The invention discloses phosphorus-nitrogen synergistic flame-retardant polyalcohol and a preparation method thereof, relating to the synthesis of flame-retardant polyalcohol. The preparation method of the phosphorus-nitrogen synergistic flame-retardant polyalcohol comprises the following steps: 1) with quaternary phosphorus salt as a raw material, adding alkali and stirring for reacting, filtering and separating the salt generated by reacting, then oxidizing with a hydrogen peroxide solution, and performing reduced-pressure distillation for removing moisture to obtain tris(hydroxymethyl)phosphine oxide; 2) performing an ether exchange reaction between hexakis(methoxymethyl)melamine and the tris(hydroxymethyl)phosphine oxide obtained in the step 1) at 50-100 DEG C in the presence of an acid catalyst, and reducing pressure for removing small-molecular methanol to obtain the phosphorus-nitrogen synergistic flame-retardant polyalcohol. The prepared phosphorus-nitrogen synergistic flame-retardant polyalcohol is formed by connecting phosphorus elements through phosphorus-carbon bonds, and the weakness that the phosphorus-carbon bonds (phosphorus-ester bonds) are hydrolyzed easily is avoided, thus the phosphorus-nitrogen synergistic flame-retardant polyalcohol has the characteristic of relatively high hydrolysis resistance.
