Abstract

The invention relates to an anti-virus-pollution recyclable mask and a preparation method, and belongs to the technical field of medical equipment. The mask comprises a mask body and ear bands, and ischaracterized in that the mask body comprises an inner layer and an outer layer, the inner layer is a skin-friendly medical non-woven fabric layer and a filtering layer, the outer layer is a filtering isolation layer and an outer side layer, and an adsorption sterilization layer is further attached to the outer layer to form an antimicrobial layer to inhibit and kill pathogenic microorganisms (such as high-activity viruses) attached and adsorbed to the outer layer of the mask. The layers are located on the mask outer layer and the outer filtering layer, edible salt is safe, and the mask is harmless to the human body and free of toxic and side effects. Aiming at viruses (such as 2019 new coronavirus) with long in-vitro survival time and strong infectivity, the possibility of infection andpropagation caused by the viruses attached to the outer side of the medical mask is avoided; when epidemic situations are tense and the mask supply is short, the disposable mask can be safely and repeatedly used, equivalently, the mask productivity is increased, and good social benefits are achieved.

Description

technical field [0001] The invention relates to a mask, in particular to a recyclable anti-virus pollution mask and a preparation method, belonging to the technical field of medical equipment. Background technique [0002] When a virus mainly transmitted through the respiratory tract causes a large-scale epidemic, medical-grade masks or N95 personal protective masks become the most critical and commonly used public health supplies, such as the 2019 novel coronavirus (COVID-2019) incident. In general, ordinary viruses leave the host's living body and survive in nature for no more than 2 hours. Medical-grade masks can safely and effectively prevent viruses from invading the human body through the respiratory tract. However, the latest research on the 2019 new coronavirus shows that after the patient's cough, body fluids and feces spread the virus outside the body, the virus can survive for up to 24 hours! It has also been reported that the virus can survive for 48 hours on th...
