Embodiment 1

[0052] Get 42 parts (weight) of polyester acrylate, under the stirring condition of mixer speed > 600r / min, add 5 parts (weight) of epoxy acrylate, 20 parts (weight) of high-viscosity monofunctional polyurethane acrylate, 3 parts (weight) of acrylic monomer part (weight), 10 parts (weight) of photoinitiator, disperse at high speed, stir, until photoinitiator is all dissolved. Under the condition that the rotational speed of the mixer is less than 300r / min, 4 parts (by weight) of fillers and 16 parts (by weight) of yellow organic pigments are added. After the materials are mixed evenly, under the condition of the speed of the mixer > 600r / min, disperse at a high speed, fully wet the powder, and then use a three-roller to grind to a fineness of ≤ 6um to obtain the finished product.

Embodiment 2

[0054] Get 42 parts (weight) of polyester acrylate, under the stirring condition of mixer speed > 600r / min, add 5 parts (weight) of epoxy acrylate, 20 parts (weight) of high-viscosity monofunctional polyurethane acrylate, 3 parts (weight) of acrylic monomer part (weight), 10 parts (weight) of photoinitiator, disperse at high speed, stir, until photoinitiator is all dissolved. Under the speed of the mixer 600r / min, disperse at a high speed to fully wet the powder. Then use a three-roller to grind to a fineness of ≤6um to obtain the finished product.

Embodiment 3

[0056] Get 42 parts (weight) of polyester acrylate, under the stirring condition of mixer speed > 600r / min, add 5 parts (weight) of epoxy acrylate, 20 parts (weight) of high-viscosity monofunctional polyurethane acrylate, 3 parts (weight) of acrylic monomer part (weight), 10 parts (weight) of photoinitiator, disperse at high speed, stir, until photoinitiator is all dissolved. Under the speed of the mixer 600r / min, disperse at a high speed to fully wet the powder. Then use a three-roller to grind to a fineness of ≤6um to obtain the finished product.

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 to15 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 which meets the requirements of high-speed printing and complex molding processing of packaging printing, and meets the requirements of environmental protection and its application. 【Background technique】 [0002] At present, solvent-based inks are widely used in the printing industry, and the high-boiling-point solvents used contain certain benzene compounds. When the benzene compounds exceed the standard, they will pollute the surrounding environment and endanger people's health. With the rapid development of the packaging and printing industry, higher requirements are 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 trademarks because of its incomparable advantages over traditional solvent-based inks. ...
