摘要：

The performances of the novel intumescent flame retardant (IFR) polypropylene (PP) composites containing melamine phosphate (MP) and tris(1-oxo-2,6,7-trioxa-1-phosphabicyclo[2,2,2]methylene-4) phosphate (TPMP) were investigated. The flame retardancy of IFR-PP system was characterized by limiting oxygen index (LOI) and UL 94 and cone calorimeter. The morphology of the char obtained after cone calorimeter testing was studied by scanning electron microscopy (SEM). The thermal oxidative degradation (TOD) of the composites was investigated by using thermogravimetric analysis (TGA) and real-time Fourier transform infrared spectroscopy (RT-FTIR). Compared with the PP/ TPMP or PP/ MP binary composite, at the same addition level, the LOI values of the PP/MP/TPMP ternary composites increase and reach V-0 at the suitable MP/TPMP ratio. The results of TGA and RT-FTIR showed the existence of the interaction between IFR and PP. Copyright (C) 2008 John Wiley & Sons, Ltd.
