The invention relates to a preparation method of impact resistant polycarbonate, and belongs to the technical field of high-molecular materials. The preparation method comprises the following steps: taking calcium fatty acids, heating, adding monox powder and glass fiber, uniformly mixing, and obtaining modified powder after cooling; initially mixing the modified powder and polyvinyl in a mixing machine, adding ethylene bis stearamide and chlorinated polyethylene, uniformly mixing after heating, and cooling to the room temperature to obtain a precast body; uniformly mixing the precast body, polycarbonate, butanediol diacrylate, an anti-oxidant, a silicane coupling agent and a lubricant to obtain a mixture; feeding the mixture into a double screw rod extruding machine for extrusion pelletization. According to the polycarbonate material provided by the invention, the monox particles are prepared into the precast body through the pre-wrapping method, and then the precast body and PC are subjected to extrusion, so that the mechanical strength is improved.
