The invention discloses a self-cleaning runway material and a preparation method thereof, and relates to the field of runway materials. The self-cleaning runway material mainly comprises the followingraw materials in parts by weight: 10-18 parts of titanium dioxide, 50-80 parts of sepiolite, 10-30 parts of porous metal, 100-120 parts of calcium carbonate, 100-150 parts of polypropylene, 5-10 parts of carbon fibers, 130-200 parts of polyurethane, 4-20 parts of talcum powder, 200-300 parts of a diluent, 120-140 parts of nitrile rubber, 40-80 parts of sodium silicate, 20-40 parts of a microbubble assistant, 300-400 parts of a liquid optically clear adhesive (OCA) adhesive, 40-60 parts of a flatting agent and 40-60 parts of an antioxidant. The preparation method has the beneficial effects that emission of toxic substances is reduced by adding porous metal supported adsorption substances, and the adsorption substances comprise talcum powder, titanium dioxide, carbon fibers and the like.
