Description
Technical field
The present invention relates to field of nonwoven fabric technology, and in particular to a kind of preparation method for non-woven fabrics antibacterial agent.
Background technique
Medical mask is made of mouthpiece surface body and puller strap, wherein mouthpiece surface body be divided into, in, it is three layers outer, internal layer be parent
Skin material, middle layer are isolation filter layer, and outer layer is the antibacterial layer of special material.This efficient medical mask hydrophobic, air-permeability is strong, right
The small filter effect with Virus Aerosol or harmful micronic dust is significant but cannot effectively filter PM10 and PM2.5, overall filtration effect
Fruit is good, and material therefor is nontoxic to be worn comfortably.
Existing medical mask is typically all made of non-woven fabrics, but its anti-microbial property is not high, is not able to satisfy the need in market
It asks.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of preparation sides for non-woven fabrics antibacterial agent
Method.Antibacterial agent produced by the present invention has excellent anti-microbial property.
A kind of preparation method for non-woven fabrics antibacterial agent proposed by the present invention, includes the following steps：
S1, zinc nitrate solution, copper nitrate solution are sequentially added into mica, be uniformly mixed and obtain mixed liquor, adjust mixing
The pH value of liquid to neutrality, water-bath is stood, and obtains pretreatment mica；
S2, quaternary ammonium salt solution is added into pretreatment mica, is stirred to react, filters, obtain sediment；
S3, sediment is washed with ethanol water, filtered, it is dry, it grinds, it is dry, obtain antibacterial agent.
Preferably, in S1, mica, zinc nitrate solution, copper nitrate solution weight ratio be 1：25-35：10-20.
Preferably, in S1, the temperature of water-bath is 80-105 DEG C, time 2-4.5h.
Preferably, in S1, the time of standing is 0.5-1.5h.
Preferably, in S1, the mass fraction of zinc nitrate solution is 20-35wt%.
Preferably, in S1, the mass fraction of copper nitrate solution is 10-30wt%.
Preferably, in S2, the concentration of quaternary ammonium salt solution is 5-10g/L.
Preferably, in S3, sediment is washed with ethanol water, is filtered, dry 5-8h, is ground at 120-150 DEG C
Partial size is the powder of 40-60nm, and then the 4-6h dry to powder at 400-600 DEG C, obtains antibacterial agent.
The present invention is in the preparation process in antibacterial agent, by mica and zinc nitrate solution and copper nitrate solution hybrid reaction,
In mica layer area load zinc ion and copper ion, since mica is the silicate mineral with intercalation configuration, interlayer surface band
Positive charge, zinc ion and copper ion can be adsorbed on mica layer surface by electrostatic interaction, pass through control zinc ion and copper ion
Amount, make its endless all standing, and adsorb in mica layer surface bulk type, load then had into the mica of zinc ion and copper ion
Carry out it is quaternary ammonium salt modified, after exchange reaction occurs for mica and quaternary ammonium salt ion, the sheet surfaces of unadsorbed zinc ion and copper ion
It is covered by long alkyl chain, to make the part of the surface of mica be changed into lipophilicity by hydrophily, due to constituting bacteria cell wall
Substance is mostly lipophilic substance, thus modified mica adsorbs bacterium, the bacterium of absorption and load by oleophilic function
Zinc ion and copper ion contact after, zinc ion and copper ion by the synthesis of interference bacteria cell wall, damage bacterial cell membrane,
Inhibit the approach such as the synthesis of bacterio protein to kill bacterium, sterilized by the above method, not only sterilization is fast, and wide spectrum kills
Bacterium makes the present invention have excellent bactericidal property.
