Embodiment 1

[0020] exist figure 1 , figure 2 Among them, the raw materials used in this process include polymer material slices (polypropylene slices with a melt index of 1500g / (10min)), nano-silver antibacterial agents, electret additives (zinc stearate powder), polypropylene slices and 0.5% Zinc stearate is evenly mixed and enters the melt-blown equipment. The mixture passes through the screw extruder, melt 4 filter system, metering pump, and distribution system and then reaches the spinneret. The temperature of the five areas of the screw extruder ranges from 130°C to 250°C, the temperature of the melt 4 filtration system, metering pump, and distribution system is controlled at about 250°C; the melt 4 is ejected from the spinneret under pressure, and the hot air 3 is ejected from the spinneret 2 and melts the melt 4. Drafting, the temperature of the hot air 3 is 250°C, and the speed is about 300m / s; at this time, nano-silver particles with a particle size of 1-100nm are sprayed from ...

Abstract

The invention discloses an antibacterial low-resistance high-efficiency melt-blown non-woven fabric, which is prepared by the following steps: high polymer materials are sliced, particles of antibacterial agent are embedded onto the surface of polypropylene ultra-fine fibers in a powder spraying way in a melt spinning process, and an electret process treatment is carried out. The fabric has the characteristics that the process is simple, the operation is convenient, the antibacterial effect after treatment is obvious, and the like.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an antibacterial low-resistance high-efficiency melt-blown nonwoven fabric and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the air quality in cities is deteriorating day by day. As we all know, most Chinese people have turned pale when talking about PM2.5. Major media, forums, and famous sociologists 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 extremely small particulate matter floating in the air, PM2.5 belongs to it, specifically: fine suspended particles with a particle size range of 2.5 μm or less, and the unit is expressed in μg / m3. PM2.5 is only about 1 / 28 of the diameter of hair and 1 / 35 of the diameter of sand, so it can penetrate the alveoli...
