Definitions
- the present invention relates to the use of precipitated silica in dispersed form as a raw material for obtaining a dye by mixing said silica with an inorganic pigment, in particular with an inorganic pigment based on an iron compound. .
- a dye capable of being obtained by calcination, then optional grinding, of a mixture of precipitated silica in dispersed form and of an inorganic pigment, in particular of an inorganic pigment based on an iron compound. It also relates to the use of such a dye for coloring ceramic materials, and to the ceramic materials thus colored.
- Natural or synthetic pigments are used as colorants in the ceramic industry, in particular for the production of traditional colored tiles and tiles.
- the coloring is carried out by the addition of specific pigments to the ceramic paste before the shaping by pressing and sintering of the tiles / tiles obtained.
- Classic pigments for ceramics are natural products. So the
- Thiviers sandstone generally comprising approximately 90% of quartz and approximately 10% of goethite (FeOOH), makes it possible to obtain colors from red to brown which are the main colors developed traditionally for tiles and especially floor tiles, and in particular porcelain stoneware tiles (Porcellenato Stoneware) obtained using a “fast firing” process.
- a new concept of dye for ceramic materials has recently appeared: it consists in previously including the pigment in a mineral matrix, more particularly silica.
- the potential advantage of including the pigment in an inert vitreous or crystallized matrix is the great stability with respect to severe thermal and chemical conditions, such as those encountered in the ceramic industry, and has thus made it possible the development of new coloring powders.
- this dye acts as a chromatic unit from a pigmentation point of view and the color is not developed by introduction of an ion into the lattice of the matrix or by formation of a solid solution; the crystals responsible for coloring are in fact small crystals included during the cooking / sintering process of the matrix.
- This new concept is the synthesis of red / brown inorganic pigments for ceramic applications, by inclusion of hematite ( ⁇ -Fe 2 0 3 ) in a silica matrix.
- a dye made from microsilica (or silica fume) and iron oxide is described in WO 00/53680: the process uses intensive grinding in a humid environment, drying, high temperature calcination and grinding.
- the mixture between silica and iron oxide must be perfect. This implies for example that the silica powder is extremely well disaggregated by intensive grinding in order to obtain agglomerates having a size close to or less than that of the iron pigment, that is to say a few microns.
- the intensive contact of silica with the pigment is of great importance in the formation of color, in particular for obtaining a high level of red, a high gloss and a high intensity (red / brown after cooking). This is particularly the case in the presence of intensive grinding of the constituents.
- One of the aims of the present invention is to provide an alternative to the techniques known from the prior art, while dispensing with an intense grinding step and while making it possible, in particular, to achieve very good colorimetric performance. (in particular high stability), and avoiding the drawbacks mentioned above.
- the invention firstly relates to the use of precipitated silica (advantageously amorphous) in dispersed form (in water) as a raw material for obtaining a dye by mixing said silica with a inorganic pigment.
- Said inorganic pigment is preferably based on a metallic compound (for example a soluble metallic salt), and, even more preferably, based on an iron compound.
- This iron compound is generally chosen from Fe 2 0 3 , Fe 3 0 4 , FeOOH, a soluble iron salt or their mixtures. It can thus consist of iron oxide powder Fe 2 0 3 , Fe 3 0 4 or iron hydrate FeOOH. It is also possible to use one (or more) soluble iron salt (s), such as soluble iron nitrate (in the form of powder or solution), preferably soluble iron sulphate (in the form of powder or solution).
- precipitated silica is understood to mean any silica obtained by the precipitation reaction of a silicate, such as an alkali metal silicate (sodium silicate for example), with an acid (sulfuric acid for example); the precipitation mode of the silica can be arbitrary here: in particular, addition of acid on a silicate base stock, simultaneous total or partial addition of acid and silicate on a base stock of water or silicate solution .
- a silicate such as an alkali metal silicate (sodium silicate for example)
- acid sulfuric acid for example
- the precipitation mode of the silica can be arbitrary here: in particular, addition of acid on a silicate base stock, simultaneous total or partial addition of acid and silicate on a base stock of water or silicate solution .
- the precipitated silica in dispersed form which is used consists of:
- an aqueous suspension of precipitated silica said suspension preferably being obtained by disintegration (fluidification), then optionally grinding wet and / or stabilization with an additive, of a filter cake resulting from the precipitation reaction; it should be noted, even if this does not constitute the preferred variant of the invention, that said precipitated silica suspension used can be that obtained at the end of the precipitation reaction, before the filtration step.
- the silica is precipitated, the suspension obtained is filtered, a filtration cake is obtained which is washed if necessary, this cake can then be disintegrated.
- the precipitated silica preferably has a BET specific surface of at least 50 m 2 / g, in particular at least 90 m 2 / g, in particular between 100 and 400 m 2 / g, for example between 110 and 250 m 2 / g.
- the BET specific surface is determined according to the BRUNAUER - EMMET - TELLER method described in "The Journal of the American Chemical Society", Vol. 60, page 309, February 1938 and corresponding to standard NF T 45007 (November 1987).
- inorganic pigment In general, 2 to 30% is used, in particular 5 to 25%, for example 5 to 15%, by weight of inorganic pigment relative to the weight of silica (dry equivalent) + pigment.
- the precipitated silica in dispersed form advantageously consisting of a filtration cake resulting from the precipitation reaction, or a suspension of precipitated silica, preferably obtained by disintegration, then optionally stabilization of a filtration cake resulting from the precipitation reaction, can be very easily mixed with the inorganic pigment, preferably based on a metallic compound, without any grinding or controlled flocculation process.
- the metal compound is generally introduced in powder form, without prior dissolution.
- the consistency of the silica / pigment mixture can be adapted in particular by adding water in order to obtain a more fluid system, or by adding silica in powder form in order to obtain a drier paste.
- the silica / pigment mixture obtained is preferably subjected to calcination, optionally after prior drying (for example between 80 and 110 ° C).
- the calcination is generally carried out at a temperature between 400 and 1300 ° C, in particular between 600 and 1300 ° C, preferably between 800 and 1200 C.
- the calcination can thus be carried out at a temperature between 800 and 1000 ° C, or, even more preferably, at a higher temperature, in this case between 1000 and 1200 ° C., depending on the colorimetric parameters sought in the final ceramic material after firing.
- the duration of the calcination is preferably at least 30 minutes, in particular at least 45 minutes, for example between 45 and 80 minutes.
- the calcination is carried out at a temperature between 1000 and 1200 ° C, for at least 45 minutes, for example for 45 to 80 minutes.
- the calcination is most often followed by grinding (or crushing), in particular in order to obtain the desired particle size.
- a fine dye powder is thus obtained, for example having a BET specific surface of between 15 and 75 m 2 / g, in particular between 20 and 50 m 2 / g, in particular between 20 and 40 m 2 / g.
- the subject of the invention is also a dye (capable of being) obtained by calcination, then optional grinding, of a mixture of precipitated silica in dispersed form and of an inorganic pigment.
- a dye capable of being obtained by calcination, then optional grinding, of a mixture of precipitated silica in dispersed form and of an inorganic pigment.
- the dye according to the invention or resulting from the use of precipitated silica in dispersed form according to the invention is particularly suitable for the coloring of ceramic materials, for example in stoneware, in particular in porcelain stoneware (Porcellenato stoneware), by its very good color properties; it gives them, in particular in the case where the initial inorganic pigment used is based on an iron compound, in particular a high gloss and a high intensity (red / brown).
- the invention can also make it possible not to use auxiliary additives such as a silicone oil or a silane. In addition, it does not require the use of sol-gel type techniques such as controlled flocculation of silica.
- the dye, in powder form, can be mixed with the ceramic paste before shaping by pressing and (after possible drying) firing / sintering at high temperature (in particular between 1000 and 1300 ° C, for example between 1200 and 1250 ° C), in particular for 20 to 150 minutes, for example between 25 and 70 minutes or between 45 and 90 minutes, of total cycle (coloring in the mass).
- high temperature in particular between 1000 and 1300 ° C, for example between 1200 and 1250 ° C
- 20 to 150 minutes for example between 25 and 70 minutes or between 45 and 90 minutes, of total cycle (coloring in the mass).
- Ceramic materials for example formed from sandstone, in particular porcelain stoneware (Porcellenato stoneware), containing at least one dye as described above constitute one of the objects of the invention.
- Ceramic materials can in particular be tiles, tiles for example made of porcelain stoneware (Porcellenato stoneware), in particular red to brown in color when the initial inorganic pigment used is based on an iron compound.
- the dye according to the invention or resulting from the use of precipitated silica in dispersed form according to the invention is also suitable for the coloring of materials with a hydraulic or bituminous binder.
- These materials with a hydraulic or bituminous binder containing at least one such dye also constitute one of the objects of the invention.
