| description | The invention provides a phosphamide-containing DOPO derivative as well as a preparation method and application thereof, and relates to the technical field of flame-retardant materials. The preparation process of the phosphoramide-containing DOPO derivative comprises the following steps: enabling BPOD to react with PHBA or Na-PHBA to obtain B-PFPH-PHP, enabling DPH-CPP to react with PPDA to obtain DPH-PAPH-APH, enabling the B-PFPH-PHP to react with the DPH-PAPH-APH to obtain a Schiff base intermediate, and finally enabling the Schiff base intermediate to react with DOPO to generate the phosphoramide-containing DOPO derivative. The derivative can be used as a reactive flame retardant to be applied to curing and production of EP and PU, the flame retardance and mechanical properties of EP and PU are improved, and the PHPA-DOPO active ingredient has good stability, cannot be separated out and degraded from the material after being placed for a long time, and cannot cause adverse effects on the environment.
