Embodiment 1

[0026] Take 50 parts of cyan pigment, 15 parts of aldehyde and ketone resin, 20 parts of monomer, and 5 parts of dispersant with a balance, pour the above-mentioned components into the stirring device, stir with a mechanical mixer for 20 minutes to make them evenly mixed, and then pour them into sand In the grinding chamber of the mill, use a sand mill to grind and disperse for 45 minutes, and test its particle size. If the particle size is less than or equal to 150nm, stop grinding to obtain the base ink; mix 30 parts of base ink, 20 parts of agent, 30 parts of diluted monomer, and stirred with a mechanical mixer for 60 minutes to make it evenly mixed, and tested the indicators and performance of the ink. After passing the test, it was filtered and packaged to obtain the inorganic pigment UV inkjet ink.

Embodiment 2

[0028] Take 60 parts of inorganic pigments, 10 parts of aldehyde and ketone resins, 22 parts of monomers, and 8 parts of dispersants with a balance, pour the above components into the stirring device, stir with a mechanical mixer for 40 minutes to make them evenly mixed, and then pour them into sand In the grinding chamber of the mill, use a sand mill to grind and disperse for 30 minutes, and test its particle size. If the particle size is less than or equal to 150nm, stop grinding to obtain the base ink. If the particle size is greater than 150nm, continue grinding until the particle size is less than or equal to 150nm; 10 parts of base ink, 10 parts of acrylic resin, 12 parts of photoinitiator, 5 parts of auxiliary agent and 48 parts of monomer are mixed, stirred with a mechanical mixer for 40 minutes to make it evenly mixed, and the indicators and performance of the ink are tested, filtered and packaged after passing the test. An inorganic pigment UV inkjet ink is obtained. ...

Embodiment 3

[0030] Take 70 parts of inorganic pigments, 10 parts of aldehyde and ketone resins, 10 parts of monomers, and 10 parts of dispersants with a balance, pour the above components into the stirring device, stir with a mechanical mixer for 50 minutes to make them evenly mixed, and then pour them into sand In the grinding chamber of the mill, use a sand mill to grind and disperse for 30 minutes, and test its particle size. If the particle size is less than or equal to 150nm, stop grinding to obtain the base ink. If the particle size is greater than 150nm, continue grinding until the particle size is less than or equal to 150nm; Parts of base ink, 10 parts of acrylic resin, 12 parts of photoinitiator, 5 parts of auxiliary agent, and 48 parts of monomer. Stir with a mechanical stirrer for 40 minutes to make it evenly mixed, test the various indexes and performances of the ink, filter and pack after passing the test, and obtain the inorganic pigment UV inkjet ink.

Abstract

The invention relates to inorganic pigment UV ink-jet ink suitable for an industrial head and a preparation method thereof. The ink comprises the following components in parts by mass: 15-30 parts ofbase ink, 10-20 parts of UV resin, 6-15 parts of a photoinitiator and 30-60 parts of a diluting monomer. The base ink comprises an inorganic pigment, a grinding resin, a UV monomer and a dispersing agent, and the mass ratio of the inorganic pigment to the grinding resin to the UV monomer to the dispersing agent is (50-70): (5-15): (10-30): (3-10). The UV ink-jet ink is good in printing quality, good in weather resistance and simple in preparation method.

Description

technical field [0001] The invention relates to the field of inorganic pigment inkjet inks, in particular to a weather-resistant inorganic pigment UV inkjet ink especially suitable for outdoor construction and industrial heads and a preparation method thereof. Background technique [0002] At present, most of the inks used in construction are solvent-based inks, such as inkjet ceramic inks. Since solvent-based inks contain volatile organic solvents, ceramic inks must be sintered at a high temperature of 1000 degrees in the subsequent process before they can be cured. High energy consumption and solvent volatilization It causes environmental pollution and has adverse effects on the health of ink production personnel and printing machine operators. [0003] UV inkjet ink is a solvent-free ink, which completely eliminates the toxic and harmful substances in solvent inks, and has no VOC emissions during use, which reduces environmental pollution, improves the working environment...
