Problems solved by technology

[0005] The invention provides a special electret masterbatch material for melt-blown cloth and a preparation method thereof. The electret masterbatch material prepared by the method solves the problem that the electret masterbatch obtained from the production of the existing inorganic electret agent is difficult to produce melt-blown cloth. The link is easy to make the meltblown cloth machine block the die head, and it is often necessary to change the screen every 2 to 3 hours

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 ...
