FLAME RETARDANT POLY(LACTIC ACID)-BASED RESIN COMPOSITION AND MOULDED MATERIAL USING THE SAME

摘要

is a resin composition composed mainly of polylactic acid resin (A). A flame retardant (B) 10 ~ 33 % by weight contain . The flame retardant (B) is an organic phosphonic acid containing a metal salt -based flame retardant (B1). The drip inhibitor (C) to that containing 0.1 to 2% , it is suitable to the glass fiber (D) containing 5 to 50 mass % . Flame retardant (B) is an organic phosphonic acid containing a metal salt -based flame retardant (B1) and ammonium polyphosphate based flame retardant (B2) , and the mass ratio of the organic phosphinic acid metal salt -based flame retardant (B1) and ammonium polyphosphate based flame retardant (B2) (B1 / B2) is January 1 to January 20 of it is appropriate .
