A kind of Ceramic Tiles with color changeable effect and preparation method thereof
Technical field
The present invention relates to building decoration ceramic field, more particularly to a kind of Ceramic Tiles and its preparation side with color changeable effect
Method.
Background technology
Ceramic tile is in the home decoration in occupation of critically important part, and it is other that the ceramic tile combinations of different patterns can assign house fitting-up
The elegance of sample, gives the beautiful enjoyment of vision.With the development of Ceramic Tiles inkjet technology, the pattern of ceramic brick surface is rich
Richness, fine and smooth degree is obtained for great lifting, and in the market occurs in that the vivid and true to nature imitation wood line and imitative stone material of various quality
Ceramic Tiles, the sales volume of glazed tile obtained being also accumulated from large quantities of production glaze for glazed tile in the development of blowout, industry
Producer.Some problems are also brought simultaneously, it is all machine-made product that such as in the market, which is presented in face of consumer, it is current simple
Dependence layout it is less great to the lifting meaning of Ceramic Tiles, only pass through and develop personalized ceramic brick product
The growing demand of consumer could be met.
Color-change ceramic brick is to apply a kind of off-color material and ceramic brick surface, after high temperature is burnt till, can be in difference
Light under show the Ceramic Tiles of different colours., can be by combining based on this color changeable effect below different light
Layout, by controlling different light, realizes the changeable of Ceramic Tiles decoration style, lifts the personalization of Ceramic Tiles.China
Patent CN103693992A discloses a kind of changing colour enamal ceramics and its production method, this method by neodymia directly and some raw materials
Be mixed into camouflage paint, be then added to according to certain ratio among base glaze and changing colour enamal is made, then by spray or
Person pours to apply is made discoloration glazed tile in ceramic brick surface.Chinese patent CN104326739B discloses a kind of disilicic acid neodymium high temperature pottery
Porcelain color and preparation method thereof, the patent is prepared for the disilicic acid neodymium high temperature decorating colour with color changeable effect, and the colorant is in sunshine
It is down purple, is under fluorescent light blueness.The application example of existing color-change ceramic brick, is that neodymia is applied directly into glaze
In, it is primarily present problems with:First, the carbon dioxide in the easy moisture absorption of rare-earth oxidation neodymium, easy absorption air, by neodymia system
Into changing colour enamal, in sintering process, glaze easily bubbles, and has a strong impact on the quality of glaze;Secondly, neodymia easily with its in glaze
He reacts at composition, the glaze color developments of different systems not easy-regulating;Finally, directly using neodymia, its hair color effect is poor.
The content of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art there is provided a kind of Ceramic Tiles with color changeable effect and
Its preparation method.
The technical solution used in the present invention is:A kind of Ceramic Tiles with color changeable effect, it is from bottom to top by ceramic blank
Body layer, cover coat, glazed colour layer and transparent glaze layer composition, wherein glazed colour layer is mixed by discoloration fancy glaze and common fancy glaze, described
Discoloration fancy glaze is mixed by Nd silicide and the component of low-temperature solvent two.
As the further improvement of such scheme, the Nd silicide accounts for color-changing flower based on material quality percentage composition
The 1 ~ 50% of glaze solid phase composition.
As the further improvement of such scheme, the low-temperature solvent is according to the weight percentage of raw materials by 40.51 ~ 49.32%
SiO2, 7.50 ~ 11.32% Al2O3, 9.38 ~ 16.10% CaO, 3.58 ~ 7.39% MgO, 1.05 ~ 5.60% K2O and
7.35 ~ 10.27% ZnO compositions.
A kind of preparation method of the Ceramic Tiles as described above with color changeable effect, it is comprised the technical steps that:
1)Silica and neodymia are weighed according to a certain percentage, appropriate mineralizer and dispersant is added, and dry blended stirring is equal
Even rear high-temperature heat treatment, obtains Nd silicide;
2)Obtained Nd silicide is mixed with low-temperature solvent, dispersant and stamp-pad ink and is placed in ball-milling treatment in ball mill, mistake
Sieve, obtains discoloration fancy glaze;
3)Discoloration fancy glaze and common fancy glaze are needed to carry out mixing toning according to design, and printed by screen printing or roller
Colored mode charity is being had been coated with the ceramic body of cover-coat enamel, forms glazed colour layer, then charity clear frit on glazed colour layer again, after
Through drying, burn till, obtain the Ceramic Tiles with color changeable effect.
Wherein, step 3)Described common fancy glaze needs to allocate according to design to be formed, in general practical operation
Can by common colorant with print cream, after stamp-pad ink mixing and ball milling certain time through sieving processing obtain common fancy glaze.
It is used as the further improvement of such scheme, step 1)Described in silica be according to mol ratio with neodymia
2.5~4:2 mixing.Yet further, the particle diameter of silica and neodymia is 20 ~ 100nm, and it is conducive to efficiently synthesizing knot
The high Nd silicide of brilliant degree.
It is used as the further improvement of such scheme, step 1)Described in mineralizer in boric acid and borax at least one
Kind, its addition is the 1 ~ 4% of silica and neodymia gross mass.
It is used as the further improvement of such scheme, step 1)Described in dispersant be containing hydrogen silicone oil, its addition be two
The 0.3 ~ 0.5% of silica and neodymia gross mass.Containing hydrogen silicone oil is added in the present invention as dry-mixed dispersant, can effectively be reduced
The reunion caking of Nd silicide, so as to further improve the stability of glaze layer after charity.
It is used as the further improvement of such scheme, step 1)Described in heat treatment process in control temperature 1150 ~
In the range of 1350 DEG C, soaking time is 1 ~ 3h.
It is used as the further improvement of such scheme, step 2)Described in dispersant to be selected from sodium tripolyphosphate and carboxymethyl fine
At least one of plain sodium of dimension, its addition is the 0.1 ~ 0.5% of Nd silicide and low-temperature solvent gross mass.
It is used as the further improvement of such scheme, step 2)Middle to require that discoloration fancy glaze crosses 325 mesh sieves without tailing over, its proportion is
1.3~2.2g/cm2。
It is used as the further improvement of such scheme, step 3)In firing temperature be 1150 ~ 1290 DEG C.
The beneficial effects of the invention are as follows:The present invention regard the Nd silicide with high-temperature stable crystal formation as discoloration fancy glaze
Principle active component, becomes apparent from its colour generation and color changeable effect, by charity after the discoloration fancy glaze and common fancy glaze compounding in ceramics
The glazed colour layer formed on brick, has the advantages that glaze quality is good, color changeable effect is notable, chromophoric characteristic is stable.The present invention prepares work
Skill is simple, is conducive to large-scale industrial production.
