preparation example Construction

[0046] In the present invention, the preparation method of the white color paste preferably comprises the following steps:

[0047] (1) dissolving the dispersant by using the color paste monomer to obtain a pre-solution;

[0048] (2) Stir and mix the pre-solution obtained in the step (1) with the pigment, color paste additive, and obtain a pre-dispersion;

[0049] (3) Grinding and filtering the predispersed liquid obtained in the step (2) to obtain a white slurry.

[0050] The invention adopts colorant monomer to dissolve the dispersant to obtain a pre-solution.

[0051] The present invention has no particular limitation on the specific implementation of the dissolving and dispersing agent for the color paste monomer, and the methods well known to those skilled in the art can be adopted.

[0052] After the pre-solution is obtained, the present invention stirs and mixes the pigment, color paste additives and the pre-solution to obtain the pre-dispersion liquid.

Abstract

The invention provides a UV white inkjet ink, which comprises the following components in parts by mass: 30-70 parts of monomer, 5-15 parts of photoinitiator, 1-10 parts of resin, and 20-50 parts of white color paste ; The structure of the monomer contains one or more of ring structure, hydroxyl group, ethoxyl group, propoxyl group, amine group and amino group; the photoinitiator is an acyl phosphine oxide photoinitiator, α One or more of hydroxyketone photoinitiators, α-aminoketone photoinitiators and thioxanthone photoinitiators; the white color paste includes pigments, and the pigments are titanium dioxide. The UV white inkjet ink provided by the present invention has good stability, and after aging for 7 days, it still has good stability; the UV white inkjet ink provided by the present invention has good curing adhesion; and the UV white inkjet ink provided by the present invention Ink ink has good whiteness and shading rate, and there will be no problems of clogging nozzles and ink breakage.

Description

technical field [0001] The invention relates to the field of inks, in particular to a UV white inkjet ink. Background technique [0002] UV white inkjet ink has good masking ability, which can hide the defects on the substrate, and improve the contrast and vividness of color inkjet ink in surface printing mode or back printing mode. In the surface printing mode, the color image is attached to a coating of white inkjet ink, so that the color image stands out against a white background; in the reverse printing mode, the color image is printed on a transparent substrate, and then the white inkjet ink Ink ink adheres to this color image, and the final image is viewed through the transparent substrate. However, the raw material monomers, oligomers, resins or additives in UV white inkjet inks often have a slight color, making the contrast lower and the white ink yellowish. [0003] In order to solve the above-mentioned technical problems, the white inkjet ink preferably adopts a...
