<p><P>PROBLEM TO BE SOLVED: To provide a flame retardant thermoplastic resin composition including a plant-derived resin, having superior flame retardancy and practical performances, without using any halogen-based flame retardant. <P>SOLUTION: The flame retardant thermoplastic resin composition includes at least a plant-derived resin (A), a flame retardant (B) and a high-strength fiber (F); wherein W<SB>1</SB>being the mass% of the plant-derived resin (A), and X<SB>1</SB>being the mass% of the flame retardant (B) and satisfying inequalities 30≤W<SB>1</SB><55.5 and 44.5<X<SB>1</SB>≤70. Of the flame retardant (B), 90 mass% or more is composed of a metal hydrate containing an alkali metal-based substance in an amount of 0.2 mass% or less, and a weight proportion of the high-strength fiber (F) in the total weight of the flame retardant thermoplastic resin composition is 10 mass% or less, and the high-strength fiber (F) is selected from a group of a polyamide fiber, a polyester fiber, an ultra-high strength polyethylene fiber, a polypropylene fiber, a metal fiber and a plant fiber. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
