Abstract

The invention discloses a melt-blown polypropylene electret master batch which comprises the following components in parts by weight: 45-100 parts of polypropylene, 5-70 parts of an electret, 1-5 parts of a compatilizer, 0.01-1 part of an antioxidant, and 0.01-5 parts of an anti-ultraviolet agent. The invention also discloses a preparation method of the melt-blown polypropylene master batch material. The master batch has the following beneficial effects: polytetrafluoroethylene subjected to oxidation by ozone and surface modification by a coupling agent is used as an electret, polypropylene resin and corresponding auxiliaries are mixed in a melt blending granulation mode to obtain a melt-blown polypropylene electret master batch material, and a non-woven fabric fiber product produced fromthe master batch and a pure polypropylene raw material has the advantages of being obvious in electret effect, high in filtering efficiency, small in wind resistance and the like. The melt-blown polypropylene electret master batch and the preparation method thereof have the advantages of simplicity, quickness and cheapness, and are suitable for large-scale batch production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a melt-blown polypropylene electret masterbatch and a preparation method thereof. Background technique [0002] With the progress of human society and the development of industrialization, there are a lot of particulate matter, bacteria and viruses floating in the ambient air where people gather. These harmful substances can be suspended in the air for a long time, and the transportation distance is long, so it is harmful to human health and the atmospheric environment. Quality has a big impact. Studies have shown that the smaller the particle diameter, the deeper the entry into the respiratory tract, the particles with a diameter of 10 microns are usually deposited in the upper respiratory tract, and the particles below 2 microns can penetrate deep into the bronchioles and alveoli. After the fine particles enter the human body and enter the alveoli, they directly affe...
