A kind of ultraviolet curing ink with antistatic effect and preparation method thereof

Abstract

The invention discloses an ultraviolet curing printing ink with an anti-static effect. The ultraviolet curing printing ink with the anti-static effect is characterized by comprising the following raw materials in parts by weight: 1-3 part(s) of an organic pigment, 12-15 parts of methyl methacrylate, 3-5 parts of diaminodiphenyl-methane, 20-24 parts of melamine formaldehyde resin, 10-12 parts of E-12 epoxy resin, 2-3 parts of polytetrafluoroethylene, 1-2 part(s) of diatomaceous earth, 2-4 parts of calcined pottery clay powder, 3-4 parts of citric acid, 1-2 part(s) of polyacrylonitrile microspheres, 1-2 part(s) of glycidol butyl ether, 3-4 parts of triethylene glycol, 1-2 part(s) of polyving akohol, 1-2 part(s) of an antioxidant DSTP, 5-8 parts of 184 photoinitiator, 1.3-1.5 parts of an accelerant D and 4-5 parts of auxiliaries. According to the invention, antistatic agents such as methyl methacrylate are added in the formulation of the ultraviolet curing printing ink, so that the ultraviolet curing printing ink can be used for absorbing static charge on the surfaces of materials better so as to achieve the anti-static effect, in addition, the processing and treatment are simple and convenient, and the physical and chemical property of base material is not influenced.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet curable ink with antistatic effect 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 transferred to the phot...

Problems solved by technology

In order to reduce the harm caused by static electricity, at present, people usually add pigments and fillers to UV-curable inks to suppress the generation of static charges and promote the leakage of static charges, thereby reducing the surface resistance of film-forming materials to a certain extent and enhancing The antistatic performance of the coating film, however, due to the structure of the coating material itself and the pigments and fillers are generally small molecules, the antistatic effect produced by this method is not very ideal. How to develop a good antistatic effect and antistatic Long-lasting antistatic additives, and used in UV-curable inks, are a problem for all those working in the UV-curable ink field
