Abstract

The invention provides waterborne digital ink-jet printing sublimation ink and a preparation method thereof. The ink comprises the following components in percentage by mass: 1 to 10 percent of disperse dye, 2 to 15 percent of dispersing agent, 10 to 60 percent of deionized water, 10 to 50 percent of water soluble organic solvent, 0.1 to 5 percent of surface active agent, 0.05 to 0.5 percent of germicide, and 0.05 to 0.5 percent of defoaming agent. The preparation method comprises the following steps of: mixing 1 to 20 percent of dispersing agent, 10 to 40 percent of water soluble organic solvent, 0.1 to 2 percent of germicide, 0.1 to 2 percent of defoaming agent, and 30 to 50 percent of deionized water, adding 1 to 20 percent of disperse dye while stirring, and grinding the mixed solution to obtain color paste; uniformly mixing 15 to 50 percent of color paste, 10 to 30 percent of water soluble organic solvent, 0.1 to 5 percent of surface active agent and 20 to 50 percent of deionized water and filtering the mixed solution to obtain the waterborne digital ink-jet printing sublimation ink. When the waterborne digital ink-jet printing sublimation ink is used in a large-sized ink-jet printer using waterborne ink, the good printing smoothness and the water retention of a printing head are achieved, and the preparation process is simple.

Description

technical field [0001] The invention belongs to the field of digital inkjet printing ink and its preparation, in particular to a water-based digital inkjet printing sublimation ink and a preparation method thereof. Background technique [0002] Inkjet printing technology, with its characteristics of small batches, short process flow and fast delivery, can meet the personalized and diversified needs of consumers, and is widely used in various fields such as outdoor advertising inkjet printing and textile inkjet printing. [0003] Inkjet printing ink is the key to inkjet printing technology. According to different types of colorants, inks can be divided into two categories: pigment type and dye type, and according to different types of solvents, they can be divided into two categories: water type and solvent type. Water-based ink is favored by many consumers because of its low odor and low volatility, so it is environmentally friendly. Pigment-based ink is widely used in outdo...
