Abstract

The invention provides a multifunctional air purification filter screen and a preparation method thereof. In this method, the cation exchange resin and the anion exchange resin are respectively formulated into a spinning liquid, and tourmaline and cerium dioxide powder are added to the spinning liquid for dispersion, and then composite spinning is carried out to make a nanofiber non-woven fabric, and further passed The solvothermal reaction generates zinc cadmium sulfide photocatalyst in situ and loads it on the surface of non-woven fabric to prepare multifunctional air purification filter. Compared with the traditional method, the air purification filter prepared by the present invention can remove NH in the air by ion exchange adsorption 3 , NO 2 , SO 2 , SO 3 , HF, HCl, H 2 Inorganic gases such as S, remove PM2.5 particles in the air through physical and chemical adsorption, and catalyze the degradation of formaldehyde, benzene, toluene and other volatile organic compounds in the air through zinc cadmium sulfide, and can also release negative oxygen ions, and the structure is simple and low cost. Low.

Description

technical field [0001] The invention belongs to the technical field of air purification materials, and provides a multifunctional air purification filter screen and a preparation method. Background technique [0002] With the increasing environmental pollution, air pollution has become an important issue that threatens human health and social development in today's world.
