Degradable antiviral melt-blown cloth and preparation method and application thereof

The invention relates to the field of medical instruments, in particular to the technical field of medical health protection, and particularly relates to degradable antiviral melt-blown cloth as well as a preparation method and application thereof. The degradable anti-virus melt-blown fabric is prepared by mixing the degradable anti-virus master batch and the electret master batch in a high-speed mixer and then melting, filtering and melt-blowing through melt-blown non-woven fabric production line equipment, the preparation method is simple and convenient, the raw materials are wide in source and low in price, and stable batch production can be achieved; the gram weight is 25-27 g/m < 2 >, the pressure difference is 18-22 Pa, the transverse breaking strength is 8-10 N, the longitudinal breaking strength is 8-11 N, the transverse elongation at break is 35-40%, the longitudinal elongation at break is 20-26%, the particle filtering efficiency is greater than 98%, the bacteria filtering efficiency is greater than
