| titleOfInvention | Synthesis method of Schiff base phosphazene double-base structure flame retardant and modified polyurethane flame retardant |
| abstract | The invention discloses a synthesis method of a Schiff base phosphazene double-base structure flame retardant, which comprises the following steps of S1, reacting hexachlorocyclotriphosphazene with a compound containing hydroxyl and active carbonyl, strong base and weak acid salt and a solvent to prepare a phosphorus nitrile-containing intermediate; s2, reacting the phosphorus-containing nitrile intermediate prepared in the step S1 with an alcohol amine compound and a solvent to prepare the flame retardant containing the Schiff base phosphazene double-base structure; the synthesis method of the modified polyurethane flame retardant comprises the step of applying the prepared flame retardant with the Schiff base phosphazene double-base structure to waterborne polyurethane to prepare the waterborne polyurethane flame retardant containing the hydroxyl-terminated Schiff base phosphazene double-base structure. The flame retardant with the Schiff base phosphazene double-base structure can effectively improve the flame retardance and the anti-dripping property of the base material; the Schiff base structure contained in the modified polyurethane flame retardant structure has certain stability, the crosslinking of a melt and the formation of residual carbon can be promoted, the melt dripping resistance of the prepared flame retardant material is improved, and the nitrogen and phosphorus elements in a phosphazene ring can be flame-retardant in a synergistic manner, so that the flame retardant material has a good flame-retardant effect. |
