GLASS-FIBER-REINFORCED POLYCARBONATE RESIN COMPOSITION

摘要

A glass-fiber-reinforced polycarbonate resin composition having a flat cross section and excellent weld strength, stiffness and flame retardancy. The resin comprises:
(A) 100 parts by weight of a resin component (component A) consisting of a polycarbonate-polydiorganosiloxane copolymer resin (component A-1) and an aromatic polycarbonate resin (component A-2);(B) 10 to 300 parts by weight of glass fibers having a flat cross section (component B) which have an average value of the long diameter of the fiber cross section of 10 to 50 μm and an average value of the ratio of the long diameter to the short diameter (long diameter/short diameter) of 1.5 to 8;(C) 5 to 25 parts by weight of an adhesion improving agent (component C);(D) 5 to 45 parts by weight of a phosphorus-based flame retardant (component D); and(E) 0.01 to 3 parts by weight of a fluorine-containing dripping inhibitor (component E),

the content of the polydiorganosiloxane derived from the component A-1 in the resin composition being 0.05 to 4.00 wt %.
