Part, 5~6 parts of carborundum powder, 0.1~0.2 part of silver-series antibacterial agent, 3~8 parts of pigment.
Preferably, by weight, the raw material that the bad body is used for：50 parts of kaolin, 12 parts of aluminum oxide, silica
13 parts, 5 parts of bentonite, 4 parts of montmorillonite powder, 20 parts of volcano stone flour, 5 parts of carbon dust, 0.3 part of silver-series antibacterial agent；The glaze layer is used
Raw material be：8 parts of kaolin, 2 parts of bentonite, 4 parts of volcano stone flour, 5 parts of carbon dust, 5 parts of carborundum powder, 0.1 part of silver-series antibacterial agent,
5 parts of pigment.
As optimization, the carbon dust is bortz powder, and bortz powder can preferably improve the hardness and abrasion resistance of ceramics.Make
For further optimization, the granularity of the bortz powder is 100~300 nanometers.
Present invention also offers a kind of technique for preparing right wear-resistant antibacterial function ceramics, its processing step is：
(1) each raw material, is weighed respectively according to blank raw material proportioning, is added water simultaneously after then mixing bentonite, montmorillonite powder
Stirring expands and is completely dispersed to form suspension in water for 10~20 minutes completely to it, wherein, the water and blank raw material of addition
The ratio of gross weight is 1:0.8-1.2；
(2) it is placed in after, volcano stone flour is mixed with carbon dust in batch mixer and carries out batch mixing and take out and mixed after 10~30 minutes
Powder is closed, suspension is stirred 10~15 minutes, mixed-powder, silver-series antibacterial agent are sequentially added in whipping process and is resisted
Bacterium lime set；
(3), antibacterial lime set is carried out persistently to stir 30~50 minutes, continued in whipping process with 5~8 parts by weight per minute
Speed add the mixed-powder of kaolin, aluminum oxide and silica after form pug, pug, which shape, obtains ceramic thick
Base, carries out sharp base and obtains base substrate after drying in the shade naturally；
(4) each raw material, is weighed respectively according to glaze layer raw material proportioning, is added water, is stirred after then bentonite is mixed with kaolin
Mix 10~20 minutes and expanded completely to it and be completely dispersed to form suspension in water, continue to stir 10~30 minutes, it is stirred
Volcano stone flour, carbon dust, carborundum powder, silver-series antibacterial agent, pigment are sequentially added in journey and obtains glaze water, wherein, the water and glaze of addition
Layer raw material gross weight ratio is 3-5:1；
(5) glazing is carried out to base substrate using glaze water, the base substrate after glazing fired under conditions of 1150~1300 DEG C to 3~
Obtain wear-resistant antibacterial function ceramics within 15 hours.
The principle of present invention process step is：Bentonite, montmorillonite expand and scattered so as to form suspension in water
And with colloid clay characteristic, volcano stone flour and carbon dust are the extremely strong materials of adsorptivity, by the mixing of volcano stone flour and carbon dust
Powder and silver-series antibacterial agent, which are added in suspension, obtains antibacterial lime set, and lasting stirring can make the mixed powder point of volcano stone flour and carbon dust
Dissipate and do not settled in suspension, so that the silver-series antibacterial agent added by after is adsorbed and is suspended in obtained antibacterial lime set, it
Continue to add the mixed-powder of kaolin, aluminum oxide and silica with the speed of 5~8 parts by weight per minute in whipping process afterwards
After form pug, due to bentonite, the adsorptivity of the clay characteristic of montmorillonite formation suspension and volcano stone flour and carbon dust and
Continual whipping process so that the antiseptic in the pug so obtained is uniformly distributed, pug is carried out to shape
Sharp base is carried out to ceramic crude green body, after drying in the shade naturally and then obtains the base substrate with antibacterial functions.In addition, the base of this wear-resistant antibacterial ceramics
Volcano stone flour, carbon dust are added in body raw material in addition to playing the silver element in absorption silver-series antibacterial agent, can also be with kaolin, oxidation
The raw materials such as aluminium, silica are mutually promoted, and its effect be combined with each other and is superimposed, after comprehensive increase is fired the internal hardness of ceramics and
Toughness, so that ceramics have wearability after firing.
During glaze water is prepared, added water after bentonite is mixed with kaolin, fire is sequentially added while stirring afterwards
Mountain stone flour, carbon dust, carborundum powder, silver-series antibacterial agent, pigment obtain glaze water, and its principle is equally to utilize bentonite, montmorillonite shape
Into the clay characteristic and volcano stone flour and the adsorptivity and continual whipping process of carbon dust of suspension so that in glaze water
Carborundum powder, antiseptic and pigment are uniformly distributed.In addition, the wear-resisting principle of this wear-resistant antibacterial ceramics is to be added in glaze water
Volcano stone flour, carbon dust, carborundum powder, its effect be combined with each other and are superimposed, and can integrate the hardness of ceramic surface after increase is fired
With toughness so that fire after ceramics have super-high wear-resistant.
The antibacterial mechanisms of this wear-resistant antibacterial ceramics are that the main constituents of bacteria cell wall are peptide glycan, work as microorganism
It is attached to after ceramic surface, the silver ion in ceramics is applied directly on the cell membrane of bacterium into branch, suppresses polysaccharide chain and four
Peptide is crosslinked with linking, and cell membrane is lost integrality, loses the protective effect of cell membrane in itself, causes the death of bacterium, silver from
Son can also damage the cell membrane of microorganism, and cell membrane is the most important part of microbial life activity, cell membrane one it is single it is impaired,
Destruction will cause the death of bacterium, in addition, silver ion directly suppresses the synthesis of microprotein, cut off the life of microorganism
Chain, makes cell death, finally, silver ion can also interference cell nucleic acid synthesis, hinder microorganism hereditary information duplication, such as
Synthesis of the hereditary information such as DNA, RNA etc..
Preferably, the stir speed (S.S.) made in ceramic process step is 60~500r/min.As further excellent
Stir speed (S.S.) in choosing, the processing step (1) is 350~500r/min, and such quick stirring can make bentonite, montmorillonite
Abundant water swelling, so that the strong suspension of clay is made；Stir speed (S.S.) in the processing step (2) is 350~450r/
Min, can so be such that the mixed-powder of volcano stone flour and carbon dust is fully acted on by the clay of suspension, so as to be dispersed in outstanding
In supernatant liquid, its suction-operated to silver-series antibacterial agent is further played, so that silver-series antibacterial agent is uniformly distributed in antibacterial and coagulated
In liquid；Stir speed (S.S.) in the processing step (3) is 60~200r/min, can so obtain silver-series antibacterial agent distribution more equal
Even soup stock, after ceramics are made, silver-series antibacterial agent can play complete bactericidal action and be difficult to be consumed；The technique step
Suddenly the stir speed (S.S.) in (4) is 100~300r/min, obtains volcano stone flour, carbon dust, carborundum powder, silver system antibacterial under the conditions of this
The glaze water of agent, pigment distribution evenly.
