Abstract

The invention discloses a mouth mask with a filtering insertion piece and a preparation method for the zinc oxide quantum dot insertion piece, and relates to the technical field of dust prevention. The mouth mask is provided with ear hanging belts; an active carbon fiber layer insertion piece adopting a three-layer structure and the zinc oxide quantum dot insertion piece are arranged between inner and outer layers of a mouth mask body; and the zinc oxide quantum dot insertion piece is an absorbent cotton gauze insertion piece with water-soluble zinc oxide quantum dots. The preparation method comprises the steps of preparing a zinc acetate solution; preparing a potassium hydroxide ethanol solution; preparing the zinc oxide quantum dots; preparing the insertion piece of the mouth mask; and performing reloading. The zinc oxide quantum dot insertion piece is simple and convenient in preparation method, is high in integration and recyclable, and has good haze protection and healthcare effects; and the filtration of the mouth mask for toxic gases such as sulfur dioxide, nitric oxide and the like is realized without use of a noble metal catalyst. The mouth mask has a certain antibacterial performance, and the inner and outer layers can be repeatedly washed and repeatedly used.

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...
