The present invention relates to the technical field of polymer materials. The present invention discloses a flame-retardant material for power connectors. The raw materials of the flame-retardant material comprise: nylon, carbon fiber, glass fiber, flame retardant, silica hollow microbead powder, stearic acid surface-modified nano-calcium carbonate, coupling agent, sodium polyacrylate, seaweed extract, antioxidant, lubricant. The preparation method comprises the following steps: drying pretreatment of nylon; adding carbon fiber, glass fiber, silica hollow microbead powder, stearic acid surface-modified nano-calcium carbonate, stirring and mixing to obtain a premix; adding remaining raw materials into the premix, stirring and mixing to obtain a mixture; feeding the mixture into a twin-screw extruder for melt extrusion, pelletizing, drying and cooling to obtain the flame-retardant material. The flame-retardant material prepared by the present invention not only has excellent flame retardancy, but also outstanding mechanical strength, moisture resistance and insulation.
