UV Manufacturing Method of Graphene flakes Graphene flakes Manufactured by the method Manufacturing Method of graphene flakes UV resin using the same and steel pipe piles coated thereof
The present invention relates to a method for manufacturing graphene flakes, graphene flakes manufactured by the method, a method for manufacturing a graphene flake UV powder resin by using the same, and a steel pipe pile coated therewith. More specifically, the method for manufacturing graphene flakes comprises the steps of: adding iron (Fe) melt, which is an interlayer exfoliation material, to layered graphite to manufacture iron-inserted layered graphite; pulverizing the manufactured iron-inserted layered graphite with plasma, and feeding the iron-inserted layered graphite into water to cooling the same so that carbon particles float in water and iron particles precipitate into the water; recovering the carbon particles floating in the water to manufacture water-dispersed graphene flakes; mixing an epoxy oligomer emulsion with the manufactured water-dispersed graphene flakes, and drying the mixture; pulverizing the dried mixture to manufacture graphene dispersion for epoxy powder; adding an epoxy oligomer resin, a curing agent, and a photoinitiator to the manufactured graphene dispersion for epoxy powder, and mixing the same; feeding the mixture into an extruder, melting and extruding the same at a temperature of 100 to 110℃, and cooling and pressing the same to manufacture the mixture into pieces; and pulverizing the manufactured piece-shaped mixture to manufacture a graphene flake UV powder resin. Therefore, a large amount of graphene flakes that can be easily collected and do not cause environmental pollutions can be manufactured.
