Problems solved by technology

Although the mask achieves the effect of sterilizing and killing viruses through lysozyme, it is limited by the activity of lysozyme, and the antibacterial and antiviral time of the mask is shorter
[0005] (2) There is a risk of secondary infection after wearing the mask
The mask can filter particles above 100nm, and can finely filter viruses and bacteria, but does not kill bacteria and viruses, and there is a risk of secondary infection after wearing the mask

Abstract

The invention relates to an antibacterial and antiviral mask and a preparation method thereof. The antibacterial and antiviral mask sequentially comprises an antibacterial layer, a bacteria dissolvinglayer and an antiviral layer from outside to inside, wherein the antiviral layer comprises aminopeptidase, and the aminopeptidase is derived from streptomyces nitro. According to the antibacterial and antiviral mask, aminopeptidase from streptomyces nitro is selected as an antiviral agent, so that the antibacterial and antiviral mask has the advantages of being high in antiviral property, safe and environmentally friendly; the antibacterial and antiviral mask has lasting antibacterial and antiviral capacity, the antibacterial and antiviral effects are thorough, and secondary infection of bacteria and viruses is effectively avoided; and the preparation method of the antibacterial and antiviral mask has the advantages of simplicity in operation, low cost, easiness in implementation, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of daily protective products, in particular to a mask, in particular to an antibacterial and antiviral mask and a preparation method thereof. Background technique [0002] Respiratory tract infectious diseases can be transmitted through the air and droplets, which can easily lead to concentrated infection of large-scale populations. Cutting off the transmission of pathogenic bacteria is an effective means to protect the health of the population. In 2007, the U.S. Centers for Disease Control and Prevention issued interim guidelines strongly recommending that people wear masks during flu outbreaks. In the event of a bacterial or viral outbreak, many countries have stockpiled protective masks as a means of non-pharmaceutical intervention to control the spread of the virus. With the outbreak of novel coronavirus pneumonia worldwide, people's demand for protective masks is increasing, especially the strong deman...
