| description | The invention discloses an in-situ synthesis method of a nitrogen- and phosphorus-doped phenolic resin composite material and application thereof. The synthesis method comprises the following steps: (1) dispersing a carrier, which is rich in hydroxyl on the surface, in water to obtain a dispersion A; (2) dissolving hexamethylenetetramine and concentrated phosphoric acid in water, adding a phenol reagent and mixing to obtain a solution B, heating to 90-110 DEG C, adding the dispersion A and carrying out a primary reaction for 1-12 h; and (3) carrying out a secondary reaction on the solution obtained after the primary reaction in the step (2) at 40-60 DEG C for 1-12 h so as to obtain the nitrogen- and phosphorus-doped phenolic resin composite material. According to the invention, hexamethylenetetramine is decomposed under the catalytic condition of concentrated phosphoric acid to generate formaldehyde and amine, followed by an in-situ reaction with phenols. The concentrated phosphoric acid is used as a catalyst |
