description The invention provides a formula and a preparation method of a high-impact low-temperature-resistant flame-retardant PC/PBT alloy material. The alloy material is prepared from the following raw materials in parts by weight: 40-70 parts of PC, 30-60 parts of PBT, 5-15 parts of a flame retardant, 0-5 parts of a synergistic flame retardant, 0.2-5 parts of an ester exchange inhibitor, 2-10 parts of a toughening compatilizer, 2-10 parts of a low-temperature toughening agent and 0.01-0.3 part of an antioxidant. PC and PBT are dried in a drying box; mixing for 2 to 5 minutes in a high-speed mixer at the rotating speed of 100 to 500r/min to obtain a uniform mixture; and carrying out melt extrusion in a twin-screw granulator, cooling material strips through a water tank, and granulating to obtain the high-impact low-temperature-resistant flame-retardant PC/PBT alloy material. The high-impact low-temperature-resistant flame-retardant PC/PBT alloy material has the advantages of excellent flame retardance, low-temperatur
