NOVELTY - Graphene composite material with excellent heat conducting performance comprises 30-50 pts. wt. epoxy resin, 10-15 pts. wt. coupling agent, 3-5 pts. wt. dimethyl silicone oil, 1-5 pts. wt. graphene nanosheets, 20-30 pts. wt. resin solvent, 10-30 pts. wt. curing agent, and 30-50 pts. wt. solvent. USE - Graphene composite material with excellent heat conducting performance. ADVANTAGE - The graphene composite material has thermal conductivity i.e. 0.58 Watt/(m.Kelvin) at 40 degrees C, reduces the production cost, and improves heat-conducting performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene composite material with excellent heat conducting performance, which involves: (A) taking ingredients to prepare mixture; (B) adding mixture nto the molding die, and then placing molding die in a magnetic field for pre-curing treatment, adjusting direction of the mold to ensure that the thermal conductivity of the composite after the molding is strengthened is consistent with the direction of the magnetic field; and (C) drying forming mold in a drying box, after the drying is completed, taking solidified mixture from forming mold to obtain graphene composite material.
