Problems solved by technology

These conventional medical and civilian masks generally purify the air by isolating fine particles, but sulfur dioxide and nitrogen oxides in the air cannot be removed by filtration or adsorption
Moreover, after wearing the mask for a period of time, bacteria will breed and cause secondary pollution.
Most of the existing technologies for removing nitrogen oxides are to add a catalyst layer to the mask, but this method mostly uses noble metal catalysts, which is expensive and potentially harmful to human health

Abstract

A method for preparing a mask with a filter insert and a zinc oxide quantum dot insert, which relates to the field of dust-proof technology. The mask is provided with ear straps, and a three-layer activated carbon fiber layer insert is provided between the inner and outer layers of the mask body. sheet and zinc oxide quantum dot insert, the zinc oxide quantum dot insert is a degreasing cotton gauze insert with water-soluble zinc oxide quantum dots, and its preparation method is: prepare zinc acetate solution; prepare potassium hydroxide ethanol solution; prepare zinc oxide quantum dot point; preparation of mask inserts; reload. The preparation method of the zinc oxide quantum dot insert of the present invention is simple, highly integrated, recyclable, has good smog protection and health care effects, and realizes the protection of sulfur dioxide and nitrogen oxides by masks without using noble metal catalysts. Filtration of toxic gases. The mask has certain antibacterial properties, and the inner and outer layers can be washed and reused repeatedly.

Description

technical field [0001] The invention relates to the field of dustproof technology, in particular to a mask with a filter insert and a method for preparing the zinc oxide quantum dot insert. Background technique [0002] The 2016 survey report on smog weather shows that 33 cities in my country have experienced severe pollution, and unprecedented severe smog weather has occurred, affecting people's health, life and travel. The main components of smog are inhalable particulate matter, sulfur dioxide and nitrogen oxides, and these three items, which mainly come from industrial production, coal burning, motor vehicles, and flying dust. Inhalable particles usually have a particle size of less than 10 um. When the particle size is less than 2.5 um, the human nose and throat cannot be filtered. These particles will enter the blood circulation system through the bronchi and alveoli, and damage the human respiratory system and cardiovascular system. After sulfur dioxide is inhaled in...
