A flame-retardant polyether polyol is provided, including a Mannich base and an epoxide. The epoxide is selected from ethylene oxide, propylene oxide and butylene oxide. 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. The amount of active hydrogen in the Mannich base is small so that side reactions during synthesis of the polyether polyol are reduced, and the viscosity of the polyether polyol is lowered. A flame-retardant polyurethane material is also provided, synthesized from raw materials comprising the above-mentioned flame-retardant polyether polyol and an isocyanate. 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.
