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.

Description

technical field [0001] The invention relates to the technical field of meltblown cloth, in particular to an antibacterial filter fabric and a preparation method thereof. Background technique [0002] The fiber diameter of the existing melt-blown filter cloth can reach 1-2μm, and the arrangement is randomly distributed, with a certain degree of disorder. This structure makes it have a larger specific surface area and smaller pore size, which can be used as a high-quality Filter materials are mainly used in air filtration, water filtration, oil filtration, oil-water separation and many other fields. Through electrostatic electret treatment, its effect is better as a filter material. [0003] Existing melt-blown filter cloths are mostly used in medical and health care or in the filtration industry to isolate bacteria and viruses, but the contamination of bacteria and viruses during use and after use is not easy to control. In the medical industry, melt-blown cloth is often us...
