Description

一种安全环保紫外光固化油墨及其制备方法A kind of safe and environment-friendly ultraviolet curing ink and preparation method thereof

技术领域 technical field

本发明涉及一种油墨及其制备方法,特别是一种安全环保紫外光固化油墨及其制备方法。 The invention relates to an ink and a preparation method thereof, in particular to a safe and environment-friendly ultraviolet light curing ink and a preparation method thereof.

背景技术 Background technique

紫外光固化(UV)油墨是指在紫外线照射下,利用不同波长和能量的紫外光使油墨成膜和干燥的油墨。利用不同紫外光谱,可产生不同能量,将不同油墨连结料中的单体聚合成聚合物,所以UV油墨的色膜具有良好的机械和化学性能。UV油墨的主要优点有:(1)不用溶剂;(2)干燥速度快,耗能少;(3)光泽好,色彩鲜艳;(4)耐水、耐溶剂,耐磨性能好。UV油墨中光引发剂是一种易受光激发的化合物,在吸收光照后激发成自由基,能量转移给感光性分子或光交联剂,使UV墨发生光固化反应。目前UV墨已成为一种较成熟的油墨技术,其污染物排放几乎为零。紫外光固化油墨由于体系中不含溶剂,具有高效、适应性广、经济、节能、环境友好,成为具有广阔发展前景的新型油墨。 Ultraviolet curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to form a film and dry the ink under ultraviolet radiation. Using different ultraviolet spectra, different energies can be generated to polymerize monomers in different ink binders into polymers, so the color film of UV ink has good mechanical and chemical properties. The main advantages of UV ink are: (1) No solvent is used; (2) Fast drying speed and less energy consumption; (3) Good gloss and bright colors; (4) Water resistance, solvent resistance, and good wear resistance. The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into a free radical, and the energy is transferred to the photosensitive molecule or photocrosslinking agent, so that the UV ink undergoes a photocuring reaction. At present, UV ink has become a relatively mature ink technology, and its pollutant discharge is almost zero. Since the UV-curable ink does not contain solvents in the system, it has the advantages of high efficiency, wide adaptability, economy, energy saving, and environmental friendliness, and has become a new type of ink with broad development prospects.
