[0024] This utility model provides an improved, high-efficiency fireproof and heat-insulating exterior wall insulation board. The technical solution of this utility model is as follows:

[0025] In embodiments of this utility model, such as Figures 1-3 As shown, a high-efficiency fireproof and heat-insulating exterior wall insulation board includes a frame layer 1, with fireproof and heat-insulating outer layers 2 fixed on both sides of the frame layer 1. The fireproof and heat-insulating outer layers 2 on both sides of the frame layer 1 can achieve a double fireproof and heat-insulating protection effect for the insulation board. The fireproof and heat-insulating outer layers 2 include a ceramicized silicone rubber fireproof layer and a modified aerogel felt arranged sequentially from the outside to the inside. A flame-retardant polyurethane foam layer is filled between the inner side of the fireproof and heat-insulating outer layer 2 and the frame layer 1. The ceramicized silicone rubber fireproof layer can be ceramicized at high temperature to form a dense carbonized layer, which isolates oxygen for fireproofing. The modified aerogel felt is made by combining silica aerogel with basalt fiber. The structure effectively reduces thermal conductivity to achieve thermal insulation. Multiple spaced and interconnected medium-sized cavities 5 are formed within the skeleton layer 1. Sound-absorbing columns 8 are installed at the connection points between adjacent medium-sized cavities 5. Symmetrically distributed sound-absorbing panels 6 are installed within the medium-sized cavities 5. Serrated surfaces 7 are formed on the adjacent sidewalls of two sound-absorbing panels 6. The medium-sized cavities 5 reduce heat conduction efficiency, further enhancing the thermal insulation effect. Additionally, the symmetrically arranged sound-absorbing panels 6 within the medium-sized cavities 5 buffer and reduce noise, while the serrated surfaces 7 refract and guide noise, increasing the travel distance of sound waves within the medium-sized cavities 5 and further improving the noise reduction effect.

[0026] In an embodiment of this utility model, a protruding connecting part 3 is provided on one side of the skeleton layer 1, and a recessed snap-fit ​​part 4 is provided on the other side of the skeleton layer 1 to fit the connecting part 3. The connecting part 3 and the snap-fit ​​part 4 facilitate the splicing and installation of multiple insulation boards. The connecting part 3 includes a protruding edge 31 connected to the skeleton layer 1, and the snap-fit ​​part 4 includes a slot 41 on the side of the skeleton layer 1 that fits the protruding edge 31. The protruding edge 31 can slide into the slot 41 to achieve the purpose of assembling the insulation boards. Dovetail grooves 32 are provided on both sides of the protruding edge 31, and an arc groove 33 is provided on the end face of the protruding edge 31. The inner sidewall of the slot 41 is provided with a dovetail strip 42 and an arc protrusion 43 that slide and snap with the dovetail groove 32 and the arc groove 33. The locking fit between the dovetail groove 32 and the dovetail strip 42, and between the arc groove 33 and the arc protrusion 43, increases the connection strength between the protruding edge 31 and the slot 41 and prevents them from separating.

[0027] The working principle of the high-efficiency fireproof and heat-insulating exterior wall insulation board provided by this utility model is as follows: The fireproof and heat-insulating outer layers 2 on both sides of the skeleton layer 1 can achieve the double fireproof and heat-insulating protection effect of the insulation board. The ceramicized silicone rubber fireproof layer can be ceramicized at high temperature to form a dense carbonized layer, which isolates oxygen for fireproofing. The modified aerogel felt is composed of silica aerogel and basalt fiber composite, which effectively reduces the thermal conductivity to achieve the purpose of heat insulation. The medium cavity 5 can reduce the heat conduction efficiency and further increase the heat insulation effect. In addition, the sound-absorbing plates 6 symmetrically arranged in the medium cavity 5 can buffer and reduce noise. The serrated surface 7 can refract and guide the noise, increasing the movement of sound waves in the medium cavity 5. The convex edge 31 can be slidably inserted into the slot 41 to achieve the assembly purpose between the insulation boards. The locking cooperation between the dovetail groove 32 and the dovetail strip 42, and the arc groove 33 and the arc convex strip 43 increases the connection strength between the convex edge 31 and the slot 41 and prevents them from separating.
