The invention relates to an antibacterial and antiviral melt-blown cloth and a preparation method thereof, which consists of the following raw materials in parts by weight: 100 parts of polypropylene particles with a melt index of 1500, 1-5 parts of electret masterbatch, and 0.03- parts of an antibacterial and antiviral agent 10 parts, lubricant 0.1-2 parts, dispersant 0.2-2 parts, heat stabilizer 0.1-0.2 parts. The preparation method of the meltblown cloth comprises the following steps: step (1) pretreatment of antibacterial and antiviral agent, step (2) mixing of raw materials, step (3) melt blowing, and step (4) physical property test. By adding lubricants, dispersants and thermal stabilizers, the antibacterial and antiviral agents are uniformly dispersed in the polypropylene particles to improve the thermal stability and dispersibility of the antibacterial and antiviral agents, so that they do not decompose during processing and use, and have excellent properties. It has excellent antibacterial and antiviral effects and high biosafety performance, and adopts the preparation process of direct melt-blown molding, which simplifies the operation process, reduces production costs, and is suitable for large-scale production. |
