Abstract
The utility model provides a photocatalytic ceramic with adjustable surface glossiness, which comprises a ceramic body and is characterized in that the surface of the ceramic body is coated with a photocatalytic film with adjustable surface glossiness. The photocatalytic ceramic has reasonable structure, adjustable glossiness, self-cleaning property, and good air purifying, sterilizing and decorating effects.
Description
Technical field
The utility model relates to a kind of photocatalysis ceramics of adjustable surface gloss, but particularly encloses the nano-photo catalytic film of one deck adjustable surface gloss at conventional ceramic product surfaces such as ceramic tile, china sanitary ware, crockeries.
Background technology
Ceramic product is widely used in building, decoration and the daily life, and the difference of environment for use can be brought pollutions such as dirt, germ and stink to ceramic surface, and the ceramic product of developing functions such as having automatically cleaning, antibiotic is significant.In recent years, people utilize the photochemical catalytic oxidation and the photic hydrophilicity of titanium dioxide, it is coated in material surface has developed many functional materials, as automatically cleaning outdoor tile, self-cleaning glass curtain wall, antibiotic sanitary equipment etc., these materials have been applied to places such as building, kitchen, office and hospital.For example, the outdoor tile that scribbles coating of titanium dioxide can be given and gives buildings with automatically cleaning and performance such as purify air.Yet the optically catalytic TiO 2 coating usually causes the variation of ceramic outward appearance, thereby influences the ornamental of product.This appearance effects depends primarily on the preparation method of masking liquid.We once utilized sol-gel method to develop TiO 2 sol type photocatalyst, though this photocatalyst coating can form layer of transparent, colourless film at ceramic tile surface, and the variation that can the surface bring glossiness.Consider the decorative function of material of construction, need to keep the consistence of photocatalysis ceramics product surface glossiness for this reason.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of photocatalysis ceramics of adjustable surface gloss, and this product glossiness not only rational in infrastructure can be regulated, but and automatically cleaning, purify air, sterilization, good decorating effect.
The utility model comprises ceramic body, it is characterized in that: described surface of ceramic body is coated with the photocatalysis membrana of adjustable surface gloss joint.
The utility model not only makes ordinary light catalytic ceramics product have automatically cleaning, purify air and function such as antibiotic, can keep the consistence of product appearance by the glossiness of regulating product surface simultaneously, thereby guarantees the decorative function of product.
Description of drawings
Below in conjunction with the description of accompanying drawing to embodiment, further describe the concrete structure of the utility model ceramic product, wherein:
Fig. 1 is the view of the utility model broken section.
1. ceramic product bodies among the figure, the 2. adjustable photocatalysis thin film of glossiness
Embodiment
The utility model comprises ceramic body 1, it is characterized in that: described surface of ceramic body is coated with the photocatalysis membrana 2 of adjustable surface gloss joint, photocatalysis thin film closely is coated in the conventional ceramic product surface, and the adjusting of surface gloss is realized by the pH value that changes the liquid photocatalyst that forms photocatalysis thin film.
The glossiness of photochemical catalysis ceramic tile can realize by the liquid photocatalyst that applies different pH values.Table 1 is the surface gloss of photochemical catalysis ceramic tile and the relation of liquid photocatalyst pH value.As can be seen, behind the common matt porcelain brick surface-coated photocatalysis thin film, surface gloss obviously raises.Along with the rising of pH value, the glossiness of ceramic tile surface descends gradually, but is between 2.0～3.0 in the pH value, and the ceramic tile surface glossiness changes, and this explanation is controlled at liquid photocatalyst pH value in this scope, easily obtains the more consistent photochemical catalysis ceramic tile of surface gloss.
Table 1: the relation of ceramic tile surface glossiness and liquid photocatalyst pH value
| The pH value | 1 .69 | 2 .02 | 2 .10 | 2 .40 | 2 .60 | 2 .81 | 3 .02 | 3 .21 | 3 .40 | 3 .65 |
| Glossiness | 9 0.2 | 7 1.2 | 6 6.0 | 6 5.6 | 6 3.8 | 6 2.5 | 6 2.3 | 6 0.8 | 5 6.7 | 4 9.7 |
Annotate: not applying the preceding matt porcelain brick surface gloss of photocatalysis thin film is 32.0.
Above-mentioned photocatalysis thin film can utilize modes such as spraying, brushing and dip-coating to combine closely on the ceramic product surface.
The utility model is novel, designs ingeniously, helps the market large-scale popularization and uses.
