

[0010] Preferably, the protective layer is aluminum alloy protection.

[0011] Preferably, the thickness of the honeycomb skeleton is 1 mm.

[0012] Beneficial Effects

[0013] The utility model provides a fire-proof and flame-retardant polyurethane composite insulation board. Compared with the prior art, it has the following beneficial effects:

[0014] (1) The fireproof and flame-retardant polyurethane composite insulation board can be quickly assembled by matching the installation block on the insulation board body with the installation groove, thereby reducing the workload during installation, shortening the construction period, and improving the installation efficiency. The flame retardant in the installation block can block the fire in the event of a fire, thereby improving its safety.

[0015] (2) The fireproof and flame-retardant polyurethane composite insulation board uses a honeycomb skeleton inside the insulation layer to improve the strength of the insulation board body and cooperate with the protective layer to increase its service life. The lime wool interlayer increases the heat insulation, fire resistance and sound insulation of the insulation board body. The activated carbon in the moisture-proof layer absorbs the moisture generated when the wall is damp, thereby reducing the impact of moisture on the insulation board body and thus increasing its service life.
