NOVELTY - Preparation of graphene composite material involves mixing dichloro-dicyanobenzoquinone, potassium persulfate and glass fibers with water, grinding for 2-3 hours, obtaining slurry, spray-drying resultant product, mixing resultant with dimyristoyl phosphatidylinositol, terpinyl acetate, graphene and methyl sulfonic acid mixture, stirring, adding trifluoromethanesulfonimide, mixing for 3-5 hours, reacting at 760-800 degrees C, cooling to 330 degrees C, spray-drying resultant mixture, mixing with deionized water, stirring, granulating, adding resultant to heat-treatment furnace, heating and cooling. USE - Preparation of graphene composite material (claimed). ADVANTAGE - The method enables preparation of graphene composite material having excellent aging resistance. DETAILED DESCRIPTION - Preparation of graphene composite material involves mixing 1-3 pts. wt. dichloro-dicyanobenzoquinone, 2-3 pts. wt. potassium persulfate and 10-15 pts. wt. glass fibers with water, grinding for 2-3 hours, obtaining slurry, spray-drying resultant product, mixing resultant with 1-4 pts. wt. dimyristoyl phosphatidylinositol, 2-7 pts. wt. terpinyl acetate, 9-13 pts. wt. graphene and 4-6 pts. wt. methyl sulfonic acid mixture, stirring, adding 2-5 pts. wt. trifluoromethanesulfonimide, mixing for 3-5 hours, reacting at 760-800 degrees C, cooling to 330 degrees C, spray-drying resultant mixture, mixing with deionized water, stirring, granulating, adding resultant to heat-treatment furnace, heating at 300 degrees C for 2-3 hours and cooling.
