The invention discloses a preparation method of a formaldehyde adsorption removing agent, which comprises the following three steps: the first step of carrier preparation, that is, uniformly mixing montmorillonite, white active carbon, half-opening expanded perlite, and zeolite to prepare an adsorption carrier; the second step of catalytic oxidizing agent preparation, that is, uniformly mixing sodium perborate, titanium dioxide, light calcium carbonate, alum, and magnesium molybdate, grinding into powder of 100-200 meshes to prepare a catalytic oxidizing agent; the third step of formaldehyde adsorption removing agent preparation, that is, in a catalytic oxidizing agent-atomized air, allowing the adsorption carrier to fully adsorb the catalytic oxidizing agents, spraying the adsorption carrier with polyurethane varnish, aging at room temperature for 12-36 hours, after the polyurethane varnish forms a film, grinding into powder of 60-120 meshes to obtain the formaldehyde adsorption removing agent.
