Abstract

The invention belongs to the field of public environmental protection and health, and concretely relates to a mouth mask filter disc for efficiently purifying air, and a preparation method thereof. The preparation method comprises the following steps: (1) dissolving tetraisopropyl titanate and tin tetrachloride in anhydrous ethanol, adding ammonium fluoride and a ZIF-8 material, performing ultrasonic dispersion, and carrying out a sealing reaction to obtain an intermediate product A; (2) dispersing polyepichlorohydrin-dimethylamine water, adding the intermediate product A, performing ultrasonic treatment, adding polyol and glyceryl ether to obtain a reaction mixture, dropwise adding a precipitant, filtering the obtained solution, and adding an organic solvent to obtain a composite fiber stock solution; (3) electrospinning the composite fiber stock solution to obtain composite fibers, and weaving the composite fibers to obtain the mouth mask filter disc. Tin-fluorine co-doped titanium dioxide is generated in the pores of the ZIF-8 material in an in-situ manner by introducing tetraisopropyl titanate, tin tetrachloride and ammonium fluoride into the ZIF-8 material, so harmful substances in air are adsorbed and catalytically degraded in order to achieve the purpose of efficiently purifying the air.

Description

technical field [0001] The invention belongs to the field of public environmental protection and sanitation, and in particular relates to a mask filter for efficiently purifying air and a preparation method thereof. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, people's demand for energy is also increasing, especially in large and medium cities, all kinds of vehicles have increased significantly. Due to the lack of sufficient awareness and attention to the air pollution caused by these factors, in recent years, smog has occurred in densely populated areas, especially large and medium-sized cities, seriously threatening people's health and lives. [0003] Air pollution can not only have a destructive effect on surrounding objects through physical, chemical, and biological erosion, but also pollute our respiratory system, nervous system, immune system, skin, etc. through the human respiratory syst...
