Abstract

The invention belongs to the technical field of UV color paste, and particularly relates to UV nano red paste and a preparation method thereof and UV ink. The UV nano red paste is prepared from the following raw material components in percentage by mass: 50-87% of acrylate monomer, 3-20% of dispersing agent, 10-35% of red pigment and 0-1% of auxiliary agent, wherein the auxiliary agent comprises an oxygen polymerization inhibitor. In the UV nano red paste, the red pigment has sufficient wettability, good dispersion stability and proper viscosity and leveling property in each monomer, can be directly applied to a UV ink formula, has excellent fluency, stability and color performance in UV ink, and can be applied to soft ink, medium ink and hard ink. When the UV color paste is applied to UVink, the UV ink has good ink-jet printing performance, the bonding performance of the ink and a matrix is good, and excellent wet fastness is provided for soft and neutral ink.

Description

technical field [0001] The application belongs to the technical field of UV color paste, and in particular relates to a UV nano-red paste, a preparation method thereof, and a UV ink. Background technique [0002] UV inkjet technology refers to monomer, oligomer or polymer matrix, an inkjet technology that is cured under the induction of ultraviolet light. This technology has a wide range of applications in the existing printing field, especially in digital printing technology. application is more common. With the continuous innovation, progress and improvement of digital printing technology, higher and higher requirements are put forward for UV ink. [0003] Color paste refers to mixing the toner with solvent or diluent, adding dispersant and stabilizer to make it liquid, after being stirred evenly by the disperser, it enters the nano grinder and zirconium beads high-speed shear Cut to meet its finished product requirements. Organic pigment pastes are used in a wide range...
