▎ 摘　　要

NOVELTY - A perlite-loaded graphene sound absorbing brick comprises 30-50 pts. wt. perlite loaded graphene composite porous material and 50-70 pts. wt. adhesive. USE - The perlite-loaded graphene sound absorbing brick is used for building sound absorbing material field. ADVANTAGE - The brick has multi-scale gradient adjustable hole structure, improved porosity, large specific surface area, and improved sound absorbing effect and improves space absorbing effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the sound absorbing brick comprising mixed perlite loaded graphene composite porous material and adhesive, placing in mold, and demolding.
