The invention discloses a non-woven fabric capable of eliminating static and continuously releasing negative oxygen ions and a preparation method thereof. The non-woven fabric is characterized by being prepared from, by weight, 1-2 parts of carbon fibers, 2-7 parts of nano-tourmaline powder, 1-2 parts of talcum powder, 5-10 parts of polylactic acid, 1-2 parts of polyethylene glycol 200, 3-5 parts of activated carbon, 4-8 parts of mint essence, 1-2 parts of silicon dioxide, 50-70 parts of isotactic polypropylene, 2-6 parts of diatomite, 1-2 parts of sodium dodecyl sulfate, a proper amount of carboxymethyl cellulose sodium and a proper amount of water. As nano-tourmaline powder is added in the non-woven fabric, the non-woven fabric can achieve the effect of continuously releasing negative oxygen ions, and can make the interior space of an automobile cool, refreshing and comfortable and make people in the automobile refreshed when applied to automobile interior decoration, and in cooperation of mint essence, the refreshing effect is significant; in cooperation with added carbon fibers and the like, the material has the advantage of eliminating static.
