Description
Technical field:
The present invention relates to a kind of nanometer compound fungicide and preparation method thereof, particularly Nano Silver/hydroxyapatite nano band assembling ball compound disinfectant and preparation method thereof.
Background technology:
The metallic element that uses in the existing inorganic fungicide mainly is the silver, copper, zinc to human body safety etc., and wherein Yin sterilizing ability is the strongest, so it is most important one main kind of in the inorganic sterilization material, is subjected to people's attention day by day.Silver is that the sterilization mechanism of bactericide is commonly considered as because following several respects effect can take place touching microorganism after for silver compound or silver metal particle: suppress microorganism breathing, hinder synthetic, the combination that destroys protein, damaging cells film, interference DNA of enzyme.Nano silver particles has than common silver compound or the excellent more bactericidal activity of silver metal particle, is used for all kinds of washings, health product in a large number.

2) be called for short HA or HAP, be present in widely in human body and animal skeleton and the tooth, the chemical bond very strong with bone formation is desirable hard tissue substituting material.In the biomimetic material field, HAP transplants in filling material of bone, artificial dental root, artificial jawbone, artificial nose's cartilage, the skin etc. except being used to make, can also and the compound preparation HAP of other material Biocomposite material; At field of medicaments, HAP can be used for drug loading, forms drug sustained release system; At sterilization, catalytic field, utilize its excellent biological compatibility, can prepare antibacterial ability is strong, safety is good composite antibacterial material and catalyzer etc.In the bioactivator Separation ﹠ Purification, other fields such as daily use chemicals also have suitable application prospects.When being reduced to nanoscale as if particle size with hydroxyapatite, resulting nano hydroxyapatite material has the physicochemical property more excellent more than common hydroxyapatite material: higher as solvability, surface area is bigger, biologically active is better, and has cancer suppressing action and good bio-compatibility and stability etc.
In the preparation of inorganic compounding bactericide, be the compound disinfectant of carrier with the hydroxyapatite since have high temperature resistant, sterilizing power is strong, many characteristics such as adsorbable organic matter have also caused scientific research personnel's very big interest now.Have some reports at present both at home and abroad, disclose the method for preparing bactericide with common hydroxyapatite load silver, zinc ion as Chinese patent CN1711847 hydroxyapatite material and the compound preparation sterilization material of other materials; Li Jidongs etc. have been studied the preparation method of copper-loaded nanometer hydroxyapatite bactericide, and to its bactericidal property carried out estimating (functional material, 2006, (04), 635-638); Chinese patent CN1739357 discloses a kind of nanometer composite silver carrying hydroxyapatite stone/titanium dioxide disinfection preparation methods, promptly the mineral salt with titanium, silver, calcium, ammonium are raw material, adopt liquid-phase coprecipitation, the preparation argentum-carried hydroxylapatite, then argentum-carried hydroxylapatite is scattered in the colloidal sol that the mineral salt hydrolysis of titanium obtains, in conjunction with subsequent heat treatment, obtain argentum-carried hydroxylapatite/nano titanium oxide composite granule.
But, employed hydroxyapatite carrier material all is the hydroxyapatite of conventional granulates size in these relevant reports of compound disinfectant at present, perhaps common nanotopography, nano hydroxyapatite material as nano bar-shape and nano particle shape, therefore prepared Nano Silver/nanometer hydroxyapatite compound disinfectant specific surface area is less, flowability and less stable.
Summary of the invention
The purpose of this invention is to provide that a kind of specific surface area is big, the nanometer compound fungicide of flowability and good stability and preparation method thereof.
The present invention is achieved through the following technical solutions:
A kind of nanometer compound fungicide comprises hydroxyapatite nano band assembling ball, Nano Silver, surfactant and water, and its content (percentage by weight) is: hydroxyapatite nano band assembling ball 4.7-5.9wt%; Nano Silver 0.3-1.6wt%; Surfactant 0.3-1.6wt%; Water 92-93wt%.
The preparation method of nanometer compound fungicide is:
1, take by weighing the hydroxyapatite nano band assembling ball that percentage by weight is 4.7-5.9%, it is joined in the beaker, adding percentage by weight is the water of 92-93%, stirs 3 hours;
2, adding percentage by weight is the surfactant of 0.3-1.6%, sonic oscillation 30 minutes or stirred 1 hour;
3, take by weighing the Nano Silver that percentage by weight is 0.3-1.6%, sneak in the above-mentioned system, sonic oscillation 30 minutes or stirred 2 hours promptly obtains Nano Silver/hydroxyapatite nano band assembling ball compound disinfectant.
Wherein, described Nano Silver is spherical, and sheet is bar-shaped, wire, unformed shape particle or its mixture.Described surfactant is non-ionic surface active agent or anion surfactant.Non-ionic surface active agent preferred fat alcohols, polyethylene glycols, polyvinyl alcohol, alkylolamides class, alkyl amine, alkylbenzene phenols or its mixture; Anion surfactant optimization acid salt, phosphate, sulphate, sulfonate or its mixture.
It is the bactericide carrier that the present invention adopts hydroxyapatite nano band assembling ball, and the bactericidal nano-silver active constituent loading on hydroxyapatite nano band assembling ball, is made Nano Silver/hydroxyapatite nano band assembling ball compound disinfectant.Because hydroxyapatite nano band assembling ball is with respect to common nano hydroxyapatite material, have some better nano-meter characteristics, make prepared Nano Silver/hydroxyapatite nano band assembling ball compound disinfectant have bigger specific surface area, better mobile and stable.
