Fireproof wear-resistant fabric

[0076] The preparation method of described polyditrimethylolpropanethiophosphorylurea (PDTPT), comprises the following steps:

[0077] (1) Synthesis of intermediate ditrimethylolpropane diphosphoryl chloride (DTDC)

[0078] Add a certain proportion of ditrimethylolpropane (DTMP) and solvent dichloroethane into the four-neck flask, slowly raise the temperature to 40°C under electric stirring, and add POCl after DTMP is completely dissolved 3 , and use lye to absorb the HCl gas produced by the reaction, keep it warm for 6 hours, cool to room temperature after the reaction, and distill off the solvent dichloroethane and unreacted POCl under reduced pressure 3 , to obtain a white solid crude product, after adding a certain amount of absolute ethanol, put it in a freezer (-20°C) for 2 hours, filter and vacuum dry the obtained white solid at 70°C to constant weight, and then obtain a white powdery solid DTDC .
