Problems solved by technology

[0004] At present, most of the color pastes on the domestic market are solvent-based or water-based color pastes. If water-based or solvent-based color pastes are used to prepare UV-curable inkjet inkjet inks, the water or solvent contained therein will inevitably affect the light-curing speed, and at the same time Produces polluting organic gases that negatively affect the health of the operator

Embodiment 1

[0025] Preparation of Wetting and Dispersing Stabilizers

[0026] First, 20.62 g of sodium styrene sulfonate was dissolved in 600 g of reaction solvent N-methylpyrrolidone, stirred to fully dissolve it, and then 28.25 g of oleic acid and 3-(methacryloyloxy)propyl Add 28.80 g of trimethoxysilane, then add 1.18 g of initiator dibenzoyl peroxide, stir until fully dissolved, and react at 90° C. for 3 hours at a stirring speed of 200 r / min to obtain a light yellow polymer solution. After centrifugation, the polymer solution was washed with N-methylpyrrolidone, centrifuged again, repeated 3 times, and finally centrifuged to obtain sodium styrene sulfonate, oleic acid and 3-(methacryloyloxy)propyltrimethoxysilane The terpolymer, that is, wetting and dispersion stabilizer.

[0027] Through infrared analysis, the structure of the above product is characterized, and the infrared spectrum is as follows figure 1 shown. As can be seen from the figure, 1602.6cm -1 、1494.6cm -1 、1456.0c...

Embodiment 2

[0030] Preparation of Nanoscale UV Curable Inkjet Red Color Paste

[0031] First the wetting dispersion stabilizer 4.2Kg that tripropylene glycol diacrylate 50Kg, aliphatic polyurethane acrylate UA VP LS2265 25.5Kg and embodiment 1 prepare, defoamer BYK-0880.5Kg are placed in mixing tank and evenly mixed 10min, then Slowly and uniformly add 20Kg of quinacridone red C.I.PR 122 pigment to the above mixed liquid components under the stirring state of 2000r / min. The mixture is ground with a sand mill again until the maximum particle size of the pigment is less than 800nm, and then the grinding is stopped to obtain a nano-scale UV-curable inkjet inkjet red color paste, and its particle size distribution is as follows: figure 2 shown.

[0032] It can be seen from the particle size distribution diagram that the maximum particle size of the nanoscale UV-curable digital inkjet printing ink is less than 500 nanometers.

Embodiment 3

[0034] Preparation of Nano-scale Ultraviolet Curable Inkjet Yellow Color Paste

[0035] First place glycidyl methacrylate 59Kg, aliphatic polyester acrylate CN227610Kg, CN22856Kg and embodiment 1 prepared wetting dispersion stabilizer 6.3Kg, defoamer BYK-0880.7Kg in the mixing tank and uniformly mix for 10min, then Slowly and uniformly add permanent yellow C.I.PY 15118Kg pigment to the above-mentioned mixed liquid components under the stirring state of 2000r / min. Grinding with a sand mill until the maximum particle size of the pigment is less than 800nm ​​stops grinding to obtain a nano-scale UV-curable inkjet inkjet yellow color paste.

Abstract

The invention discloses a nanoscale ultraviolet curing ink jet drawing color paste which contains an active diluent, an oligomer, a wetting dispersion stabilizer, a defoaming agent and a pigment. The nanoscale color paste does not contain water or organic solvent; the active diluent and the oligomer which are used as dilution raw materials can participate in photopolymerization; and the wetting dispersion stabilizer can be used for obviously increase the integral stability of the color paste. The nanoscale color paste can be used for preparing ultraviolet curing or electron beam curing ink jet drawing ink and can also be used in other energy curing fields.

Description

technical field [0001] The invention relates to the technical field of pigment colorants, in particular to a nano-scale ultraviolet light-curable inkjet colorant paste and a preparation method thereof. Background technique [0002] Photocuring refers to the curing process of monomer, oligomer or polymer matrix under light induction. This technology has a wide range of applications in modern microelectronics technology, such as photocurable ink, liquid crystal panel packaging, photosensitive printing plate, Filters and photoresists, etc. Under the irradiation of ultraviolet / visible light, X-ray or laser at a certain wavelength, the photoinitiator generates active groups, which excites the unsaturated groups in the polymerizable monomer to undergo polymerization reaction, thereby causing the curing of the material. [0003] With the advancement and improvement of digital printing technology and UV curing technology, the UV curing digital printing technology produced by the co...
