Synthesis and Characterization of a Novel Polyhydroxy Triazine Charring Agent and Properties of its Flame Retarded Polyproylene

Abstract:

In this study, a novel polyhydroxy triazine charring agent (PT-CA) was synthesized through the solid-state reaction of triglycidyl isocyanurate (TGIC) and pentaerythritol. Meanwhile, the molecular structure of the chemical compound was determined by FTIR, elemental analysis and thermalgravimetric analysis (TG).Then it is combined with microencapsulated ammonium polyphosphate (MAPP) and melamine phosphate (MP) to impart flame retardance and dripping resistance for polypropylene (PP).The fire performance of treated PP was investigated by limiting oxygen index (LOI) and vertical burning test (UL-94).It has been found that the treated PP with the optimal flame retardant formulation of MAPP:MA:PTCA=18:6:6 (weight ratio, formulation 10) gives an LOI of 31.5 and UL-94 V-0 rating.
