The invention relates to the technical field of organic polymer materials, in particular to a preparation method of a flame-retardant and glass fiber reinforced polycarbonate material. The method adopts a co-rotating parallel twin-screw extruder and uses special kneading elements FME32/32 as well as improved thread elements SFV32/32 and SFVN32/32 to prepare the flame-retardant and glass fiber reinforced polycarbonate under specific screw combination conditions. Compared with the prior art, the preparation process features stable strip extrusion, the pellets are white and transparent with a proper melt flow index and a high impact strength index. The material can provide downstream parts and products with excellent appearance and color selectivity, outstanding flame retardant performance, excellent mechanical properties such as impact resistance, and good processability at the same time.
