Abstract: Provided are a polycarbonate alloy material with good color stability, and a preparation method thereof and use thereof. The polycarbonate alloy material with good color stability includes the following components in parts by weight: 50-90 parts of polycarbonate, 1-20 parts of an acrylonitrile-butadiene-styrene copolymer, 5-20 parts of a flame retardant, 1-25 parts of a toughening agent, 0.1-2 parts of a stabilizer, and 0.1-5 parts of an anti-dripping agent. The polycarbonate alloy material not only has good thin-wall flame retardance, but also has a higher tensile strength retention rate after long-term thermo-oxidative aging, a browning problem is obviously improved, and a use scenario is wide.
