UV curable jet printing ink and preparation method thereof

The invention provides a UV curable jet printing ink and a preparation method thereof. The ink is UV curable, has a 100% solid content, is free of VOC emission in the production and use process, and is environment-friendly. Because of the adoption of inkjet printing, the ink provided by the invention solves the problem that the traditional silk screen character ink cannot produce pipeline code, isfast and efficient, and the character is clearer. By weight, the UV curable jet printing ink includes 60-90 parts of an acrylic monomer, 5-25 parts of titanium dioxide powder and 3-10 parts of a photoinitiator; and the acrylic monomer consists of a trifunctional acrylic monomer, a bifunctional acrylic monomer, and a monofunctional acrylic monomer. The UV curable jet printing ink provided by the invention has low viscosity and fast curing speed. 本发明提供了种UV固化喷印油墨及其制备方法，该油墨UV固化，100％固含量，生产及使用过程中不产生任何VOC排放，环境友好。因为可以采用喷墨打印，解决了传统丝印字符油墨无法生产流水码的问题，快速高效且字符更清晰。按重量份记，包括丙烯酸单体60-90份、钛白粉5-25份、光引发剂3-10份；所述丙烯酸单体包括三官能团丙烯酸单体、双官能团丙烯酸单体、单
