    [0001]
    [0002] The present invention is part of the field of inkjet inks using drop -on-demand technology (DoD) that provide chromatic or ceramic effects on ceramic supports once subjected to a cooking cycle at temperatures between 850 ° C and 1280 ° C.
    [0003]
    [0004] STATE OF THE ART
    [0005] The decoration and enamelling of ceramic products by inkjet is widely implemented at an industrial level. In this sense there are equipment based on the technology of injection heads called drop on demand (DoD). DoD printing is characterized by using print heads based on the use of piezoelectric with firing frequencies, which depending on the manufacturer of the head, range between 0.05 - 300 KHz, being the best known manufacturers of this type of heads companies Dimatix (Fujifilm), Xaar, Seiko, KM or Ricoh among others, to generate ink droplets on a picometric scale that come out through an orifice with a diameter not exceeding 50 micrometers. Droplets are expelled only when they are required, so It is called "under demand." A fundamental characteristic that must be fulfilled by the inks for application using DoD technology is a D50 particle size at the nanometric level, in order to prevent the particles from blocking the exit holes of the injection head. important is the stability of the ink in the printing equipment to get a correct impression.This stability includes value s constant of certain parameters such as viscosity, surface tension and drying speed. It is also important to note the absence of sedimentation of the nanometric solid particles since it also causes the blocking of the ink outlet orifices in the injection heads and, therefore, the absence of printing.
    [0006]
    [0007] In the state of the art there are compositions of inks and ceramic enamels based on this type of DoD digital printing technology. Thus the patent ES2257957 protects an ink free of water composed of inorganic materials and which, once deposited on the ceramic support and subjected to a heat treatment, develops a coloration. In addition, the aforementioned patent ES2257957 describes the use of dispersing agents and agents soluble stabilizers in the non-aqueous medium of the ink. Its main function is to stabilize the solid particles by keeping them suspended in the non-aqueous medium and, therefore, preventing their agglomeration and sedimentation. However, these dispersing and stabilizing agents are characterized by not being effective when it is required to stabilize particles (pigments, ceramic frits or ceramic raw materials) in a medium containing water since, given their chemical nature, they are not solubilized in a medium containing Water. The reason is that its mechanism of stabilization of solid particles is based on a chemical structure capable of interacting sterically with the solid particle in the non-aqueous medium.
    [0008]
    [0009] For its part, the patent ES2468553 describes a digital enamel composition for ceramic tiles comprising a liquid part free of water, inorganic particles of ceramic frits and / or ceramic raw materials and at least one dispersant. Again the dispersants and humectants described in the patent ES2468553 are characterized for being effective only in the steric stabilization of the particles in non-aqueous media and therefore, they are not viable in liquid media with water.
    [0010]
    [0011] Also note the patent application P201631554 that describes a water-based ceramic enamel for application by digital technology other than Drop-on-Demand on ceramic substrates. The main feature of this digital enamel is that, since it is not intended for application using DoD technology, it comprises a high content of ceramic frit and / or ceramic raw materials (between 40% and 55% by weight) and a large size of particle, comprised between 40 micrometers and 65 micrometers. In order to stabilize the high solids content and its high particle size, the patent application is characterized by the specific use of sodium chloride and / or sodium polyacrylate and / or potassium polyacrylate and / or an ethoxylated polyurethane. However, these compounds are only effective for formulations which, although they are water based, contain high solids contents with a D100 particle size greater than 40 microns.

    [0013] EXPLANATION OF THE INVENTION
    [0014]
    [0015] Throughout the invention and the claims the word "comprises" and its variants do not intend to exclude other technical characteristics, additives, components or steps.In addition, the word "comprises" includes the case "consists of." For experts in the matter, other Objects, advantages and characteristics of the invention will be derived partly from the description and partly from the practice of the invention.
    [0016]
    [0017] The term "ceramic support" as used in the present invention refers to any flat or relief surface consisting of a mixture of clays and / or ceramic materials (ceramic frits, silicates, feldspars, oxides, etc.) formed by the usual techniques in the ceramic sector such as press, lamination or extrusion, among others, which can be enameled or unglazed as well as raw or subjected to a cooking cycle Examples of ceramic support, including but not limited to, includes ceramic tiles , tiles, bricks, crockery and toilet.
    [0018]
    [0019] The present invention is a water-based ink, whose liquid medium contains water at a minimum percentage of 20% by weight of the liquid phase, for ink injection using DoD technology for enameling or decorating ceramic supports. Unlike the state of the art, which bases the stability of the nanoparticles for DoD technology in the use of non-aqueous solvents, without water content, and dispersants that stabilize through steric interaction, that is, using the morphology of the dispersant molecule to hinder the agglomeration of nanoparticles; the present invention manages to stabilize nanometric particles in aqueous media, among other aspects, through the use of specific additives, among which the use of dispersants stands out. These dispersants present in the water-based inks object of the invention succeed in stabilizing the nanoparticles by combining both electrostatic-type nanoparticulate dispersion interactions, that is, neutralization of charges between the dispersant molecule and the particle; as of steric type interactions. Only by combining both interactions is it possible to obtain water-based inks for stable DoD technology and with correct behavior during printing.
    [0020]
    [0021] In turn, the ink of the present invention is characterized in that, once deposited on the ceramic support, it provides chromatic or ceramic effects after a cooking cycle at temperatures between 850 ° C and 1280 ° C.
    [0022]
    [0023] The fact that the ink object of the invention comprises a water-based liquid medium, with a water content at a minimum percentage of 20% of the weight of the liquid phase, represents an environmental improvement since during the heat treatment the emissions of the water are reduced. CO2 and other chemical compounds with respect to the existing inks in the state of the art.
    [0024]
    [0025] The present invention provides a water based ink applicable by DoD technology comprising:
    [0026] to. Water with a conductivity (k) lower than 50 ^ .S / cm and in a percentage by weight of the ink comprised between 10% and 45%.
    [0027] b. At least one solvent in a percentage by weight of the ink comprised between 10% and 55%. This solvent or mixture of solvents is characterized in that it is completely soluble in water in all proportions.
    [0028] c. At least one type of solid particle in a percentage by weight of the ink comprised between 15% and 50%.
    [0029] d. At least one dispersant completely soluble in the water-based liquid medium of the ink and in a percentage by weight of the ink comprised between 1% and 25%.
    [0030] and. At least one humectant in a percentage by weight of the ink comprised between 0.05% and 1%.
    [0031] F. At least one defoamer in a percentage by weight of the ink comprised between 0.01% and 1%.
    [0032] g. At least one preservative in a percentage by weight of the ink comprised between 0.05% and 1%.
    [0033]
    [0034] In the formulation of inks for DoD inkjet technology it is fundamental to define a series of properties that ensure their correct behavior. In this regard, the value of the viscosity as a function of the shear rate or derivative of the transverse deformation with respect to time, both when the water-based ink is practically at rest (shear rate at 10 s-1) and when It finds movement in the printing equipment circuit (shear rate between 100 s-1 and 1000 s-1). The measurement of the shear rate has been made with an Anton Paar cone-plate type rheometer model MCR102. The measurement procedure consists of placing the water-based ink on a horizontally heated plate. Subsequently the cone lowers and begins to rotate by measuring the torque. From the torque value, the viscosity value is calculated at a certain temperature and shear rate. In this sense, the water-based ink object of the present invention is characterized by having the following viscosity values at 40 ° C as a function of the shear rate:
    [0035] • Between 8 cP and 35 cP at 10 s-1 shear rate.
    [0036] • Between 8 cP and 35 cP at 100 s-1 shear rate.
    [0037] • Between 6 cP and 30 cP at 1000 s-1 shear rate.
    [0038]
    [0039] In the field of inkjet inks, it is usual to use the cegesimal centipoise unit (cP) where 1 cP equals 0.001 Pas in the International System of Units.
    [0040]
    [0041] The solvents used in the ink object of the invention are characterized in that they are completely soluble in water in any proportion. These solvents are selected from the group comprising monoethylene glycol, monopropylene glycol, ethylene glycol propyl ether, ethylene glycol n-butyl ether, diethylene glycol, diethylene glycol methyl ether, diethylene glycol ethyl ether, diethylene glycol n-butyl ether, triethylene glycol, triethylene glycol methyl ether, triethylene glycol ethyl ether, triethylene glycol. -butyl ether, tripropylene glycol methyl ether, polyethylene glycol of molecular weight equal to or less than 400 g / mol, 1,2,3-propanetriol and 1,5-pentanediol.
    [0042]
    [0043] According to the present invention, the solid particle present in the water-based ink forms the solid phase of the ink and comprises, at least, either a ceramic pigment, or a ceramic frit or a ceramic raw material or a mixture of the previous
    [0044]
    [0045] In a preferred embodiment of the present invention the water-based ink comprises:

    [0047] b. At least one solvent in a percentage by weight of the ink comprised between 10% and 55%. This solvent or mixture of solvents is characterized in that it is completely soluble in water in all proportions.

    [0051] g. At least one preservative in a percentage by weight of the ink comprised between 0.05% and 1%.
    [0052]
    [0053] The term "ceramic pigment" as used in the present invention refers to any synthetic or natural inorganic compound that is characterized by remaining unchanged and providing a coloration to the ceramic support once deposited thereon and carried out the corresponding heat treatment. Examples of ceramic pigments, including but not limited to, are various crystalline structures such as zirconium silicate, olivine, sphene, spinels, perovskites, hematites, etc., as they are or doped with cations such as praseodimino, vanadium, cobalt, iron , chromium, cerium, etc., iron oxide, titanium oxide, chromium oxide and cobalt oxide.
    [0054]
    [0055] In another preferred embodiment of the present invention the water-based ink comprises the use of at least one ceramic frit in the composition of the water-based ink. The particle size of the frit or ceramic frits is less than 650 nanometers expressed in D50 and has a coefficient of thermal expansion between 40 x 10-7 ° C-1 and 80 x 10-7 ° C-1 measured at 300 ° C. Ceramic frits can be made, but not limited to, from natural or synthetic products such as oxides, silicates, carbonates, aluminosilicates, borates, etc, calcium, silicon, zinc, bismuth, boron, potassium, zirconium, cerium, etc or their mixtures.
    [0056]
    [0057] Additionally, in another embodiment, the water-based ink may contain ceramic raw materials with a particle size D50 less than 500 nanometers. The term "ceramic raw material" as used in the present invention refers to any chemical compound other than ceramic frits and ceramic pigments that is incorporated directly into the composition of the water-based ink object of the invention. for example but not limited to, includes sodium feldspar, potassium feldspar, lithium feldspar, alumina, kaolinitic clays, illitic clays, zirconium silicate, zinc oxide, tungsten oxide, dolomite, kaolin, quartz, barium oxide, mullite, bentonite, wollastonite, tin oxide, nepheline, bismuth oxide, boron oxide, colemanite, calcium carbonate, aluminum phosphate, manganese oxide, spodumene, talcum, magnesium oxide, cristobalite, rutile and anatase.
    [0058] Also, in another preferred embodiment of the present invention the water-based ink comprises:
    [0059] to. Water with a conductivity lower than 50 ^ .S / cm and in a percentage by weight of the ink comprised between 10% and 45%.
    [0060] b. At least one solvent in a percentage by weight of the ink comprised between 10% and 55%. This solvent or mixture of solvents is characterized in that it is completely soluble in water in all proportions.
    [0061] c. At least one ceramic frit and at least one ceramic raw material in a percentage by weight of the ink comprised between 15% and 50%. The ceramic frit has a particle size D50 less than 650 nanometers and the ceramic raw material a particle size D50 less than 500 nanometers.
    [0062] d. At least one dispersant completely soluble in the water-based liquid medium of the ink and in a percentage by weight of the ink comprised between 1% and 25%.
    [0063] and. At least one humectant in a percentage by weight of the ink comprised between 0.05% and 1%.
    [0064] F. At least one defoamer in a percentage by weight of the ink comprised between 0.01% and 1%.
    [0065] g. At least one preservative in a percentage by weight of the ink comprised between 0.05% and 1%.
    [0066]
    [0067] Since the solid particles present in the water-based inks subject of the invention are characterized by a low particle size and a solids content of up to 50% by weight of the ink, one of the most important aspects to achieve a correct stability is the selection of the dispersant or dispersants present in the formulation. In this sense, the water-based ink object of the invention has the advantage over the state of the art that the dispersant or mixture of dispersants is completely soluble in the liquid aqueous medium of the ink and has an optimum interaction with the particles that it is desired to stabilize. , avoiding its sedimentation. In this sense the dispersant completely soluble in the liquid part of the ink is selected from the group comprising polyacrylate salt, acrylate copolymer, high molecular weight acrylic copolymer, alkoxides, non-ionic modified fatty acid derivatives, carboxylic acid salt, phosphoric polyether and polycarboxylic acid salt.
    [0068] The present invention also comprises the use of at least one humectant which is capable of acting correctly in an aqueous medium and with the particle sizes and their own concentrations of the water-based ink object of the invention. In this sense the humectant is selected from the group comprising mixture of ethers with polyethylene-polypropylene glycol with monobenzyl ether and C8-C10 alcohols, polyether-polysiloxane copolymer and non-ionic surfactants.
    [0069]
    [0070] It should also be noted that the water-based ink object of the invention is introduced into a digital printing equipment and is continuously in motion in the printing circuit. As a result, foam and bubbles are generated. The presence of foam or bubbles is a big problem when printing with DoD technology since the injection head injects air instead of ink, which causes a defect in the final application. Therefore, the present invention also comprises at least one antifoam which is selected from the group comprising modified silicones, polydimethylsiloxanes, mineral oil derivatives and fatty derivatives.
    [0071]
    [0072] In contrast to the digital inks and enamels present in the state of the art, the high water content of the injected inks makes it necessary to incorporate preservatives that prevent the development of bacteria and other microorganisms that degrade the composition. Therefore, the water-based ink of the present invention comprises at least one preservative selected from the group comprising a mixture of 1,2-benzisothiazol-3-one and 1,2-benzisothiazol-3 (2H) -one, 2-methyl -2H-isothiazol-3-one, bronopol, sodium piritone and tetramethiol acetylene diurea.
    [0073]
    [0074] Another important property of the ink is the surface tension since it determines its behavior in the face plate (face-plate) of the injection head. In this sense, the water-based ink of the present invention has a surface tension value between 20 mN / m and 40 mN / m.
    [0075]
    [0076] Since the ink contains water it is especially important to adjust the evaporation of the ink when it is in the digital printing equipment DoD, since it would cause the ink to dry out in the ejection holes of the injection head and therefore, its obturation. For this, the water-based ink object of the invention is characterized by having an evaporation rate of less than 35% when heated at 50 ° C for 240 minutes. Evaporation rate is a term widely used in the formulation of inks of the ceramic sector to define the weight loss of a composition at a certain temperature and time. Specifically in the present invention, the evaporation rate has been determined by the thermogravimetry method using a Netzsch model STA409 thermogravimetry equipment. The equipment contains a base on which a container containing the sample to be measured is deposited. For this, the container is previously placed without sample and the thermobalance is tared to discard the mass of the container. Then a known mass (m0) of the sample to be measured is added to the container. The equipment automatically weighs the mass m0. The equipment is then heated to 50 ° C without the presence of the container with the sample. Once it has reached 50 ° C, the container is deposited with the sample and left at that temperature for 240 minutes. The team records the mass loss during that time (m1). Finally, the evaporation rate is calculated according to the equation:
