Abstract

The invention discloses water-based inkjet ink and a preparation method thereof. The ink is prepared from, deionized water, polyethylene glycol 200, a pigment, ethylene glycol dimethacrylate, ethyl methacrylate, neopentyl glycol diacrylate, lauryl alcohol polyoxyethylene, triethanolamine, polyoxyethylene polyoxypropylene pentaerythritol ether, ethylene bis stearamide, 4-[(4,6-bis(octylthio)-1,3,5-triazine-2-yl) amino]-2,6-ditert-butyl phenol, octyl methoxycinnamate, titanium dioxide and the like. The water-based inkjet ink has the advantages that the water-based inkjet ink meets the requirements of environmental protection, printing pollution is greatly reduced, the octyl methoxycinnamate and the titanium dioxide are added into the ink and are combined to form a protective film for ultraviolet light blocking on the dye surface layer of the ink, so that the ink does not fade under the outdoor light exposure, is resistant to scratching and is not easily oxidized, and output performed by using the ink does not need printing materials with special coatings.

Description

technical field [0001] The invention relates to the field of printer consumables. More specifically, the present invention relates to a water-based inkjet ink and its preparation method. Background technique [0002] Inkjet printing is printing achieved without the printing device contacting the substrate on which the printed characters are deposited, by jetting a stream of ink droplets onto a surface and by controlling the direction of the stream so that the droplets A desired printed image is formed on the surface. Due to the particularity of the inkjet printing method, the inkjet ink has higher requirements, such as ink viscosity, resistivity, component compatibility, solubility, and wettability to the substrate. [0003] According to the nature of the ink, inkjet ink can be divided into three types: water-based inkjet ink, solvent-based inkjet ink, UV inkjet ink, solvent-based inkjet ink is not environmentally friendly and pollutes the environment, UV inkjet ink requir...
