Flame-retardant aromatic polycarbonate resin masterbatch and its manufacturing method

Abstract

A flame-retardant aromatic polycarbonate resin masterbatch is provided, comprising: (A) aromatic polycarbonate resin, (B) an organohydrogen polysiloxane with a weight average molecular weight of 700 to 7,000 as shown in formula (1), and (C) an additive selected from (i) phosphorus-based antioxidants, etc., wherein the masterbatch comprises at least 20% by mass of an aromatic polycarbonate resin with an MVR of 2 to 8 cm3 / 10 minutes as determined by ISO 1133-1 at 300°C and under a load of 1.2 kg relative to the total mass of component (A). (R1~R7 are alkyl, etc., Ar is aryl, x is 1 or 2, a is 0 < a ≦ 0.03, b is 0 < b ≦ 0.30, c is 0 ≦ c ≦ 0.45, d is 0.20 ≦ d ≦ 0.70, e is 0 ≦ e ≦ 0.20, f is 0 ≦ f ≦ 0.70, a+b+c+d+e+f is 1).
