Problems solved by technology

Disperse dyes that meet the requirements of inkjet color matching have a compact crystal structure and are insoluble in water. The disperse dye particles will be deposited, resulting in a decrease in the color density of the printed image, and serious color imbalance will occur when the machine is shut down and then printed.
In addition, the printer nozzle has very high requirements on the fineness and stability of the particles, and in severe cases, the nozzle will be clogged

Abstract

The invention discloses a grinding dispersant for sublimation ink. The grinding dispersant is prepared from the following raw materials in parts by mass: 10-40 parts of water-based acrylic resin, 5-50parts of alkynediol polyoxyethylene ether, 0-50 parts of isomeric alcohol polyether, 0-30 parts of trisiloxane polyoxyethylene ether and 35-65 parts of a solvent. The dispersing agent has a very gooddispersing and stabilizing effect. The grinding dispersant can achieve a stable dispersion effect on the basis of evaluation results of the placement stability, the centrifugal stability and the viscosity stability.

Description

technical field [0001] The invention belongs to the technical field of dispersants, in particular to a grinding dispersant for thermal sublimation ink. Background technique [0002] Sublimation dyes can be used in the preparation of sublimation inkjet inks, which usually disperse sublimation dyes in the water phase, and print exquisite images on specific transfer media by inkjet printers, stacking the media on On the transferred body, dyeing is achieved by heat sublimation transfer. As far as the printing effect is concerned, the color dye-sublimation printer can meet the delicate and delicate skin texture required for portrait printing. It has bright and rich colors, excellent performance such as water resistance, abrasion resistance, and sun resistance. It is gentle on the skin and friendly to the environment. [0003] Most of the sublimation dyes are disperse dyes, and disperse dye inkjet inks are currently a hot spot in the research of printing, dyeing and digital print...
