Abstract

The invention provides an antibacterial low-barrier melt-blown non-woven fabric which is prepared from modified polypropylene, glass fiber, and graphene oxide sol. The modified polypropylene is formedby polymerizing polypropylene and N-(3-aminopropyl) acrylamide monomer, and the chemical structure is shown as a formula I. A preparation method of the antibacterial low-barrier melt-blown non-wovenfabric is simple, and the prepared melt-blown non-woven fabric has good antibacterial performance and low barrier performance, when the prepared melt-blown non-woven fabric is used in a water purifier, chloride ions can be freed under the action of water, a good sterilization effect is achieved, and the material can be used repeatedly after chlorine bleaching again, so that the service life of thematerial is prolonged.

Description

Technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to an antibacterial low-resistance melt-blown non-woven fabric and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the air quality in cities is also deteriorating. As we all know, most of the Chinese people have been talking about PM2.5. Major media, forums and famous social scholars have called for strengthening the control of air pollution. Various "PM2.5 forecasting platforms" are constantly updating the pollution index of cities across the country. [0003] Fine suspended particles are very small particles that are dispersed in the air. PM2.5 belongs to them. Specifically: fine suspended particles with a particle size range of 2.5μm and below, in μg / m 3 Said. PM2.5 is about 1 / 28 of the diameter of hair and 1 / 35 of the diameter of sand, so it can penetrate the alveoli and directly enter the blood vessels to circu...
