The invention discloses a flame-retardant, chemical-resistant and dimensionally stable PC composite material and a preparation method thereof. The flame-retardant, chemical-resistant and dimensionally stable PC composite material comprises, in parts by weight, 40-75 parts of PC, 10-20 parts of PET and 10-30 parts of PCTG. The preparation method is as follows: mixing all components uniformly according to the ratio, adding them into a twin-screw extruder from the main feeding port, and performing melt extrusion to obtain the flame-retardant, chemical-resistant and dimensionally stable PC composite material. The preparation method of the invention is simple, and the prepared PC composite material has the characteristics of excellent chemical resistance, low shrinkage and dimensional stability, and can be used in fields such as control panels of large medical equipment.
