High temperature solidify water ink-jet ink containing inorganic pigment

Abstract

The invention relates to a high temperature solidification water based jet ink containing an inorganic pigment, and at least it includes inorganic pigment, water solubility synthetic resin, organic morphon and interpolymer. The inorganic pigment includes single-type, solid lyso-type pigment composed by single metal oxide and sulfide, or padding type pigment at least composed by two kinds of metal oxide and sulfide, and of course includes various kinds of metal small powder. Water solubility synthetic resin includes at least one of alkyd resin, vinyl resin, acrylic resins and beetle, of course includes the modifier of these resins. The organic morphon and interpolymer include several acrylic acidacrylic acid polymers, such as TPGDA, EO-HDDA, DMAEMA, NPGDA and so on.

Description

【Technical field】 [0001] The invention relates to an ink-jet ink, in particular to a high-temperature solidified water-based ink-jet ink containing inorganic pigments, which can effectively improve the high-temperature resistance of the ink and adopts an aqueous solvent that meets environmental protection requirements. 【Background technique】 [0002] With the continuous development of inkjet printing technology, the application of this technology has been continuously introduced into new fields. At the same time, the high temperature resistance, acid and alkali resistance, high wear resistance and environmental protection performance of inkjet ink put forward higher requirements. [0003] Inkjet inks are generally divided into water-based inks and solvent-based inks. The solvent used in water-based ink is mainly water, which is more in line with environmental protection requirements; while solvent-based inks mostly use volatile organic solvents that are insoluble in water, ...

AI Technical Summary

Problems solved by technology

The solvent used in water-based ink is mainly water, which is more in line with environmental protection requirements; while solvent-based inks mostly use volatile organic solvents that are insoluble in water, such as benzene solvents and ketone solvents, which cause environmental pollution. There are also potential hazards to users

[0004] As far as inkjet ink colorants are concerned, there are mainly two types of dyes and organic pigments. Generally speaking, dye-based inks are easy to dissolve in water and show brighter colors, but usually lack good light resistance and Water resistance, so when the printed screen is exposed to water, the dye will be dissolved again and the printing effect will be affected

Although organic pigment inks have good light resistance and water resistance, their high temperature resistance, acid and alkali resistance and abrasion resistance are far inferior to those of inorganic oxide pigments.
