Abstract

The invention relates to high-stability LED-UV white ink-jet printing ink and a preparation method thereof. The ink comprises the following components in percentage by mass: 20.0 to 40.0% of a titanium dioxide-containing color paste, 8.0 to 20.0% of a photosensitive prepolymer resin, 20.0 to 43% of an active diluent, 5.0 to 10.0% of a photoinitiator, 0.5 to 1.0% of a leveling agent, 0.3 to 1.0% ofa polymerization inhibitor and 1.0 to 3.0% of an anti-settling agent. The preparation method comprises the following steps: mixing the photosensitive prepolymer resin with the active diluent, then adding the photoinitiator, the leveling agent, the polymerization inhibitor and the anti-settling agent in dark, and finally adding the titanium dioxide-containing color paste. The ink is high in stability, good in fluency, good in covering power and high in curing speed.

Description

technical field [0001] The invention belongs to the field of UV photocurable ink and its preparation, in particular to a high-stability LED-UV white inkjet printing ink and its preparation method. Background technique [0002] Inkjet printing inks are mainly divided into UV light-curable inks, water-based inks, and solvent-based inks. Water-based inks are difficult to evaporate and dry for non-absorbent substrates, and the printing accuracy is not ideal due to infiltration, while solvent-based inks, because the formula contains more than 80% of organic solvents, have greater pollution to the environment, thus limiting the two. development of inks. Due to the advantages of energy saving, high efficiency, strong adaptability to substrates, and ultra-low VOC emissions, UV light-curable inks, especially as the country's environmental protection requirements become more and more stringent, green and environmentally friendly UV inks have been rapidly developed. develop.
