Problems solved by technology

However, the existing mask materials cannot effectively intercept particles and kill bacteria. They have a certain protective effect on particles and bacteria in a specific environment, but at the same time there are many shortcomings, such as thick fiber diameters and ultrafine fiber diameters. Low filtration efficiency of particulate matter

Abstract

The invention provides a traditional Chinese medicinal antibacterial mask containing a graphene oxide-copper silver nanocomposite. A middle layer of the mask is medical woven fabric which adsorbs an antibacterial and anti-inflammatory medicinal liquid, and the medicinal liquid comprises the following preparing raw materials: the graphene oxide-copper silver nanocomposite, scutellaria baicalensis,clove, white atractylodes rhizome, cordate houttuynia, agastache, folium artemisiae argyi, herba eupatorii, flos inulae, flos magnoliae, gardenia, cocklebur, schizonepeta and coptis chinensis; an outer layer of the mask is a PM2.5 particle filtering layer, the outer layer and an inner layer are connected through a zipper on one sides, and the middle layer is detachable. The traditional Chinese medicinal antibacterial mask has a certain effect of filtering and sterilizing air entering the lung; in case of an epidemic respiratory infectious disease, during working in an environment polluted by dust and the like, or on hazy days, wearing of the mask has an extraordinary protective effect.

Description

technical field [0001] The invention relates to a mask, in particular to a traditional Chinese medicine antibacterial mask. Background technique [0002] In recent years, smog has become the primary problem of air pollution in my country. The smog contains a large amount of toxic and harmful particles, which seriously damage the human respiratory system and cardiovascular system, leading to an increase in the incidence of asthma, bronchitis, myocardial infarction and other diseases, and have a great impact on people's lives. At the same time, harmful bacteria in the air are ubiquitous, including diplococcus, monococcus, sarcina, tetrad, staphylococcus, etc., with fast reproduction speed, strong survivability, and wide spread. When spreading in the air, causing Many diseases, such as influenza, tuberculosis, measles, mumps, whooping cough, diphtheria, etc., are highly contagious and harmful. Therefore, there is an urgent need for an effective means that can filter out dust ...
