[0003] The test found that for a substrate that needs to be overprinted more than 3 times to reflect its unique printing effect, if the existing ink is used for printing, after the ink is printed on the surface of the substrate and cured, when the substrate is squeezed or bent, the ink will disappear. The surface of the film usually has obvious cracks and falls off, which affects the product quality

Abstract
The invention discloses a UV-curing printing ink with high flexibility and a preparation method thereof. The UV-curing printing ink is characterized by being prepared from the following raw materials in parts by weight: 1-3 parts of an organic pigment, 30-35 parts of urethane acrylate, 30-35 parts of hydroxyethyl methylacrylate, 14-18 parts of isobornyl methacrylate, 10-12 parts of 2-hydroxyl acrylic resin, 6-9 parts of 1-hydroxycyclohexyl phenyl ketone, 1-2 parts of rose essential oil, 4-5 parts of coumarone, 1-2 parts of an accelerator DM, 3-4 parts of octadecyl trimethyl ammonium chloride, and 4-5 parts of an assistant. The assistant improves the flexibility of printing ink, enables the printing ink to be uniformly dispersed, and maintains the stability of the printing ink. A favorable adhesive force of an overprint ink film is ensured while the flexibility of the cured film is improved, and the quality of the product is improved.
Description
technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet curable ink with good toughness and a preparation method thereof. Background technique [0002] At present, in the screen printing process, the thickness of the ink film after solidification is thicker than that of other printing methods. Generally, the thickness of the ink film for a single printing is 20-40 μm. In order to ensure good ink on the surface of the substrate Adhesion, the total thickness of the ink overprinted on the surface of the substrate should not exceed 100 μm, that is, the ink can generally be overprinted up to 3 times on the substrate. [0003] The test found that for a substrate that needs to be overprinted more than 3 times to reflect its unique printing effect, if the existing ink is used for printing, after the ink is printed on the surface of the substrate and cured, when the substrate is squeezed or bent, the ink will disappear....
