Embodiment 1

[0045] A preparation method of UV waterless offset disc magenta ink, comprising the steps of:

[0046] In terms of mass parts, take 15 parts of magenta pigments (RT-355-D magenta pigments, the manufacturer is Swiss Qiba company), 46 parts of epoxy acrylate and polyester acrylate Mixture (mass ratio is 1:1), 12 parts of monomer mixture composed of PDDA and TMPTA (mass ratio is 1:1), 6 parts of photoinitiator 2-methyl-1-[4-methylthio Phenyl]-2-morpholino-1-propanone, 15 parts of fumed silica, 1.5 parts of silicone acrylate, 2 parts of polyoxyethylene alkylphenol ether, 0.1 part of glycerol monostearate ester, 2.4 parts of phosphate methacrylate monomer, and then pre-disperse the above-mentioned components on a glass plate, and then grind them with a three-roll mill until the pigment is evenly dispersed. During the grinding process, adjust the three-roll mill The gap between the nip and the fineness of the ink are tracked and tested until the fineness of the ink reaches below 5 ...

Embodiment 2

[0048] A preparation method of UV waterless offset disc magenta ink, comprising the steps of:

[0049] In terms of parts by mass, take by weighing 16 parts of magenta pigment (RT-355-D magenta pigment, the manufacturer is Swiss Qiba company), 46.5 parts of the mixture composed of epoxy acrylate and polyurethane acrylate (mass ratio is 1:1), 10 parts of monomer mixture composed of DPGDA and EO3-TMPTA (mass ratio is 1:1), 5 parts of 2-hydroxy-2-methyl-1-phenyl- A photoinitiator mixture composed of 1-acetone, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (mass ratio 1:1), 17 parts of talc, 1.5 parts of siloxane acrylic acid ester, 1.9 parts of polyoxyethylene fatty alcohol ether, 0.1 part of polysorbate, 2 parts of dicyclopentadienyl acrylate, and then pre-disperse the above-mentioned components on a glass plate, and then grind them with a three-roll mill , until the pigment is evenly dispersed, adjust the nip gap of the three-roll mill in time during the grinding process, and ...

Embodiment 3

[0051] A preparation method of UV waterless offset disc magenta ink, comprising the steps of:

[0052] In terms of mass parts, take by weighing 10 parts of magenta pigment (RT-355-D magenta pigment, the manufacturer is Swiss Qiba company), 32 parts of epoxy acrylate, 9 parts of PDDA, 5 parts 2-methyl-1-[4-methylthiophenyl]-2-morpholino-1-propanone, 6 parts of kaolin, 1 part of silicone acrylate, 1 part of polyoxyethylene fatty alcohol Ether, 0.01 part of polysorbate, 1 part of dicyclopentadienyl acrylate, and then pre-disperse the above components on a glass plate, and then grind them with a three-roll mill until the pigment is evenly dispersed. Adjust the nip gap of the three-roller grinder, and track and test the fineness of the ink until the fineness of the ink reaches below 10 microns, stop grinding, and obtain a magenta ink for UV waterless offset printing discs.

Abstract

The invention provides UV anhydrous offset print compact disk magenta ink and a preparation method thereof. The UV anhydrous offset print compact disk magenta ink is mainly prepared from magenta pigments, pre-polymers, monomers, a photoinitiator, packing, a flatting agent, a moisturizing agent, a surfactant and an adhesion accelerant. The UV anhydrous offset print compact disk magenta ink is prepared by adopting particular raw materials and particular quantities and has the advantages of good scumming resistance, good rheological properties and excellent ink transfer performance and can be used for printing the surface of a compact disk; moreover, no moisturizing liquid is used in the print process, so that the production efficiency is high, the print quality is good, and the production cost is relatively low. The preparation method of the UV anhydrous offset print compact disk magenta ink adopts a direct mixing pre-dispersion and grinding way and is simple in process and suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of ultraviolet curing (UV) waterless offset printing inks, in particular to a magenta ink for UV waterless offset printing optical discs and a preparation method thereof. Background technique [0002] The traditional CD printing technology is usually carried out by screen printing, but due to the defects of the screen printing process itself, the printing speed is low, the tone reproduction is poor, and the printing quality is poor when using screen printing to print CDs. [0003] Waterless offset printing is a new printing technology, which has been widely used in CD printing in recent years. Waterless offset printing technology is actually a kind of lithographic printing technology. Compared with ordinary offset printing, it does not use fountain solution in traditional offset printing, but uses a special silicone rubber-coated printing plate with special rheological properties. Ink and a set of strict te...
