Abstract

The invention discloses polypropylene resin for melt-blown fabric production and a preparation method thereof, and relates to the technical field of materials for melt-blown fabric production. The polypropylene resin is prepared from the following raw materials: polypropylene resin, a silver ion aqueous solution, waterborne aziridine, waterborne polyurethane, a compatilizer, a weather-proof agent and an antioxidant. The preparation method comprises the following steps: stirring and mixing raw materials in a stirrer to obtain a mixed material; putting the mixed material into a double-screw extruder for plasticizing extrusion, cooling to obtain a hardened material, granulating, sieving, cooling and drying. The melt-blown fabric has the effect of inhibiting the growth of bacteria and viruses, and solves the problem that the mask and other products made of the existing melt-blown fabric cannot be repeatedly used due to no effect of inhibiting the growth of bacteria and viruses, and therefore the resource waste is caused.

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 polypropylene resin for the production of melt-blown cloth. Background technique [0002] Meltblown cloth is the core material for mask production, and polypropylene is the main raw material for production. Because of its large voids, fluffy structure, and good wrinkle resistance, the ultrafine fibers with a unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filterability, shielding, heat insulation and oil absorption. It is widely used in air and liquid filter materials, isolation materials, absorbent materials, medical and industrial mask materials, thermal insulation materials, oil-absorbing materials and wiping cloths. [0003] However, although the existing melt-blown cloth plays an irreplaceable role with its excellent filtration pe...
