Problems solved by technology

Metal printing is basically carried out in the form of offset printing. Metal printing ink has the printing suitability and printing effect of offset printing ink. Due to the printing adaptability and printing effect of the non-permeable body of the metal plate, the existing metal printing ink It has the characteristics of resistance to mechanical processing, and its properties are characterized by high viscosity and low fluidity. However, this is very unfavorable to the transfer of ink during printing, so it is necessary to improve the printing adaptability of metal printing iron ink
[0003] The Chinese invention patent application with application number 201210128217.1 discloses a UV curable silk screen snowflake ink, including UV curable resin, photoinitiator, defoamer, Raw materials such as leveling agent, polymerization inhibitor and wax powder, UV-curable silk screen printing snowflake ink is a special process ink of crystallization and fission type. ” phenomenon, and the addition of wax powder to the ink can easily reduce the viscoelasticity of the ink and increase the plasticity of the ink, especially the fluidity and transferability of the ink. Poor adaptability, cannot be used as metal printing ink, the transferability of metal printing iron ink needs to be improved

Abstract

The invention relates to the technical field of ink, and in particular relates to an ultraviolet (UV) offset tin printing ink and a method for preparing the same. The UV offset tin printing ink consists of the following raw materials in parts by weight: 28-38 parts of urethane acrylate, 20-30 parts of polyester acrylate, 2-10 parts of 2-propenoic acid, 1, 1'-[(1-methyl-1, 2-ethanediyl) bis [oxy(methyl-2, 1-ethanediyl)]] ester (TPGDA), 5-12 parts of trimethyl propane triacrylate (TMPTA), 1-9 parts of hexanediol diacrylate (HDDA), 14-22 parts of pigment powder, 1-3 parts of dispersing agent, 0.2-1.2 parts of organic silicon defoamer, 1-4 parts of organic silicon flatting agent, 1-3 parts of photoinitiator and 0.2-1.5 parts of adhesion promoter. The UV offset tin printing ink has low adhesiveness, improved fluidity, good ink flexibility, good transfer printing performance and good adaptability to metal product printing.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a UV offset iron printing ink and a preparation method thereof. Background technique [0002] Since the introduction of German-made platform printing machines in my country in 1900, metal printing has started. Metal printing is mainly used in packaging containers to convey the information of the items in the packaging, and to increase the added value through the effect of color and packaging. Metal printing is basically carried out in the form of offset printing. Metal printing ink has the printing suitability and printing effect of offset printing ink. Due to the printing adaptability and printing effect of the non-permeable body of the metal plate, the existing metal printing ink It has the characteristics of resistance to mechanical processing, and its properties are characterized by high viscosity and low fluidity. However, this is very unfavorable to the transfer of ink during ...
