Problems solved by technology

[0002] In the prior art, solvent-based or oil-soluble UV-curable inks are usually used for packaging printing inks. The outstanding advantages of this ink are environmental protection and fast drying speed. The reason for environmental protection is that the ink system does not contain volatile organic solvents, but uses Active diluents are used to adjust the viscosity of the ink. The disadvantage is that despite the advantages of environmental protection, the diluents of organic compounds are still used after all, which has a strong smell and has a certain stimulating effect on the human body. It is easy to cause skin allergies. At the same time, UV curing The high energy produces ozone, which destroys the ecological environment and consumes a lot of energy

Embodiment 1

[0007] A water-based long-wave ultraviolet drying packaging printing ink, firstly mix 100 parts of water-based polyurethane acrylate resin that can be dried by LED ultraviolet light source, 15 parts of sorbitan trioleate surfactant, 60 parts of water, and 35 parts of ethanol, and fully stir After uniformity, add 50 parts of organic pigment BGS phthalocyanine blue, 3 parts of water-based fluorine-containing defoamer, 4 parts of water-based polysiloxane leveling agent, and 3 parts of water-based fluorine-containing defoamer, and then grind, generally 3-4 Road, the grinding fineness is required to be less than 15um, and finally add 20 parts of HZH90 initiator, 3 parts of p-tert-butylcatechol, and mix well again.

Embodiment 2

[0009] A water-based long-wave ultraviolet drying packaging printing ink. First, 120 parts of water-based epoxy acrylate resins that can be dried by LED ultraviolet light sources, 20 parts of sorbitan monooleate surfactants, 80 parts of water, and 40 parts of ethanol are mixed. After stirring evenly, add 40 parts of organic pigment permanent red, 4 parts of water-based fluorine-containing defoamer, 5 parts of water-based polysiloxane leveling agent, and 5 parts of water-based fluorine-containing defoamer, and then grind, generally 3-4 parts Road, the grinding fineness is required to be less than 15um, and finally add 25 parts of HZH90 initiator, 3 parts of p-tert-butylcatechol, and mix well again.

[0010] The water-based ink prepared above can easily adjust the viscosity of the ink with water. The general viscosity is 500-6000mpaS / 25°C. It is printed on the surface of paper, plastic and other substrates by screen printing. First, the printed matter is at 90-100°C. Constant te...

Abstract

The invention relates to aqueous long-wave-ultraviolet-drying package printing ink, belonging to the field of printing inks. The ink can be initiated to be dried under the long-wave ultraviolet light of 395-405nm and is especially suitable for being dried by long-wave low-energy LED (Light Emitting Diode) ultraviolet light sources, no ozone is generated during printing, and the ink takes water and ethanol as solvents and contains aqueous UV-cured acrylic resin, a photoinitiator and assistants. The ink is high in drying speed, is safe and environment-friendly and can meet the printing requirements of printed objects made of paper and plastics.

Description

technical field [0001] The invention belongs to the field of printing inks, in particular to a water-based long-wave ultraviolet drying printing ink for packaging. Background technique [0002] In the prior art, solvent-based or oil-soluble UV-curable inks are usually used for packaging printing inks. The outstanding advantages of this ink are environmental protection and fast drying speed. The reason for environmental protection is that the ink system does not contain volatile organic solvents, but uses Reactive diluents are used to adjust the viscosity of the ink. The disadvantage is that despite the advantages of environmental protection, the diluents of organic compounds are still used after all, which has a strong smell, has a certain stimulating effect on the human body, and is easy to cause skin allergies. At the same time, UV curing The high energy produces ozone, which destroys the ecological environment and consumes a lot of energy. Contents of the invention ...
