▎ 摘　　要

NOVELTY - Manufacturing graphene heat-dissipating film coil, comprises taking the graphene oxide cake material and dispersing in deionized water to obtain a graphene oxide dispersion liquid, obtaining aqueous ammonia, slowly pouring into the graphene oxide dispersion liquid, performing homogenization and defoaming treatment to obtain a graphene oxide slurry, taking a substrate, coating graphene oxide slurry on substrate by a coating machine, peeling and slitting, controlling winding tension to form a tight pretreated graphene film tight coil, placing pretreated graphene film tight coil in a rewinding mechanism for unwinding, obtaining the pretreated graphene film loose coil with preset tightness, placing the pretreated graphene film loose coil for low temperature treatment, carrying out carbonization, and graphitizing to obtain graphene foam film roll, subjecting the graphene foam film roll material to single-layer rolling or multi-layer rolling under the action of the squeeze roller. USE - Method for manufacturing graphene heat-dissipating film coil. ADVANTAGE - The graphene of radiating film coiled material has good stability, and improves the production efficiency and reduces the cost. The manufacturing technique of the graphene can prepare continuous dispersed and stable graphene. The graphene is capable of only preparation graphene sheet, resulting in subsequent die cutting cost is too high, the production process is fussy, the labor cost is high, it cannot meet the industrial automaton production requirement and so on, it provides a new manufacturing graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of the pretreated graphene film loose coil material in manufacturing graphene heat-dissipating film coil.
