Abstract
A kind of preparation method of nano antibacterial finishing agent, belongs to fabric finishing agent technical field.Comprise the following steps：Take nano silicon dioxide, nano zine oxide and nano-titanium oxide to be dissolved in absolute ethyl alcohol, then add silane coupling agent and be stirred reaction；Take lavender, dandelion and the coptis to carry out heated-air drying respectively, mixed after crushing lavender, dandelion and the coptis respectively after dry, then add deionized water, be heated to reflux, cool down collected after centrifugation supernatant；Dodecafluoroheptyl methacrylate, styrene, neopelex and Nanoscale Iron is taken to add ultrasonic disperse in the mixed liquor after stirring；Then ascorbic acid and supernatant are added, reaction is stirred after heating；Finishing agent natural cooling after stirring evenly, obtains antibacterial finishing agent.The antibacterial finish agent being prepared by the present invention possesses very excellent bacteriostasis property.
Description
Technical field
The invention belongs to fabric finishing agent technical field, and in particular to a kind of preparation method of nano antibacterial finishing agent.
Background technology
Arrange, be last procedure that dyeing and printing process enters market, therefore, its purpose is to eliminate preceding working procedure to be made
Into harmful effect, while assign fabric new function, and the use of finishing agent is then the main means of increase function.In recent years,
As the improvement of people's living standards, the renewal of consumption idea, the whole world of the standardization of market management, especially country textile trade
Change, keen competition makes textile production person's have to improve performance of product cater to market, and wants " quick response ", both
Pattern, style are responded, also to there is special quality, thereby promoting the development of various functions finishing agent.Such as：Ozone
There is cavity in layer, makes ground ultraviolet radiation amount increase, thus stimulates skin canceration, thus also just promotes scientific worker to develop
Succeeded the finishing agent of ultraviolet light.Furthermore new product, the finishing agent to be looked for novelty of new industrial technology.For example, antistatic additive
Use, then proposed because of the rising of synthetic fibers yield, and the clothes of IC Chip Production worker, to antistatic
The requirement higher of effect, so as to also promote the development of antistatic additive.Environmental protection, this is to carry out another strong tide this year
Stream, this is one of main power for promoting finishing agent to update, and some environmentally friendly finishing agents then occurs, such as without aldehyde fixation
Agent, without aldehyde wash and wear finisher etc..All these development for all promoting finishing agent, to adapt to the demand in market, meet consumption
The demand of person.
Antibacterial finishing agent can be mainly divided into inorganic, organic and three kinds natural.Early stage antiseptic belongs to organic system substantially
Row, are all kinds of complex compounds of the element such as nitrogenous, sulphur, chlorine mostly, its principal item has：Quaternary ammonium salt, biguanides, alcohols,
Phenols, aldehydes, organic metal class, arsenic pyridine class, thiophene-based etc..The short-term bactericidal effect of such antiseptic is good, but has mostly heat-resisting
The shortcomings of stability is poor, short life.Especially in recent years, the continuous rise of green consumption idea, promotes in the 21st century,
Adapt to the development of the antibacterial finishing agent of environmental requirement, make more and more products after its processing, application and defunctionalization not
It can damage to human health and ecological environment.Since natural antibacterial agent aboundresources, biodegradable, absorbent properties are good,
And inorganic nano antiseptic dosage is few, efficient, safe and non-toxic, therefore, the inorganic nano antiseptic of development environment close friend and natural
Antiseptic, it will as the research theme of green antibacterial agent.But the antibacterial effect of existing fabric antimicrobial finishing agent and pay no attention to
Think.
The content of the invention
The technical problem of solution：For above-mentioned technical problem, the present invention provides a kind of preparation side of nano antibacterial finishing agent
Method, can be good at killing the microorganism for being harmful to human body and clothing.
Technical solution：A kind of preparation method of nano antibacterial finishing agent, the preparation method comprise the following steps：
Step 1 weighs 3-5 mass parts nano silicon dioxide, 1-2 mass parts nano zine oxide and 0.2-1 mass parts nanometers
Titanium oxide is dissolved in 40-50 mass parts absolute ethyl alcohols, then addition 1.5-2.4 mass parts silane coupling agents, 40-45 DEG C of temperature,
Stirring reaction 2-3h under 300-380r/min rotating speeds；
Step 2 takes 3-6 mass parts lavender, 5-8 mass parts dandelion and the 0.5-1.5 mass parts coptis to carry out heat respectively
Dry 5-10min is air-dried, drying temperature is 81-85 DEG C, and lavender, dandelion and the coptis are crushed to 50-100 respectively after drying
Mesh, adds 40-50 mass parts deionized waters, in 50-60 DEG C of temperature after then mixing the lavender after crushing, dandelion and the coptis
