Problems solved by technology

[0002] UV-curable iron printing inks are generally cured by UV high-pressure mercury lamps, which have defects such as high energy consumption, high heat generation, short service life, unfavorable environmental protection, and poor impact resistance of printed products. It is difficult for the ink to dry under the LED-UV light source, and the ink film has the problem of poor stamping resistance, so it is necessary to develop a stamping-resistant iron offset printing ink that can dry quickly under the LED-UV light source

Abstract

The invention discloses punching-resistant LED-UV metal printing offset ink and relates to the technical field of metal printing offset ink. The punching-resistant LED-UV metal printing offset ink is prepared from ingredients in percentage by mass: 45 to 60% of UV resin, 5 to 20% of reactive diluents, 3 to 5% of dibenzoyl and derivative of the dibenzoyl, 4 to 4.5% of BAPO, 3 to 3.5% of alpha-hydroxyketone derivative, 2 to 2.5% of alpha-aminoketone derivative, 5 to 8% of auxiliary agent, 12 to 18% of pigment and 0.3 to 0.5% of graphene. The ink disclosed by the invention is cured to form an ink film, the ink film has good adhesion and flexibility, cross-cut test can reach 5B, a post-print processing requirement can be met, and the ink film cannot crack under 50Nm punching; furthermore, after the ink is printed to a plain sheet base material and irradiated by a low-energy LED-UV lamp, an accumulated light quantity value can reach 15mJ / cm<2>, instant full curing can be achieved, and a drying speed is quick.

Description

Technical field [0001] The invention relates to the technical field of iron printing offset printing inks, in particular to a stamping resistant LED-UV iron printing offset printing ink. Background technique [0002] UV-curable iron-printing offset printing inks are generally cured by UV high-pressure mercury lamps, which have the disadvantages of high energy consumption, large heat generation, short service life, not conducive to environmental protection, and poor impact resistance of printed products, while ordinary UV-curing iron-printing offset printing The ink is difficult to dry under the LED-UV light source, and the ink film has the problem of poor stamping resistance. Therefore, it is necessary to develop a stamping-resistant iron printing offset printing ink that can dry quickly under the LED-UV light source. Summary of the invention [0003] To solve the above technical problems, the present invention provides a stamping resistant LED-UV iron printing offset printing ink...
