Moreover, in order to create a gorgeous color effect, the glossiness of the surface of the colorful glazed tile is higher.
In the production process of ceramic tiles, there are three possible processes for producing colorful glazed tiles-archaized tiles, polished tiles and full-glazed tiles. Wherein, the surface gloss of the archaized brick is low, and the requirement of decoration is difficult to meet; when the polished brick is produced by adopting the polished brick process, the polished brick is generally produced by adopting a technical scheme of two layers of blanks. Specifically, during material distribution, a layer of white blank (without decoration color blank) is distributed, and then a color material layer is distributed on the white blank layer; the glaze is not applied after the pressing, and the drying and the sintering are directly carried out. However, since the colorful glazed tile has rich colors, a large amount of pigment needs to be added to the surface layer, which often causes the problems of increased firing temperature and unmatched pigment layer and green body layer, and various defects are easily caused; the fired pigment layer generally has a thickness of 3 to 5mm and a thickness of 8 to 15mm in the case of fabric. So that the full-polishing glaze process is mostly adopted to produce colorful glazed tiles at present.
When the fully-glazed brick is produced by adopting a full-glazed brick process, a technical scheme of decorating by adopting a white blank body (a blank body without decoration color) and a glaze layer (0.2-1 mm) is generally adopted. Specifically, the decorative pattern is printed on the surface of the blank by screen printing or ink jet printing, but the colorful glazed tile is colorful, so that a large amount of ink is consumed, and the production cost is very high.

specifically, the fabric powder materials with various colors are respectively placed in different hoppers, and are fed through a plurality of channels to be distributed on the bottom material layer. In the blanking process, a fabric layer pattern (first pattern) is formed by controlling the blanking amount, blanking position and the like of different fabric powder materials. It should be noted that, because the whole color of the glazed colorful tile is quite rich, the boundary between different colors is not very obvious and good. Therefore, the fabric layer pattern formed by the cloth can be well matched with the decorative layer pattern formed by the later-stage ink-jet printer.
Specifically, a 6-8 channel material distributor is adopted to distribute the fabric powder material to form a fabric layer. After the cloth is distributed, the thickness of the fabric layer is 1-5 mm; when the thickness of the fabric is more than 5mm, the pigment in the fabric layer is too much, so that the brick shape is difficult to control, uneven glaze surface is easy to appear, and the decorative effect is influenced. When the thickness of the fabric is less than 1mm, the color development of the fabric pattern is not enough, and the fabric pattern is difficult to be matched with the pattern of the decorative layer at a later stage. Preferably, the thickness of the fabric layer is 1-3 mm.
It should be noted that, the traditional secondary material distribution process is generally applied to polished tiles, namely, a base material layer is firstly distributed, and then a fabric layer is distributed, wherein the thickness of the fabric layer is generally controlled to be 8-15 mm; when the binder layer contains a large amount of the coloring material, the firing temperature is likely to rise, and the problem of mismatching between the binder layer and the green body layer is likely to occur. Another conventional production process is to apply a secondary distribution process to inkjet tile, which is also essentially polished tile. When the ink-jet flower-penetrating brick is used for secondary cloth fabric, in consideration of the color development effect of flower penetration, the surface layer powder is generally crushed and distributed in the form of micro powder (the residue of a 100-mesh sieve is less than 20 wt%), and the thickness of the cloth is usually controlled to be 5-10 mm due to poor flowability of the micro powder and in order to prevent the bottom layer powder from puncturing the surface layer powder in the pressing process. On the one hand, the powder particles are larger and have strong fluidity; the thickness of the fabric layer can be effectively reduced by adopting the forward beating process; on the other hand, the function of the fabric layer pattern in the invention is that the fabric layer pattern is matched with the decorative layer pattern, the ink-jet printed pattern does not penetrate, the action mechanism is different, and the thickness is different.
S6: pressing the powder aggregate to obtain a green body;
in the pressing process, the pressing pressure is 30-50 MPa.
Specifically, after pressing, the thickness of the fabric layer is 0.4-2 mm, and the thickness of the primer layer is 8-12 mm.
S7: forming a mark on the side surface of the green body;
specifically, a laser marking machine may be used to apply a mark to the side of the green body.
The marks correspond to the pattern information one by one; i.e. one kind of decorative pattern information corresponds to one kind of mark.
S8: drying the green body, and applying a base coat;
specifically, the green body is dried through a drying kiln, and the highest temperature of the drying kiln is 180-300 ℃.
And after drying, spraying a base glaze on the green body.
S8: reading the mark, and carrying out ink-jet printing on the decorative layer on the ground glaze layer according to the pattern information corresponding to the mark;
specifically, before inkjet printing, the mark is read by an identification device; the ink-jet printer prints according to the fabric layer decorative pattern (first decorative pattern) determined by the mark to form a decorative layer with a second decorative pattern. Wherein, the first decorative pattern is the same as the second decorative pattern. The same decorative pattern means that the degree of overlap between the first decorative pattern and the second decorative pattern is 80% or more.
In particular, the indicia are read by an identification device, which may optionally be a photosensor, such as but not limited to a loose FP-X series photosensor.
Specifically, after the identification device reads the mark, the mark is converted into an electric signal, and then an ink-jet printer is controlled to print a decorative layer pattern on the surface of the green body, wherein the decorative layer pattern is the same as the pattern of the fabric layer. The decorative pattern of the colorful glazed tile is formed by superposing and supporting the decorative layer pattern and the fabric layer pattern. This greatly saves the consumption of ink in the ink-jet printing process, and the ink-jet printing ink of the invention can be saved by more than 70%.
S10: applying a cover glaze on the decorative layer;
s11: firing the green body to obtain a finished product of the colorful glazed tile;
preferably, the preparation method of the invention further comprises the following steps:
