Title: Synthesis and Characterization of New Nitrogen-Phosphorus Flame Retardant
Abstract: N,N′-2-(dimethoxy phosphoryl) urea was synthesized with formaldehyde,urea and trimethyl phosphate as materials.The process conditions such as optimal addition method,ratio in feed,reaction time and reaction temperature were determined through the experiment.The structures of the obtained compounds were identified by IR and 1H NMR.Excellent thermal stability and char forming characteristics of this compound were indicated by TGA and DSC.The compound could be used as flame retardant.
