Mask capable of efficiently preventing haze and organic pollutants and preparation method of mask

Abstract

The invention discloses a preparation method of a mask capable of efficiently preventing haze and organic pollutants. The preparation method comprises the following steps: by adopting the electrospinning technology, firstly preparing a Fe<3+> and N codoped titanium dioxide micro / nano-fiber microporous membrane and a biomass high-polymer micro / nano-fiber microporous membrane, and carrying out appropriate assembling by adopting the two microporous membranes as the base materials, thus forming the mask capable of effectively blocking PM2.5, capable of resisting bacteria and capable of efficiently processing organic pollutants. From inside to outside, the mask sequentially comprises a biomass high-polymer melt-blow non-woven fabric layer, a biomass high-polymer micro / nano-fiber microporous membrane layer, the Fe<3+> and N codoped titanium dioxide micro / nano-fiber microporous membrane layer, the biomass high-polymer micro / nano-fiber microporous membrane layer and a polypropylene melt-blow non-woven fabric layer. The preparation method has the advantages that the technology and the device are simple, stable and reliable, the operation is convenient, and the prepared mask has the potential ability of being applied in the fields of daily going-out, laboratories and medical treatment. The technology is simple and feasible, and the application range is wide.

Description

technical field [0001] The invention relates to a mask, in particular to a highly effective anti-smog and organic pollutant mask and a preparation method thereof. Background technique [0002] The "Green Paper on Climate Change: Report on Climate Change (2013)" (hereinafter referred to as the "Green Paper") jointly issued by the Chinese Academy of Social Sciences and the China Meteorological Administration pointed out that China's haze weather has generally shown an increasing trend in the past 50 years. Among them, the number of foggy days decreased significantly, the number of hazy days increased significantly, and the process of persistent haze increased significantly. According to the green paper, the main reason for the increase of smog weather in China is the gradual increase in the emission of air pollutants caused by the increase in the consumption of petrochemical energy in society. The main sources of these pollution are thermoelectric emissions, industrial especi...

AI Technical Summary

Problems solved by technology

The so-called anti-smog mask, its protection against smog and the catalytic efficiency of organic pollutants therein are generally lower than 10%, even some as low as 1.1%, and some masks themselves contain toxicity, causing direct damage to the human body

The quality problems of anti-smog masks are very prominent, which makes the industry worry
