[0002] Indoor wall panels mostly adopt a composite material structure, that is, metal plates are composited with functional materials to obtain wall panels with specified functional effects, and then multiple such wall panels are assembled and spliced ​​to meet usage requirements. For example, the high-airtightness clean room wall panels disclosed in the patent document with application number CN202321033201.2 include a melamine resin surface layer in contact with indoor air, one side of the melamine resin surface layer is fixedly connected to a color steel plate surface layer, and the outer surface of the melamine resin surface layer is sequentially provided with a protective plate, a first resin coating, an activated carbon layer, and a second resin coating. By setting the wall panel to be fixedly connected by a melamine resin surface layer and a color steel plate surface layer, it can have the effects of rust prevention and impact resistance, as well as waterproof and breathable effects. The galvanized steel plate protective plate, PET first resin coating, activated carbon layer, and PET second resin coating coated on the surface of the melamine resin surface layer in sequence can make the wall panel resistant to high temperature, resistant to burning and cracking, and not easy to damage, which greatly increases the service life of the wall panel. At the same time, the activated carbon layer added to the surface of the melamine resin surface layer can purify the indoor air and optimize the environment when the wall panel is used in a clean room. Correspondingly, the wall panel can obtain a sound insulation effect by compounding the sound insulation material with the metal plate, but the structure formed by the sound insulation material used in the existing wall panel is usually a single-layer structure, and the sound insulation and silencing effect has gradually failed to meet the requirements.
