Embodiment 1

[0029] Preparation of yellow nano UV inkjet color paste:

[0030] 1) Add 50 parts of ethoxylated 1,6-hexanediol diacrylate, 5 parts of wetting agent, and 8 parts of dispersing agent into the dispersion container for pre-dispersion. The dispersion speed is 600r / min, and the dispersion time is 8min, to obtain a homogeneous mixture A; 2), add 15 parts of Pigment Yellow 150 to the mixture A, and disperse, the dispersion speed is 800r / min, and the dispersion time is 15, to obtain a homogeneous mixture B; 3), transport the mixture B to the bead Grinding in the mill is carried out segmented grinding. In the first stage, 0.6um zirconium beads are used to grind until the particle size distribution of the color paste reaches D90 and is less than 1000nm. In the second stage, 0.2um zirconium beads are used to grind until the particle size distribution of the color paste reaches D90 and is less than 200nm; 4) Filter and pack to obtain the finished product of yellow nano UV inkjet color pas...

Abstract

The invention relates to the field of printing, and particularly relates to nanometer UV ink-jet color paste and a preparing method thereof. The color paste includes a monomer, pigment powder, a wetting agent, and a dispersant. The particle size of the color paste can be a degree that D90 is less than 200 nm, and the color paste has high uniformity, and therefore a defect that the color paste is incompatible with other ink-jet components due to a large particle size and poor uniformity of the color paste is avoided. The color paste is widely applied in the field of UV ink jetting, has higher applicability, greatly improves quality of UV ink jet printing and ensures value of printed products.

Description

technical field [0001] The invention relates to the field of printing, in particular to a nano UV inkjet color paste and a preparation method. Background technique [0002] UV inkjet technology refers to an inkjet technology in which monomers, oligomers or polymer substrates are cured under ultraviolet light induction. This technology has a wide range of applications in the existing printing field, especially in digital printing technology. The application is more common. With the continuous innovation of technology, the continuous improvement and improvement of digital printing technology and UV inkjet technology, the combination of the two UV curing digital printing technology is developing rapidly, and it accounts for more and more in the digital printing industry. high specific gravity. [0003] The key to UV curing digital printing lies in the UV inkjet technology with excellent performance. In the process of preparing ink, the color paste not only has the effect of co...
