NOVELTY - High thermal conductivity three-dimensional graphene oxide composite functional particle modified natural rubber comprises 100 pts. wt. natural rubber, 9 pts. wt. rubber additives and 10-25 pts. wt. three-dimensional graphene oxide high thermal conductivity composite filler. USE - High thermal conductivity three-dimensional graphene oxide composite functional particle modified natural rubber. ADVANTAGE - The high thermal conductivity three-dimensional graphene oxide composite functional particle modified natural rubber has simple preparation, and is easy to implement and industrialized production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the high thermal conductivity three-dimensional graphene oxide composite functional particles modified natural rubber, which involves first putting the thermally conductive spherical inorganic fillers into an oven at 80 degrees C and baking them to a constant weight, and then dispersing them in the dopamine aqueous solution for reaction, suction filtering, washing, and drying to obtain a thermally conductive spherical inorganic filler coated with polydopamine on the surface, adding deionized water to graphene oxide slurry, ultrasonic and mechanical stirring at the same time, to prepare graphene oxide aqueous dispersion, adding the thermally conductive spherical inorganic filler with polydopamine on the surface to the graphene oxide aqueous dispersion, and reacting for 24 hours under stirring to obtain three-dimensional oxide Graphene high thermal conductivity composite filler dispersion, adding filler dispersion into the natural rubber latex, stirring continuously to make the mixing uniform, adding formic acid to break the emulsion to obtain raw rubber, putting the raw rubber from which formic acid has been removed into an oven to dry, and then placing the dried raw rubber in an internal mixer at 60 degrees C and 40 rotations/minute for mastication, and adding zinc oxide and stearic acid in sequence, mixing for 2 minutes and discharging the rubber compound, adjusting the cavity temperature of internal mixer to 150 degrees C, putting the obtained rubber compound into the internal mixer, mixing for 5 minutes and then discharging it again, cooling the rubber material to room temperature, transferring to an open mill for further mixing, during the mixing process, adding the vulcanization accelerator N-(diethylene oxide)-2-benzothiazole sulfenamide and sulfur, mixing rubber material until uniform to obtain a mixed rubber, parking for 20 hours, vulcanizing and molding on a flat vulcanizer to obtain the composite material.
