[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, this utility model provides a composite foam board, including a foam main body layer 11. An insulation layer 12 is provided on one side of the foam main body layer 11. The insulation layer 12 includes a substrate 121 and a core 122. The insulation layer 12 improves the thermal insulation performance of the foam board. The core 122 is located within the substrate 121, and a barrier membrane 123 is provided between the core 122 and the substrate 121. The barrier membrane 123 prevents leakage of substances inside the core 122 while ensuring gas exchange. A heat insulation layer 13 is provided on the other side, and an aluminum foil reflective film 14 is provided between the heat insulation layer 13 and the insulation layer 12. The aluminum foil reflective film 14 reflects heat, enhances the heat insulation effect, and reduces heat transfer between the insulation layer 12 and the heat insulation layer 13. An adsorption layer 15 and a catalytic layer 16 are sequentially arranged on the side of the insulation layer 12 away from the main foam layer 11. The adsorption layer 15 and catalytic layer 16 adsorb and catalytically decompose harmful gases in the air, improving air quality. The adsorption layer 15 has multiple sets of through holes 151, filled with adsorbent 152. This increases the contact area between the adsorbent 152 and the air, improving the adsorption efficiency of harmful gases. The catalytic layer 16 has channels 161, the inner walls of which are coated with a catalyst coating 162. This allows the catalyst to fully contact the passing gas, catalytically decomposing harmful gases. A protective layer 17 is provided on the side of the catalytic layer 16 away from the adsorption layer 15. The protective layer 17 protects the catalytic layer 16 from damage by external factors while ensuring air circulation.

[0024] like Figure 2 , 4As shown, the substrate 121 is made of polyester fiber, the core 122 is made of aerogel composite material, the core 122 has a honeycomb reinforcing structure 124, and the barrier membrane 123 is an aluminum-plastic composite membrane. By using the substrate 121, which is formed by hot pressing recycled polyester fiber and waste rubber particles, resource recycling can be achieved, costs can be reduced, and a certain degree of thermal insulation and structural support can be provided. By using aerogel composite material as the core 122, the low thermal conductivity can be utilized to improve thermal insulation performance. The honeycomb reinforcing structure 124 on the core 122 can enhance the strength and stability of the core 122. By using the aluminum-plastic composite membrane as the barrier membrane 123, the barrier properties of aluminum and the flexibility of plastic can be combined to prevent material leakage and maintain structural stability.

[0025] The insulation layer 13 comprises a perlite insulating mortar layer 131 and a PET foam layer 132 (polyethylene terephthalate foam layer), which are connected by a sawtooth interface 133. The arrangement of the perlite insulating mortar layer 131 and the PET foam layer 132 to form the insulation layer 13 allows both layers to utilize their insulating properties and block heat transfer. The sawtooth interface 133 increases the contact area between the two layers, enhances connection stability, and further improves the insulation effect.

[0026] like Figure 2 , 3 As shown, the aluminum foil reflective film 14 has a rolled corrugated structure with continuous V-shaped corrugations. By using the rolled corrugated structure and the continuous V-shaped corrugations, the surface area of ​​the aluminum foil reflective film 14 can be increased, enhancing its ability to reflect heat radiation and improving the overall structural strength of the foam board.

[0027] like Figure 2 , 4 As shown, the adsorption layer 15 is a polyurethane foam layer, the inner wall of the through-hole 151 is provided with a polydopamine adhesive layer 153, and the adsorbent 152 is nano-zinc oxide particles. The polyurethane foam layer as the adsorption layer 15 provides a porous structure, facilitating gas flow and adsorption; the polydopamine adhesive layer 153 on the inner wall of the through-hole 151 fixes the nano-zinc oxide particles, preventing them from falling off; and the use of nano-zinc oxide particles as the adsorbent 152 utilizes their high specific surface area and adsorption activity to adsorb harmful gases.

[0028] The catalyst layer 16 is a porous ceramic fiber layer, and the catalyst coating 162 is a manganese iron oxide composite. Using a porous ceramic fiber layer as the catalyst layer 16 provides a large specific surface area, allowing for sufficient contact between the gas and the catalyst; using manganese iron oxide as the catalyst coating 162 catalytically decomposes harmful gases.

[0029] The protective layer 17 is a polytetrafluoroethylene (PTFE) microporous membrane, with multiple sets of vent holes 171 evenly distributed on it. By using the PTFE microporous membrane as the protective layer 17, its chemical stability and water resistance protect the catalyst layer 16 from external corrosion. The vent holes 171 on the protective layer 17 ensure smooth airflow, allowing harmful gases to enter the catalyst layer 16 for reaction.

[0030] The specific usage and function of this embodiment are as follows:

[0031] During construction, the modular foam board is installed on walls, roofs, and other structures, with the main foam layer 11 serving as the foundation support structure. In the insulation layer 12, the matrix 121 and core 122 work together; the aerogel composite core 122, combined with the honeycomb reinforcement structure 124, provides insulation, while the barrier membrane 123 prevents internal material leakage. In the heat insulation layer 13, the perlite insulating mortar layer 131 and the PET foam layer 132 are connected by a sawtooth interface 133, blocking heat transfer, and the aluminum foil reflective film 14 further reflects heat. In the indoor environment, the nano-zinc oxide particles 152 of the adsorption layer 15 adsorb harmful gases such as formaldehyde through the pores 151, and the polydopamine adhesive layer 153 ensures the stability of the adsorbent. Subsequently, the gas enters the catalytic layer 16, where manganese iron oxide catalytically decomposes the harmful gases on the inner walls of the porous ceramic fiber layer's pores 161. The protective layer 17 has a polytetrafluoroethylene microporous membrane that protects the catalytic layer 16, and the vents 171 ensure air circulation, ultimately achieving the dual function of improving the building's thermal insulation performance and purifying indoor air.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
