Description

紫外光固化印刷油墨 UV-curable printing inks

技术领域 FIELD

本发明涉及到一种印刷油墨,尤其涉及一种通过紫外光固化方式干燥的丝网印刷油墨。 The present invention relates to a printing ink, in particular, it relates to a UV curable screen printing ink drying embodiment.

背景技术 Background technique

紫外光固化印刷丝网油墨是通过丝网印刷的方式印到基材上,并通过紫外线固化方式完成固化反应,形成最终的产品。 UV-curable screen printing ink is printed by a screen printing method onto a substrate, and to complete the curing reaction of the ultraviolet curable embodiment, to form the final product. 与传统的挥发干燥或氧化干燥的印刷油墨相比,紫外光固化印刷油墨不含挥发性有机溶剂(VOC),因此避免了对水和空气的污染。 Compared with the conventional evaporation or drying of oxidatively drying printing inks, UV-curable printing inks free of volatile organic solvents (the VOC), thus avoiding pollution of water and air.

紫外光固化油墨不仅具有环保的优点,而且具有固化速度快的特点,可大幅度提高生产效率,适应了现代高速印刷的要求。 UV-curable inks not only has environmental advantages, but also has the characteristics of high curing rate, can greatly improve the production efficiency, adapted to the requirements of modern high-speed printing.

丝网印刷是从通过刮墨板挤压方式将油墨从印板孔中转移到承印物上的一种印刷方式。 Screen printing ink is transferred from the plate by pressing the squeegee from the printing plate wells manner to a printed substrate on the way. 印版基本上是以柔软的丝网和感光性乳胶所构成,印刷工具多为聚氨酯橡胶刮板。 The plate is substantially flexible mesh and a photosensitive emulsion composed, mostly for printing tools urethane rubber blade. 丝网印刷不仅可用于平面印刷,而且也可用于曲面印刷,因此在塑料容器,玻璃制品等上面也可进行印刷。 Screen printing can be used not only print, but also for the printing surface, so the above plastic container, glass, etc. may also be printed. 丝网印刷作为一种灵活的印刷方式,广泛应用于各种工艺品,陶瓷,木制品、电子、机械等领域。 Screen printing as a flexible printing, widely used in various products, ceramic, wood products, electronic, machinery and other fields.

但是紫外光固化油墨本身也存在一些缺点,如树脂的耐久性较差,高固化速度的同时也带来柔韧性较差等问题。 However, UV-curable ink itself also has some shortcomings, such as poor durability of the resin, while the high curing speed also brings problems such as poor flexibility. 专利CN1387555A公开了一种紫外光固化涂料组合物及其制造和应用方法,具有改善的外观和使用性能,但是对耐候性能没有明确的改进方法。 Patent No. CN1387555A discloses a UV curable coating composition and its manufacturing method and application, having improved appearance and performance, but there is no clear method to improve weather resistance. 专利CN1092458C公开了一种不变黄的紫外光固化涂料,该涂料主要用于罩光使用,没有针对颜料的褪色提出明确的解决方法。 Patent CN1092458C discloses a yellowing UV-curable coatings, the coating is mainly used for the varnish, no clear solution for the bleaching of pigments. 由于印刷油墨与涂料相比,对着色要求和使用性能要求较大区别,因此这些方法不能完全解决紫外光固化印刷油墨的耐久性问题。 Since compared with the printing ink coating, coloring and requires very different performance requirements, and therefore these methods can not completely solve the problem of the durability of UV-curable printing inks.
