Abstract

The invention discloses an electret master batch material special for melt-blown cloth and a preparation method of the electret master batch material, and relates to the technical field of materials for melt-blown cloth production. The composite material is prepared from the following raw materials: polypropylene resin, an electret, a compatilizer, an antioxidant and a weather-proof agent, wherein the electret is prepared from the following components: tourmaline with the average particle size of 0.01 [mu]m-0. 05 [mu]m, polyethylene glycol and chitosan. The electret agent in the existing electret master batch material is modified, so that the melt-blown fabric produced by the electret master batch material has excellent electret durability, the expiration date of the melt-blown fabric and derived products thereof is prolonged, and the phenomenon that a die head is blocked by a machine in the melt-blown fabric production process is prevented.

Description

technical field [0001] The invention relates to the technical field of materials for the production of melt-blown cloth, in particular to a production process of special electret masterbatch materials for melt-blown cloth. Background technique [0002] Melt-blown cloth is the core material for mask production. Because of its many voids, fluffy structure, and good wrinkle resistance, the ultra-fine fibers with a unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has a good It is widely used in air and liquid filter materials, isolation materials, absorption materials, medical and industrial mask materials, thermal insulation materials, oil absorption materials and wiping cloths. [0003] Electret masterbatch is a special functional masterbatch used with electret equipment in the production process of meltblown cloth, which has the function of producing ions and storing charges. The melt-blown cloth will be ...
