NOVELTY - High temperature high power density graphene heating coating comprises 15-30 pts. wt. conductive graphene, 6-14 pts. wt. conductive metal powder, 30-50 pts. wt. film-forming resin, 2-7 pts. wt. dispersant, 15-25 pts. wt. solvent and 1-4 pts. wt. assistant. USE - High temperature high power density graphene heating coating. ADVANTAGE - The high temperature high power density graphene heating coating has good adhesive force, high hardness, high temperature resistance, temperature variation resistance, moist heat resistance, boiling resistance, mildew resistance, fast and safe heat production, and increases power density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is incldued for a method for preparing a high-temperature high-power density graphene heating coating, which involves: (A) adding a solvent and a dispersant in the container A, stirring, adding conductive graphene to disperse until the system is uniform to obtain a slurry; (B) adding the film-forming resin and solvent in the container B, stirring, adding the auxiliary agent, dispersing until the system is uniform to obtain the base material; (C) adding slurry to the base material under stirring, dispersing until the system is uniform, adding conductive metal powder, and dispersing again until the system is uniform to obtain a liquid coating of graphene heating coating; and (D) applying liquid coating of the graphene heating coating on the target substrate by spraying or brushing, etc, and curing at room temperature or accelerating curing after baking to obtain high temperature resistant high power density graphene heating coating on floor.
