▎ 摘　　要

NOVELTY - A graphene-based fire-proof plastic plate comprises laminated graphene fireproof layer and plastic substrate layer. The graphene fireproof layer comprises intrinsic graphene. USE - Graphene-based fire-proof plastic plate. ADVANTAGE - The plate is not easy to fall off after plastic substrate layer is deformed by heat, has low density and excellent barrier property and hydrophobic property, protects plastic substrate at misfire condition, delays plastic substrate layer burning and release time of poisonous gas, keeps good adhesion to plastic substrates, increases strength of expanded carbon layer, and improves flame retardant effect, heat insulation effect, stretch-proof property, flexibility, water resistance and service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene-based fire-proof plastic plate comprising surface treating plastic substrate material layer to obtain pre-treated plastic substrate material layer, coating on surface of graphene fireproof coating, and forming graphene layer.
