The invention discloses a compound multifunctional and environment-friendly attapulgite/kieselguhr-based indoor wall material. The compound functional material is prepared through a dip-calcination method. Raw materials including, by mass, 30-50% of attapulgite, 30-50% of kieselguhr, 10-15% of nano-TiO2 powder and 10-15% of nano-ZnO powder are weighed for use; the nano-TiO2 powder and the nano-ZnO powder are added into water to be prepared into suspension with the mass concentration of 3-5%; attapulgite and kieselguhr are added into the suspension, rapid stirring and mixing are carried out for 1-2 h, and then filtering is carried out; a filtering product is dried and then calcined for 1-2 h at 350-450 DEG C, and the compound functional material is obtained. Filler includes coarse whiting, ash calcium powder, calcined kaolin and silica sand, and auxiliaries include a thickener, wood fibers, dispersible adhesive powder, a thixotropic lubricant and a water reducer. Nano-TiO2 and nano-ZnO are loaded on the surfaces of attapulgite and kieselguhr, then attapulgite, kieselguhr, the filler and the auxiliaries are stirred and mixed, and the environment-friendly indoor wall material is prepared; the problem that nano-TiO2 and nano-ZnO are seriously agglomerated in an environment-friendly indoor wall material is effectively solved.
