摘要：

The PDP, a novel intumescent flame retardant (IFR) with high charred residue of 40.8% in N2 at 700 degrees C by TGA was synthesized successfully for preparing halogen-free flame-retardant EPDM composites. The UL-94 V-0 rating was achieved for EPDM composites with 20 phrs carbon black at the same time by using only 60 phrs PDP. In situ FTIR spectroscopy reveals that P-N rich charred residues are formed through the interaction between hydrogen atom in weak base of P-NH-C and phosphate. SEM characterizes the formation of intumescent chars during burning. The mechanical properties of composites are also discussed.
