▎ 摘　　要

NOVELTY - Preparing conductive intumescent flame retardant coating using composite graphene comprises adding dispersant sodium silicate octahydrate into quantitive water, stirring for the first time to obtain the pre-formed dispersant solution, adding polyester resin, pentaerythritol, urea and ammonium polyphosphate into pre-dispersing solution, stirring for the second time to obtain an intumescent flame retardant coating, adding the spherical graphite/graphene composite powder and dimethicone sequentially into the intumescent flame retardant coating and stirring for the third time. USE - The composite graphene is useful for preparing conductive intumescent flame retardant coating (claimed). ADVANTAGE - The composite graphene is environment-friendly, economical and has good conductivity.
