Description
Technical field
The invention belongs to technical field of biological material, mechanical property and the Ceramic Composite of antibacterial ability are improved more particularly, to a kind of
Thing preparation method.
Background technology
The progress of modern society be unable to do without the development of different kind organism material.Current biomaterial is broadly divided into biologically inert material
Material（Titanium, tantalum, ceramics etc.）, bioactive materials（Bio-vitric, hydroxyapatite etc.）, bioabsorbable material（It is PLA, poly-
Ethanol polymer etc.）Three major types.Bio-inert material is widely used in social every field the most, and ceramics are biologically inerts
The representative of material.
Preferable bio-inert material should possess good mechanical strength, excellent biocompatibility and high corrosion-resisting wear-proof
Property.Ceramic material functionally has its unique superiority, is by shaping and high temperature sintering system with natural or synthetic compound
Into a class inorganic non-metallic material, heat and mechanical properties have the advantages that high temperature resistant, heat-insulated, high rigidity, abrasion performance；
There are insulating properties, piezoelectricity, semiconductive, magnetic in terms of electrical property；There are catalysis, corrosion-resistant, absorption etc. in terms of chemistry
Function；There is certain bio-compatible performance in terms of biology, biological structure material etc. can be used as.
Although current ceramic material achieves rapid progress in these areas, the fatal defects of ceramics are fragility,
I.e. easy fracture, toughness are low.Simultaneously because extensive use of the ceramic material in medical field, bacterium is easily on medical ceramic material
Field planting forms biomembrane and causes persistent infection, and ceramics have no anti-microbial property in itself.Therefore making one kind is needed to improve
Mechanical property, the ceramic complexes with antibacterial ability so contribute to expand the application of ceramic material, especially cured
The application in field.
The content of the invention
Mechanical property and the ceramic complexes preparation method of antibacterial ability are improved it is an object of the invention to provide a kind of, is led to
The mechanics that simple ceramic material does not have originally can not only be significantly improved by crossing the ceramic complexes that this preparation method produces
Performance（Including anti-impact force, tensile resistence, warping resistance power etc.）, and can have with the unexistent antibiotic property of pre-ceramic
Can, various infection risks can be reduced.
The object of the present invention is achieved like this：
It is a kind of to improve mechanical property and the ceramic complexes preparation method of antibacterial ability, be characterized in：
A, with CATIA Software for Design, ceramic die is built by 3D printing technique as needed；
B, according to gel-casting method ceramics are built, component ratio is as follows：1.5-2.5 grams of acrylamide, N, N are weighed respectively

20-50 grams of ceramic powder of rice, 0.16-0.24 grams of ammonium persulfate, by acrylamide, N, N methylene bisacrylamides acyl, citric acid three
Ammonium, deionized water, 2% weak aqua ammonia, nano-ceramic powder and ammonium persulfate are thoroughly mixed 5 microlitres of N of addition after 0.5-1 hours,
N, N, N- tetramethylethylenediamine, stir 10-15 seconds, obtain ceramic liquid；Ceramic liquid is slowly equably poured into ceramic die, will
Ceramic die be placed in vacuum drying chamber 50-60 degrees Celsius it is dry 36-48 hours, obtain dry ceramic idiosome；Will be dry
Ceramic idiosome is taken out, and progressively heating firing ceramics, to 1000-1300 degrees Celsius, are burnt and are incubated 2- to the highest temperature under nitrogen protection
3 hours, room temperature is then progressively cooled to, the ceramics of pure white finishing are obtained；
C, before use, first by the first layer material：Component A ISO（Carbimide）With B component Resin（Resin）Two components are according to 1：
3—3：1 volume range mixing is preset in the environment that temperature is 11-42 DEG C；Two kinds of components are further heated to 39-75
Degree Celsius, it is according to 500-4000psi hydraulic sprayings to ceramic surface, ceramic surface is complete using the compound spraying equipment of high pressure
Full parcel, obtains wrapping up the first layer material：I＆R layers of intermediate ceramics；
D, according to following ingredients ratio prepare the second layer material：Nano zine oxide：800 ml deionized waters, 80mM are weighed respectively
NH3•H25.714 milliliters of O, 50mM Zn (NO3)2•6H214.875 grams of O, 3.5046 grams of 6- methenamines, by deionized water,
NH3•H2O 、Zn(NO3)2•6H2After the mixing of O, 6- methenamine, closing is stirred, 65 C water baths 15 minutes,
Go hd to open wide for 10-15 minutes, continue to close 85 C water bath 24-48 hours, obtain nano zine oxide；

Material：Nano oxidized zinc layers, finally give the finished product by I＆R layers and nano oxidized zinc layers bilayer modification parcel：Ceramic complexes.
Nano-ceramic powder in step 2 is one kind in nano zircite, nano aluminium oxide or nanometer hydroxyapatite.
In order to verify the performance of the ceramic complexes prepared, tested as follows respectively：
1st, Experiments of Machanics：
Ceramic material is divided into experimental group and control group.The ceramic complexes that experimental group is wrapped up for double-deck modification, and control group is
Pure ceramic material without parcel（Step B：Ceramics）.By two groups of ceramic materials carried out respectively on magnificent imperial testing machine impact experiment,
Bending experiment, stretching experiment and compression experiment.Three samples of each every group of mechanical test, are repeated 3 times above-mentioned experiment, row statistics
Analysis.
2nd, antibacterial experiment：
Ceramic material is divided into experimental group and control group, is divided into the detection of two parts antibacterial experiment.Part I is pure ceramic material
（Step B：Ceramics）With the anti-microbial property contrast of I＆R layers of intermediate ceramics.Experimental group is I＆R layers of intermediate ceramics, control
Group is pure ceramic material.Part II is the ceramic complexes that experimental group is I＆R layers and nano oxidized zinc layers double wrapped, and right
It is ceramic for I＆R layers of intermediate according to group.Different materials are predominantly detected to staphylococcus aureus（Staphylococcus aureus）And Escherichia coli（Escherichia coli）Anti-microbial property.5 milliliters of Luria Bertani liquid is taken, 100 is micro-
Rise bacterium solution and sample is sufficiently mixed and co-cultured 24 hours in orbital shaker vibrations.100 microlitres of bacterium solutions are taken after 24 hours and are diluted
105Times.Then 50 microlitres of bacterium solutions are taken uniformly to be applied to culture dish（Bacterium coated plate method）, after 37 degrees Celsius of insulating box cultures 24 hours
Take out number bacterium colony, the anti-microbial property of different groups of observation.It is repeated 3 times above-mentioned experiment, row statistical analysis.
Above-mentioned experimental result is shown：Experimental group mechanical property in impact experiment, bending experiment, stretching experiment compared with control group
Conspicuousness is improved, with significant difference.And in compression experiment two groups of no significant differences；In pure ceramic material and I＆R layer
Mesosome ceramics are without antibiotic property, and the ceramic complexes of I＆R layer and nano oxidized zinc layers double wrapped have good antibiotic property, have
Significant difference.
