Definitions
- the present invention relates to a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate.
- the reserving compositions are applied to the surface of ceramic manufactured articles, resulting in the formation of a three-dimensional structure.
- the application of reserving composition is often synchronized with the realization of graphic elements and other aesthetic effects, so as to increase the material effect, as well as the three- dimensional feature and depth of the graphics.
- known reserving compositions comprise a mixture of silicon-based compounds generally present in a concentration by weight, evaluated with respect to the total weight of the composition, of less than 50% and one or more organic solvents.
- Such reserving compositions have a mild hydrophobic effect due to the presence of a low concentration of silicon-based compounds.
- a mild hydrophobic effect is matched by a mild structuring power and, therefore, an unsatisfactory material effect.
- organic solvents increases the production of volatile organic compounds and/or compounds that are harmful to people’s health, such as, e.g., aldehydic and benzene compounds, or compounds with high odorigenic power.
- reserving compositions have low lubricating power, which causes them to accumulate on the dispensing nozzles of digital printers, thus leading to fouling on their edges and damaging the print head.
- the main aim of the present invention is to devise a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate that allows greatly improving the hydrophobic effect and, consequently, the textural effect of the surface structure of the manufactured article itself.

- the process comprises a phase of applying a backing layer of a ceramic ink.
- the backing layer comprises at least one of a glaze, an engobe or a more stratified version called “smaltobbio”.
- the backing layer allows the color of the ceramic mixture to be covered, thus optimizing the color development of the ceramic ink and resulting in the reduction of gaseous emissions from the mixture during the firing of the raw ceramic manufactured article and/or of the semi-finished product.
- the process comprises a phase of applying the ceramic ink to the raw ceramic manufactured article or to the ceramic semi-finished product or to the agglomerate.
- the hydrophobic effect due to the synergistic combination of the first silicon-based component, preferably linear siloxane, and of the second cyclic siloxane component allows the ceramic ink to be applied in a complementary manner with respect to the portions of the raw ceramic manufactured article or of the semi-finished product or of the agglomerate covered by the reserving composition.
- the ceramic ink deposition is carried out in such a way as to maximize the color contrast between the portions of the ceramic manufactured article having such three-dimensional structures.
- the application of a ceramic ink having a dark color, such as black, within the grooves will result in the increased perception of depth by an observer.
- the process comprises one phase of laying a protective layer on the raw ceramic manufactured article or on the ceramic semi-finished product or on the raw agglomerate, wherein said protective layer comprises glass grits and/or a glaze.
- Glass grits can be applied by two different modes, a first wet mode and a second dry mode.

- the suspension may comprise one or more inorganic components selected from the list comprising: feldspars, alkaline metal carbonates, alkaline earth metal carbonates, quartz, alumina, clays, geopolymers and talc.
- the second mode of glass grit application i.e., dry, involves the latter being applied to an adhesive layer laid on the raw ceramic manufactured article or on the ceramic semi-finished product or on the agglomerate.
- the glass grits are sandwiched between two adhesive layers applied to the raw ceramic manufactured article or to the ceramic semi-finished product or to the agglomerate.
- a second embodiment of the process according to the invention involves the latter continuing to comprise the phases of making available a raw ceramic manufactured article or a ceramic semi-finished product or a raw agglomerate, applying the reserving composition and firing the raw ceramic manufactured article or the ceramic semi-finished product or the raw agglomerate so as to obtain a ceramic manufactured article, or an agglomerate, that is superficially structured and has one or more grooves and/or one or more reliefs.
- the process also continues to comprise the phase of applying a ceramic ink and optionally of laying a layer of protective material.
- the phase of applying the reserving composition is carried out after the application of the ceramic ink.
- This expedient allows for greater production flexibility as it enables the reserving composition to be dispensed at the ending phase of the manufacturing process of the ceramic manufactured article or of the agglomerate, allowing for upstream changes in the decoration phases of the manufactured article itself.
- the fact that the reserving composition is applied subsequently to the ceramic ink allows the composition to be used to make inorganic compounds and/or colorants adhere as well as glass grits.
- a layer of protective material is applied after the application of the reserving composition.
- the firing phase is carried out at a temperature above 650°C. More preferably, the firing phase is carried out at a temperature of 1130°C to 1250°C.
- a third embodiment of the process according to the invention involves the latter continuing to comprise the phases of making available a raw ceramic manufactured article or a ceramic semi-finished article or an raw agglomerate, applying the reserving composition and firing the raw ceramic manufactured article or the ceramic semi-finished article or the raw agglomerate so as to obtain a ceramic manufactured article, or an agglomerate, that is superficially structured and having one or more grooves and/or one or more reliefs.

Description
RESERVING COMPOSITION FOR THE SURFACE STRUCTURING
OF A CERAMIC MANUFACTURED ARTICLE AND/OR OF AN AGGLOMERATE
Technical Field
The present invention relates to a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate.
Background Art
With reference to the field of decoration of ceramic manufactured articles, it is well known that in recent years the use of reserving compositions adapted to vary the surface morphology of manufactured articles has found widespread use.
The reserving compositions are applied to the surface of ceramic manufactured articles, resulting in the formation of a three-dimensional structure.
Thanks to the spread of digital technology, the application of reserving composition is often synchronized with the realization of graphic elements and other aesthetic effects, so as to increase the material effect, as well as the three- dimensional feature and depth of the graphics.
Specifically, known reserving compositions comprise a mixture of silicon-based compounds generally present in a concentration by weight, evaluated with respect to the total weight of the composition, of less than 50% and one or more organic solvents.
Such reserving compositions have a mild hydrophobic effect due to the presence of a low concentration of silicon-based compounds.
A mild hydrophobic effect is matched by a mild structuring power and, therefore, an unsatisfactory material effect.
In fact, known reserving compositions do not allow for aesthetically defined and tactile satisfactory surface structures.
In addition, the presence of organic solvents increases the production of volatile organic compounds and/or compounds that are harmful to people’s health, such as, e.g., aldehydic and benzene compounds, or compounds with high odorigenic power.
Again, such reserving compositions have low lubricating power, which causes them to accumulate on the dispensing nozzles of digital printers, thus leading to fouling on their edges and damaging the print head.
Description of the Invention
The main aim of the present invention is to devise a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate that allows greatly improving the hydrophobic effect and, consequently, the textural effect of the surface structure of the manufactured article itself.
One object of the present invention is to devise a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate that allows for a more defined surface structure than the use of known reserving compositions.
Still one object of the present invention is to devise a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate that allows obtaining high lubricating power compared to known reserving compositions.
Another object of the present invention is to devise a reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate that can overcome the aforementioned dunfiredbacks of the prior art within the framework of a simple, rational, easy and effective to use as well as cost-effective solution.
The aforementioned objects are achieved by this reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate having the characteristics of claim 1.
Furthermore, the aforementioned objects are achieved by the use of the reserving composition for the surface structuring of a ceramic manufactured article and/or of an agglomerate having the characteristics of claim 13.
Additionally, the aforementioned objects are achieved by the process for the surface structuring of a ceramic manufactured article and/or of an agglomerate having the characteristics of claim 15.

In a second aspect, the present invention relates to the use of the composition according to the invention for making one or more three-dimensional structures on the surface of a ceramic manufactured article or of an agglomerate, preferably a ceramic tile.
Advantageously, the one or more three-dimensional structures comprise one or more reliefs and/or one or more grooves having a thickness of between 0.05 mm and 3 mm.
In a further aspect, the present invention relates to a process for the surface structuring of a ceramic manufactured article or of an agglomerate, comprising the phases of: making available a raw ceramic manufactured article, or a ceramic semifinished product or a raw agglomerate; applying the reserving composition; firing the raw ceramic manufactured article or the ceramic semi-finished product or the raw agglomerate at a temperature of more than 150°C so as to obtain a ceramic manufactured article or an agglomerate having on its
surface one or more grooves and/or one or more reliefs reproducing a material effect.
It is specified that in the context of this disclosure the expression “ceramic semi-finished product” relates to a partly worked ceramic manufactured article, such as a biscuit.
Furthermore, it is specified that the expressions “raw ceramic manufactured article”, “ceramic semi-finished product” and “raw agglomerate” refer both to the fact that the same have undergone a pressing phase and to the fact that they have undergone a pressing and drying phase.
Preferably, the reserving composition is applied by means of digital ink-jet printing in an amount of between 0.1 g/m2 and 80 g/m2.
Advantageously, the process may comprise, prior to the firing phase of the raw ceramic manufactured article or the ceramic semi-finished product or agglomerate, a drying phase of the reserving composition.
In more detail, the drying phase is carried out prior to the phase of applying the reserving composition to the raw ceramic manufactured article or the ceramic semi-finished product or agglomerate.
It cannot however, be ruled out from the scope of this disclosure that the drying phase be carried out subsequently to the phase of applying the reserving composition on the raw ceramic manufactured article or the ceramic semifinished product or agglomerate.
In detail, the drying phase is carried out by means of a drying device until the raw ceramic manufactured article or ceramic semi-finished product or agglomerate has a temperature substantially below 200°C.
The drying phase lasts between 1 and 360 minutes.
In accordance with a first embodiment, following the application of the reserving composition, the process comprises a phase of applying a backing layer of a ceramic ink.
In detail, the backing layer comprises at least one of a glaze, an engobe or a more stratified version called “smaltobbio”.
Advantageously, the backing layer allows the color of the ceramic mixture to be
covered, thus optimizing the color development of the ceramic ink and resulting in the reduction of gaseous emissions from the mixture during the firing of the raw ceramic manufactured article and/or of the semi-finished product.
At this point, following the application of the reserving composition and of the backing layer, the process comprises a phase of applying the ceramic ink to the raw ceramic manufactured article or to the ceramic semi-finished product or to the agglomerate.
It is of paramount importance to emphasize that the application of the reserving composition, prior to the ceramic ink, does not affect the efficiency thereof and the quality of laying on the surface of the raw ceramic manufactured article or of the ceramic semi-finished product or agglomerate.
In fact, the hydrophobic effect due to the synergistic combination of the first silicon-based component, preferably linear siloxane, and of the second cyclic siloxane component allows the ceramic ink to be applied in a complementary manner with respect to the portions of the raw ceramic manufactured article or of the semi-finished product or of the agglomerate covered by the reserving composition.
This means that depending on the color of the ceramic ink, the application of the latter within the grooves will allow its depth effect to be increased or decreased.
To this end, in order to emphasize the material aesthetic effect brought about by the presence of reliefs and/or grooves, the ceramic ink deposition is carried out in such a way as to maximize the color contrast between the portions of the ceramic manufactured article having such three-dimensional structures.
For example, the application of a ceramic ink having a dark color, such as black, within the grooves will result in the increased perception of depth by an observer.
Finally, the process comprises one phase of laying a protective layer on the raw ceramic manufactured article or on the ceramic semi-finished product or on the raw agglomerate, wherein said protective layer comprises glass grits and/or a glaze.
Glass grits can be applied by two different modes, a first wet mode and a second dry mode.
The first mode of glass grit application, i.e., wet, involves the grits being suspended in an aqueous medium and applied by an ink-jet printer or, alternatively, by curtain, bell or airless systems.
Advantageously, the suspension may comprise one or more inorganic components selected from the list comprising: feldspars, alkaline metal carbonates, alkaline earth metal carbonates, quartz, alumina, clays, geopolymers and talc.
At the same time, the second mode of glass grit application, i.e., dry, involves the latter being applied to an adhesive layer laid on the raw ceramic manufactured article or on the ceramic semi-finished product or on the agglomerate.
In turn, it cannot be ruled out that the application of glass grits is followed by a further application of an additional adhesive layer.
In more detail, the glass grits are sandwiched between two adhesive layers applied to the raw ceramic manufactured article or to the ceramic semi-finished product or to the agglomerate.
A second embodiment of the process according to the invention involves the latter continuing to comprise the phases of making available a raw ceramic manufactured article or a ceramic semi-finished product or a raw agglomerate, applying the reserving composition and firing the raw ceramic manufactured article or the ceramic semi-finished product or the raw agglomerate so as to obtain a ceramic manufactured article, or an agglomerate, that is superficially structured and has one or more grooves and/or one or more reliefs.
The process also continues to comprise the phase of applying a ceramic ink and optionally of laying a layer of protective material.
In contrast to the first embodiment of the process in accordance with the present invention, the phase of applying the reserving composition is carried out after the application of the ceramic ink.
This expedient allows for greater production flexibility as it enables the
reserving composition to be dispensed at the ending phase of the manufacturing process of the ceramic manufactured article or of the agglomerate, allowing for upstream changes in the decoration phases of the manufactured article itself.
In addition, the fact that the reserving composition is applied subsequently to the ceramic ink allows the composition to be used to make inorganic compounds and/or colorants adhere as well as glass grits.
Alternatively, a layer of protective material is applied after the application of the reserving composition.
Finally, preferably, the firing phase is carried out at a temperature above 650°C. More preferably, the firing phase is carried out at a temperature of 1130°C to 1250°C.
A third embodiment of the process according to the invention involves the latter continuing to comprise the phases of making available a raw ceramic manufactured article or a ceramic semi-finished article or an raw agglomerate, applying the reserving composition and firing the raw ceramic manufactured article or the ceramic semi-finished article or the raw agglomerate so as to obtain a ceramic manufactured article, or an agglomerate, that is superficially structured and having one or more grooves and/or one or more reliefs.
Unlike in the first embodiment of the process in accordance with the present invention, the phase of applying the backing layer is carried out prior to the application of the reserving composition.
This expedient makes it possible to homogenize the application surface of the reserving composition, enabling stringent control of the surface structuring of the manufactured article to be carried out.
Next, the process comprises a phase of applying an auxiliary backing layer, the phase of applying an auxiliary backing layer being subsequent to the application of the reserving composition. This means, that the surface of the raw ceramic manufactured article or of the ceramic semi-finished product or of the raw agglomerate is characterized by the presence of an important layering consisting of the backing layer, the reserving composition and the auxiliary backing layer.
Advantageously, the auxiliary backing layer may have the same composition as
the backing layer, or different from the latter.
Preferably, the auxiliary backing layer comprises at least one of a glaze, an engobe or a more stratified version called “smaltobbio”.
At this point, the process in accordance with the present invention continues in a manner similar to the previous embodiments, that is, it involves the phase of applying the ink and the phase of laying the protective layer.
In a further aspect, the present invention relates to a superficially textured ceramic manufactured article or an agglomerate obtainable by the previously described process.
It has in practice been ascertained that the described invention achieves the intended objects.
It is emphasized that the special expedient of employing the synergistic combination of a first silicon-based component with a second cyclic siloxane component allows obtaining a surface structuring of the ceramic manufactured article, preferably a ceramic tile, having an improved definition with respect to the use of known reserving compositions.
In detail, the hydrophobic feature of the siloxane mixture together with the different surface tension of the same with respect to ceramic inks and/or other water-based components prevents the layered deposition thereof, thus allowing the formation of a three-dimensional structure.
