▎ 摘　　要

NOVELTY - A graphene-modified building exterior wall thermal insulation coating comprises a base material comprising film-forming material, additives, solvent and graphene. The amount of graphene is 1-10 wt.% of the base material. USE - Graphene-modified building exterior wall thermal insulation coating (claimed). ADVANTAGE - The graphene-modified building exterior wall thermal insulation coating ensures high mechanical strength and improved stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene-modified building exterior wall thermal insulation coating, which involves using film-forming material as base material, adding graphene powder, stirring evenly, adding additives and solvent, stirring, centrifuging and drying, adding the dried raw material to the base material, stirring and leaving the mixture still.
