Abstract

An object is to obtain a flame-retardant polyester-based resin composition that uses no halogen-based flame retardant, has high flame retardance, and is excellent in strength retention after long-term heat resistance test under high temperature. The flame-retardant polyester-based resin composition according to the present invention contains 100 parts by weight of a thermoplastic polyester-based resin (A), 5 to 80 parts by weight of an organophosphorus-based flame retardant (B) represented by the following general formula 1, and 1 to 20 parts by weight of at least one amorphous thermoplastic resin (C) selected from the group consisting of a polyetherimide resin, a polysulfone-based resin, and a polyarylate resin. (wherein n is an integer of 2 to 40)

Claims (8)

1 . A flame-retardant polyester-based resin composition comprising: 100 parts by weight of a thermoplastic polyester-based resin (A); 5 to 80 parts by weight of an organophosphorus-based flame retardant (B) represented by the following general formula 1; and 1 to 20 parts by weight of at least one amorphous thermoplastic resin (C) selected from the group consisting of a polyetherimide resin, a polysulfone-based resin, and a polyarylate resin.

(wherein n is an integer of 2 to 40)

2 . The flame-retardant polyester-based resin composition according to claim 1 , wherein the thermoplastic polyester-based resin (A) is polyalkylene terephthalate.

3 . The flame-retardant polyester-based resin composition according to claim 1 , further comprising 5 to 120 parts by weight of an inorganic filler (D).

4 . A molded article of the flame-retardant polyester-based resin composition according to claim 1 .

5 . The flame-retardant polyester-based resin composition according to claim 2 , further comprising 5 to 120 parts by weight of an inorganic filler (D).

6 . A molded article of the flame-retardant polyester-based resin composition according to claims 2 .

7 . A molded article of the flame-retardant polyester-based resin composition according to claim 3 .
