| description | The invention belongs to the technical field of filtering materials, and particularly relates to a filtering material and a preparation method and application thereof. The filtering material of the invention comprises a fiber paper layer, a gelatin mixture layer and a polypropylene layer which are sequentially stacked, wherein the polypropylene layer is a polypropylene spun-bonded layer and/or a polypropylene melt-blown non-woven fabric layer, and the fiber paper layer, the gelatin mixture layer and the polypropylene layer are connected in a needling mode. According to the invention, the fiberpaper layer provides an air labyrinth filtering layer, so large particles in the air are blocked, and the air can smoothly pass through the air labyrinth filtering layer; the gelatin mixture layer has an open pore structure, is large in specific surface area and high in open porosity, so adsorption and capture of harmful particles in air by the filtering material are facilitated; and the polypropylene layer is the polypr |
