The invention relates to the technical field of polymer materials, and discloses a flame-retardant polycarbonate material and a preparation method thereof. The invention adds polycarbonate, sodium sulfonate-modified tris(2-acryloyloxyethyl) isocyanurate, sulfur-containing modified bisphenol fluorene and antioxidant 1068 into a twin-screw extruder for extrusion and granulation, and then molds the pellets in a flat vulcanizing machine to obtain the flame-retardant polycarbonate material. Sulfur, phosphorus, carbon nanotube structures and triazine groups contained in sodium sulfonate-modified tris(2-acryloyloxyethyl) isocyanurate and sulfur-containing modified bisphenol fluorene all have good flame-retardant effects and jointly form a flame-retardant system; moreover, the sulfonate groups therein can catalyze the isomerization and crosslinking of polycarbonate to form carbon, thereby endowing the polycarbonate material with higher carbon-forming ability and better flame-retardant effect.
