preparation example Construction

[0032] During the preparation of UV ink, the foam will hinder the dispersion of the colorant, and the foam will cause color problems and printing drying problems during the printing process, resulting in pinholes and dullness of the printed matter. The defoamer has the function of suppressing foam or defoaming, preventing the formation of foam and rapidly breaking the formed foam. Improper type and amount of defoamer will have adverse effects, such as "fish eyes" and pinholes. When the antifoaming agent is selected, it is based on the basic principles of not affecting the color of the ink, low viscosity, non-volatile, non-toxic, non-flammable, and soluble in water. The antifoaming agent in the present invention is natural oil, polyether fatty alcohol polyether, Dimethicone or Polyoxyethylene Propylene Glycerin.

[0033] The main function of the wetting and dispersing agent is to reduce the surface tension of the substance, prevent the flocculation of the pigment, and keep the...

[0039] Step 1. Take the following components by weight percentage: 50% water-based photocurable resin, 30% active monomer, 0.5% photoinitiator, 5% direct dye, 12.5% ​​auxiliary agent, 2% diluent, wherein, auxiliary The agent is 2% photosensitizer, 0.5% polymerization inhibitor, 0.2% leveling agent, 1.2% defoamer, 2% wetting and dispersing agent, 1% anti-abrasion agent, 0.6% of the total weight of water-based UV sensitizer A mixture of thixotropic agent and 5% light stabilizer.

[0040] Among them, the water-based photocurable resin uses silane-modified acrylic resin; the active monomer uses dipropylene glycol diacrylate (DPGDA); the photoinitiator uses 2,4-diethylthioxanthone (DETX); the direct dye Use C.I. Direct Yellow 86 (Project Yellow 1, DYS); use triethanolamine as photosensitizer, use hydroquinone as polymerization inhibitor, use silicone acrylate as leveling agent, use natural oil as defoamer, and wetting and dispersing agent Polyacrylate is used, oleic acid amide is ...

[0046] Step 1. Weigh the following components by weight percentage: 30% water-based photocurable resin, 35% active monomer, 4% photoinitiator, 5% direct dye, 26% auxiliary agent, wherein the auxiliary agent is water-based UV 4% photosensitizer, 1% polymerization inhibitor, 0.5% leveling agent, 2% defoamer, 6% wetting and dispersing agent, 1.5% anti-abrasion agent, 1% thixotropic agent and 10% of sensitizer gross weight % light stabilizer mixture.

[0047] Among them, the water-based photocurable resin uses silyl-modified acrylic resin; the active monomer is a mixture of dipropylene glycol diacrylate (DPGDA) and tricarboxymethylpropane triacrylate (TMPTA) in a weight ratio of 1:1 ; The photoinitiator is 2,4-diethylthioxanthone and 2-phenyl-2,2-dimethylamino-1-(4-morpholine phenyl)-1-butanone in a weight ratio of 1: 3 mixtures; direct dyes use C.I. Direct Red 2 (Paper Red 4BS, CKC); photosensitizers use triisopropanolamine, polymerization inhibitors use p-methoxyphenol, and lev...

Abstract

The invention discloses water-based UV (ultraviolet) ink, consisting of the following components according to a certain weight percentage: water-based light-cured resin, an activated monomer, a photoinitiator, pigments, assistants and a diluent. The assistants consist of a photosensitizer, a polymerization inhibitor, a leveling agent, a defoaming agent, a wetting and dispersing agent, an anti-rubagent, a thixotropic agent and a light stabilizer; and the pigments consist of direct dye, reactive dye and paint. The invention also discloses a preparation method of the water-based UV ink, which comprises the following steps of: weighing the components and sequentially adding the photoinitiator and the water-based light-cured resin into the activated monomer; dissolving the direct dye or the reactive dye in the diluent and then adding the dissolved substances, adding the assistants, evenly stirring the mixture and collecting the materials to obtain the water-based UV ink; or taking a certain amount of the wetting and dispersing agent, dispersing the pigments in the wetting and dispersing agent and then adding the dissolved substances, and evenly stirring the mixture; and adding the rest assistants and the diluent, stirring and then heating the mixture, and collecting the materials to obtain the water-based UV ink. According to the invention, the problem of incapability of the water-based UV ink to multiple kinds of printing modes in the prior art is solved. The preparation method is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of printing and reproduction, relates to a water-based UV ink, and also relates to a preparation method of the water-based UV ink. Background technique [0002] As a new type of environmentally friendly ink, UV ink has the advantages of energy saving, no solvent emission, no environmental pollution, high production efficiency, excellent printing performance, and low equipment investment, and has always been valued by countries all over the world. In the early 1970s, it has been successfully commercialized and supplied to the market. UV curable inks have been introduced into the printing industry, and have different degrees of realistic potential benefits for different application fields. In three-dimensional printing, the combination of traditional flat-bed proofing machine and UV curing machine is used to realize offset printing UV lithographic proofing that is instantly cured and dried after UV ink proofin...
