Abstract

The invention belongs to the field of mask protection, and particularly discloses a recyclable mask, a preparation method and a recycling method. The recyclable mask comprises mask fibers serving as a substrate and a highly-compact nano-film which is formed by complexing polyphenol metal and wraps the surface of the substrate. Compared with masks prepared by other improvement means such as adding an activated carbon layer and a graphene layer and installing an air filter, the mask does not change the original shape of the mask, normal wearing is not affected, meanwhile, the structure and components of original fibers of the mask are not changed, and the air permeability is also improved. Neither polyphenol nor metal ions can be fixed on the mask fibers independently, through compounding and two times of spraying, the polyphenol and the metal ions form a high-density nano-composite on the surface of the mask fibers, and the adhesivity and the antibacterial property of the nano-composite enable the mask to have higher particle interception efficiency and sterilization, antivirus and inactivation capabilities.

Description

technical field

[0001] The invention relates to the field of mask protection, in particular to a recyclable mask, a preparation method and a recycle method. Background technique

[0002] In the history of human development, global epidemics caused by severe bacteria and viruses have occurred from time to time, including SARS-CoV, MERS, and SARS-CoV-2 (Andersen K G , Rambaut A , Lipkin W I , et al. The proximal origin of SARS- CoV-2[J]. Nature Medicine, 2020, 26(4).), which is characterized by sudden outbreak, high infectivity, wide spread and strong lethality, causing huge losses to human health, economic development and even environmental protection .

[0003] In the face of acute infectious diseases, people can only trace the pathogens after the outbreak of the epidemic, so as to develop targeted vaccines, which is a passive defense; and the development of vaccines is difficult, requiring huge manpower, material and financial resources; from the outbreak of the epidemic t...
