NOVELTY - Graphene thermally conductive silicone oil comprises 15-60 pts. wt. component A and 41-87 pts. wt. component B. The component A comprises 1-3 pts. wt. activated graphene, 0.1-1 pts. wt. aqueous ammonia, 1-3 pts. wt. coupling agent and 100-300 pts. wt. ethanol. The component B comprises 40-85 pts. wt. dimethicone and 1-2 pts. wt. wetting agent. USE - The silicone oil is useful for high-power LEDs. ADVANTAGE - The silicone oil has good stability, and the service life and thermal conductivity are significantly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the graphene thermally conductive silicone oil, comprising (i) vacuum-drying graphene at 65-90°C for 1-2 hours to obtain activated graphene, (ii) taking the graphene heat-conducting silicone oil for high-power LEDs, (iii) adding the activated graphene, coupling agent and aqueous ammonia to ethanol in sequence, stirring at room temperature for 12 to 24 hours, suction filtering and drying to obtain component A, (iv) adding dimethicone and wetting agent in 15-60 pts. wt. A component at 60-100°C, uniformly stirring, ultrasonically processing for 30-60 minutes to obtain the graphene heat-conducting silicone oil precursor, (v) heating the graphene heat-conducting silicone oil precursor and maturing in vacuum at a constant temperature for 1-2 hours to obtain the cured graphene heat-conducting silicone oil precursor, and (vi) stirring the cured graphene heat-conducting silicone oil precursor in vacuum for 12-48 hours.
