The invention discloses an ink for ceramic ink-jet printing and a method for preparing the same, wherein the ink comprises the following components by mass percent: 20-50% of ceramic pigment, 3-8% of resin, 2-10% of dispersant, 0.1-0.2% of flatting agent, 0.3-0.7% of defoamer, 0.08-0.12% of anti-settling agent and the balance of solvent; and the dispersant is a high-molecular-weight polyurethane type dispersant or a high-molecular-weight polyacrylate type dispersant. The ink for ceramic ink-jet printing provided by the invention is good in quality stability and thereby can be stored for a long time; the ink is excellent in ink-jet printing performance, low in ink viscosity and even in particle size distribution; the viscosity of the ink is between 10.0 and 40.0 mPa.s and is controllable; and the surface tension of the ink is 28-38 mN/m, while the average particle size is 200-300 nm and the maximum particle size is less than 800 nm. The method for preparing the ink for ceramic ink-jet printing provided by the invention is simple and efficient; and a one-step mill base grinding process and an ink performance regulation process are carried out, so that the production cost is greatly saved.

The present invention discloses a matte glaze ink for ceramic jet printing and preparation method thereof, wherein the ink comprises, based on the mass percentage, 30-50% of matte glaze, 3-8% of resin, 2-10% of dispersant, 0.1-0.2% of leveling agent, 0.3-0.6% of defoaming agent, 0.08-0.12% of anti-settling agent and the balance for the solvent, wherein the matte glaze includes raw materials of the following components of SiO2, Al2O3, K2O, Na2O, CaO, MgO, ZnO and BaO. Matte glaze ink prepared by the invention has low viscosity, uniform distribution of particle diameter with maximum particle diameter of less than 1Mum and good printing performance. Fired glaze owns gentle matte finish.

The invention discloses antibacterial ceramic inkjet ink with a marble crack effect and a method for preparing the antibacterial ceramic inkjet ink. The method includes steps of A, mixing and stirring solvents, hyper-dispersants, regulators, defoaming agents and anti-diffusion agents with one another to obtain mixed solution, adding 0.1-5% antibacterial compounds into the mixed solution and uniformly stirring the antibacterial compounds and the mixed solution; B, adding permeating powder and photochromic compounds into the mixed solution, grinding the permeating powder, the photochromic compounds and the mixed solution, then adding solvents and anion compounds into the mixed solution and grinding the solvents, the anion compounds and the mixed solution to obtain semi-finished ink products; C, filtering the semi-finished ink products to obtain finished ink products. The antibacterial ceramic inkjet ink and the method have the advantages that as compared with existing ceramic ink, the antibacterial ceramic inkjet ink manufactured by the aid of the method contains scientific ingredients, is stable in performance and has grains, colors and textures of natural marble, decoration effects of ceramic tiles further can be improved, and the antibacterial ceramic inkjet ink further can be widely applied to the fields of ceramic chips, antique bricks and the like; the photochromic compounds, the anion compounds and antibacterial composite materials are reasonably matched with one another, accordingly, the antibacterial ceramic inkjet ink is excellent in antibacterial performance, air purification and photochromic characteristic, and the application range of the antibacterial ceramic inkjet ink further can be broadened.

The invention discloses a white stain-bleeding printing ink for ceramic ink-jet printing and a preparation method thereof. The printing ink is composed of following components in percentage by weight:0.05 to 0.2 wt.% of a leveling agent, 20 to 25 wt.% of chromophoric organic metal salts (by the weight of metal ions), and the balance being a solvent; wherein the chromophoric organic metal salts are mixed metal salts of organic cerium, organic zirconium, and organic aluminum. The printing ink has a white decorative effect, the species of ceramic stain-bleeding printing inks are enriched, and the decorative effect of ink-jet bleeding-stained bricks is further enhanced.

The invention discloses antibacterial ceramic ink with depression effects for ceramic inkjet and a preparation method thereof. The preparation method comprises the following steps: a step A, preparation of glaze with depression effects; a step B, glaze with depression effects, a dispersant, a surface additive, an antifoaming agent, a binder, and the balance being a solvent are weighed according to a proportion, and an ink semi-finished product is grinded; a step C, an ink finished product is filtered. Compared with prior ceramic ink with depression effects, the ceramic and pigment ink are matched for usage, in order to fully and visually present accidented and vivid texture of the tiles with good stereo perception, further the decorative effects of the tiles are improved, patterns with extraordinary splendor are created, and the ink can be widely applied to ceramics and antique bricks and other fields. At the same time, a negative ion compound, a deodorant and an antibacterial composite material are reasonably matched, the three materials are synergetic, so that the ceramic ink has excellent antibacterial, antifouling and air purifying characteristics, further application ranges of the ceramic ink with depression effects are widened.

The invention discloses a composition for packaging a photoelectronic device. The composition comprises the following components in percentage by mass: 49-91% of a multi-component acrylate monomer; 6%-50% of a monofunctional group acrylate monomer; and 0.5%-5% of a photoinitiator. A packaging adhesive formed by using the silicon-containing acrylate component has the advantages that on one hand, the stress dispersion effect can be achieved, the internal stress is reduced, and the mechanical property of the organic packaging composition is improved; and on the other hand, the thermal performance and hydrophobic performance of the organic packaging composition can be effectively improved, and the service life of a device can be effectively prolonged when the organic packaging composition is used for film packaging of an optoelectronic device. In addition, due to the introduced aryl or heteroaryl and derivative units thereof, conjugation in molecules is enhanced, and the absorption effect of the packaging layer on ultraviolet rays is improved.
