Description
Technical Field
The invention relates to the technical field of digital jet printing ink, in particular to water-based yellow polymer ink and a preparation method thereof.
Background
Digital inkjet printing is a technique based on sending digitized pattern data to an inkjet printer and ejecting ink drops to print a pattern directly on a substrate. Compared with the traditional graphic printing technology, the digital ink-jet printing technology can easily create or customize a printed image, and a printing object does not need to be contacted with a printing head, so that various materials and objects with complex shapes can be used as the printing object. In addition, this printing technique can achieve higher ink efficiency because the ink is ejected only to the desired location using a digital inkjet printing method based on drop-on-demand.
Because of these advantages, ceramic inkjet printing has been the technology of choice in the tile decorating industry for the past decade. However, despite success, the industry has recently been under pressure for environmental problems such as global warming and air pollution. Since most of inks used in digital inkjet printing are based on organic solvents and contain Volatile Organic Compounds (VOCs) to ensure dispersion stability and printability thereof, such inks have the following disadvantages: 1) Affecting human health may lead to occupational hazards for operators, and prolonged or repeated exposure to high levels of VOCs may have serious health effects on the central nervous system, liver or kidneys; 2) Air pollution and environmental impact, VOCs released into the atmosphere can react with other pollutants and sunlight to form ozone, which adversely affects air quality and human health. When they are released into the soil or water, these resources may be contaminated, posing a threat to the plant, animal and aquatic ecosystem. In addition, VOCs emissions can also lead to the formation of greenhouse gases, exacerbating climate change.
It is therefore necessary to develop environmentally friendly and functional ceramic inks to replace organic solvent-based ink jet printing inks containing VOCs.
In view of this, the present invention has been made.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below. The specific conditions are not noted in the examples and are carried out according to conventional conditions or conditions recommended by the manufacturer. The reagents or apparatus used were conventional products commercially available without the manufacturer's attention.
The invention embodiment is a water-based yellow polymer ink, which is prepared from the following raw materials of yellow ceramic pigment, water-soluble polyacrylic acid polymer, thickener, surface tension mixing agent and water, wherein each cubic meter of the water-based yellow polymer ink contains 0.2-1.0 mg of the water-soluble polyacrylic acid polymer, and each 100 parts of the water-based yellow polymer ink contains 13-16% of the yellow ceramic pigment by volume fraction; the aqueous yellow polymer ink contains 0.01-15% by mass of a thickener per 100 parts of the aqueous yellow polymer ink and 0.01-0.1% by mass of a surface tension admixture per 100 parts of the aqueous yellow polymer ink.
Wherein the thickener is selected from polyol polymers, preferably polyethylene glycol; polyol polymers such as polyethylene glycol are commercially available materials, and are commercially available from, for example, the biosciences of Aibisin (Shanghai).
The surface tension mixture is selected from polysilanes. Polysilanes are also commercially available materials available today, for example from Shanghai Seiyaku Biotechnology Inc.
Thus, the aqueous yellow polymer ink contains 0.2-1.0 milligrams of water-soluble polyacrylic acid polymer per cubic meter, and 13-16% volume fraction of yellow ceramic pigment per 100 parts of the aqueous yellow polymer ink; 0.01-15% by mass of polyethylene glycol per 100 parts of the aqueous yellow polymer ink and 0.01-0.1% by mass of polysilane per 100 parts of the aqueous yellow polymer ink.
For example, the water-soluble polyacrylic acid polymer in the aqueous yellow polymer ink may contain 0.2 mg, 0.3 mg, 0.4 mg, 0.5mg, 0.6 mg, 0.7 mg, 0.8 mg, 0.9 mg, 1.0 mg, etc. of any value or any range of values between any two values between 0.2 and 1.0 mg per cubic meter.
The volume fraction of the yellow ceramic pigment is any value or any range of values formed by any two values between 13% and 16%, such as 13%, 14%, 15% and 16%.
The mass fraction of polyethylene glycol is any value or range of values formed by any two values between 0.01 and 15% such as 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, 0.5%, 1%, 5%, 10% and 15%.
The mass fraction of polysilane is any value or range of values formed by any two values between 0.01% and 0.1%, such as 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.07%, 0.08%, 0.09%, 0.1%, etc.
Wherein, the crystal structure of the yellow ceramic pigment adopted in the embodiment of the invention is ZrSiO doped with Pr 4 。ZrSiO 4 SiO with edge sharing 4 Tetrahedra and ZrO 8 The main building block of a triangular dodecahedron, which contains empty octahedral voids. The yellow ceramic pigment may be self-made or commercially available, for example, from Shandong Nernst Biotechnology Inc.
The embodiment of the invention also provides a preparation process of the yellow ceramic pigment, in particular ZrSiO 4 The synthesis process is as follows:
SiO 2 +4NaF→SiF 4 (g)+2Na 2 O
SiF 4 →Si 4+ +4e - +2F 2
Si 4+ +4e - +ZrO 2 +O 2 →ZrSiO 4
specifically: the base material, mineralizer, alumina balls and solvent (e.g., ethanol) are wet-mixed together for 3 hours to form a mixed powder, and then the mixed powder is dried at 75-85 deg.c, followed by calcination at 1000-1200 deg.c for 1-2 hours in an oxidizing environment (oxygen-containing atmosphere). Then, the obtained yellow ceramic pigment is micronized by using a bead mill, the particle size of the powder obtained after micronization is less than one fiftieth of the diameter of a nozzle for inkjet printing, and the average particle size is generally less than 300nm so as to prevent the nozzle of an inkjet printing head from being blocked.
Wherein, the mineralizer is selected from NaF, and the dosage of the mineralizer is 2-4% of the dosage of the base material.
The silicon dioxide is used in an amount of 30-40% by mass, the zirconium dioxide is used in an amount of 55-65% by mass and the praseodymium oxide is used in an amount of 2-7% by mass. The total amount of silica, zirconia and praseodymia was 100%.
The solid content of the aqueous acrylic polymer is 10-30%.
The water-based acrylic acid polymer is a polymer taking polyacrylic acid as a main chain and polyethylene glycol methyl methacrylate as a side chain. Specifically, the modified acrylic acid is synthesized from polyacrylic acid, ammonium persulfate, hydroquinone monomethyl ether and polyethylene glycol methyl methacrylate.
The present examples select polyacrylic acid as the backbone to ensure electrostatic repulsion and polyethylene glycol methyl methacrylate as the side chain to provide steric hindrance. When the effects of electrostatic repulsion and steric hindrance are combined, high dispersion stability of pigment particles in the aqueous ceramic ink can be achieved.
Further, the aqueous acrylic polymer may be self-made or purchased as a finished product, such as from Beijing Cheng Weihua chemical Co.
This example provides the following illustrative preparation steps: polyacrylic acid and polyethylene glycol methyl methacrylate (molar ratio of both = 1.5-2.0) were mixed with hydroquinone monomethyl ether (0.5-1.0% of total monomer weight) in deionized water. After complete dissolution, the polyacrylic acid solution and ammonium persulfate (0.5-1.0% by weight of the total monomer weight) were added dropwise to deionized water in the reactor to form a mixture. The reactor was equipped with a reflux condenser, a feed inlet and an air inlet pipe. The mixture was stirred and heated at 75-95 ℃ for 4-6 hours. After that, the reaction solution was cooled to room temperature, and the pH was adjusted to 5-6 with NaOH (40-60% by weight aqueous solution). Finally, a brown transparent polymeric surfactant is obtained.
It should be noted that the preparation methods of the yellow ceramic pigment and the aqueous polyacrylic acid polymer provided in the embodiments of the present invention are merely examples of the embodiments of the present invention.

Test case
Viscosity depends on interactions between particles, in particular, weak interactions result in low viscosity, while strong interactions result in high viscosity, and viscosity measurements also reflect the dispersibility of the ink, i.e., lower viscosity, more dispersed ink, and uniform and stable dispersion.
Therefore, sodium Dodecyl Sulfate (SDS) (purchased from shenzhen vibro biotechnology limited), polyacrylic acid (purchased from beijing Cheng Weihua chemical engineering limited) and the aqueous polyacrylic acid polymer provided in example 1 of the present invention were used as a surfactant, and inks were prepared at different concentration gradients and the viscosity of the inks was measured, respectively. The yellow ceramic powder, polyethylene glycol and polysilane content of the ink were the same as in example 1.
The results are shown in FIG. 1. As can be seen from fig. 1, the viscosity of the ink can be significantly reduced by using the aqueous polypropylene polymer in the embodiment of the present invention, and the aqueous polypropylene polymer can be sufficiently adsorbed to the surface of the ceramic particles, thereby effectively blocking the interaction between the ceramic particles. In particular when the content of the aqueous polypropylene polymer is 0.5mg/m 2 The viscosity of the ink was 1.15 mPas, at which point the viscosity was optimal.
Detection example 2
The water-soluble polyacrylic acid polymer in example 1 was replaced with polyacrylic acid (available from Sank materials technologies Co., ltd. Of Hubei), and the water-soluble polyacrylic acid polymer was not used, and the zeta potential, hydrodynamic radius and sedimentation velocity of 3 inks were then tested.
The results are shown in fig. 2 and 3. As can be seen from FIG. 2, the zeta potential of the aqueous polymer ink was-18.7 mV without the surfactant, and the zeta potential after the addition of the polyacrylic acid and the aqueous polyacrylic acid polymer was-39.4 mV and-42.1 mV, thus indicating an improvement in the dispersion stability of the ink. In general, zeta potentials between 0 and-30 mV are considered to represent low dispersion stability, while exceeding-30 mV represents good dispersion stability. Furthermore, the hydrodynamic radius of the aqueous polymer ink was 265nm without surfactant, and 315nm and 365nm, respectively, measured under polyacrylic acid and aqueous polyacrylic acid polymers.
As can be seen from FIG. 3, the sedimentation rates of the samples containing no surfactant and polyacrylic acid were 0.78mm/h and 0.67mm/h, respectively, whereas the sedimentation rate of the ink sample using the aqueous polyacrylic acid polymer as the surfactant was 0.29mm/h, which was 56.7% slower than the ink sample containing polyacrylic acid. Further, the dispersion stability of the aqueous yellow polymer ink provided by the embodiment of the invention is obviously improved.
Detection example 3
The yellow ceramic pigment of example 1 was changed to pigment yellow 81 yellow pigment (available from the company of pharmaceutical chemicals, inc. of the same flying, hubei) and tested for ink jet morphology and printability.
Results referring to fig. 4, fig. 4 shows a comparison of the spray pattern and printability of different yellow pigment inks, where a is the yellow ceramic pigment employed in the examples of the present invention and b is pigment yellow 81. From fig. 4, it can be seen that pigment yellow 81 observed longer tail and satellite ink droplets, and also found dripping after the initial ink droplets were ejected, the print dot area was not uniform in size, and the print quality was affected.
Detection example 4
X-ray and SEM electron scan test of the yellow ceramic pigment prepared in example 1, see FIG. 5, wherein table a in FIG. 5Showing the X-ray diffraction (XRD) pattern of the yellow ceramic pigment; b represents an electron field emission scanning electron microscope (FE-SEM) image. As can be seen from FIG. 5, the main phase of the yellow ceramic pigment of the present invention is ZrSiO 4 . As is clear from FIG. 5, the yellow ceramic pigment has an irregular particle shape with rough edges, a particle diameter of about 50 to 900nm, a D90 particle diameter of 647nm, and an average particle diameter of 289nm. This shape is due to the high mechanical energy of the ceramic particles being decomposed during micronization.
