Sound absorption brick based on perlite loaded graphene and preparation method of sound absorption brick
The invention belongs to the field of sound absorption materials for buildings, and relates to a sound absorption brick based on perlite loaded graphene and a preparation method of the sound absorption brick. The sound absorption brick based on perlite-loaded graphene is mainly prepared from the following raw materials in parts by weight: 30-50 parts of a perlite-loaded graphene composite porous material, and 50-70 parts of an adhesive. According to the sound absorption brick based on perlite loaded graphene, perlite is a porous material of a macroporous structure, multiple layers of graphene are synthesized on the surface of perlite through a chemical vapor deposition method, a composite porous material of a porous structure with the adjustable multi-scale gradient is constructed, the composite porous material and the adhesive are compounded to prepare the sound absorption brick, the porosity can be effectively improved, and the specific surface area of the perlite is enabled to be larger. By combining the unique surface characteristics of graphene, the sound absorption effect is remarkably improved, and the sound absorption material is widely applied to the field of building sound absorption materials and effectively improves the space absorption effect.
