FLAME-RETARDANT COMPOSITE POLYLACTIC ACID TYPE THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant composite polylactic acid type thermoplastic resin composition which drastically improves flame-retardancy of a polylactic acid type thermoplastic resin composition originally having high inflammability, has improved balanced properties of heat-resistance, impact resistance strength, elastic modulus or the like and widens a product application range of a molded article.

SOLUTION: The flame-retardant composite polylactic acid type thermoplastic resin composition is prepared by adding 50 to 200 pts.wt. of aromatic polycarbonate resin (C), 1 to 50 pts.wt. of a fire-retardant (D) and 1 to 50 pts.wt. of polyethylene naphthalate fiber (E) to 100 pts.wt. of polylactic acid type thermoplastic resin component consisting of 10 to 95 wt.% of polylactic acid resin (A) and 90 to 5 wt.% of rubber-containing styrene based resin (B). The polyethylene naphthalate fiber (E) is prepared by depositing 0 to 3.0 pts.wt. of phosphor element based on the weight of fiber.
