Problems solved by technology

For example, patent CN104927485A discloses a water-based UV ink for inkjet printing. The water-based UV ink for inkjet printing of the invention is used for inkjet printing. Cleaning, low energy consumption; but the invention uses alcohol as a diluent, which is highly volatile and affects storage stability
Patent CN103160168A discloses a water-based UV curing ink for inkjet printing direct plate-making technology and its preparation method and application. The ink of this invention has high printing precision and fast curing speed; however, more photoreactive monomers are used in the invention, which is irritating Large, harmful to the body, and the monomer is not completely cured during the curing process, which affects the adhesion and friction resistance of the printed pattern on the substrate

Abstract

The invention relates to a water-based UV ink for inkjet printing and a preparation method thereof. The water-based UV ink for inkjet printing is prepared from the following components in parts by weight: 1-5 parts of pigment, 1-15 parts of dispersing agent, 5-30 parts of water, 5-20 parts of cosolvent, 30-65 parts of prepolymer, 0.1-5 parts of photoinitiator and 0.1-5 parts of other aids. The prepolymer is composed of one or more of water-based polyurethane acrylate, water-based epoxy acrylate and water-based polyester acrylate; the cosolvent is composed of one or more of ethanediol, propanediol, diethylene glycol, polyethyleneglycol, triglycol, amide, diethylene glycol butyl ether, triethylene glycol butyl ether, N-methylpyrrolidone and cyclohexyl pyrrolidone; and the other aids are a defoaming agent, a polymerization inhibitor and a surfactant. The water-based UV inkjet ink has the advantages of environment friendliness and high printing smoothness, and has favorable adhesive force and friction resistance after being cured on the printed material; and the product has high storage stability.

Description

technical field [0001] The invention relates to a water-based UV ink, in particular to a water-based UV ink for inkjet printing and a preparation method thereof, belonging to the technical field of inkjet materials. Background technique [0002] UV light curing is the use of ultraviolet light to initiate rapid cross-linking polymerization of chemically active monomers and oligomers, which are instantly cured into solid materials. Traditional oil-based UV inkjet can be applied to a variety of substrates and is highly efficient and energy-saving. However, oil-based UV inkjet contains more acrylate reactive diluents, which not only pollute the environment, but also have a strong irritating effect on the skin and eyes, seriously affecting In good health. In addition, the residual reactive diluent will affect the properties of the cured coating such as friction resistance. [0003] With the improvement of people's awareness of environmental protection and quality of life, water...
