Embodiment 1

[0023] First, according to the weight ratio, put 25 parts of titanium dioxide pigment in a sand mill at room temperature to disperse and grind until the particle size is below 5 μm; mix the ground titanium dioxide with 50 parts of polyester acrylate EBECRYL 446 and 5 parts of 1,6-hexanediol diacrylate SR238NS reactive diluent mixed pre-slurry, crushed and dispersed evenly;

[0024] Then, add 4 parts of JRCure ITX, 3 parts of TPO, 3 parts of 907 photoinitiator, and then add 0.5 parts of leveling agent R2200, 0.5 parts of defoamer R2500, 0.1 parts 2,5-di-tertiary hydroquinone polymerization inhibitor, 3.9 parts of four-functional polyurethane acrylate Actilane276 and 5 parts of isobornyl acrylate SR506NS, mixed evenly, sand milled to make the raw materials fully wet, and then The sanded slurry is placed on a horizontal nano three-roller and rolled several times until the ink fineness is below 5 μm, and a UV offset printing ink suitable for different film substrates can be obtain...

Embodiment 2

[0026] First, place 18.9 parts of permanent yellow pigment in a sand mill at room temperature to disperse and grind it to a particle size below 5 μm; mix the ground permanent yellow pigment with 55 parts of polyester acrylate EBECRYL 446, 10 1 part of modified epoxy soybean oil acrylate and 2.5 parts of 1,6-hexanediol diacrylate SR238NS reactive diluent mixed pre-slurry, ground and dispersed evenly;

[0027] Then, add 1 part of JRCure ITX, 2 parts of TPO, 2 parts of 907 photoinitiator to the finely ground pre-slurry, and then add 0.5 parts of leveling agent R2200, 0.5 parts of defoamer R2500, 0.1 parts 2,5-di-tertiary hydroquinone polymerization inhibitor, 5 parts of four-functional polyurethane acrylate Actilane276 and 2.5 parts of isobornyl acrylate SR506NS, mixed evenly and sanded to make the raw materials fully wet, and then Place the sanded slurry on a horizontal nano three-roller machine and roll it several times until the ink fineness is below 5 μm, and then a UV offset...

Embodiment 3

[0029] First, put 14.9 parts of permanent red pigment in a sand mill at room temperature to disperse and grind to a particle size below 5 μm; mix the ground pigment and filler with 60 parts of polyester acrylate EBECRYL 446 and 5 parts of 1,6-Hexanediol diacrylate SR238NS reactive diluent mixed pre-slurry, crushed and dispersed evenly;

[0030] Then, add 2 parts of JRCure ITX, 3 parts of TPO, 3 parts of 907 photoinitiator to the finely ground pre-slurry, then add 0.5 parts of leveling agent R2200, 0.5 parts of defoamer R2500, 0.1 parts 2,5-di-tertiary hydroquinone polymerization inhibitor, 6 parts of four-functional polyurethane acrylate Actilane276 and 5 parts of isobornyl acrylate SR506NS, mixed evenly and then sanded to make the raw materials fully wet, and then Place the sanded slurry on a horizontal nano three-roller machine and roll it several times until the ink fineness is below 5 μm, and then a UV offset printing ink suitable for different film substrates can be obtai...

Abstract

The invention discloses UV offset printing ink suitable for different film substrates and a preparation method thereof. The ink mainly comprises prepolymer, a reactive diluent, a photoinitiator, pigments, paddings and assistants. The ink contains no solvents, has zero discharge of volatile organic compounds (VOC), is small in odor, energy-saving, environment-friendly, high in drying speed and flexibility, high-temperature resistant, good in adhesion and bright in color; the defects of non-resistance to high temperature, poor adhesion on a printing stock and the like of the existing UV offset printing ink can be overcome; and the ink is printed through offset printing on different film substrates such as non-absorptive materials like acrylonitrile-butadiene-styrene (ABS), polyvinyl chloride (PVC), polypropylene (PP), polyethylene terephthalate (PET) and o-phenylphenol (OPP), is widely applied to various film substrate printing, and is high in peel strength which can reach above 5N/cm<2>.

Description

technical field [0001] The invention relates to an ink, in particular to a UV offset printing ink suitable for different film substrates and a preparation method thereof. Background technique [0002] UV offset printing ink has no penetration when it is cured, and can be printed on non-absorbent printing materials, such as the printing of ID cards, etc., which is an area that ordinary offset printing inks cannot set foot in. At present, the ink products of domestic manufacturers can meet all kinds of high-end film printing, and can be widely used in various film substrates, but the general-purpose film UV offset printing ink with good adhesion performance to printed materials has not yet developed mature products, especially Ink products suitable for printing credit cards and other bank card ABS substrates are basically monopolized by foreign ink companies. Since credit cards and other bank cards are carried by many people, and the frequency of use is high, the stability of...
