[0003] The existing melt-blown filter cloth is mostly used in the medical and health or filtration industry to isolate bacteria and viruses, but the contamination of bacteria and viruses during use and after use is not easy...

Abstract

The invention discloses an antibacterial filter fabric and a preparation method thereof, and relates to the technical field of melt-blown cloth. The antibacterial filter fabric is prepared from the following raw material components by weight: 80-90 parts of high-melt-index polypropylene, 4-8 parts of nano silver ion powder, 2-4 parts of PP electrostatic electret masterbatch, 1-3 parts of bamboo charcoal powder, 1-3 parts of nano titanium dioxide powder, and 0.6-0.8 part of a diffusant NNO. The melt index of the high-melt-index polypropylene is 1500. The antibacterial filtering fabric provided by the invention has the functions of efficiently adsorbing and removing bacteria and viruses, removing peculiar smell and self-cleaning. The preparation method of the antibacterial filtering fabric provided by the invention is simple to operate and stable in technology, and the prepared fabric is excellent in performance and extremely high in commercial value.
