Preparation process of mask base material for killing and inactivating virus and germs and mask

Abstract

The invention relates to a preparation process of a mask base material for killing and inactivating virus and germs and a mask. The preparation process comprises the following steps that sodium chloride particles are pulverized into sodium chloride powder, and non-woven fabric is coated with the sodium chloride powder to prepare an antiviral and germs-resistant mask base material; or the non-wovenfabric is soaked in a sodium chloride solution, the sodium chloride solution is infiltrated into the non-woven fabric through ultrasonic oscillation, and the anti-virus and germs-resistant mask basematerial is prepared through drying and hot pressing. The mask is prepared from the antiviral and germs-resistant mask base material, so that the mask has the function of killing and inactivating thevirus and the germs; and the mask base material can kill and inactivate the virus and the germs larger than the virus in volume, greatly improves the protection performance and effect of the mask, issafe and harmless to human bodies, is low in cost, and is suitable for mass production.

Description

technical field [0001] The invention relates to a mask and a production process thereof, in particular to a method for manufacturing a mask for killing and inactivating viruses and germs, and an anti-virus and germs mask made by the method. Background technique [0002] Viruses and germs are extremely small. They often parasitize on dust particles or water vapor and other media, and then spread through the media. Therefore, blocking the spread of media can indirectly prevent the spread of viruses and germs. During flu season or outbreaks, people should wear masks when going to public places where there may be a lot of viruses and pathogenic bacteria. By using masks to filter and block media with viruses and bacteria, such as contaminated water vapor or dust or saliva and other bacteria or virus-contaminated media, the purpose of preventing respiratory infectious diseases is achieved. [0003] However, most of the current general-purpose masks can only play the role of isola...

Problems solved by technology

[0003] However, most of the current general-purpose masks can only play the role of isolating fine particles and antibacterial and antibacterial, and cannot effectively kill and inactivate viruses and bacteria, especially the disposable medical masks currently used in large quantities, which have a total of only three layers of structure , the outer and inner layers are water-blocking and anti-cracking protective layers, and the middle layer is a filter layer (filter element). In theory, the effective protection time is short, only 2-4 hours. In fact, after wearing the mask, its protective effect is constantly changing. Poor, the protective effect drops significantly after 2-4 hours

In addition, other masks such as antibacterial masks with inorganic nano-antibacterial materials as functional components, graphene antibacterial breathable and warm masks, nano-silver air filter antibacterial masks, dust-proof and antibacterial masks with chitosan multi-functional layers, filter layers Antibacterial masks that absorb chlorine dioxide and eucalyptus extracts, antibacterial and antibacterial spunlace non-woven masks, etc. These masks can only inhibit and resist bacterial invasion, and cannot kill and inactivate viruses and bacteria, so they will bring potential The risk of primary and secondary infection and transmission, and some inventions use certain chemical and traditional Chinese medicine reagents as sterilizing substances, which may cause respiratory discomfort to sensitive groups
