Disclosed are a far-infrared emitting material and its preparation method. The far-infrared emitting material includes zirconium monoxide and at least one natural silicate mineral soil; the far-infrared emitting material and its preparation method use at least two of the above materials as raw materials, which are mixed according to a specific proportion, sintered, and crushed into granules. In the preparation method, the material is sintered within a temperature range of 1100-1250° C. and evenly mixed to form a slurry by a ball mill. The slurry is dispersed by adding an additive when needed and finally sifted, baked, dried to form a dry powder which is sifted to form a far-infrared emitting material with high emissivity and wide wavelength in the range of 8-20 μm.
A far-infrared emitting material, comprising:
A preparation method of a far-infrared emitting material, using at least two infrared emitting materials of any one of the claims 1 to 6 as raw materials which are mixed according to a specific proportion, sintered, and crushed into granules, characterized in that the raw materials are sintered within a temperature range of 1100-1250° C., and then evenly mixed to form a slurry by a large ball mill, an additive is added when needed and dispersed, and finally the slurry is sifted, baked, dried to powder, and sifted to produce the far-infrared emitting material with a high emissivity and a wide wavelength in the range of 8-20 μm;
