FLAME-RETARDANT THERMOPLASTIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a flame-retardant thermoplastic resin composition having excellent flame retardance even in a thin molding product in a resin composition comprising a boron-based compound being a non-halogen flame-retardant as a main flameretardant. SOLUTION: This flame-retardant thermoplastic resin composition comprises 100 pts.wt. of (A) 100-50 wt.% of a polycarbonatebased resin and (B) 0-50 wt.% of a polyester-based resin, (C) 1-50 pts.wt. of a zinc borate and/or a zinc borate hydrate comprising >=70 wt.% of particles having <=5μm particle diameter and (D) one or more compounds selecteci from (D1) 0.1-50 pts.wt. of a polyorganosiloxane, (D2) 0.1-50 pts.wt. of talc and (D3) 0.005-1 pt.wt. of a fluorine-based resin.
