  • Diphenylpropylamidophosphate(DPPAP) was synthesized as flame retardant for Expanded Polystyrene(EPS). Structure of DPPAP was investigated by the m, NMR, DSC. We make FR panels with EPS beads which treated with DPPAP and expanded by expand machines. FR panels were used in this study after formation by form machines and then cutting by cutting machines. The following conclusions were obtained: 1. The new synthetic agent was developed without the use of solvent such as pyridine or tertiary amine in the synthesis of DPPAP which served as flame retardant for EPS. 2. The flame retandancy effect of EPS treated with DPPAP was found excellent in LOI tests. 3. The properties of FR EPS panels treated with DPPAP did not difference.
