The invention provides an antiaging glass fiber-reinforced polycarbonate composition, which comprises the following components in part by weight: 20 to 70 percent of polycarbonate resin, 10 to 35 percent of acrylonitrile-butadiene-phenylethylene polymer, 5 to 40 percent of polyethylene graft, 10 to 30 percent of glass fiber reinforce, 0.3 to 0.5 percent of coupling agent, 0.5 to 3 percent of lubricating agent and 0.1 to 1.0 percent of antioxygen. The polycarbonate composition of the invention is free from surface floating fibers has good glossiness, high mechanical performance, high size stability and high thermal resistance. The anti-boiling water aging performance of the polycarbonate composition is improved greatly. The polycarbonate composition can be widely used in electronic and electrical elements such as electrical tool shells, machine bodies, brackets, external gears, three-way valves, mechanical pump parts and the like and is particularly suitable to be used as engineering plastics for use in wet or hot water environments.
