Preparation method of Mannich flame-retardant polyether polyol |
| abstract |
The invention belongs to the technical field of preparation of flame-retardant polyether polyol, and particularly relates to a preparation method of Mannich flame-retardant polyether polyol. The method comprises the steps of adopting an aromatic phenol compound, paraformaldehyde or a formaldehyde aqueous solution to react with diethanol amine to prepare Mannich base, reacting the Mannich base with phosphorus oxychloride to generate a chlorine and phosphorus element modified Mannich base initiator, simultaneously controlling the proportion and the feeding mode of the phosphorus oxychloride, modifying Mannich base molecules through phosphorus oxychloride groups to synthesize a macromolecular Mannich base initiator with higher functionality, and finally carrying out polymerization reaction on the macromolecular Mannich base initiator and alkane oxide to obtain the special Mannich flame-retardant polyether polyol. |
