FLAME-RETARDANT RESIN COMPOSITION AND ITS MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain a flame-retardant composition having high heat resistance, excellent impact resistance and further high flame retardance. SOLUTION: This flame retardant resin composition comprises (A) a polycarbonate-based resin, (B) a silicone resin constituted of a siloxane unit represented by RSiO1.5 (T-unit) and a siloxane unit represented by R3SiO0.5 (M-unit), or a silicone resin constituted of the T-unit, the M-unit and a siloxane unit represented by SiO2.0 (Q-unit) [R is a 1-10C (un)substituted monovalent hydrocarbon], and (C) a drip-preventing agent in the amounts regulated so as to be 0.1-9 pts. wt. of the silicone resin (B) and 0.01-10 pts.wt. of the drip- preventing agent (C) based in 100 pts.wt. of the polycarbonate-based resin (A).
