Beschreibung
Zusammenfassung:	The invention relates to a preparation method of a phosphorus-nitrogen-containing castor oil-based flame-retardant plasticizer. The preparation method comprises the following steps: S1, mixing castor oil, double-bond-containing dianhydride and an amine catalyst for reaction to obtain carboxyl-terminated vinyl castor oil; s2, mixing and reacting the carboxyl-terminated vinyl castor oil, glacial acetic acid, hydrogen peroxide and phosphoric acid to obtain epoxy carboxyl-terminated castor oil; s3, mixing and reacting the epoxy carboxyl-terminated castor oil, DOPO and an acid catalyst to obtain phosphorus-containing carboxyl-terminated castor oil; s4, mixing and reacting the phosphorus-containing carboxyl-terminated castor oil and an amine compound to obtain the phosphorus-nitrogen-containing castor oil-based flame-retardant plasticizer. The invention also relates to the castor oil-based flame-retardant plasticizer containing phosphorus and nitrogen prepared by the preparation method. The invention also relates t
