Abstract
The invention discloses a simple method for preparing a nano-silver antibacterial solution, which is mainly characterized in that the nano-silver solution is prepared by taking a high-pressure sterilizing pot as a reaction environment, utilizing silver nitrate as a silver source and using soluble starch and other polysaccharide substances as protective agents; the average particle size of the nano-silver in the solution is less than 10 nanometers; the solution can have antibacterial effects under low concentration; and the method is simple in process, high in efficiency, high in the concentration (up to 10000 ppm) of the prepared nano-silver solution, few in impurities and high in stability, and can be widely applied to electronic, textile, medical health, food, coating, plastic and other fields.
Description
Affiliated technical field
The present invention relates to a kind of nano-silver antiseptic solution preparation method, belong to nano material and technical field.
Background technology
Microorganism is because individual little, breeding rapidly, to human and environmental hazard is quite serious: spread disease, break out the interior epidemic disease of world wide more than once, talk SARS now and bird flu is also had a lingering fear; Can cause food pollution, water pollutes, and pollutes bibliographic file, the art work, influences the biopharmaceutical products quality, and therefore the infringement precision electronic device prevents that microorganism harm (antibiotic) is urgently important.
Nano Silver has antibacterial and deodouring, and water purification is anticorrosion, and the effect of medical treatment also has antibiotic wide spectrum simultaneously, and sterilization is potent, and permeability is strong, and is antibiotic lasting, safety non-toxic, the characteristics that have no drug resistance.Can be widely used in the fields such as electronics, weaving, health care, food, coating, plastics.Synthetic for Nano Silver, common chemical synthesis process generally will be used surfactant, reductant, and as ascorbic acid, glucose, hydrazine hydrate, boron hydride, trisodium citrate, sodium hypophosphite etc.Chinese patent liquid nano silver simple substance preparation method (200510036375.4) complex process, raw material is more, and the reaction time is long.A kind of preparation method of Nano silver solution (200710049605), raw material has been used reductant, gellan gum, adjuvant, surfactant, particle diameter are relatively large 3-60nm.With the high polymer is the preparation method (200510049258) of the Nano silver solution and the nano silver powder of stabilizing agent, and raw material is also comparatively complicated.Outside raw material desilver source of the present invention and the water, only need a kind of macromolecule dispersant to get final product, protectant plays the effect of reduction silver ion simultaneously.The short production that in 30 minutes, can finish Nano Silver of process time.Therefore raw material is simple, and cost is extremely low, is convenient to large-scale production.Do not use any organic solvent simultaneously, all reagent in the nano-silver water solution preparation of the present invention all are through U.S. FDA or ministry of Health of China approval, meet requirements of green environmental protection.
Goal of the invention
The objective of the invention is in order to obtain a kind of ultra-fine grain diameter, particle diameter is distributed in 1-10nm, and good dispersion has the nano-silver water solution of excellent anti-bacterium capability.In order to reach this purpose, select safety non-toxic for use, the soluble starch of wide material sources, polysaccharide such as hydroxyethylcellulose are reductant and stabilizing agent.
Summary of the invention
Principle of the present invention:
(1) owing to soluble starch, polysaccharide such as hydroxyethylcellulose belong to polymer substance, can be to the synthetic protective colloid action that plays of Nano Silver.
(2) polysaccharide such as soluble starch contains reproducibility group-OH, can be with Ag
+Be reduced to Ag.
(3) silver salt that is adopted has silver nitrate or silver sulfate.
(4) used solvent distilled water, deionized water, running water.
The present invention has following advantage compared to existing technology:
1, the present invention adopts polysaccharide such as soluble starch as protection reagent, and is reflected at and finishes in 30 minutes, so the present invention has that material source is wide, the open-and-shut advantage of technology.
2, the present invention is in whole process of preparation, has nontoxicly owing to adopt, and the good polysaccharide such as soluble starch of wetability so solution is single dispersion, have storage stability preferably as dispersant and reductant, and whole process of preparation is also pollution-free.
3, the prepared Nano silver solution particle diameter of the present invention has good storage stability less than 10nm.
