Problems solved by technology

Single-component digital grease has outstanding effects in one aspect, but the overall performance is not obvious
Single resin emulsion has various disadvantages. For example, water-based polyurethane emulsion inherits many excellent properties of solvent-based polyurethane, such as adjustable softness and hardness, strong wear resistance, excellent adhesion, better oil resistance, chemical resistance, etc. Physical and chemical properties; however, the solid content of polyurethane emulsion is low, the self-thickening property is poor, the luster of the latex film is insufficient, and the water resistance is not ideal
Polyacrylate resin has good water resistance, light stability, weather resistance and excellent physical and mechanical properties, but it is hot, sticky and brittle, has poor wear resistance, and is not resistant to solvents.

Abstract

The invention aims at providing an aqueous disperse dye ink-jet printing ink with excellent comprehensive performance capable of overcoming the defects of the traditional disperse dye ink-jet printing ink, and a preparation method of the aqueous disperse dye ink-jet printing ink. The aqueous disperse dye ink-jet printing ink has good ink storage stability and good printing fluency; the service time of a disperse dye ink-jet product is greatly prolonged; the aqueous disperse dye ink-jet printing ink can be cured under the irradiation of ultraviolet light (UV); the comprehensive performances of the ink, such as light resistance, water tolerance, chemical resistance, high and low-temperature resistance, rubbing scratch resistance, high brightness and ageing resistance of the ink are improved; the aqueous disperse dye ink-jet printing ink is applicable to an uncoated and non-printing coating medium and is applied to the fields such as digital printing, digital calico printing, digital images, office documents, outdoor inkjet, ceramic tile wallpapers, glass plastics and surface decoration.

Description

technical field [0001] The invention relates to an ink, in particular to a water-based disperse dye inkjet ink. Background technique [0002] The current disperse dye inkjet ink is generally dispersed with a dispersant for disperse dyes, and then added to the reagent of organic solvent and water to adjust the physical and chemical indicators of the inkjet ink, and then loaded into the inkjet printer for printing. Its use is as a digital printing ink for polyester, polyamide, and vinegar cloth, and as a thermal transfer colorant for printing on heat transfer paper; or as inkjet printer ink; disperse dyes are a kind of water micro Soluble dyes have high light fastness, water resistance, and ozone fastness. The dyes have good heat resistance and sublimation fastness, so they have a certain range of applications; [0003] As the use increases and the scope expands, the disadvantages of disperse dye water-based inkjet inks are found. For example, if the printer is not used for ...
