Problems solved by technology

The traditional ink curing methods are heat curing and UV curing. The curing time is relatively long and the energy consumption is high. Especially for printed matter that requires double-sided printing, it is necessary to wait for the printed side to be completely cured before printing and curing the other side. Printing efficiency is very low

Embodiment 1

[0048] A LED-UV ink for high-speed double-sided printing, prepared from the following raw materials in parts by weight:

[0049]

[0050]

[0051] The preparation method comprises the following steps:

[0052] (1) Weigh the prepolymer, reactive diluent, photoinitiator, wax powder, filler, auxiliary agent, and pigment by weight and place them in the ink mixer for stirring to complete the wetting and preliminary dispersion of the solid components in the liquid components , get the ink;

[0053](2) Put the ink material obtained in step (1) into a three-roller grinder and grind it under light-shielding conditions until the fineness of the ink reaches below 10 μm to obtain the LED-UV for high-speed double-sided printing ink.

Embodiment 2

[0055] A LED-UV ink for high-speed double-sided printing, prepared from the following raw materials in parts by weight:

[0056]

[0057]

[0058] The preparation method is the same as in Example 1.

Embodiment 3

[0060] A LED-UV ink for high-speed double-sided printing, prepared from the following raw materials in parts by weight:

[0061]

[0062]

[0063] The preparation method is the same as in Example 1.

[0064] In embodiment 1-3, polyurethane acrylate adopts aliphatic polyurethane acrylate Laromer UA9033 (Germany BASF); Polyester acrylate adopts polyester acrylate Laromer LR 9004 (Germany BASF); Polytetrafluoroethylene wax powder adopts polytetrafluoroethylene Ethylene wax micropowder PTFE-0101 (Nanjing Tianshi New Material Technology Co., Ltd.); polyamide wax powder adopts micronized polyamide wax powder Crayvallac LV (France Arkema); ultrafine calcium carbonate adopts nano calcium carbonate (particle size 20nm, Shanghai Naiou Nano Technology Co., Ltd.); the wetting and dispersing agent adopts modified polyether wetting and dispersing agent TEGO Dispers 650 (Evonik Tego); the leveling agent adopts polyether modified polysiloxane leveling agent BYK -UV 3500 (Bick, Germany)...

Abstract

The invention discloses LED-UV ink for high-speed double-sided printing and a preparation method thereof. The LED-UV ink is prepared from the following raw materials: a prepolymer, a reactive diluent, a photoinitiator, a pigment, a filler, wax powder and an auxiliary agent. The prepared LED-UV ink can be rapidly cured in an LED-UV curing system, a cured ink film layer is high in glossiness and good in wear resistance, the ink does not contain volatile substances and is safe and environmentally friendly, and the printing efficiency and the printing quality are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to an LED-UV ink used for high-speed double-sided printing and a preparation method thereof. Background technique [0002] Ink is an important material for printing packaging materials. After ink is printed on the substrate in various ways, it needs to be cured to make it firmly adhere to the substrate. The traditional ink curing methods are heat curing and UV curing. The curing time is relatively long and the energy consumption is high. Especially for the printed matter that needs double-sided printing, it is necessary to wait for the printed side to be completely cured before printing and curing the other side. Printing efficiency is very low. [0003] Therefore, it is necessary to improve the ink so that it can achieve rapid curing under the condition of low energy consumption. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpos...
