The invention discloses a high-strength, fireproof and anti-droplet lignin-based polyurethane foam material and a preparation method thereof. The preparation method comprises the following steps: adding lignin into polyol by adopting a one-pot method, mixing to carry out liquefaction reaction, then adding phosphorus pentoxide to carry out dehydration condensation esterification reaction, finally adding melamine to carry out salt forming reaction to obtain lignin-based phosphonate polyol, and then carrying out nucleophilic addition reaction on the lignin-based phosphonate polyol and isocyanate to obtain lignin-based phosphonate polyol. And molding, demolding and curing. The lignin-based phosphonate polyol prepared by the method contains a large amount of nitrogen/phosphorus flame-retardant elements, no acid-base catalyst is introduced in the preparation process, and 100% replacement of petroleum-based polyol by lignin-based phosphonate polyol is realized. The prepared lignin-based polyurethane ...
