Abstract

The invention belongs to the technical field of preparation of photocuring silk-screen printing ink, and particularly relates to printing ink as well as a preparation method and application thereof. The ink comprises aliphatic polyurethane acrylate, modified epoxy acrylate, coated silver paste and/or coated aluminum paste, a reactive diluent, a photoinitiator, a co-initiator and a polymerization inhibitor, wherein the aliphatic polyurethane acrylate is difunctional polyether polyol polyurethane acrylate, and the molecular weight of the aliphatic polyurethane acrylate is 3000 to 8000. The ink provided by the invention does not contain volatile solvents, is odorless, does not discharge VOC (volatile organic compounds), and is environment-friendly. According to the ink, an ink layer obtained through the synergistic effect of all the components has certain ductility, can automatically fall back during scraping and cannot form fragment powder to fall off, and the scraping difficulty cannot be increased along with the increase of storage time; and the ink is high in curing speed and can be deeply cured, and the problem that part of ink is not cured does not exist.

Description

technical field [0001] The invention belongs to the technical field of photocurable screen printing ink preparation, and in particular relates to an ink and its preparation method and application. Background technique [0002] Scratch silver ink refers to the layer of silver-gray ink that is easily scratched off for covering passwords (deduction areas) such as lottery tickets, phone cards, and tax invoices with prizes. Traditional solvent-based scratch-off silver inks have been in the market for decades, and the technology is quite mature. The process of this type of ink is that the printed matter is generally a variety of soft or hard paper. The ink is printed on the paper that needs to be protected and hidden information through silk screen printing, offset printing, etc., and then baked or self-dried. Surface dry and fully cured, and then packaged into finished products. [0003] At present, with the development of social economy and the improvement of people's awarenes...
