NOVELTY - Method for producing graphene particles involves (a) obtaining raw materials comprising 98.905-98.36 %mass polypropylene powder, 0.2-0.25 %mass antioxidant powder, 0.1-0.2 %mass lubricant, 0.46-0.5 %mass initiator, 0.3-0.6 %mass tourmaline powder, 0.025-0.05 %mass graphene and 0.01-0.04 %mass fluorine powder, (b) mixing the raw materials in a mixing device for 3 times by premixing involving mixing 20% of polypropylene and raw materials in the mixing device to form a premix, intermixing by adding 20% of polypropylene powder to the premix for intermixing to form an intermix and fine mixing by adding remaining 60% polypropylene powder to the intermix to form a fine mixture, (c) pelletizing, heating the fine mixture at 25 degrees C and extruding filaments through a screw extruder, (d) cooling the filament through a water tank, (e) air-drying through an air-drying device, and (f) pelletizing and cutting into pellets through a pelletizing device. USE - The method is useful for producing graphene particles.
