Abstract
The invention discloses a ceramic glaze with antibacterial capability and a preparation method of the ceramic glaze. The ceramic glaze with antibacterial capability is composed of the following components in percentage by weight: 57-61% of SiO2, 23-27% of Al2O3, 6-8% of CaO, 0.5-1% of K2O, 0.5-1% of Na2O, 1-3% of Li2O, 2-4% of ZnO, 1-2% of MgO, 2-3% of nano TiO2 and 1-2% of Ag. The preparation method of the ceramic glaze with antibacterial capability comprises the following steps of: mixing and crushing the components except nano TiO2 and Ag, carrying out wet ball milling until the fineness of the glaze slurry is 0.03-0.05 of standard screen residue to obtain the glaze slurry, then adding nano TiO2 and silver nitrate solution, uniformly mixing, applying on a biscuit, and firing at 790-800 DEG C to obtain the ceramic glaze with antibacterial capability. The obtained ceramic glaze with antibacterial capability has excellent antibacterial capability, and has Escherichia coli killing rate within 2h of more than 98%.
Description
Technical field
The invention belongs to the ceramic glaze technical field, be specifically related to a kind of ceramic glaze and preparation method thereof with antibacterial ability.
Background technology
The continuous enhancing of Along with people's health perception, people require to improve day by day to the cleaning of all kinds of affaires, adopt all ways to remove the bacterium on daily necessities surface in the life.Aspect domestic ceramics, the researchist adopts toward wherein adding and has the component of sterilization effect so that pottery has sterilizing function usually.Component with sterilization effect commonly used comprises silver suboxide and nano titanium oxide.
Summary of the invention
The object of the present invention is to provide a kind of ceramic glaze with antibacterial ability, said ceramic glaze with antibacterial ability adopts silver suboxide and nano titanium oxide combination, and its antibacterial ability is improved greatly.
Another object of the present invention is to provide said preparation method with ceramic glaze of antibacterial ability.
Above-mentioned purpose of the present invention is achieved through following technical scheme:
A kind of ceramic glaze with antibacterial ability, form by the component of counting by weight percentage as follows:
SiO
257 ~ 61%, Al
2O
323 ~ 27%, CaO 6 ~ 8%, K
2O 0.5 ~ 1%, Na
2O 0.5 ~ 1%, Li
2O 1 ~ 3%, and ZnO 2 ~ 4%, MgO1 ~ 2%, nano-TiO
22 ~ 3% Ag 1 ~ 2%.
Most preferably, said ceramic glaze with antibacterial ability is made up of the component of counting by weight percentage as follows:
SiO
257%, Al
2O
323%, CaO 6%, K
2O 1%, Na
2O 1%, Li
2O 3%, and ZnO 3%, MgO2%, nano-TiO
23% Ag 1%.
Said preparation method with ceramic glaze of antibacterial ability comprises the steps: removing nano-TiO
2Mixing with the component formula of Ag and to pulverize, carry out wet ball mill, is that 10000-hole sieve shines surplus to be 0.03 ~ 0.05, promptly to get glaze slip, add nano-TiO then to the glaze slip fineness
2And silver nitrate solution, after mixing, impose on the biscuit, under 790 ~ 800 ℃, fire, obtain said ceramic glaze with antibacterial ability.
The germicidal action and the nano-TiO of silver
2Difference, nano-TiO
2Be through at water and O
2Exist down, the process of illumination can discharge atomic oxygen and hydroxyl free radical, thus kill bacteria; Silver-colored then be to carry out sterilization through the silver ions that is dissolved in the water; TiO
2Sterilization effect rapid, but need stronger illumination, the sterilization effect of silver is slow, but required condition is simpler, therefore, the combination of the two can produce complementation, improves the antibacterial ability of product.
Nano titanium oxide of the present invention can perhaps adopt conventional preparation method to prepare through commercially available.
Compared with prior art, the present invention has following beneficial effect:
Ceramic glaze with antibacterial ability according to the invention has excellent antibacterial ability, in 2 hours, colibacillary sterilizing rate is reached more than 98%.
