Description
Technical field
The present invention relates to degradation of formaldehyde ceramic tile preparation field, especially a kind of durability degradation of formaldehyde Dali stone ceramic tile and its
Preparation method.
Background technique
Currently the research about the degradation of formaldehyde technology of ceramic tile also has much, can substantially be divided into three classes, and one kind is that will have
There are the nano-titanium dioxide of photocatalytic effect or nanometer Zinc oxide powder to be added in glaze to fire together, on this method surface
It is to solve the problems, such as function durability, but can crystal transfer occur after firing due to high temperature and fail, and nano material
Mixing with glaze causes it largely to reunite, also its performance of further loss；It is exactly secondary firing there are also one kind, by the porcelain after firing
The presoma of the uniform titanium dioxide coating in brick surface, then calcining obtains expected crystal form, this method within specified temperatures
Can be obtained the degradation of formaldehyde tile product for having certain effect under ultraviolet light conditions, but this kind of ceramic tile cannot subsequent polishing waxing,
Antifouling and ceramic tile surface effect is all difficult to take into account, simultaneously because needing film and secondary firing, considerably increases production cost；Most
Latter class is directly to coat one layer of photocatalyst before ceramic tile is packaged, and this method operating procedure is simple, will not influence ceramic tile
All other performances, but since ceramic tile is largely wet look, photocatalyst particle can not be firmly bonded on ceramic tile, therefore be lost
The value of actual use.Therefore, these three types of technologies do not realize industrial application in ceramic industry, only reside within experiment
Room conceptual phase.
Summary of the invention
Based on this, a kind of durability degradation is provided it is an object of the invention to overcome above-mentioned the deficiencies in the prior art place
The preparation method of formaldehyde Dali stone ceramic tile.The present invention is directed to the photocatalyst with visible light activity is firmly bonded to marble porcelain
On brick, while not influencing Dali stone ceramic tile original performance, the function of Dali stone ceramic tile degradation of formaldehyde was not only imparted, but also can be real
The durability of this existing function.
