Embodiment 1

[0026] A preparation method for an antibacterial melt-blown nonwoven fabric, comprising the following steps:

[0027] (1) Preparation of modified polypropylene nonwoven fabric:

[0028]First, the polypropylene non-woven fabric is subjected to oxygen plasma treatment, the plasma power is 150W, and the treatment time is 400s. After the treatment, it is taken out, and then the methanol solution of 4-vinylbenzyl glycidyl ether with a mass fraction of 5% is sprayed on the polypropylene. The surface of the propylene non-woven fabric is grafted and modified by irradiating the polypropylene non-woven fabric with ultraviolet light using ultraviolet radiation technology. After 10 minutes of ultraviolet light irradiation, it is cleaned with ethanol ultrasonically, and then the polypropylene non-woven fabric is put into polyhexamethylene In the aqueous solution of guanidine phosphate, the molar ratio of 4-vinylbenzyl glycidyl ether to polyhexamethylene guanidine phosphate is 1:1.2, reflux...

Abstract

The invention relates to the technical field of non-woven fabrics, and provides a preparation method for an antibacterial melt-blown non-woven fabric. The preparation method comprises the following steps of (1) carrying out oxygen plasma treatment on a polypropylene non-woven fabric, and carrying out graft modification on the polypropylene non-woven fabric to prepare a modified polypropylene non-woven fabric; (2) polymerizing an amino-terminated hyperbranched polymer with propylene diamine and methyl methacrylate as raw materials, and preparing a modified hyperbranched polymer through polycondensation of carboxymethyl chitosan and the amino-terminated hyperbranched polymer; and (3) adding a copper chloride solution into a modified hyperbranched polymer aqueous solution, dropwise adding a sodium borohydride solution under nitrogen protection and ice bath conditions, carrying out impregnation treatment on the modified polypropylene non-woven fabric in the modified hyperbranched polymer aqueous solution after the reaction is finished, and drying to obtain the antibacterial melt-blown non-woven fabric. The preparation method solves a problem that the melt-blown non-woven fabric in theprior art only has an efficient filtering effect and does not have antibacterial property.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a method for preparing antibacterial melt-blown non-woven fabrics. Background technique [0002] The mask generally adopts SMS composite multi-layer structure, that is, the inner and outer layers are single-layer spunbond non-woven fabric, the middle layer is single-layer melt-blown non-woven fabric, or the middle layer is SMMS, which is multi-layer melt-blown non-woven fabric. SMMMS composite multilayer structure. The key to the filtering effect of the mask lies in the melt-blown non-woven fabric in the middle layer, which can filter micron-sized particles such as dust, microorganisms, and smog, and prevent the spread of germs. [0003] Melt-blown non-woven fabrics are made of polypropylene with high melt index as the main raw material, melted by high-pressure hot air flow, and then use high-speed hot air to draw the polymer melt stream extruded from the spinneret hol...
