Abstract: Application of a Mannich base in a flame-retardant polyurethane material is provided. The Mannich base has a structure represented by a formula (I). In the Mannich base, flame-retardant groups, i.e., halogens are introduced at the second, fourth and sixth positions of a phenyl group, and flame-retardant elements, i.e., halogens and nitrogen are introduced into synthesized polyether polyol, giving the synthesized polyether polyol good flame retardance. The amount of active hydrogen in the Mannich base is small so that occurrence of side reactions during the synthesis of the polyether polyol is reduced, and the viscosity of the flame-retardant polyether polyol is lowered. Due to autocatalytic performance of tertiary amido in the flame-retardant polyether polyol, use of a catalyst can be reduced and even avoided during the synthesis. A preparation method of the Mannich base is also provided.
