Abstract

The invention discloses an ink-jet ink composition and a preparation method thereof. The ink-jet ink composition is divided into a component A and a component B, wherein the component A comprises a carbon black pigment, glycerine ethoxylate, white oil, epoxy modified waterborne acrylic resin and the like; the component B comprises pine soot, dimethicone, ethylene glycol monobutyl ether, waterborne polyurethane dispersion liquid and the like. The preparation method comprises the following steps: preparing the component A and the component B respectively at first, and then mixing the two components to obtain the ink-jet ink composition. The ink-jet ink composition disclosed by the invention is high in surface tension, low in viscosity, rapid to dry, high in adhesive force, high in gloss, excellent in levelling property, free from cracking during a use process, free from ink spreading and pinhole phenomena, and adequate in strength and durability; the two components of the ink-jet ink composition disclosed by the invention are mixed before use, thus increasing the retention time of the ink-jet ink composition, and then prolonging the service life thereof.

Description

Technical field [0001] The invention relates to an ink composition, in particular to an inkjet ink composition and a preparation method thereof. Background technique [0002] Inkjet printing is printing that is achieved under the condition that the printing device does not touch the substrate on which the printed characters are deposited. This technology ejects a stream of ink droplets to the surface and controls the direction of the stream to make the droplets fall on the surface. The desired printed image is formed on the surface. Due to the particularity of inkjet printing methods, there are higher requirements for inkjet inks, such as ink viscosity, resistivity, compatibility of components, solubility, and wettability to substrates. [0003] The current inkjet inks have the following problems: slow drying speed after inkjet printing, poor adhesion, poor leveling of the ink, no ink diffusion and pinhole phenomenon in severe cases, and when the ink is printed on the article dur...
