Abstract

The invention relates to high-adhesion high-gloss black UV inkjet ink which comprises, by weight, 10-20 parts of black color paste, 10-20 parts of polyurethane acrylate resin, 50-70 parts of reactivediluents, 6-10 parts of photoinitiator and 3-4 parts of auxiliaries. The reactive diluents include, by mass part, a first reactive diluent, a second reactive diluent and a third reactive diluent according to a consumption ratio of 2-3:1-2:2-3; the photoinitiator is at least one of 1-hydroxy-cyclohexylbenzophenone, 2, 4, 6-trimethylbenzoyl-diphenyl phosphine oxide and 2, 4, 6-trimethylbenzoyl ethylphenyl phosphoinate; the auxiliaries include defoamer, leveling agent, adhesion accelerant and polymerization retarder. The invention provides a preparation method and application of the high-adhesion high-gloss black UV inkjet ink. The black UV inkjet ink has the advantages of high gloss value, high adhesion and high hardness.

Description

technical field

[0001] The invention relates to the field of UV curing materials, in particular to a high-adhesion high-gloss black UV inkjet ink and its preparation method and application. Background technique

[0002] Ultraviolet curing (UV) ink refers to the use of ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink binder into polymers under ultraviolet irradiation, so that the ink is dried and formed into a film. The UV inkjet printing system can print any image on tinplate, crystal, glass, acrylic, metal, ceramics, canvas, and UV inkjet printing can also realize personalized on-demand printing, which is used for some carry-on items to highlight users Personality, such as phone case, vanity mirror, lighter, wallet, etc.

[0003] At present, the price of black UV inkjet inks produced abroad is generally more expensive, about 300 yuan / kg. Although they have good comprehensive performance, in order to make the surface of the print...

Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with specific embodiments.

[0039] According to the proportioning relationship in Table 1 to Table 9, add polyurethane acrylate resin, active diluent and dispersant to the reaction kettle in proportion, and then stir and disperse with a disc stirring paddle. The dispersion time is 20 to 30 minutes. The dispersion system Control the temperature at 20°C to 40°C to obtain component A.

[0040] Add carbon black pigment to component A in proportion, and then stir and disperse with a disc stirring paddle. The dispersion time is 20-30 minutes, and the temperature of the dispersion system is controlled at 20°C-40°C to obtain component B.

[0041] Add component B into the grinder for high-speed grinding. The grinding time is 60-90 minutes. The temperature of the grinding system is controlled at 20°C-40°C to obtain a black color paste.

[0042]Add black color paste and urethane acrylate resin into th...
