Abstract
A novel phosphorus-nitrogen flame retardant polyols (FRPE) was synthesized from condensation reaction with adipic acid (AA), ethylene glycol (MEG), diethylene glycol (DEG), maleic acid (MA), 9, 10-dihydro‐9‐oxa‐10‐phosphaphenanthrene‐ 10‐oxide (DOPO) and tris (2-hydroxyethyl) isocyanurate (THEIC) as raw materials. The structure of FRPE was characterized by Fourier transform infrared spectrometry (FTIR),thermogravimetric analysis (TG) and Gel permeation chromatography (GPC). FRPE was used as a flame retardant in the preparation of thermoplastic polyurethanes (TPU). The effects of FRPE on the mechanical, thermal, and flame retardant properties of TPU were investigated. The another aim of this study is an investigation of the effect of different oxidation state of phosphorus in phosphorus-based flame retardants on the thermal and flame retardant properties of TPU. Three different oxidation states of phosphorus (triphenylphosphite (TPPI) (+3), triphenylphosphate (TPP) (+5), and FRPE (+1)), with different thermal stabilities at a constant phosphorus content (0.8 wt%) have been utilized. Thermal and flame retardant properties were evaluated by TGA and cone calorimetry test (CCT), respectively. the surface morphology of char residue after CCT was observed by scanning electron microscopy (SEM). the flame-retardant mechanism of these three flame retardant were investigation by FTIR-TG. The result show that the flame retardant properties of TPU composites were significantly improved, and the flame retardant mechanism of different oxidation state phosphorus flame retardants are presented.
