Abstract

A polycarbonate resin composition containing, relative to 100 parts by mass of a resin composed of: (A) 40 to 100% by mass of a recycled aromatic polycarbonate resin; and (B) 0 to 60% by mass of an aromatic polycarbonate resin to amount to a total of 100% by mass, (C) 10 to 60 parts by mass of carbon fibers surface-treated with a polyamide, (D) 20 to 40 parts by mass of a phosphate compound, and (E) 0.01 to 1 part by mass of a fluorine compound.

Claims

1. A polycarbonate resin composition comprising, relative to 100 parts by mass of a resin composed of:

(A) 40 to 100% by mass of a recycled aromatic polycarbonate resin; and

(B) 0 to 60% by mass of an aromatic polycarbonate resin to amount to a total of 100% by mass,

(C) 10 to 60 parts by mass of carbon fibers surface-treated with a polyamide,

(D) 20 to 40 parts by mass of a phosphate compound, and

(E) 0.01 to 1 part by mass of a fluorine compound.

2. The polycarbonate resin composition according to claim 1, wherein the component (A) is an aromatic polycarbonate resin recovered from a molded article other than an optical recording medium.

3. The polycarbonate resin composition according to claim 1, wherein the component (A) is an aromatic polycarbonate resin recovered from one or more molded articles selected from beverage containers, optical components, electronic component enclosures, transport cases for electronic components, and building materials.

4. A molded article obtained from the polycarbonate resin composition according to claim 1.
