preparation example Construction

[0045] The present invention also provides a preparation method of the UV inkjet ink described in the above technical solution, comprising the following steps:

[0046] (1) After mixing monomers, photoinitiators, low glass transition temperature oligomers, dispersants and pigments, add grinding beads, and perform shock treatment to obtain a mixed material liquid;

[0047] (2) Filtrating the mixture liquid obtained in the step (1) to obtain UV inkjet ink.

[0048]In the invention, after mixing the monomer, photoinitiator, oligomer with low glass transition temperature, dispersant and pigment, adding grinding beads and performing shock treatment to obtain the mixed material liquid. The present invention has no special requirements on the specific implementation of the mixing, and the mixing methods well known to those skilled in the art can be used. In the present invention, the particle size of the grinding beads is preferably 0.2-0.4 mm, more preferably 0.3 mm. In the presen...

Embodiment 1

[0055] The UV inkjet ink consists of: tetrahydrofurfuryl acrylate 38.2%, isooctyl acrylate 15%, 1,6-hexanediol diacrylate 5%, epoxy acrylate 2253 6.0%, polyurethane Acrylate C2 12%, 2,4,6-trimethylbenzoyldiphenylphosphine oxide 10%, BYK-337 0.5%, GENORAD 16 0.7%, BYK-9151 0.6%, white pigment titanium dioxide 12%.

[0056] The preparation method of UV inkjet ink is: grinding beads with 4 times the weight of raw materials, tetrahydrofurfuryl acrylate, isooctyl acrylate, 1,6-hexanediol diacrylate, 2,4,6-trimethyl Benzoyl diphenyl phosphine oxide, epoxy acrylate 2253, polyurethane acrylate C2, BYK-337, GENORAD 16, BYK-9151 and white pigment titanium dioxide were poured into a shock bottle and sealed, and the shock bottle was placed in Shake in a shaker for 16 hours, and then filter through 0.7 μm glass fiber and 0.5 μm PP membrane to obtain UV inkjet ink.

[0057] Adopt identical method to carry out embodiment 2~12 and comparative example, wherein the raw material of embodiment 2...

Abstract

The invention provides an UV inkjet ink and a preparation method thereof, and relates to the technical field of inkjet inks. The UV inkjet ink comprises the following components in parts by mass: 30-80 parts of a monomer, 5-20 parts of a photo initiator, 1-30 parts of an oligomer, 0.1-5 parts of a dispersant, and 1-10 parts of a pigment. The embodiment results show that the coating formed by the UV inkjet ink has relatively good flexibility at room temperature and low temperature and relatively good ductility.

Description

technical field [0001] The invention relates to the technical field of inkjet inks, in particular to a UV inkjet ink and a preparation method thereof. Background technique [0002] UV inkjet ink has the advantages of no solvent volatilization, energy saving and carbon reduction, and green environment. It is more and more favored by people and its application range is wider and wider. Traditional UV inkjet inks can only be used in industries such as graphic output and advertising. For materials or industries that require ductility, the current UV inkjet inks cannot meet the requirements of flexibility and high ductility. For example, artificial PVC leather decoration, PU mobile phone cover printing, inkjet printing on plastic substrates, etc. After printing on a flat surface, these materials will be bent and formed. During the zigzag processing of traditional UV inkjet inks, problems such as zigzag cracks, extended exposure, and coating desorption are prone to occur. Conte...
