Abstract

The invention relates to the technical field of UV nano color paste, and in particular, relates to UV nano black slurry as well as a preparation method and application thereof, and provides the UV nano black slurry which comprises 50-90 parts of an acrylate monomer, 3-20 parts of a dispersant, 10-30 parts of carbon black, 0.5-1 part of an auxiliary agent, and 0.5-2 parts of a synergistic dispersant. According to the UV nano black slurry provided by the invention, the acrylate monomer is used as a main component, the carbon black is used as a toner, the synergistic dispersant, the auxiliary agent and the synergistic dispersant are used, and the synergistic effect of all the components can control the high dispersion degree and uniform dispersion of a product, so that the high-blackness nano black slurry is obtained, and the obtained nano black slurry is ensured to be small in particle size and stable in property; and the UV nano black slurry can be directly added into a UV ink-jet ink formula, has excellent brightness and blackness after being cured, and improves the dry and wet rubbing color fastness of an ink.

Description

technical field [0001] The application belongs to the technical field of UV nano-color paste, and in particular relates to a UV nano-black paste and its preparation method and application. Background technique [0002] UV inkjet (UV curable digital ink-jet ink) refers to ultraviolet curable digital inkjet, which is developed on the basis of ultraviolet curable printing ink. It has a history of more than 50 years. It is an ancient printing ink variety and has been widely used Used in printing industry. [0003] Among them, the most important thing in the UV curing digital inkjet process is the UV digital ink used. The biggest feature of UV-curable digital inkjet is viscosity and rheology. The viscosity of printing ink is relatively high, and the rheology is a pseudoplastic fluid, while inkjet requires low viscosity and high tension. The rheology is as close to Newtonian fluid as possible, requiring good fluidity. In addition, the color paste used in the ink has low chroma ...
