Problems solved by technology

For dye-based water-based inks, because the dye molecules will quickly decompose and volatilize under the irradiation of ultraviolet light, their light fastness is poor and not suitable for outdoor use; for pigment-based water-based inks, due to the pigment and non-absorbing base There is no chemical bond or strong intermolecular force between the materials, the ink cannot adhere well to the surface of the non-absorbent substrate, and the scratch resistance is poor, so pigment-based water-based ink is used on the surface of the non-absorbent substrate to obtain High-resolution, outdoor-durable images present some difficulties

Abstract

The invention relates to latex-type waterborne pigment oil ink for the inkjet printing of a non-absorbed substrate, which is prepared from the following components in percentage by weight: 1-15 percent of pigment dispersant, 0.01-2.0 percent of surface active agent, 10-40 percent of water-soluble co-solvent, 0.1-30 percent of water-based polymer emulsion and the balance of deionized water. The preparation method comprises the following steps of: stirring and mixing the surface active agent, the water-soluble co-solvent and the deionized water under a normal temperature; then, slowly adding the waterborne polymer emulsion, continuously stirring; and finally, adding the pigment dispersant, fully mixing the contents to form an even dispersing system and filtering the even dispersing system to obtain latex-type waterborne pigment oil ink. The latex-type waterborne pigment oil ink for the inkjet printing has wide range of suitable substrates, is environment-friendly in the oil ink preparation process and the printing process and has good printing smoothness and high accuracy; and printed images on the non-absorbed substrate have excellent resistance to rubbing, scraping, sunshine and water and are suitable for outdoor use.

Description

technical field [0001] The invention belongs to the field of pigment ink for inkjet printing and its preparation and application, in particular to an emulsion-type water-based pigment ink for inkjet printing of non-absorbing substrates and its preparation and application. Background technique [0002] Inkjet printing inks for large inkjet printers can generally be divided into three categories according to their main components: water-based inks, solvent-based inks and UV-curable inks. Currently widely used solvent-based inks generally have disadvantages such as strong odor, high content of volatile organic compounds, and being unfriendly to the environment. Although the weak solvent ink is a relatively environmentally friendly solvent ink, compared with the general solvent ink, many environmental problems are reduced, but not completely resolved. UV-curable inks solve the problems of VOC and ink drying speed, but at the same time, there are disadvantages such as high energ...
