Problems solved by technology

[0002] The curing method adopted by traditional plastic ink is thermal curing or self-drying, which has long curing time and high energy consumption, which reduces the efficiency of industrial production, and contains a large amount of solvent, which is highly irritating, pollutes the environment, harms workers, and is not conducive to environmental protection.
Traditional plastic inks have many problems that cannot meet the production process requirements due to curing. In actual production, stationery products often use some plastic materials that cannot withstand high temperatures, and due to high printing accuracy requirements, it is not acceptable for products to be baked due to temperature. Deformation caused by roasting

Abstract

The invention discloses ultraviolet-cured plastic printing ink which is prepared from the following ingredients in mass percent content: 10 to 15% of monomer, 30 to 50% of photosensitive resin, 3 to 8% of photoinitiator and 30 to 44% of powder. The monomer is a mixture of ethoxylated pentaerythritol tetraacrylate and trimethylolpropane triacrylate, and the photoinitiator is a mixture of benzophenone and isopropylthioxanthone. The ultraviolet-cured plastic printing ink disclosed by the invention has the characteristics of quick curing, excellent adhesion, no faultage and strong base material adaptability, has excellent adhesion with plastic cement of PP, PE, PVC, PMMA, PC, PAS, PET, ABS and the like which are common plastics in printing, avoids varieties of method of leaky white, overprint and the like in continuous printing, is especially suitable for being applied to plastic base materials of cosmetics industry and has excellent adhesion. Meanwhile, the invention further discloses a preparation method of the ultraviolet-cured plastic printing ink.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet-cured plastic ink and a preparation method thereof. Background technique [0002] The curing method adopted by traditional plastic ink is thermal curing or self-drying, which has long curing time and high energy consumption, which reduces the efficiency of industrial production, and contains a large amount of solvent, which is highly irritating, pollutes the environment, harms workers, and is not conducive to environmental protection. . Traditional plastic inks have many problems that cannot meet the production process requirements due to curing. In actual production, stationery products often use some plastic materials that cannot withstand high temperatures, and due to high printing accuracy requirements, it is not acceptable for products to be baked due to temperature. Baking produces deformation. [0003] UV curing technology has the advantages of ec...
