Description
Technical field
The invention belongs to the antibacterial agent technical field, specifically, relate to a kind of nano silver antimicrobials, the invention still further relates to the preparation method of this nano silver antimicrobials.
Background technology
Silver just is used to treat the knife wound sword cut in ancient times, and Compendium of Material Medica is on the books to the sterilizing function of silver; " Essential Chemistry element " also the sterilizing function to silver is described: silver has peculiar effect as bactericide, and 1% liquor argenti nitratis ophthalmicus is the medicine commonly used of treatment eye conjunctivitis.Argent has strong bactericidal action.
Nano Silver (Nano Silver) is meant and utilizes the forward position nanometer technology with silver-colored nanorize, particle diameter is accomplished nano level argent simple substance.The Nano Silver particle diameter is less than 100nm, and generally between 25-50nm, nanometer technology occurs; Make the sterilizing ability of silver under the nanometer state produce qualitative leap; Few Nano Silver can produce powerful bactericidal action, can in several minutes, kill 650 various bacteria, and the broad-spectrum sterilization drug resistance is little; Can promote the healing of wound, the growth of cell and the reparation of damaged cell; Toxic reaction is little, and skin is not found any IR yet, and this comes the antibiotic wide prospect of having opened up for the extensive use Nano Silver; Be the natural antibacterial agent of a new generation, bactericidal nano-silver has the advantages that broad-spectrum antiseptic, permeability are imitated sterilization, antibiotic lasting, washability, repeatability, safety non-toxic by force, by force and had no drug resistance.The nanometer silver antimicrobial micro mist all has exhibited strong inhibition and killing action to tens of kinds of pathogenic microorganismss such as Escherichia coli, gonococcus, chlamydia trachomatises, and can not produce drug resistance.Animal experiment shows that this nanometer silver antimicrobial micro mist is several thousand times that usage amount reaches standard dose, and animal subject does not have poisoning manifestations yet.Simultaneously, it also has the promotion repair to impaired epithelial cell.What deserves to be mentioned is that this product is met the water antibacterial effect and more strengthened, and is more conducive to treatment of diseases.Medically, 0.5% silver nitrate is the standard liquid of treatment burn and wound; The liquor argenti nitratis ophthalmicus of 10-20% is smeared, and can be used to treat cervical erosion.In addition, this nanometer silver antimicrobial micro mist also can be widely used in fields such as environmental protection, weaving dress ornament, fruit freshness preserving, food hygiene.
Chinese invention patent 01110767 " anti-wide-spectrum antiseptic nanometer silver micro mist and the inductrial production process assembled " discloses a kind of anti-gathering wide-spectrum antiseptic nanometer silver micro mist and inductrial production process, with firm being adsorbed on some natural many spaces vegetable materials of nano silver powder.Chinese invention patent 02138891 adsorbs nano silver powder with cavity or the ghost of algae.These two patents all are to be preparing carriers nano-Ag particles body with the porous material, all do not solve the coating problem in the antibacterial agent use.
Chinese patent CN1277476C discloses a kind of water soluble polymer that uses and has been stabilizing agent; Obtain the method for Nano Silver with water-soluble reductant reduction silver nitrate; This method prepares process need generation chemical change; The difficult control of the reduction of silver ion, the used in amounts of silver nitrate and water-soluble reductant will accurately be controlled, and is unfavorable for large-scale industrial production.
The preparation method that Chinese patent CN101171929A disclosed a kind of nano silver antimicrobials on 07th in 05 month in 2008 gets distilled water or deionized water, adds nanometer silicon dioxide, and polyvinylpyrrolidone is mixed and mixed; Add silver nitrate again, the sodium borohydride reduction agent, through stirring, disperseing, fully reaction makes nano silver antimicrobials colourless transparent solution, bottled packing.This invention has just adopted materials such as silver nitrate, polyvinylpyrrolidone, sodium borohydride to mix dispersed with stirring, contains a large amount of harmful substances such as nitrate ion in the Nano silver solution that this method is produced out.
Summary of the invention
The technical problem that the present invention will solve is to above deficiency, proposes a kind of to object strong adhesion, good film-forming property, burnish resistance is good and antibacterial action is grown nano silver antimicrobials.
Another technical problem that the present invention will solve provides a kind of preparation method of nano silver antimicrobials, and this method is workable, can prepare nano silver antimicrobials with simple method.
