Abstract

The invention relates to UV (Ultra Violet) offset printing carrier oil, connection UV offset printing gloss oil and preparation methods thereof. The offset printing ink comprises UV offset printing carrier oil and connection UV offset printing gloss oil, wherein the UV offset printing carrier oil is prepared from a polyester acrylate oligomer, filling, a reactive diluent, a high-viscosity additive, and the like by firstly adding a dispersant and resin, grinding the filling to a qualified degree of fineness and then adding the active diluent, a photoinitiator and the high-viscosity additive to stir and disperse together at a high speed, the connection UV offset printing gloss oil is prepared from a high-functional urethane acrylate oligomer, a dual-functional urethane acrylate oligomer, a photoinitiator, a leveling agent, and the like by stirring at a high speed, filtering, and the like. The offset printing ink and the method enable a printed product to generate the special concentration effect so as to obtain various special surface printing effects.

Description

technical field [0001] The invention relates to the field of ink chemical industry, and mainly relates to a UV offset printing ink and a preparation method thereof. Background technique [0002] UV offset printing ink is a relatively new type of printing ink in recent years. It mainly changes the ink from liquid to solid in an instant under the irradiation of ultraviolet rays of a certain wavelength to complete the drying process. It is usually composed of fillers, oligomers, reactive diluents, photoinitiators and additives, and has the advantages of no volatile solvents, no odor, non-drying plate, strong water and solvent resistance, etc. [0003] In the UV offset printing process, users often put forward many unique requirements, such as water drop lotus leaf effect, frosted etching effect, embossed laser effect, etc. For these effects, the current UV offset printing ink cannot achieve the required effect, and the current There are relatively few manufacturers that produc...
