Printing ink for plastic film

Abstract

The invention discloses printing ink for plastic film. The printing ink is manufactured by the following raw materials in parts by weight: 10-15 parts of waterborne polyurethane resin, 5-6 parts of dimethyl phthalate, 1-2 parts of linseed oil, 2-3 parts of sweet potato powder, 1-2 parts of silicon carbide, 1-2 parts of nanometer bentonite, 1-3 parts of phthalocyanine blue, 1-2 parts of nanometer zinc oxide, 2-5 parts of 2,4-dihydroxy benzoic acid, 2-4 parts of silicone, 3-5 parts of urea, 1-3 parts of terbium nitrate, 2-3 parts of starch sodium ocentyl succinic anhydride, 8-10 parts of sec-butyl acetate, 0.5-1 part of fluorescent powder, 0.5-1 part of microcrystalline wax, 1-2 parts of europium trifluoroacetyl acetone, 1-3 parts of tetrahydrofuran, 10-12 parts of trimethylolpropane triacrylate, 8-10 parts of dipentaerythritol hexaacrylate, 1-1.5 parts of aluminum nitride, 1-2 parts of dibutyltin dilaurate, 1-2 parts of tert-butyl peroxypivalate and 4-5 parts of assistant. Due to the fact that organic substances and inorganic substances are effectively combined, the prepared printing ink is good in fluidity and viscosity, attractive and limpid in color and very good in development prospect.

Description

technical field

[0001] The invention belongs to the technical field of coatings, in particular to a printing ink for plastic films. Background technique

[0002] Ink is a paste-like adhesive with certain fluidity. Viscosity, flexion value, thixotropy, fluidity, dryness, etc. all determine the performance of the ink. Among them, the viscosity has an important relationship with the ink transfer during the printing process, the properties and structure of the paper. If the viscosity is too large, the printing process will The transfer of the ink is not easy to be uniform, and the phenomenon of roughening the paper occurs, which makes the layout bloom; if the viscosity is too small, the ink is easy to emulsify and get dirty, which affects the quality of the printed matter; the yield value is related to the structure of the ink, and the yield value is too large. The fluidity will become poor and it will not be easy to open; if the yield value is too small, the dots will be easil...
