Abstract

The invention relates to the field of filtering materials, and discloses a filtering material capable of releasing ecological negative ions and a preparation method thereof. A main body of the filtering material is an air or water body filtering substrate which is loaded with nanometer negative ion powder and is made of a macromolecular material. The preparation method comprises the following steps of (1) mixing negative ion powder, an inorganic dispersant and deionized water, and grinding at high speed, so as to obtain stable dispersing liquid containing the nanometer negative ion powder; (2)adding the stable dispersing liquid into a water-based adhesive, stirring at high speed, and emulsifying, so as to obtain an opened-pore water-based adhesive emulsion containing the nanometer negative ion powder; (3) adopting a gap type spot-spray flow technology, and performing scattering type spot-spray flow operation on the filtering substrate multiple times, so as to obtain the filtering substrate loaded with the nanometer negative ion powder; (4) curing the filtering substrate, so as to obtain the filtering material. The filtering material has the advantages that the immobilizing property is efficient, the load is not liable to fall off, and the release amount of ecological negative oxygen ions can reach 25000 per square centimeter.
