▎ 摘　　要

NOVELTY - Graphene-damping material comprises aqueous acrylate, aqueous polyurethane, polysiloxane, hollow fiber, layer-by-layer self-assembly processing rare earth oxide hollow micro-ball, graphene foam and bentonite. USE - Used as graphene-damping material. ADVANTAGE - The material has double sound absorption mechanism of cavity sound absorption structure and viscoelastic damping property, achieves muffler, uses traditional asphalt damping plate and is environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene-damping material comprising uniformly mixing aqueous acrylate, aqueous polyurethane, polysiloxane, hollow fiber, layer-by-layer self-assembly processing rare earth oxide hollow micro-ball, graphene foam and bentonite.
