▎ 摘　　要

NOVELTY - Graphite radiating copper foil paint comprises 5-30 pts. wt. graphene slurry, 25-70 pts. wt. boron slurry, 5-10 pts. wt. bonding agent and 1-60 pts. wt. diluent. The graphene slurry comprises 5-50 pts. wt. graphene powder, 1-10 pts. wt. surface treating agent and 40-94 pts. wt. solvent. The boron nitride slurry comprises 10-30 pts. wt. boron nitride powder, 1-10 pts. wt. surface processing agent and 60-89 pts. wt. solvent. USE - Graphite radiating copper foil paint. ADVANTAGE - The graphite radiating copper foil paint has improved radiating and insulating performance. DETAILED DESCRIPTION - Graphite radiating copper foil paint comprises 5-30 pts. wt. graphene slurry, 25-70 pts. wt. boron slurry, 5-10 pts. wt. bonding agent and 1-60 pts. wt. diluent. The graphene slurry comprises 5-50 pts. wt. graphene powder, 1-10 pts. wt. surface treating agent and 40-94 pts. wt. solvent. The boron nitride slurry comprises 10-30 pts. wt. boron nitride powder, 1-10 pts. wt. surface processing agent and 60-89 pts. wt. solvent. The surface treatment agent includes one or more amides and polyethers. The solvent is propylene glycol methyl ether acetate, methyl nylon acetate, toluene and butyl acrylate. The binder is an acrylic resin, epoxy resin or a silicone resin. The diluent is one or more of ethylene glycol, ethylene glycol butyl ether acetate or butyl acetate or propylene glycol methyl ether acetate. An INDEPENDENT CLAIM is included for a method for preparing graphite radiating copper foil paint, which involves: (A) mixing 1-60 pts. wt. diluent, 1-10 pts. wt. surface treatment agent and 30-80 pts. wt. graphite alkene powder; (B) stirring the mixture; (C) carrying out sand grinding or ball milling to obtain graphene slurry; (D) adding 1-60 pts. wt. diluent, 1-10 pts. wt. surface processing agent and 20-70 pts. wt. boron nitride; (E) stirring the obtained mixture; (F) carrying out sand grinding or ball milling to obtain the boron nitride slurry; (G) mixing and stirring graphene slurry and boron slurry; and (H) adding bonding agent.
