Abstract

The invention relates to the technical field of medical materials, and provides a preparation method for an antibacterial and antiviral protective material. The preparation method for the antibacterial and antiviral protective material comprises the steps of (1) adding polyvinyl alcohol and polylysine into de-ionized water of 90 to 100 DEG C, stirring and dissolving to prepare a solution A with the mass fraction of 8 to 12 percent; (2) dissolving a natural plant extracting liquid, a softening agent, and an emulsifying agent into an organic solvent to prepare a solution B; (3) slowly adding thesolution B to the solution A, and after the solution B is added completely, continuing stirring for 20 to 40 minutes to obtain a stable emulsion; and (4) performing electronic spinning on the emulsion obtained in the step (3) to prepare a protective material for isolating viruses or bacteria. The preparation method for the antibacterial and antiviral protective material solves the problems that the medical protective material in the prior art can only isolate the bacteria and the viruses, and does not have the functions of resisting the bacteria and germs.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a preparation method of an antibacterial and antiviral protective material. Background technique [0002] Clinical medical staff are easily exposed to patients' blood, body fluids, secretions and other potentially infectious substances during work. Wearing medical protective clothing can provide barrier and protection and reduce the risk of cross-infection. Medical protective clothing is often made of spunbond-meltblown-spunbond composite nonwovens (ie SMS composite nonwovens). When droplets containing germs approach the meltblown nonwovens, they will be electrostatically adsorbed on the meltblown nonwovens. The surface of the woven fabric is impenetrable, thus playing the role of isolating germs. However, melt-blown non-woven fabrics do not have antibacterial and anti-virus functions. The intercepted germs reside on the surface of melt-blown non-woven fabrics, and vir...
