Embodiment 1

[0026] A preparation method of antibacterial melt-blown non-woven fabric, comprising the following steps:

[0027] (1) Preparation of modified polypropylene non-woven fabric:

[0028]First, the polypropylene non-woven fabric was treated with oxygen plasma, the plasma power was 150W, and the treatment time was 400s. After the treatment, it was taken out. Then, the methanol solution of 4-vinylbenzyl glycidyl ether with a mass fraction of 5% was sprayed on the polyethylene. The surface of the acrylic non-woven fabric was grafted and modified by ultraviolet radiation technology by irradiating the polypropylene non-woven fabric with ultraviolet light. After 10 minutes of ultraviolet light irradiation, ultrasonic cleaning was performed with ethanol, and then the polypropylene non-woven fabric was placed in polyhexamethylene. In the aqueous solution of guanidine phosphate, the molar ratio of the 4-vinylbenzyl glycidyl ether to the polyhexamethylene guanidine phosphate is 1:1.2, and t...

[0034] A preparation method of antibacterial melt-blown non-woven fabric, comprising the following steps:

[0035] (1) Preparation of modified polypropylene non-woven fabric:

[0036] First, the polypropylene non-woven fabric was treated with oxygen plasma, the plasma power was 200W, and the treatment time was 300s. After the treatment, it was taken out, and then the methanol solution of 4-vinylbenzyl glycidyl ether with a mass fraction of 5% was sprayed on the polyethylene. The surface of the propylene non-woven fabric was grafted and modified by ultraviolet radiation technology by irradiating the polypropylene non-woven fabric with ultraviolet light. After 15 minutes of ultraviolet light irradiation, it was ultrasonically cleaned with ethanol, and then the polypropylene non-woven fabric was placed in polyhexamethylene. In the aqueous solution of guanidine phosphate, the molar ratio of the 4-vinylbenzyl glycidyl ether to the polyhexamethylene guanidine phosphate is 1:1.3, and...

Embodiment 3

[0042] A preparation method of antibacterial melt-blown non-woven fabric, comprising the following steps:

[0043] (1) Preparation of modified polypropylene non-woven fabric:

[0044] First, the polypropylene non-woven fabric was treated with oxygen plasma, the plasma power was 250W, and the treatment time was 200s. After the treatment, it was taken out, and then the methanol solution of 4-vinylbenzyl glycidyl ether with a mass fraction of 5% was sprayed on the polyethylene. The surface of propylene non-woven fabric is grafted and modified by ultraviolet radiation technology by irradiating polypropylene non-woven fabric with ultraviolet light. After modification, ultrasonic cleaning with ethanol is used, and then the polypropylene non-woven fabric is placed in polyhexamethylene guanidine. In the aqueous solution of phosphate, the molar ratio of the 4-vinylbenzyl glycidyl ether to the polyhexamethyleneguanidine phosphate is 1:1.5, and the reaction is refluxed at 50 ° C for 12 h...

Abstract

The invention relates to the technical field of non-woven fabrics, and provides a method for preparing an antibacterial melt-blown non-woven fabric, comprising the following steps: (1) performing oxygen plasma treatment on a polypropylene non-woven fabric, and then grafting and modifying it to obtain Modified polypropylene non-woven fabric; (2) using propylene diamine and methyl methacrylate as raw materials, polymerized into an amino-terminated hyperbranched polymer, and then through the polycondensation reaction of carboxymethyl chitosan and amino-terminated hyperbranched polymer The prepared modified hyperbranched polymer; (3) adding the cupric chloride solution to the modified hyperbranched polymer aqueous solution, dripping the sodium borohydride solution under nitrogen protection and ice bath conditions, and adding the modified polymer solution after the reaction. The propylene non-woven fabric is immersed in the modified hyperbranched polymer aqueous solution, and dried to obtain an antibacterial melt-blown non-woven fabric. The present invention solves the problem that the prior art melt-blown non-woven fabric has only high-efficiency filtering effect and no antibacterial property.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a preparation method of an antibacterial melt-blown non-woven fabric. Background technique [0002] Masks generally use SMS composite multi-layer structure, that is, the inner and outer layers are single-layer spunbond non-woven fabrics, the middle layer is a single-layer melt-blown non-woven fabric, or the middle layer is SMMS, a 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 haze to 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 thin stream of polymer melt extruded from the spinneret hole...
