The invention belongs to the field of
air cleaning, and especially relates to a novel filtering material for an
air cleaning machine, and a preparation method and a use thereof. The filtering material comprises at least one melt-blown fabric filter layer subjected to surface electrostatic treatment, and an
active carbon layer uniformly arranged on the at least one melt-blown fabric filter layer, and the outer side of the at least one melt-blown fabric filter layer is also provided with a
polyester skeleton supporting layer. The novel filtering material is an one body formed by sequentially bonding the
polyester skeleton supporting layer as a first layer, the melt-blown fabric filter layer as a second layer, the
active carbon layer as a third layer, the melt-blown fabric filter layer as a fourth layer and the
polyester skeleton supporting layer as a fifth layer, can realize efficient cleaning of
solid pollutants and gas pollutants, and can greatly reduce the volume of the filter core of the
air cleaning machine and improve the space
utilization rate; and the melt-blown fabric filter
layers are subjected to the surface electrostatic treatment, so the adsorption efficiency of pollutants is greatly improved under same conditions, and the air cleaning efficiency is improved.
