Problems solved by technology

[0003] However, in daily life, with the complexity of the natural environment, human health is facing violations from various microbial viruses: including influenza virus, Mycobacterium chelonis, Staphylococcus aureus, Candida albicans and other biological viruses impact, and the existing melt-blown cloth with excellent filtration performance is far from meeting the human resistance to this type of biological virus

Abstract

The invention discloses antibacterial melt-blown cloth. The antibacterial melt-blown cloth comprises a polypropylene base material, and 0.01%-5% of nanoscale composite copper metal ions, 0.01%-5% of a dispersing agent and 0.01%-5% of a toughening agent are added into the polypropylene base material per unit weight. The invention further discloses a preparation method of the antibacterial melt-blown cloth. The preparation method comprises the steps of dispersing and mixing, hot melt extrusion, plasticizing and heat preservation, metering and distributing, mold extrusion, hot air traction, web forming, electrostatic electret making and rolling. Due to the fact that metal ions and bacterial cell walls achieve bacterial adsorption through the charge opposite attraction principle, the metal ions are released into the bacterial cell walls to achieve the bacterial killing performance; and the metal ions form oxides to catalyze water inside and outside bacteria to generate H2O2 oxidative destruction, so that cells die. The H1NI influenza virus resistant activity rate is greater than or equal to 93%, the mycobacterium chelonae inhibition rate is greater than or equal to 96%, the staphylococcus aureus inhibition rate is greater than or equal to 97%, and the candida albicans inhibition rate is greater than or equal to 93%.

Description

technical field [0001] The invention relates to the field of antibacterial and bactericidal, in particular to an antibacterial melt-blown cloth and a manufacturing method thereof. Background technique [0002] Melt blown cloth has good filterability, heat insulation and oil absorption, and is widely used in the fields of air purification, oil absorption wiping, and medical protection. Filtration is its most basic performance, mainly due to the use of porous structure and small round hole process performance. It can well block solid particulate matter. If electret treatment is added to increase the electrostatic performance, the filtration effect can also be improved. Generally, at a flow rate of 32L / min, the filtration efficiency of 0.3um particle size can reach 99%. [0003] However, in daily life, with the complexity of the natural environment, human health is facing violations from various microbial viruses: including influenza virus, Mycobacterium chelonis, Staphylococcu...
