The invention relates to a super-infiltration antiviral protective
mask and a preparation method thereof, the inner side of a
skin-friendly layer is coated with a nano adsorption disinfection super-hydrophilic protective
coating, and the outer side of an antibacterial layer is coated with a nano super-droplet-resistant antiviral super-hydrophobic protective
coating; the nano super-droplet-resistant antiviral super-hydrophobic protective
coating is prepared from the following components: a polar group
fluoropolymer, water-based
fluorocarbon resin, inorganic nanowires, tetraethoxysilane, absolute ethyl
alcohol and
ammonia water, the inner side surface nano adsorption disinfection super-hydrophilic protective coating comprises the following components:
chitosan quaternary ammonium salt and waterborne
polyurethane resin. Due to the fact that the outer side face of the
mask is coated with the nanometer super-anti-droplet antiviral super-hydrophobic protective coating, adhesion of
virus-containing droplets can be strongly repelled in a long-acting mode; due to the fact that the inner side face of the
mask is coated with the nanometer adsorption disinfection super-hydrophilic protective coating, the nanometer adsorption disinfection super-hydrophilic protective coating has extremely
high surface energy and extremely strong
electrostatic adsorption effect, adsorbed viruses and droplets are in full-spreading contact, and the inactivation rate of antibacterial
active matter on the viruses is greatly increased.
