The invention discloses a nanometer far-infrared diatom ooze functional wall material, and belongs to the technical field of decoration function materials. The nanometer far-infrared diatom ooze functional wall material is prepared from, by mass, 30.0-40.0 parts of refining diatomite, 8.0-15.0 parts of nanometer far-infrared powder, 25.0-30.0 parts of gel material, 2.5-4.0 parts of dispersible adhesive powder, 2.0-4.0 parts of nanometer titanium dioxide, 4.0-30.0 parts of powder stuffing, 0.5-1.0 part of additive, 2.0-3.0 parts of wood fiber and 100-120 parts of water. The nanometer far-infrared diatom ooze functional wall material can maintain the existing performance of diatom ooze of being safe, environmentally friendly, strong in adsorption effect, adjusting air humidity, purifying formaldehyde and bringing convenience to construction, meanwhile play the function of far-infrared radiation, form a certain heat effect to a human body, improve tissue oxygen supply, promote angiectasis, promote blood circulation, enhance human body metabolism, promote discharge of waste in the human body, improve human body immunity, and accordingly achieve the health care effect for the human body.
