<p>Disclosed are: a flame retardant agent for a thermoplastic resin, which enables a thermoplastic resin containing the flame retardant agent to keep its viscous property, to be made into a fiber readily, and to exhibit flame retardant effect even when ammonium dihydrogen phosphate is contained in the flame retardant agent as a non-halogen flame retardant component. Also disclosed is a flame retardant resin composition containing the flame retardant agent. Specifically, the flame retardant agent for a thermoplastic resin comprises ammonium dihydrogen phosphate, potassium hydroxide, glycerin and urea, wherein potassium hydroxide is contained in an amount of 10 to 70 parts by weight, glycerin is contained in an amount of 0.1 to 4.0 parts by weight, and urea is contained in an amount of 1 to 9 parts by weight relative to 100 parts by weight of ammonium dihydrogen phosphate. The flame retardant resin composition can be produced by adding the flame retardant agent to a thermoplastic resin (e.g., polyethylene terephthalate) so that the content of the flame retardant agent is 4 to 16 wt% relative to the total amount of the mixture, kneading the mixture, and then shaping the kneaded product.</p> |
