Abstract

The invention discloses antibacterial melt-blown cloth as well as a preparation method and application thereof, and belongs to the technical field of melt-blown cloth production. The antibacterial melt-blown cloth comprises a polypropylene layer. The polypropylene layer is prepared from the following raw materials in parts by mass: 70-90 parts of polypropylene, 5-15 parts of maleic anhydride grafted polypropylene and 15-35 parts of antibacterial master batches. The antibacterial master batches are obtained by mixing, cooling and cutting polypropylene, a silver-zinc phosphate glass material, graphene and an auxiliary agent; and the use amount of the silver-zinc phosphate glass material accounts for 0.5-1% of the total mass of the polypropylene layer, the use amount of the graphene accountsfor 2-8% of the total mass of the polypropylene layer, and the use amount of the auxiliary agent accounts for 0.1-5% of the total mass of the polypropylene layer. The melt-blown cloth has the advantages that the antibacterial property is effectively enhanced, and the lasting antibacterial effect is realized.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth production, and more specifically relates to an antibacterial melt-blown cloth and its preparation method and application. Background technique [0002] Melt-blown cloth is made of polypropylene as the main raw material, and the high-speed hot air flow is used to draw the melt stream extruded from the spinneret hole of the die head to form ultra-fine fibers and collect them on the condensing screen or roller. Bonded to become a non-woven fabric. It has many voids, fluffy structure, good filterability, shielding, heat insulation and oil absorption; it can be used as filter material, isolation material, absorption material and other fields. [0003] When melt-blown cloth is used as a mask filter material, in order to ensure its sterilization and filtration effect, electrostatic electret is usually required; however, the electrostatic adsorption sterilization effect is not long-lasting, and...
