The utility model patent with the publication number of CN213798436U entitled "dampproof antibacterial aluminum foil composite material", discloses a dampproof antibacterial aluminum foil composite material, which comprises a foil body, wherein an aluminum material reinforcing layer is arranged at the middle position inside the foil body, a first antibacterial layer is arranged at the upper end of the aluminum material reinforcing layer, a first heat-resistant layer is arranged at the upper end of the first antibacterial layer, a first hydrophobic coating is arranged at the upper end of the first heat-resistant layer, a second antibacterial layer is arranged at the lower end of the aluminum material reinforcing layer, a second heat-resistant layer is arranged at the lower end of the second antibacterial layer, and a second hydrophobic coating is arranged at the lower end of the second heat-resistant layer. According to the utility model, the first antibacterial layer and the second antibacterial layer are antibacterial plates with antibacterial agents arranged therein, so that corrosion of bacteria can be reduced, the bacteria can be removed by the antibacterial agents in the first antibacterial layer and the second antibacterial layer when the bacteria pass through the first antibacterial layer and the second antibacterial layer, the overall strength of the foil body can be increased by the arranged aluminum reinforcing layer, the foil body has certain compression resistance, and the multilayer structure can be tightly connected and fixed by the arranged adhesive layer. However, the overall structure is relatively complex, and there is no advantage in keeping the light weight and the high strength, and especially there is a disadvantage in the acoustic field in terms of half-empty sound insulation.
