Definitions

  • the present invention relates to the field of inks, and relates to an environmentally friendly ink for improving image resolution, and more particularly to an environmentally friendly ink for direct inkjet printing which can be used for inkjet printing direct plate making technology (CTP) and a method for preparing the same.
  • CTP direct plate making technology
  • CTP technology which represents the development direction of international advanced printing plate making, omits the traditional photographic imaging process and simplifies the plate making process, but still has not got rid of the idea of photographic chemical imaging. There is still a problem of chemical waste pollution in post-treatment.
  • Ink is used as the core material of inkjet printing direct plate making technology.
  • the inkjet inks reported so far include water-soluble ink solution, thermosetting ink, ultraviolet (UV) curing ink, etc., but the printing yield of the printing plate of the above ink is printed. (force) in 1 to 20,000 copies, the image quality and resolution of printed matter is low, so the development of an environmentally friendly, high-resolution ink is the key to determining the direction of CTP printing.
  • Weak solvent inks are popular solvent inks in recent years. The main reason is that weak solvent inks are not only very low in taste, but also have fine ink particles. The inkjet printing is beautiful. The most important feature of weak solvent inks is environmental friendliness, mainly due to the reduction of volatiles (V0C) and the elimination of many toxic organic solvents (such as cyclohexanone, butanone, etc.) in weak solvent inks. The production workshop no longer requires ventilation. Weak solvent inks are very popular in developed countries, and traditional solvent inks have barely found a market in Europe and the United States.
  • the ink-jet printed images of water-based inks are not easy to dry and absorbed by the media, making them mainly used for paper and Various types of fibers (cloth) are used as substrates and coated media.
  • Screens usually made of aqueous ink are mainly used indoors because of poor weather resistance.
  • the invention combines water and a specific weak solvent as a solvent of the ink, further reduces the toxicity caused by the weak solvent in the ink, and combines the precision and the outdoor weather resistance to prepare an ink with low cost and high environmental performance.

  • the invention utilizes the high surface energy of the water system, and ensures that the ink system mixed with the weak solvent forms a small spray point and uniform shape during the inkjet printing process (the high surface tension of the ink promotes the droplets during the ink ejection process).

Description

用于喷墨直接制版的墨水及其制备方法
技术领域
本发明属于墨水领域，涉及提高图像分辨率的环保型墨水， 更具体涉及可用 于喷墨打印直接制版技术（CTP) 的喷墨打印直接制版的环保型墨水及其制备方 法。 背景技术
近年来代表国际先进印刷制版发展方向的 CTP 技术省略了传统的感光成像 过程， 简化了制版工序， 但仍未摆脱感光化学成像的思路， 后处理仍存在化学废 液污染问题。随着国际上很多强制性环保标准的出台， 环保型直接制版技术的研 究已成为世界印刷前沿领域新的热点。墨水作为喷墨打印直接制版技术的核心材 料， 目前报道的喷墨墨水包括水溶性墨水溶液、 热固油墨、 紫外光 (UV)固化油墨 等， 但上述墨水所制印版的印刷品的耐印量（力）在 1〜2万份， 印刷品的成像 质量和分辨率低， 因此发展一种环保、高分辨率的墨水是决定 CTP印刷制版方向 的关键。
弱溶剂墨水是近年来很受欢迎的溶剂墨水，主要原因是弱溶剂墨水不但味道 很低而且墨水颗粒很细， 喷墨打印的画面精美。弱溶剂墨水的最大特点是对环境 的友好性， 主要体现在可挥发物 （V0C ) 的减少和不再采用许多有毒害的有机溶 剂 （比如环己酮、 丁酮等溶剂）， 在弱溶剂墨水的生产车间不再需要通风装置。 弱溶剂墨水在发达国家很受欢迎， 传统溶剂墨水在欧洲和美国几乎找不到市场。 弱溶剂墨水已成为墨水行业发展的必然趋势 [戴斌， 乔旭， 丙二醇醚酯类溶剂的 生产及发展， 安徽化工， 2007， 33， 3， 4-6. ]。 弱溶剂墨水介于水性和溶剂型墨 水之间， 兼顾两者的优点， 具有环保、 高精度和户外耐侯性。 但是由于弱溶剂墨 水的主要成分： 二元醇醚酯类溶剂的生产工艺复杂， 生产流程长， 导致此类溶剂 的市场供应较少， 成本相对较高。 水性墨水的主要特点是成本低廉、 没有污染， 印刷品色彩鲜艳，但是因为其主要组分水的挥发速度慢， 由水性墨水喷墨打印的 画面不易干燥和被介质吸收， 使其主要应用于纸张以及各种纤维类 (布)为底材、 有涂层的介质上。 通常由水性墨水制作的画面因为耐侯性差而主要应用在户内。 本发明通过水与特定弱溶剂混合作为墨水的溶剂，进一步降低墨水中弱溶剂带来 的毒性， 并兼顾精度和户外耐候性， 制备低成本、 高环保性能的墨水。 发明内容
本发明的目的之一在于克服现有喷墨 CTP方法中的缺陷， 解决限制喷墨 CTP 大力发展和应用的问题，从而提供一种用于喷墨打印直接制版技术的喷墨打印直 接制版的环保型墨水， 使用该墨水在铝版基表面上打印， 可进行制版， 制得的印 版具有良好的耐印力和图像分辨率。
本发明的目的之二在于提供用于喷墨打印直接制版的环保型墨水的制备方 法。
用于喷墨打印制备印版的基底一 -铝版基具有高比表面能， 无机溶液和有机 溶液均能在其表面有很好的铺展和浸润，因此一般的喷墨墨水打印到铝版基表面 上形成图文时墨水扩散严重， 图像分辨率相对较低。本发明利用水体系的高表面 能， 能确保水与弱溶剂混合的墨水体系在喷墨打印过程中形成的喷射墨点小， 形 状均一（墨水的表面张力高会促进墨水喷射过程中的液滴形成与形状均一）；同时 利用弱溶剂的挥发和高精度性能，有效降低墨水在铝版基的高比表面能表面上的 扩散， 提高图像分辨率。
本发明的用于喷墨打印直接制版的环保型墨水是由可交联树脂及混合溶剂 制备得到的，将该墨水通过喷墨打印机打印在铝版基表面， 形成打印图像并获得 喷墨打印直接制备的印版， 热固化后形成高分辨率图像， 可直接上机印刷， 节省 了后处理过程， 获得了高质量喷墨打印印版。
本发明的用于喷墨打印直接制版并能提高图像分辨率的环保型墨水，以墨水 的总量为基准， 以质量百分比计， 该墨水的组分及含量为：
可交联树脂 5 %〜20 %
弱溶剂 5 %〜25 %
去离子水 55 %〜90 %
所述的可交联树脂选自市售的环氧树脂、酚醛树脂、聚乙烯醇树脂等所组成 的组中的至少一种。这些树脂存在热固化方式，只能在达到一定温度后才能固化， 不会出现在使用过程中墨水交联而造成喷墨打印机的打印喷头堵塞。
所述的弱溶剂选自丙二醇单甲醚、丙二醇单甲醚醋酸酯、丙二醇单甲醚丙酸 酯、 丙二醇单甲醚丁酸酯等所组成的组中的至少一种。
所述的去离子水的电导率优选为电导率低于 10 微西门子 /厘米。
本发明的墨水是通过多级过滤方法除去制备墨水混合液中不溶物和 /或杂质 后得到的滤液。
