Abstract
The present invention relates to a flame retardant resin composition including (A) 100 parts by weight of a blend resin composition including a styrene copolymer and a polyester elastomer, (B) 1 to 30 parts by weight of an epoxy resin, and (C) 1 to 30 parts by weight of a phosphor-based flame retardant agent. The flame retardant resin composition has improved flame retardant properties and flexibility and is used for coating a wire and a cable.
Claims19
A flame retardant resin composition, comprising:
- (A) 100 parts by weight of a blend resin composition including a styrene copolymer and a polyester elastomer in a ratio of 20 to 60 parts by weight:40 to 80 parts by weight, respectively;
- (B) 1 to 30 parts by weight of an epoxy resin;
- and
- (C) 1 to 30 parts by weight of a phosphor-based flame retardant agent,
- wherein the epoxy resin comprises a four-functional resin compound represented by the following Formula 2:
- in the above Formula 2, X is a linear chain or branched chain alkyl group having 1 to 30 carbon atoms, a linear chain or branched chain aryl group having 1 to 30 carbon atoms, a linear chain or branched chain alkyl group having 1 to 30 carbon atoms and including an oxygen atom or a nitrogen atom, or a linear chain or a branched chain aryl group having 1 to 30 carbon atoms and including an oxygen atom or a nitrogen atom,
- wherein the styrene copolymer is an alkyl acrylate-styrene-acrylonitrile-based graft copolymer (ASA copolymer), and
- wherein the polyester elastomer is a thermoplastic block copolymer with (i) 40 to 80 parts by weight of a crystalline hard segment and (ii) 60 to 20 parts by weight of a soft segment.
