Abstract

The invention relates to a multi-functional reusable mask for efficient filtration and adsorption sterilization and a preparation method thereof. The mask comprises a first supporting layer, a multi-functional layer and a second supporting layer which are arranged in a stacked mode, and the multi-functional layer is a silver ion doped titanium dioxide coated attapulgite-oxide nanofiber layer. Thepreparation method of the nanofiber layer comprises the following steps of: firstly, mixing oxide precursor sol, water and a spinning aid, and then carrying out electrostatic spinning and high-temperature sintering to obtain an oxide nanofiber layer; then mixing attapulgite with water, treating the mixture by a cell crusher, and mixing the mixture with silver ion doped titanium dioxide sol to obtain a spraying liquid; and finally, spraying the spraying liquid on the oxide nanofiber layer, and carrying out heat treatment to obtain the nanofiber layer. Compared with the prior art, the mask has the advantages of comfort, air permeability, simple preparation method and the like, can meet the requirements of multiple functions such as adsorption, filtration, visible light degradation sterilization and the like, and has a wide commercial application prospect.

Description

technical field [0001] The invention belongs to the technical field of health protection products, and relates to a multifunctional reusable mask for high-efficiency filtration, adsorption and sterilization and a preparation method thereof. Background technique [0002] Air pollution includes toxic and harmful gases, suspended particles, and biological air pollutants such as bacteria and viruses. At present, air pollution can cause severe respiratory diseases, heart disease and lung diseases through the respiratory tract, and has become an important factor that endangers human health. Therefore, doing a good job in personal protection is a necessary way to reduce the harm caused by air pollution to the human body (Guidelines for Health Protection of People with Air Pollution (Haze), compiled by the General Office of the National Health Commission). However, indoor air environment purification systems are expensive and cannot meet the needs of outdoor travel. Wearing a mask...
