Abstract
The invention relates to a nano antibacterial agent and process for preparation, wherein the raw materials include (by weight percent) nano titanium oxide 1-25%, nano silver 1-10%, nano zinc oxide 1-50% and balancing water. The preparing process consists of charging nano titanium dioxide into autoclave, elevating temperature and stirring to 150 deg C, charging zinc oxide and nano silver for reacting 3 hrs, finally cooling down to 30 deg. C.
Description
Technical field
The present invention relates to a kind of preparation technology of antibacterial agent, especially a kind of preparation technology of nano antibacterial agent.
Background technology
Usually antibacterial agent is divided into organic antibacterial agent and inorganic antiseptic, organic antibacterial agent generally exist poor heat resistance, volatile, be difficult for preserving for a long time, easily decompose and produce shortcomings such as nuisance, safety be relatively poor, and inorganic antiseptic is generally powder, is difficult to disperse in water, and dissolubility is bad.In addition, the antibacterial agent on the market only plays antibacterial action to some bacterial classification, does not reach antibiotic popularity.
Summary of the invention
In order to overcome the deficiency of above-mentioned organic antibacterial agent and inorganic antiseptic, the invention provides a kind of preparation technology of inorganic antiseptic.
The same nano titanium oxide of the present invention, Nano Silver, nano zine oxide and water fully react and form.
Nano titanium oxide has excellent anti-microbial property, is based on light-catalyzed reaction and makes the organic matter decomposition and have antibacterial effect.Nano titanium oxide under the irradiation outside the sunlight ultraviolet, can decomposite by the electronegative electronics (e that moves in the system of water and air voluntarily
-) and the hole (h of positively charged
+), series of chemical takes place, form hole-duplet.The oxygen trapped electron that absorption is dissolved in titanium dioxide surface forms O
2 -, the hole then will be adsorbed on the OH of titanium dioxide surface
-And H
2O is oxidized into HO.The elemental oxygen of generation and hydroxyl free radical have very strong chemism, particularly elemental oxygen can react (oxidation) with most organic matters, can react with the organic matter in the bacterium simultaneously, generates carbonic acid gas and water, thereby at short notice with regard to energy killing bacteria and greasy dirt.
Silver is a kind of disinfectant widely, have purify water, the effect of preservation and antisepsis.Nano Silver has stronger bactericidal action than silver, and its antibacterial action mechanism is: nano-Ag particles directly enters thalline and (SH) combines, thalline is choked to death with the oxygen metabolism enzyme; Energy and bacteria cell wall play the glycan reaction, produce moldable compound, stop the germ activity, kill pathogens; Silver can with the DNA combination of pathogene, cause structure variation, suppress dna replication dna, cause germ to lose vigor.The mechanism of action of this uniqueness can kill microorganisms such as most of bacteriums of being in contact with it, mould, spore.Find after deliberation: Nano Silver is selected pathogenic bacteria of drug-resistant, as: resistance Escherichia coli, resistance golden staphylococci, drug-resistant pseudomonas aeruginosa, streptococcus pyogenes, resistance enterococcus, anaerobic bacteria etc. all have stronger antibacterial activity; To burn and scald and the common bacterium of wound surface, as: staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and other G
+, G
-Pathogenic bacteria etc. all have bactericidal action; Gonococcus to chlamydia trachomatis, sexually transmitted disease also has powerful bactericidal action.Nano Silver compare with common silver products have potent sterilization, quick sterilization, antibiotic lasting, permeability strong, promote healing, safe, the characteristics that have no drug resistance.
Realize that concrete technical scheme of the present invention is: a kind of preparation technology of nano antibacterial agent, the preparation raw material is made up of nano titanium oxide, Nano Silver, nano zine oxide and water, its mass percentage content is: nano titanium oxide 1～25%, Nano Silver 1～10%, nano zine oxide form 1～50%, and surplus is a water;
Nano titanium dioxide is put into reactor heat up, add nano zine oxide and Nano Silver reaction 3 hours after being stirred to 150 ℃, be cooled to 30 ℃ of nano antibacterial agents that get product.
For the nano antibacterial agent that makes preparation has more excellent anti-microbial property, further: described preparation raw material preferred mass degree is: nano titanium oxide 10～25%, Nano Silver 3～8%, nano zine oxide 20～40%, surplus are water.
Described nano titanium oxide particle diameter is 10～30 nanometers, and described Nano Silver particle diameter is 20～60 nanometers, and described nano zine oxide particle diameter is 20～40 nanometers.
Nano titanium oxide is the primary raw material of nano antibacterial agent, and it is the anatase titanium dioxide crystal, and major function has a series of antibacterial effects such as antibacterial and mouldproof, is a kind of well-known asepsis environment-protecting material, can be widely used in water treatment, can deodorizing, degradation of organic substances; Nano Silver is a kind of application anti-biotic material very widely, and addition is few, but antibacterial effect is fabulous; Nano zine oxide can combine nano titanium oxide and nanometer money kind product very widely, so that product reaches extremely strong antibiotic, fungistatic effect.
Preparation technology of the present invention is simple, the finished product nano antibacterial agent be inorganic aqueous, for colourless transparent liquid, soluble in water, can efficient sterilizing, antibiotic, deodorizing.
Embodiment
A kind of preparation technology of nano antibacterial agent, the preparation raw material is made up of nano titanium oxide, Nano Silver, nano zine oxide and water, and its mass percentage content is: nano titanium oxide 1～25%, preferred 10～25%; Nano Silver 1～10%, preferred 3～8%; Nano zine oxide forms 1～50%, preferred 20～40%; Surplus is a water.Described nano titanium oxide particle diameter is 10～30 nanometers, and described Nano Silver particle diameter is 20～60 nanometers, and described nano zine oxide particle diameter is 20～40 nanometers.
Nano titanium dioxide is put into reactor heat up, add nano zine oxide and Nano Silver reaction 3 hours after being stirred to 150 ℃, be cooled to 30 ℃ of nano antibacterial agents that get product.。
Agricultural University Of South China veterinary college poultry diease research department can deactivation H5N I avian influenza virus to the nano antibacterial agent of 1: 5000 times of dilution of avian flu virus detection and the effect of H5 subtype avian influenza virus more than 5 minutes.
Institute for Environment Hygiene and Health Related Product Safety, China CDC is detected, and poisoning symptom does not all appear in each the dosage treated animal test of contamination back, and this is tried thing and is the 10000mg/kg body weight to small white mouse is female, male through LD50, belongs to actual nontoxic level.
Detect through microorganism detection center, Guangdong, can extremely strong killing action all be arranged all kinds of bacterium such as Escherichia coli, staphylococcus aureus, Friedlander, the mutation of bacillus subtilis black and candida albicans.
