The invention discloses a graphene high-heat-dissipation fiber and a preparation method thereof. The method comprises the following steps: step 1, weighing raw materials; step 2, preparing graphene ultrafine powder; step 3, stirring and mixing the graphene powder and the chinlon powder; step 4, carrying out composite granulation on the mixed powder through melt extrusion; step 5, pouring the composite master batch into a spinning machine, and spinning; step 6, blending the graphene polyamide yarns and viscose acetal fibers into yarns; step 7, preparing high-heat-dissipation slurry; step 8, uniformly coating the surface of the graphene chinlon filament with the high-heat-dissipation slurry; step 9, drying the coated composite fiber; and step 10, the high-heat-dissipation fiber winding drum is loaded with yarn for standby application. The invention also provides the graphene high-heat-dissipation fiber prepared by the method. According to the graphene high-heat-dissipation fiber and the preparation method there
