description	The invention provides a formaldehyde-removing PVC film additive and a preparation method thereof as well as a formaldehyde PVC film and a preparation method thereof, and belongs to the technical field of chemical synthesis. The formaldehyde-removing PVC film additive is iron and nitrogen-doped modified titanium dioxide, the modified titanium dioxide serves as a photocatalyst to catalyze formaldehyde decomposition, and the light sensitivity of nano titanium dioxide can be improved by doping Fe and N, so that the catalytic ability of the nano titanium dioxide is improved. The formaldehyde-removing PVC film comprises the following components: PVC resin powder, a plasticizer, a coupling agent, a stabilizer, diatomite powder, a formaldehyde-removing PVC film additive, chromic acid, graphene powder, a lubricant and a flame retardant. In the preparation method of the formaldehyde-removing PVC film, plastication-calendering is adopted to prepare the film, the prepared film maximally protects the physical and chemica
