Abstract

The invention discloses UV curing ink for an aluminum plate and a preparation method of the UV curing ink, belonging to the technical field of UV curing ink. The UV curing ink comprises, in parts by weight, 55 to 70 parts of unsaturated resin, 20 to 30 parts of acrylate monomers, 1 to 10 parts of a photoinitiator, 5 to 10 parts of a pigment and 1 to 5 parts of an auxiliary agent. According to theinvention, the UV curing ink with excellent comprehensive performance is obtained by adjusting the types and proportions of the soft and hard acrylate monomers. The ink is environment-friendly and non-toxic and has a high curing rate; epoxy groups in epoxy resin have excellent adhesive force to aluminum products; the ink is excellent in water resistance, solvent resistance, heat resistance, weather resistance and wear resistance after being cured; and the UV curing ink prepared in the invention can be attached to the surface of a metal product, and is especially suitable for roller coating tothe surface of a steel product.

Description

technical field [0001] The invention belongs to the technical field of UV curable inks, in particular to a UV curable ink for aluminum plates and a preparation method thereof. Background technique [0002] UV ink is composed of photosensitive resin, reactive diluent monomer, pigment, initiator and various additives. The solid content of UV ink is 100%, and no organic solvent is used as a solvent. When curing, ultraviolet light with specific wavelength and energy is used to make the ink chain-extended, cross-linked and dried and cured within a few seconds, producing very little volatile organic compounds, which is environmentally friendly. A type of ink. UV ink only uses ultraviolet light to cure the ink, which greatly saves energy. [0003] If the UV ink only uses polyacrylate as the ink binder, there are many shortcomings, such as hot stickiness, cold brittleness, poor water and weather resistance, etc. The epoxy group in epoxy acrylate has excellent adhesion to the meta...
