The invention discloses an efficient antibacterial polycarbonate composite material and a preparation method thereof, and belongs to the antibacterial field of polymer composite materials. The efficient antibacterial polycarbonate composite material is prepared from 80 parts of PC, 5 parts of POE-g-MAH, 5 parts of glass fibers, 1 to 10 parts of a composite antibacterial agent and 0.5 part of dioctyl phthalate, wherein the composite antibacterial agent is PHMG-ECH-coated Fe3O4-TA. PHMG-ECH-coated Fe3O4-TA is adopted as a composite antibacterial agent, two antibacterial materials of PHMG and Fe3O4 are combined to achieve a synergistic antibacterial effect, the composite antibacterial agent is good in compatibility with a matrix through modification, easy to disperse and excellent in mechanical property, the problem that common polycarbonate is poor in antibacterial property is solved, and the composite antibacterial agent is suitable for multiple fields. Meanwhile, a new thought and exploration are provided for
