Abstract

The invention relates to an electret master batch as well as a preparation method and application thereof. The electret master batch is prepared from the following raw materials in percentage by mass: 50%-80% of polypropylene resin, 3%-5% of an antibacterial agent, 5%-15% of an electret and 0.05%-36.5% of an auxiliary agent. The antibacterial agent is added into the electret master batch, and the antibacterial agent and the electret in a specific ratio have a synergistic effect, so that the electret master batch has an antibacterial effect while having relatively high filtering efficiency and relatively low respiratory resistance. Particularly, air mixed with viruses can be effectively filtered, and the viruses are prevented from passing through.

Description

technical field [0001] The invention relates to the technical field of melt-blown non-woven fabrics, in particular to an electret masterbatch and a preparation method and application thereof. Background technique [0002] In fields such as air purification, filter materials are needed to isolate particles, bacteria and viruses from people. Melt-blown non-woven fabrics are one of the key materials, and electret masterbatches are a key component of melt-blown non-woven fabrics. [0003] CN111560140A discloses a special organic electret masterbatch for melt-blown non-woven fabrics for masks and its preparation method, and the melt-blown non-woven fabrics made, said electret masterbatch includes components calculated by the following weight percentages: 80-90% polypropylene resin, 2-10% fluorine-based electret powder, 1-10% compatibilizer, and 0.05-0.5% processing aid. The average particle size of the fluorine-based electret powder is 0.05-3um, and the compatibilizer is an olef...
