Abstract

A flame retardant resin composition composed of a thermoplastic resin (polyester resin, etc.) (A) and a flame retardant (B), the flame retardant (B) containing a polyphenylene ether resin (B1), a phosphate ester ( Condensed phosphoric acid ester, etc.) (B2), polyphosphate salt of nitrogen-containing cyclic compound (B3). The nitrogen-containing cyclic compound includes an amino group-bearing triazine compound (melamine, melamine condensate, etc.). The ratio of a flame retardant (B) is about 10-300 weight part with respect to 100 weight part of polyester resins (A). The flame retardant (B) can contain 10 to 500 parts by weight of polyphenylene ether resin (B1) and 5 to 1000 parts by weight of polyphosphate ( B3).

Description

Technical field [0001] The present invention relates to a flame-retardant resin composition for flame-retarding thermoplastic resins such as polyester resins, a method for preparing the same, and a molded body formed from the flame-retardant resin composition. Background technique [0002] Thermoplastic resins such as polyester resins have excellent mechanical properties, electrical properties, weather resistance, water resistance, chemical resistance, and solvent resistance. For this reason, it is used as an engineering plastic for various applications such as electrical and electronic parts, mechanical mechanism parts, and automobile parts. In addition, with the expansion of application fields and improvement of mechanical properties for polyester resins, flame retardancy is required from the perspective of safety. It is known that a general flame retardant method is to add a flame retardant using a halogen compound and an antimony compound to a thermoplast...
