Preparation method and application of reactive polyurethane flame retardant

The polyurethane flame retardant is prepared by compounding poly(diphosphophosphazene) (PDPP) and derivatives thereof, poly(diphosphate phosphazene) (MPDPP) (where M=Mg 2+ , Ca 2+ , transition metal ions, rare earth ions and the like) and poly(diphosphonic phosphazene).
