摘要

In this study, a novel flame retardant 1,2-bis (dimelaminium of 1-nitro-3,5-diphospha-4-oxa-3,5-dihydroxy cyclohexane) ethane (EAPM) was synthesized by ethylene diamine tetra (methylene phosphonic) acid (EDTMPA) and melamine in two steps. Meanwhile, its molecular structure was determined by Fourier-transform infrared spectroscopy (FT-IR), elemental analysis, ~1H-NMR. The thermal properties were characterized by TG and DTG, which indicated the good thermostability of EAPM for processing and the considerable residual char in the final stage of combustion. The fire performance of composites blended by the novel flame retardant and polypropylene waere investigated by limiting oxygen index (LOI) and vertical burning test. The results demonstrated the treated PP with the optimal flame retardant formulation of 15 w% EAPM, 5 w% charring agent and 10 w% MEL-APP was attached with an LOI of 33.3% and UL-94 V-0 rating.
