Abstract: The present invention discloses a method for preparing active carbon-based special synthetic paper, comprising stirring polyurethane particles and a solvent in a reactor, and standing to completely dissolve the polyurethane particles to obtain a polyurethane solution; adding active carbon in the obtained polyurethane solution, stirring and mixing uniformly to obtain a solid-liquid mixture; coating the obtained solid-liquid mixture onto a piece of release paper, soaking the release paper and the solid-liquid mixture into an aqueous solution of silver nitrate, completely curing the solid-liquid mixture to form a film, and soaking the release paper and the film into an aqueous solution of sodium chloride; drying the obtained release paper and the film in an electric blast drying oven, and stripping the film from the release paper to obtain the active carbon-based special synthetic paper. In the present invention, the adsorption of harmful substances in the environment is greatly improved.
