The invention relates to negative ion electrostatic dust removal paper and a preparation method thereof. The negative ion electrostatic dust removal paper comprises a base paper layer and a coating layer covering the surface of the base paper layer, wherein the coating layer is formed by coating and drying a coating liquid. According to the invention, the inorganic electret material and the polymer electret material are matched for use to prepare the coating liquid capable of meeting the coating requirement, and the coating liquid is coated on the surface of the base paper to prepare the negative ion electrostatic dust removal paper, so that the electret efficiency is better, the induced electrostatic voltage is higher, the electrostatic adsorption capacity is stronger, and the dust removal efficiency is higher. |
