Problems solved by technology

However, the photoinitiator and reactive monomer in the ink cannot fully participate in the reaction, especially the light is not easy to penetrate to the bottom layer of the coating, which may easily cause dryness and poor adhesion at the bottom of the coating
In addition, the surface of the inkjet coating is susceptible to oxygen interference to form oxygen inhibition, which will inhibit the reaction between the photoinitiator and the monomer, resulting in a non-dry and sticky surface

preparation example Construction

[0043] The present invention also provides a preparation method of the quick-drying non-stick UV inkjet ink described in the above technical solution, comprising the following steps:

[0044] (1) Dissolving the photoinitiator by monomer to obtain a pre-solution;

[0045] (2) Stir and mix the color paste with the pre-solution obtained in the step (1), and then filter to obtain a quick-drying non-stick UV inkjet ink.

[0046] The invention adopts the monomer to dissolve the photoinitiator to obtain the pre-solution. In the present invention, the monomers refer to the monofunctional monomers and polyfunctional monomers described in the foregoing technical solutions. In the present invention, there is no particular limitation on the specific implementation of the monomer-dissolving photoinitiator, and a method well known to those skilled in the art can be used.

[0047] After the pre-solution is obtained, the present invention stirs and mixes the color paste and the pre-solution...

Embodiment 1

[0065] The fast-drying non-stick inkjet ink consists of: 24% tetrahydrofurfuryl acrylate, 30% 1,6-hexanediol diacrylate, epoxy acrylate (one functional group in a single oligomer molecule) in parts by mass. Number≧2) 5.0%, polyurethane resin 5.0%, 2,4,6-trimethylbenzoyldiphenylphosphine oxide 8.0%, bis(2,4,6-trimethylbenzoyl)phenyl oxide Phosphine 2.0%, leveling agent BYK-3370.3%, stabilizer GENORAD16 0.7%, phenoxyethyl acrylate 14%, Solsperse240001.0%, white pigment (titanium dioxide) 10%.

[0066] The preparation method of the fast-drying non-stick inkjet ink is as follows: after mixing tetrahydrofurfuryl acrylate, 1,6-hexanediol diacrylate, epoxy acrylate oligomer, polyurethane resin, leveling agent and stabilizer , mixed with 2,4,6-trimethylbenzoyldiphenylphosphine oxide and bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide to obtain a pre-solution;

[0067] Mix the pre-solution with the color paste, and the stirring speed is 1000rpm. The colorants included phenoxyethyl a...

Abstract

The invention provides quick-drying non-sticky ultraviolet (UV) ink-jet ink and a preparation method thereof, and relates to the field of ink-jet ink. The ink provided by the invention comprises the following components: a single-functional monomer, a multi-functional monomer, a photoinitiator and color paste, wherein the number of functional groups of the multi-functional monomer is 2-20, and thephotoinitiator comprises a long-wavelength photoinitiator and a short-wavelength photoinitiator. A coating layer of the ink provided by the invention has a high curing rate and good surface dryness and bottom dryness. In addition, the surface adhesive force of coating layer of the ink is relatively high, a phenomena of bottom exposure cannot occur after a plurality of times of wiping, and the result of a paint adhesion testing is grade one or above (containing grade one).

Description

technical field [0001] The invention relates to the field of inkjet inks, in particular to a quick-drying and non-stick UV inkjet ink and a preparation method thereof. Background technique [0002] UV inkjet printing has the advantages of digital editing ability, high efficiency, high resolution, and low cost. The UV ink used has the advantages of no solvent volatilization, energy saving and carbon reduction, and a green environment. It is more and more popular among people. The drying of UV ink is a photochemical curing process. The UV light energy is absorbed by the photoinitiator in the UV ink, which is excited to form free radicals and polymerize with monomers or oligomers to form solid macromolecules. However, the photoinitiator and reactive monomer in the ink cannot fully participate in the reaction, especially the light is not easy to penetrate to the bottom layer of the coating, which may easily cause dryness and poor adhesion at the bottom of the coating. In additi...
