Synthesis of Phenoxy Triazine Oligomers and Study on Intumescent Flame Retardant ABS

A novel phenoxy triazine charring agent which contained two flame-retardant elements of nitrogen and phosphorus was synthesized with satisfying yield.Some factors which affected the reaction were investigated.The structures of the phenoxy triazine charring agent was characterized by FTIR,element analysis apparatus,melting point apparatus,and the contents of chlorine and phosphorus were tested by silver quantitative method and quinoline phosphomolybdate gravimetric method respectively.The intumescent flame retardant(IFR),which was composed of this triazine derivative,ammonium polyphosphate(APP) and red phosphorus was added to ABS.The effects of this flame retardant on the flame retardancy and mechanical property of acrylonitrile-butadiene-styrene terpolymer were studied.The experimental results showed that the yield of this phenoxy triazine oligomer was good,and the IFR synthesized with it had excellent flame retardancy and mechanical property for the acrylonitrile-butadiene-styrene terpolymer.
