Abstract

The invention provides a nano-fiber window screen material in a multilayer lamination structure and a preparation method of same. The nano-fiber window screen material is characterized by including, in a successive arrangement from bottom to top, a mesh screen base material, a nano-fiber layer and a cover layer. Melt-connection points are formed on the upper surface of the nano-fiber layer through solvent electrostatic spraying technology; by means of a lamination method of thermal adhesion, the cover layer is adhered to the nano-fiber layer by means of the melt-connection points. The preparation method is simple in process and low in cost. The nano-fiber window screen material in the multilayer lamination structure is not less than 90% in filtering efficiency to particles being 0.008-2 [mu]m in size and is not more than 60 Pa in resistance pressure drop. The material has long service live and has great application prospect in the technical fields of indoor air purification and dust removal.

Description

technical field [0001] The invention belongs to the field of nanofibers, and relates to a method for compounding nanofiber window screen materials with a multilayer composite structure, in particular to form uniform fusion joints within a certain depth range on the surface of the nanofiber functional layer, thereby strengthening the nanofiber layer and covering protection The bonding fastness of the layers, and then use the thermal bonding composite method to make the gauze base material, the nanofiber functional layer and the covering layer form a three-layer composite structure with a certain pattern. Background technique [0002] In recent years, the smog pollution problem that continues to appear in most parts of my country has seriously threatened people's health. Opening windows for ventilation and indoor cleanliness in a smog environment have become contradictory. Existing anti-smog window screens generally have low filtration efficiency. , nanofibers have structural c...
