Embodiment 1

[0052] Take 42 parts (weight) of polyester acrylate, add 5 parts (weight) of epoxy acrylate, 20 parts (weight) of high-viscosity monofunctional urethane acrylate, 3 parts (weight), 10 parts (weight) of photoinitiator, disperse at high speed, stir evenly, until the photoinitiator is completely dissolved. Under the condition that the rotation speed of the mixer is less than 300 r / min, 4 parts (weight) of filler and 16 parts (weight) of yellow organic pigment are put in. After the materials are evenly mixed, under the condition that the speed of the mixer is >600r / min, disperse at a high speed, fully wet the powder, and then grind it with a three-roller machine to a fineness of ≤6um to obtain the finished product.

Embodiment 2

[0054] Take 42 parts (weight) of polyester acrylate, add 5 parts (weight) of epoxy acrylate, 20 parts (weight) of high-viscosity monofunctional urethane acrylate, 3 parts (weight), 10 parts (weight) of photoinitiator, disperse at high speed, stir evenly, until the photoinitiator is completely dissolved. When the speed of the mixer is less than 300 r / min, 4 parts (weight) of filler and 16 parts (weight) of red organic pigment are put in. After the materials are evenly mixed, under the condition of the mixer speed > 600r / min, disperse at high speed to fully wet the powder. Then use a three-roller to grind to a fineness of ≤6um, and the finished product is obtained.

Embodiment 3

[0056] Take 42 parts (weight) of polyester acrylate, add 5 parts (weight) of epoxy acrylate, 20 parts (weight) of high-viscosity monofunctional urethane acrylate, 3 parts (weight), 10 parts (weight) of photoinitiator, disperse at high speed, stir evenly, until the photoinitiator is completely dissolved. When the speed of the mixer is less than 300 r / min, 4 parts (weight) of filler and 16 parts (weight) of blue organic pigment are put in. After the materials are evenly mixed, under the condition of the mixer speed > 600r / min, disperse at high speed to fully wet the powder. Then use a three-roller to grind to a fineness of ≤6um, and the finished product is obtained.

Abstract

The invention relates to UV cured lithographic ink and purposes thereof. The ink is a compound which comprises the following components by the weight percent: 30 to 50 of polyester acrylic ester, 0 to 15 of epoxy acrylic ester, 2 to 22 of high-viscosity monofunctional polyurethane acrylic ester, 0 to 10 of acrylic monomer, 10 to 15 of photoinitiator, 2 to 5 of filler and 16 to 22 of pigment. The UV curing glue printing ink of the invention can be cured at high speed, can meet the requirements of high-speed packaging, printing and environment protection, does not contain VOC, has little irritation to the human skin, and can be used as lithographic ink for the high-speed printing, and paper and plastic printing of packaging and printing.

Description

【Technical field】 [0001] The invention relates to printing ink, in particular to a UV-curable ink that meets the requirements of high-speed printing and complex forming processing of packaging printing and meets the requirements of environmental protection and its application. 【Background technique】 [0002] At present, a large number of solvent-based inks are used in the printing industry, and the high-boiling point solvent used contains certain benzene compounds. When the benzene compounds exceed the standard, it will pollute the surrounding environment and endanger people's health. With the rapid development of the packaging and printing industry, higher requirements have also been placed on printing inks. Among them, UV (ultraviolet light) curable offset printing ink has been widely used in many fields such as cigarette packs, wine packs, cosmetic packaging, pharmaceutical packaging and self-adhesive labels because of its incomparable advantages over traditional solvent-...
