Preparation method of all-synthetic fiber F9-grade air filtering material and product of all-synthetic fiber F9-grade air filtering material

The invention provides a preparation method of a fully synthetic fiber F9-grade air filtering material and a product, and the preparation method comprises the following steps: a, respectively taking raw materials of synthetic fiber and superfine fiber according to a weight ratio, adding water into the mixed raw materials, mixing, stirring and dispersing into slurry; b, preparing the slurry into a filter material according to an existing wet forming method; c, after the filter material is dehydrated, coating the acrylic resin liquid on the surface of the filter material; and d, enabling the filter material coated with the acrylic resin liquid to sequentially pass through three groups of drying cylinders, so that the water content of the dried filter material is less than 5%. The invention provides a novel filtering material for filtering and isolating germs in air, and the problem of African swine fever is effectively solved. 本发明提供了一种全合成纤维F9级空气过滤材料的制备方法及产品，制备方法包括如下步骤：a.按重量比分别取原料合成纤维及超细纤维，于混合原料中加入水，混合，搅拌分散成浆；b.
