Abstract: The present invention discloses a method for preparing titanium dioxide-based synthetic paper, comprising steps of using titanium dioxide and polyurethane as main raw materials, stirring and mixing titanium dioxide powder and the prepared polyurethane solution, subsequently curing to form a film to obtain the titanium dioxide-based synthetic paper. The synthetic paper product of the present invention is of a porous structure which facilitates the adsorption of organic pollutants in the indoor air. During the production, lots of pores are formed both on the surface of the synthetic paper and inside the synthetic paper, by which the adsorption of the organic pollutants in the indoor air by the synthetic paper is improved greatly. It can effectively degrade organic pollutants under mild conditions. Inorganic filler can degrade the organic pollutants adsorbed onto the surface of the synthetic paper and inside the synthetic paper, with only nontoxic substance generated.
