Abstract

The polyphosphoric ester melamine intumescent flame retardant was synthesized in the presence of polyphosphoric acid,pentaerythritol and melamine.The influence factors on the preparation of the flame retardant,such as reaction temperature,composition of components,the reaction time and solvent were investigated.The experimental results showed that the optimal temperature was the refluxing temperature,the optimal reaction time was 8 h,and the optimal mole ratio of three materials was n(polyphosphoric acid)∶n(pentaerythritol)∶n(melamine) = 3∶1∶(2～3).The prepared flame retardant was characterized by FTIR,TG and DSC.The thermal properties of flame retardant epoxy resin was also investigated.
