preparation example Construction

[0047] The present invention also provides a preparation method of the LED-UV inkjet ink described in the above technical solution, comprising the following steps:

[0048] (1) Dissolving the photoinitiator by monomer to obtain a pre-solution;

[0049] (2) Stir and mix the resin and the color paste with the pre-solution obtained in the step (1) to obtain the LED-UV inkjet ink.

[0050] The invention adopts the monomer to dissolve the photoinitiator to obtain the pre-solution.

[0051] 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.

[0052] After the pre-solution is obtained, the present invention stirs and mixes the resin and the color paste with the pre-solution to obtain the LED-UV inkjet ink.

[0053] In the present invention, the rotational speed of the stirring and mixing is preferably 500-1500 rpm, more preferably 800-13...

Abstract

The invention provides LED-UV jet ink, which comprises, by weight, the following components: 10-85 part of a monomer, 5-20 parts of a photoinitiator and 10-40 parts of color pulp. The monomer comprises one or more of a ring structure, hydroxyl group, ethoxy group, propoxy group, amine group and amino group; the photoinitiator is an acyl phosphine oxide photoinitiator, an alpha-hydroxyketone photoinitiator, an alpha-amino ketone photoinitiator or a thianthracene photoinitiator. The LED-UV jet ink has good stability, and under the action of LED-UV light and the photoinitiator, the LED-UV jet ink, composed of the monomer, resin and color pulp, can be attached well to the surface of a substrate and improve the adhesion of the LED-UV jet ink. The test results show that the LED-UV jet ink has good stability and strong adhesion.

Description

technical field [0001] The invention relates to the field of inks, in particular to an LED-UV inkjet ink and a preparation method thereof. Background technique [0002] UV inkjet ink does not contain solvents. After printing on the medium, it is formed by UV light curing and can transfer 100% of the ink. Therefore, UV inkjet ink is also called environmentally friendly ink without solvent pollution. [0003] Compared with UV inkjet ink, LED-UV inkjet ink not only has the above-mentioned advantages of UV inkjet ink, but also LED-UV inkjet ink can be cured and shaped by LED-UV curing lamp when in use, LED-UV curing lamp It has the function of saving energy and carbon. Therefore, LED-UV inkjet ink is more conducive to energy saving and environmental protection. But in the market share, LED-UV inkjet ink only accounts for a small part. The main reason is that the stability and adhesion of LED-UV inkjet ink are not good, and problems such as nozzle blockage, ink droplet sprayin...
