Problems solved by technology

Single-component digital grease has outstanding effects in one aspect, but the overall performance is not obvious
Single resin emulsion has various disadvantages. For example, water-based polyurethane emulsion inherits many excellent properties of solvent-based polyurethane, such as adjustable softness and hardness, strong wear resistance, excellent adhesion, better oil resistance, chemical resistance, etc. Physical and chemical properties; however, the solid content of polyurethane emulsion is low, the self-thickening property is poor, the luster of the latex film is insufficient, and the water resistance is not ideal
Polyacrylate resin has good water resistance, light stability, weather resistance and excellent physical and mechanical properties, but it is hot, sticky and brittle, has poor wear resistance, and is not resistant to solvents.

Abstract

A water-based pigment jet ink comprises 1-12wt% of a nanopigment, 1-5wt% of a dispersant, 1-15wt% of a modified polyurethane resin emulsion (solid content), 5-25wt% of a humectant, 5-15wt% of an osmotic agent, 0-2wt% of a surfactant, 0-2wt% of a PH adjusting agent, 0.1-0.5wt% of a sterilization antiseptic, and the balance deionized water. The ink has the advantages of excellent preservation stability and printing smoothness, particle nanometer level, complete chromatogram, substantially increased comprehensive properties comprising the light resistance, the water resistance, the chemical resistance, the scratch resistance, high brightness, the high and low temperature resistances, the ageing resistance and the like, and application range enlargement.

Description

technical field [0001] The invention relates to an inkjet ink, in particular to a water-based pigment inkjet ink. Background technique [0002] Due to its strong advantages, inkjet printing has made significant progress through nearly 30 years of development. It has been used in digital printing, digital printing, digital images, office documents, outdoor inkjet printing, surface decoration and other fields, providing great support for human production and life. convenient. Water-based pigment ink is favored by people because of its environmental protection, light-resistant and water-resistant colorants, and wide application range. [0003] As usage increases and scope expands, disadvantages of water-based pigment inks are discovered. For example, if the printer is not used for a long time, it is easy to block the nozzle; the ink on the paper is not resistant to scratches, has no luster, and the color is dull; it cannot print coated paper, plastic, glass, etc.; it cannot p...
