Abstract
The present invention relates to a process for producing photocatalytic antibiotic ceramics, which has the process steps: the ceramics are firstly coated with glaze; after a glaze surface is formed, a coating procedure is started, and a photocatalyst is sprayed on the ceramics; and finally, the ceramics enter a calciner to be burned. The production process can ensure the lasting and potent combination of the photocatalyst and base material and can also ensure the antibiotic capability of a photocatalytic film. The experiments verify that the photocatalytic film has no visible influence on strips, patterns and colors of a product. In addition, a ceramic surface with the photocatalytic film is smooth and flat. The bonding force of the photocatalytic film and the glaze surface is as high as 61N. Under the light of a fluorescent lamp of 8W, ceramics with the photocatalytic film have 90.23% of antibiotic rate to staphylococcus aureus and have 87.06% of antibiotic rate to colibacillus.
Description
Technical field
The present invention relates to a kind of photocatalysis antibacterial ceramic production technology.
Background technology
At present, in building trade, architectural pottery particularly inner-wall ceramic tile has been introduced indoor as finishing with material in a large number.Indoor environment, because dark moist, ventilation is smooth and contain rich nutrient substances as places such as kitchen, toilet, Operation theatre, wards, the utmost point is beneficial to harmful microbe and grows, breeds and propagate.Inner-wall ceramic tile is the good carrier of bacterium, virus often, is the important carrier of all kinds of cross-infections.Each bacterioid of ceramic tile surface can effectively be killed or be suppressed to colonize in to the photocatalysis antibacterial technology of rising in recent years.Testing at present the technology with the antimicrobial ceramic product of small serial production, can be divided into dual mode: a kind of production technique is (as nano-TiO with photocatalyst
2) mix with the glaze class, disposable calcining is become a useful person; Another kind of production technique is at the spraying of finished bricks surface catalyst pulp, sintering once more.First kind of production technique is because the sedimentation of catalyst particles and glaze to the part embedding of catalyzer, and have significantly reduced the antibacterial ability of catalytic film; The second kind of production technique not only bonding force of catalytic film and ground is relatively poor, and double sintering increased energy consumption, has reduced production efficiency.
Summary of the invention
The object of the present invention is to provide a kind of both capable of reducing energy consumptionly, can enhance productivity again, and can guarantee the photocatalysis antibacterial ceramic production technology of mortise between the high anti-microbial activity of catalytic film and film and ground.
In order to achieve the above object, technical program of the present invention lies in having adopted a kind of photocatalysis antibacterial ceramic production technology, its processing step is as follows: pottery is coated with glaze through being coated with the glaze operation earlier, after the glaze moulding, enter filming process and carry out the spraying of photocatalyst, enter calcining furnace at last again and fire.
Described photocatalyst spray coating liquor is by nano-TiO
2Colloidal sol and account for nano-TiO
2The loaded TiO of the 2-3% of sol volume percentage composition
2Fine catalyst is formed.
Because production technique of the present invention is that pottery is coated with glaze through being coated with the glaze operation earlier, after the glaze moulding, enter filming process and carry out the spraying of photocatalyst, entering calcining furnace at last again fires, so both guarantee lasting strong the combining of photocatalyst and ground, also guaranteed the antibacterial ability of photocatalysis membrana.Experimental results show that, catalytic film does not have visible influences to decorative pattern, pattern, the color and luster of product, and the coated cermet surface is more smooth smooth, through relevant professional unit testing, catalytic film and glaze bonding force are up to 61N, coated cermet is 90.23% to the antibiotic rate of streptococcus aureus under the fluorescent lamp of 8W, is 87.06% to colibacillary antibiotic rate.
