The preparation of B, glaze slip
The raw material of the compound antibacterial powder in step A and other proportionings is added in ball mill, wet ball grinding is carried out to glaze
It is 2～4% that slurry fineness is 325 mesh 10000-hole sieve screen over-sizes, obtains glaze slip；
The preparation of C, antiseptic sanitary glaze
Glaze slip in step B is imposed on sanitary ceramic body surface, using tunnel cave, is aoxidized at 1200～1250 DEG C
Fire in atmosphere, its heating rate is 2.5～3 DEG C/min, firing period is 16～18h, is incubated 2～3h, i.e., in sanitary ceramics
Antiseptic sanitary glaze is obtained in billet surface.
The invention has the beneficial effects as follows：
1) present invention is using chemical synthesis synthesis silver molybdate, zinc molybdate antimicrobial powder, and preparation method is simple to operation, former
Material low cost.
2) silver molybdate, zinc molybdate and titanium dioxide powder are constituted into proportion compound antibacterial powder, by it as additive
In being introduced into ceramic glaze, with reliable antibiotic property, glaze nondiscolouring during high temperature.
Its Antibacterial Mechanism of antiseptic sanitary glaze of the present invention：One is the presence due to moisture, the silver molybdate of glaze, zinc molybdate
The silver-colored zinc ion being sustained out is entered in bacterium body, destroys the respiratory system and electric transmission system of microbial cell, causes enzyme
Damage；Two is that silver ion and optically catalytic TiO 2 form the very strong hydroxyl of activity certainly with the water and oxygen for being adsorbed in its surface
By base and active oxygen, can react with most organic matters (including the organic matter in bacterium), carbon dioxide and water be generated, so as to short
Bacterium is killed in time, stench and greasy dirt is eliminated, so as to ensure glaze antibiotic property.

Antiseptic sanitary glaze.
1st, antiseptic sanitary glaze anti-microbial property test
Using colony counting method, by determining comparative example with embodiment antimicrobial sample and bacterial number increase and decrease in control sample
Method evaluating the anti-anti-microbial property of material.
Specific experiment step：
A. will by coupons l.0cm × 3.0cm and control print (with by coupons homogeneous material, equal size, but do not contain
Anti-biotic material, and sterilized process) each 3, it is divided into 3 groups and is placed in the PBS solution of sterilizing.Add tested bacterial liquid culture
It is placed in 36 DEG C of insulating boxs after dilution, fully vibration and cultivates 6h.
B. bacterium solution 0.5ml after culture is taken with pipette, is instilled containing (attention in 4.5ml sterilizing PBSs along tube wall
Pipette tip should not touch in-line dilution liquid), tube shaken is well mixed, and is made 1:10 dilution.
C. 1ml sterilizing pipettes are separately taken, by aforesaid operations order, make 10 times of incremental thin liquids, be so often incremented by dilution once,
Use 1 1ml sterilizing pipette instead.
D. will cool down in the culture dish of the nutrient agar injection sterilizing of proper temperature standby.
E. 3 acceptable diluent degree are selected, respectively while making 10 times and being incremented by dilution, i.e., drawing the dilution liquid relief
Pipe moves 0.1ml in culture dish, and is coated with uniform.Each dilution factor makees two culture dishes.
F. culture dish is put into 36 DEG C of constant incubator, takes out after 18～24h of culture and count.
G. method for counting colonies.Flat board of the clump count between 30～300 is chosen as total plate count bioassay standard.One
Dilution factor uses two flat boards, should adopt two flat board averages, when its middle plateform has larger sheet colony growth, does not then adopt
With, and using the flat board without sheet colony growth as the dilution clump count, if sheet falls less than the half of flat board, and remaining
Bacterium colony distribution is again very uniform in half, you can calculates and take advantage of 2 to represent full ware clump count after half flat board.
H. calculate in bacteriostasis rate (part)=(A-B)/A × 100 formula：A represents non-anti-bacteria ceramic control sample and averagely reclaims bacterium
Number；B represents the average bacterial count recovered of test specimen (comparative example and embodiment).
Antiseptic sanitary glaze (comparative example and embodiment) and non-anti-bacteria ceramic control sample are put into by the above process
In being diluted to certain density colibacillary cushioning liquid, after immersion 24h their antibiotic rate is tested.As a result such as table 1.
The anti-microbial property of the antibacterial ceramic glaze of table 1
| Embodiment | Clump count before sterilized | Clump count after sterilization | Antibiotic rate (%) |
| Embodiment 1 | 2650 | 133 | 95.0 |
| Embodiment 2 | 2650 | 90 | 96.6 |
| Embodiment 3 | 2650 | 95 | 96.4 |

| Comparative example 2 | 2650 | 1315 | 50.4 |
| Control sample example | 2650 | 2650 | 0 |
It can be seen from Table 1 that, antiseptic sanitary glaze of the present invention, antibiotic rate is up to 95～96%.When antimicrobial powder exists
When the solubility of glaze reaches saturation, increase its content, the ion that glaze superficial dissolution goes out will not change, such as comparative example 1, resist
Bacterium powder content has increased to 8 parts, compared with 2.5 parts of antimicrobial powder content in embodiment 2, the two other preparation condition all same,
But antibacterial effect essentially unchangedization.
2nd, antiseptic sanitary physicochemical property test
Comparative example and embodiment antimicrobial sample and non-anti-bacteria ceramic control sample are done by physical and chemical quality according to GB6952-2015
Testing result such as table 2.It can be seen from the test results that, no matter outward appearance is detected or physical and chemical performance detection anti-bacteria ceramic, is met
Standard.
The antiseptic sanitary glaze physical and chemical quality testing result of table 2
| Embodiment | Aberration | Water absorption rate (%) | Crack resistance | Open defect | Antibiotic rate (%) |
| Embodiment 1 | It is unobvious | 0.3 | Flawless | Nothing | 95.0 |
| Embodiment 2 | It is unobvious | 0.3 | Flawless | Nothing | 96.6 |
