Problems solved by technology

[0004] 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 ultraviolet curing printing ink for silk-screen printing. The ultraviolet curing printing ink is characterized by being prepared by the following raw material in parts by weight: 1 to 3 parts of organic pigment, 12 to 15 parts of trimethylolpropane triacrylate, 9 to 12 parts of 1,6-hexanediol diacrylate, 2 to 4 parts of magnesium aluminate spinel powder, 10 to 12 parts of dipropylene glycol diacrylate, 1 to 2 parts of trimethylolpropane, 1 to 2 parts of phenyl glycidyl ether, 6 to 9 parts of propylene glycol methyl ether acetate, 4 to 6 parts of 184 photoinitiator, 3 to 4 parts of an accelerant DM, 1 to 2 parts of a crosslinking agent TAC, 1 to 2 parts of cobalt naphthenate, 1 to 2 parts of zirconium fluoride and 4 to 5 parts of an additive. The ultraviolet curing printing ink improves the toughness of printing ink, enables the printing ink to be uniformly distributed, maintains the stability of the printing ink, has good toughness, guarantees good adhesive force of overprinted ink films, avoids defects of cracking and falling off of the ink films, is high in curing speed, saves energy consumption, and is relatively environmentally friendly.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet curing ink for screen printing and a preparation method thereof. Background technique [0002] Screen printing is to stretch silk fabrics, synthetic fabrics or wire mesh on the screen frame, and adopts the method for manual engraving paint film or photochemical plate-making to make screen printing forme. Modern screen printing technology is to use photosensitive materials to make screen printing plates by means of photographic plate making (so that the screen holes of the graphic part on the screen printing plate are through holes, and the screen holes of the non-graphic part are blocked. Live) Oil paintings, prints, posters, business cards, binding covers, commodity packaging, commodity signs, printing and dyeing textiles, glass and metal and other flat carriers. [0003] At present, in the screen printing process, the thickness of the ink film after sol...
