description The invention discloses an air purifying membrane and a preparation method thereof and belongs to the field of air purification. The preparation method of the air purifying membrane comprises the following steps of uniformly mixing sodium chloride, polytetrafluoroethylene and zinc naphthenate in water; uniformly mixing in manganese oxide, graphite powder, chlorinated polyethylene, calcium stearate, methyl vinyl phenyl silicone rubber and polyethylene wax, and then filtering out solution; melting the filter residues, and then performing extrusion and blown film molding. The preparation method of the air purifying membrane has the advantages that the polytetrafluoroethylene can improve the filtering efficiency of the air purifying membrane on particles of 0.02-10 mu m to achieve good hydrophobicity; the manganese oxide achieves a long-acting anion release function, therefore, filter materials can be stable and effectively purify air. 本发明公开了种空气净化膜及其制备方法，属于空气净化领域。该方法包括以下步骤：将氯化钠、聚四氟乙烯、环烷酸锌加入水中，搅拌均匀；加入氧化锰、石墨粉、氯化聚乙烯
