▎ 摘　　要

NOVELTY - A medical antibacterial composite mask comprises a skin-friendly inner layer, a negative ion oxygenation layer, an isolation filter layer and an antibacterial outer layer. The negative ion oxygenation layer and the isolation layer are arranged between the skin-friendly inner layer and the antibacterial outer layer. The negative ion oxygenation layer is provided between the skin-friendly inner layer and the isolation filter layer. The negative ion oxygenation layer includes 15.30-18.50% polypropylene anion fiber, 7.20-8.10% honeysuckle, 6.50-7.30% cloves, 6.30-6.90% oregano, 0.64-0.96% of nano anion powder, 0.64-0.96% of cellulose nanofibers, 0.56-0.84% nickel foil supports three-dimensional porous nickel film and balance of organic short fiber. USE - Medical antibacterial composite mask. ADVANTAGE - The medical antibacterial composite mask can effectively improve the antibacterial and oxygen supply effects of medical masks, so that normal people can feel only slightly unsatisfactory breathing under fast running, which can be effectively applied to the normal use of people with unsmooth breathing and reduce the feeling of stuffiness. The combination of nano anion powder and polypropylene anion fiber can enhance the oxygen concentration in the mouth and nose of the user, thereby ensuring the user's breathing smoothly. The combination of honeysuckle, clove and oregano can improve the antibacterial effect of medical masks. The nickel foil loaded three-dimensional porous nickel film can be used as a carrier for the effective ingredients of various other raw materials to ensure the antibacterial effect of medical masks and the effect of improving the oxygen concentration around the mouth and nose. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the medical antibacterial composite mask, which involves weighing the polypropylene anion fiber, honeysuckle, clove, oregano, nano anion powder, cellulose nanofiber, nickel foil supported three-dimensional porous nickel film and organic short fiber, grinding the honeysuckle, cloves and oregano into powder, mixing and adding 95% ethanol solution, sealing, infiltrating, heating and preserving heat for 5-6 hours, adding the mixture to a high-speed centrifuge for centrifugal filtration to obtain filtrate (A) and filter residue (B), sealing and storing for later use, adding five times the weight portion of deionized water to the filter residue (B), and decocting for 3-4 hours, filtering to obtain filtrate (C), mixing the filtrate (A) and the filtrate (C), and adding the nano anion powder, nickel foil loaded with three-dimensional porous nickel film and polypropylene anion fibers and cellulose nanofibers, heating and stirring and ultrasonically vibrating for 3-4 hours to obtain an antibacterial composite slurry, mixing the organic short fibers with the remaining polypropylene anion fibers and cellulose nanofibers to form a web and hot pressing to form a non-woven fabric for use, placing the non-woven fabric into the antibacterial composite slurry, and after soaking for 30-40 minutes, to obtain the antibacterial non-woven fabric, in which during the immersion process, ultrasonic vibration treatment is performed, and the remaining antibacterial composite slurry is electrostatically sprayed on both sides of the antibacterial non-woven fabric to obtain anion oxygen-enhancing layer, and placing the skin-friendly inner layer, negative ion oxygenation layer, isolation filter layer and antibacterial outer layer and placing the bridge of the nose and the elastic ear hooks in the corresponding positions and heat-pressing and shaping.
