Embodiment 1

[0031] An antibacterial non-woven fabric, the raw material of the antibacterial non-woven fabric comprises the following components by weight: 75-100 parts of polypropylene, 10-25 parts of sodium styrene sulfonate, 10-20 parts of silane coupling agent, polyhexa 0.15-1 part of methylene biguanide hydrochloride, 0.05-0.4 part of zinc salt, 1-5 parts of bamboo charcoal fiber, and 0.01-0.1 part of nano-scale fumed silicon dioxide.

[0032] Specifically, polyhexamethylene biguanide (PHMB) has a broad spectrum of sterilization, low effective concentration, fast action speed, stable properties, high-quality properties of being easily soluble in water, can be used at room temperature, long-term antibacterial, no side effects, no Corrosive, colorless, odorless, non-toxic, non-flammable, non-explosive, safe to use, it is the best fungicide in practice. Bactericidal effect of polyhexamethylene biguanide: 0.02% polyhexamethylene biguanide has a 100% sterilization rate against Escherichia ...

Embodiment 2

[0036] The invention also discloses a preparation method of antibacterial non-woven fabric, comprising the following steps:

[0037](1) Weighing: Weigh the following components by weight: 75-100 parts of polypropylene, 10-25 parts of sodium styrene sulfonate, 10-20 parts of silane coupling agent, 0.15 parts of polyhexamethylene biguanide hydrochloride ~1 part, 0.05~0.4 parts of zinc salt, 1~5 parts of bamboo charcoal fiber, 0.01~0.1 part of nano-scale fumed silica;

[0038] (2) Heat the weighed polypropylene, sodium styrene sulfonate, and silane coupling agent aqueous solution in a water bath to 60±2°C, keep warm and stir for 2.5±0.5h, then irradiate with ultraviolet rays for 15±2min and then cool down to 25±2°C to obtain a polypropylene mixture;

[0039] (3) The polyhexamethylene biguanide hydrochloride, zinc salt that weighs is adopted the aqueous solution reaction method to make complex solution, then adds nanoscale fumed silicon dioxide to obtain composite antimicrobial a...

Embodiment 3

[0051] like Figure 1~4 As shown, the present invention also discloses a mouth mask with antibacterial non-woven fabric, comprising a mouth mask body 1, a mask belt 2, and a nose strip 3, and the mouth mask body 1 includes at least one antibacterial non-woven fabric layer 11, at least one The filter cloth layer 12 of layer, described antibacterial non-woven fabric layer 11 is bonded with filter cloth layer 12, and described filter cloth layer 12 is arranged far away from face, and antibacterial nonwoven fabric layer 11 is arranged near face; Described mouth mask belt 2 is arranged It is on the side of the mask body 1, and is used to closely fit the mask body 1 to the face; the nose strip 3 is arranged on the top of the mask body 1, and is used to closely fit the mask body 1 to the bridge of the nose; the antibacterial nonwoven The material of cloth layer 11 is the antibacterial non-woven fabric described in claim 1.

[0052] Preferably, the mask straps 2 are arranged on both ...

Abstract

The invention discloses an antibacterial non-woven fabric. The antibacterial non-woven fabric is prepared from, by weight, 75-100 parts of polypropylene, 10-25 parts of sodium p-styrenesulfonate, 10-20 parts of a silane coupling agent, 0.15-1 part of polyhexamethylene biguanidine hydrochloride, 0.05-0.4 part of zinc salt, 1-5 parts of bamboo charcoal fibers and 0.01-0.1 part of nanoscale fumed silica. The invention also discloses a preparation method of the antibacterial non-woven fabric and a mask with the antibacterial non-woven fabric. The antibacterial non-woven fabric prepared by the preparation method is processed into an antibacterial non-woven fabric layer of a certain size to be applied into the mask for concentratedly resisting bacteria, filtering out dust particles and preventing air from passing through gaps, so that no air circulation occurs, and the effect is promoted from the structural layer that air passes through all layers of a mask body for sterilization and filtering and then enters the mouth and the nose, and the prevention effect is accordingly achieved by preventing bacteria from spreading through the air and the saliva.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to an antibacterial nonwoven fabric, a preparation method thereof and a mask with the antibacterial nonwoven fabric. Background technique [0002] With the aggravation of environmental pollution in modern society, air pollutants are mainly divided into harmful gases and particulate matter. At present, there are more than 100 known air pollutants. There are two kinds of natural factors and human factors, and the latter is the main factor, especially the pollution caused by industrial production and transportation. [0003] Smog is an aerosol system formed by water vapor and particulate matter in the atmosphere. Atmospheric particulate matter refers to a multiphase system mixture composed of solid or liquid particles suspended in the air. The sources of atmospheric particulate matter are mainly divided into two categories: natural channels and human activities; natural dust...
