Abstract

The invention belongs to the technical field of inkjet printing, and discloses a water-based inkjet ink for inkjet printing. The water-based inkjet ink for inkjet printing is composed of the following raw materials in percentage by mass: 15-30% of slurry, 0.3-1.5% of wetting agent, 4-20% of water-based polyurethane resin, 0.1-3% of pH regulator, 5-20% of viscosity modifier, 0.1-0.5% of preservative and the balance of deionized water. The slurry is composed of the following components in percentage by mass: 5-15% of pigment, 2-5% of emulsion stabilizer, 6-17% of dispersing agent, 0.1-0.7% of defoaming agent, 2-10% of water-based acrylic resin and the balance of deionized water. The invention also discloses a preparation method of the water-based inkjet ink. The water-based inkjet ink has the advantages of high smoothness, high stability, favorable weather resistance and favorable color expressiveness, and can satisfy the requirements for industrial high-speed inkjet printing.

Description

【Technical field】 [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to a water-based inkjet ink for industrial high-speed inkjet printing and a preparation method thereof. 【Background technique】 [0002] Industrial inkjet printing has incomparable advantages over traditional printing. Printed products are increasingly developing in the direction of multi-variety, small batches, and individualization. Digital printing based on inkjet technology has no plate, no pressure, strong adaptability, and automation. High, the miniaturization of printing devices and other characteristics have launched a strong challenge to traditional printing, and it has increasingly become the mainstream printing business; The advantages of waste, low cost and rapid development. [0003] The inkjet inks used in industrial inkjet printing mainly include UV light-curable inks, solvent-based inks, and water-based inks. The water-based ink has the advanta...
