Abstract

The invention discloses an ultraviolet light cured printing ink with good adhesive attraction and toughness. The printing ink is characterized by comprising the raw materials in parts by weight: 1-3 parts of organic pigment, 1-2 parts of nonandioic acid, 5-8 parts of 1,6 hexanediol, 1-2 parts of sebacic acid, 1-3 parts of vermiculite powder, 3-4 parts of graphene, 45-50 parts of polyester acrylate, 20-25 parts of methacrylic ester, 1-2 parts of morpholine, 1-2 parts of an accelerating agent DTDM, 5-9 parts of a 2959 photoinitiator, 1-2 parts of diethanol amine, 10-12 parts of trimethylolpropane triacrylate, 6-9 parts of acrylic acid ethyl ester, 1-2 parts of propanediol sebacate polyester, 1-2 parts of sodium fluosilicate and 4-5 parts of an additive. The additive improves the toughness of the printing ink, enables the printing ink to be dispersed uniformly, and maintains the stability of the printing ink. The printing ink can improve the solidification film flexibility while ensuring the good adhesive attraction of overprinted ink films, and improves the product quality.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet curable ink with excellent adhesion and toughness and a preparation method thereof. Background technique [0002] Ultraviolet curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to form a film and dry the ink under ultraviolet radiation. Using different ultraviolet spectra, different energies can be generated to polymerize monomers in different ink binders into polymers, so the color film of UV ink has good mechanical and chemical properties. The main advantages of UV ink are: (1) No solvent is used; (2) Fast drying speed and less energy consumption; (3) Good gloss and bright colors; (4) Water resistance, solvent resistance, and good wear resistance. The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into a free radical, and the energy is transfer...
