Description
Affiliated technical field:
The present invention relates to a kind of antibacterial agent material, relate in particular to a kind of inorganic complex antimicrobials material.It can be applicable to fields such as packaging for foodstuff, construction material, medical equipment, amenities, articles for daily use, cleaners and polishes, household electrical appliance, Communication Equipment.
Background technology:
Noxious bacteria is present in the various occasions around us, as housing floor, the metope of living, the furniture of use, household electrical appliances, clothing and articles for daily use etc.1996, the national infection incident of 0-157 Escherichia coli of Japanese large tracts of land outburst was not only seized many people's life, and caused that the whole world is panic.According to statistics, the whole world is annual because of bacterial infection causes dead number near 2,000 ten thousand, accounts for more than 30% of dead sum; The intersection bacterial infection rate of each hospital surpasses 10%.Will prevent effectively that bacterium from producing and grow, using anti-biotic material is the most simple and efficient method.Anti-biotic material is meant the class new function material with sterilization and bacteria growing inhibiting function.
Antibacterial agent mainly contains inorganic, organic and natural three major types.Natural antibacterial agent comes from the natural extract material, as shitosan, Hinokitiol etc., natural antibacterial agent toxicity is little, safe, but service life is short, poor heat resistance (150~180 ℃ of charings are decomposed), is mainly used in disposable plastic products such as food pack.The organic antibacterial agent main component is tetravalence amine salt, alcohols, biguanides material, have instant effect, characteristics that sterilizing ability is strong, but easily produce the microorganism drug resistance, and there are deficiencies such as easily migration, poor heat resistance, many organic antibacterial agents are easy decomposition failure under high temperature, high pressure, high shear processing conditions, and catabolite causes secondary pollution.Inorganic antiseptic adopts the physical adsorption ion-exchange process, and metals such as silver, copper, zinc are carried on porous material surface, utilizes the antibacterial action of metal ion, reaches the purpose of long-acting bacteriostatic by slow releasing function.Inorganic antiseptic does not produce drug resistance and safety is good, and particularly its outstanding warm tolerance (>600 ℃) has very big advantage in the application of multiple antibacterial product.Existing inorganic antiseptic is mainly based on silver and zinc ion, wherein best with the antibacterial effect of silver ion, but silver ion antimicrobial agent exists and easily to be reduced and variable color (being grey black) and cost high two big shortcomings, and simple substance is silver-colored to be lost or weaken its antibacterial effect greatly owing to becoming after reducing.At present, have and report that much nano material has antibiotic property, but simple nano material has very big surface area because particle diameter is too little, be difficult in use fully disperse, even can't disperse.Coat processing so all will carry out the surface before using to it.The result who coats greatly reduces the performance of nano effect and antibacterial action on the one hand, and this on the other hand processing procedure also is very loaded down with trivial details.Moreover, more existing nano-powder materials are (as nano-TiO
2) will rely on photocatalysis just to show certain antibacterial effect.(spy opens flat 5-912 to Japan Patent, Te Kaiping 8-133918) report is compound with four acicular type zinc oxide crystal whisker and silver salt, prepared inorganic antiseptic and in different materials and environment, obtained to use (Te Kaiping-93365 with excellent antibacterial effect, Te Kaiping 5-78498, Te Kaiping 78218, Te Kaiping 6-140731 etc.), the technology of these Japan Patent reports is utilized the spicule activated centre and the point effect of ZnOw, activate airborne water and oxygen, produce hydroxyl radical free radical (OH) and active oxygen ion (O
- 2), destroy bacteria live and multiplication capacity and make bacterium death, and reach antibacterial effect.But owing to use common ZnOw, its whisker length reaches 30-100 μ m, and root diameter (RD) slightly reaches 0.1~10 μ m.Its spicule activated centre is few, and point effect is poor, in order to improve antibacterial effect, add silver ion as one of main antibacterial activity composition, and wherein silver ion still faces discoloration problem.
Summary of the invention:
It is strong to the purpose of this invention is to provide a kind of sterilization antimicrbial power, and it is stable that antibiotic process of sterilization and effect can repeat to continue to carry out, act on, and nondiscolouring, also need not light-catalysed ZnOw complex antimicrobials composition.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ZnOw complex antimicrobials composition, component that contains and weight proportion are: 50~80 parts of four acicular type zinc oxide crystal whiskers, 5~25 parts of nano zine oxides, 5~25 parts of nano-titanium oxides, 10~40 parts in sodium silicate carrier.
The invention has the beneficial effects as follows: 1, the spicule activated centre and the point effect of ZnOw can produce and discharge active oxygen repeatedly, and have extremely strong and stable oxidation disinfection antibacterial ability; On this basis, the present invention has added nano-ZnO, nano-TiO
2,, antibacterial effect is further strengthened because distinctive skin effect of nanoparticle and small-size effect are given their high catalytic activitys.2, a spot of nanoparticle is a mesoporous material with the sodium silicate inorganic carrier, fixes and adsorbs nano-ZnO and nano-TiO by physical adsorption
2Particulate; Avoided simple nano antibacterial agent, a large amount of nanoparticle difficulties in dispersion easily produce the problem of secondary agglomeration, have both guaranteed the dispersed and stable of nanoparticle, can reach long acting antibiotic by slow releasing function; Simultaneously, the spicule activated centre of ZnOw and point effect effect make nanoparticle need not to rely on photocatalysis just can produce antibacterial action again.3, no silver ion easy to change and expensive in the composition, not easy to change in storage and the use, and reduced manufacturing cost.
The length of above-mentioned four acicular type zinc oxide crystal whisker is 1~10 μ m, and root diameter (RD) is 0.1~2 μ m.
Because the length of the pin of the ZnOw (ZnOw) that adopts is 1~10 μ m, length 30~200 μ m much shorters of general ZnOw, can make the antibacterial agent of Unit Weight contain more four spicule activated centres and most advanced and sophisticated nano effect, can make product reach higher fineness simultaneously; ZnOw spicule root diameter (RD) is controlled in 0.1~2 mu m range, and its tip and border show the distinctive high surface effect of nano material; Can activate airborne water and oxygen faster, more repeatedly, produce hydroxyl radical free radical (OH
-) and active oxygen ion (O
- 2), can destroy bacteria live and multiplication capacity in the short time and make bacterium death.So its sterilization antimicrbial power further strengthens, the sterilization antibacterial action is more stable.
Also can contain 1~5 part Li in the lattice of 50~80 parts of four acicular type zinc oxide crystal whiskers of the present invention
+, Na
+, K
+The mixture of one or more in three kind of one valent metal oxide.
Make the ZnOw in the antibacterial agent contain the oxygen content that exceeds the quata like this, improved release active oxygen (O
- 2) ability, further improved antibacterial effect.
Test shows: complex antimicrobials composition of the present invention, the antibiotic longer duration of its sterilization, antibacterial agent can play a role repeatedly, minimum inhibitory concentration (MIC) only is 50~150PPM, the material (plastics, coating etc.) that adds 2% this antibacterial agent to the antibacterial effect of common bacterias such as staphylococcus aureus, Escherichia coli, salmonella and candida albicans all above 90%; And this antibacterial agent all do not have any stimulation to test with eyes and the skin of mouse and rat, and its half lethal dose surpasses 10000mg/Kg, the nontoxic grade of product in true border.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
