Summary:The invention discloses a preparing method of a flame-retardant light-resistant phosphorylation fatting agent. The method comprises the steps that phosphorus pentoxide and castor oil are added into a reaction container according to the proportion to be evenly stirred, phosphorus pentoxide dispersion liquid and the castor oil which are prepared in the above step and added in the container are added into a 250 ml three-opening bottle to be evenly stirred, a catalyst is added into the container, the temperature rises to 70 DEG C, the condensation backflow heat preservation reaction is carried out for 1h, and a product C is obtained; 2.5g of 2-hydroxy ethyl trimethyl ammonium chloride is added into the product C to be evenly stirred, the temperature rises to 80 DEG C, the heat preservation reaction is carried out for 1 h, 2.5g of sorbitol, 1.5g of ammoniummolybdat, 2.5g of cyanuric acid, 1.1g of oleamide and 1.2g of 1-(3-propyl dimethyl amine)-3-ethyl carbodiimide are added, the temperature rises to 60 DEG C, the
