UV (Ultraviolet)-curing scrubbing-resisting printing ink composition and preparation method thereof

Abstract

The invention provides a UV (Ultraviolet)-curing scrubbing-resisting printing ink composition and a preparation method thereof. By adopting the UV-curing scrubbing-resisting printing ink composition, prepared printing ink can be jetted smoothly and a spraying nozzle is not blocked; a pattern is bright; a fluorinated monomer is added, so that a printed product has good scrubbing-resisting performance. The total composition relative to UV-curing scrubbing-resisting printing ink is prepared from 5 mass percent to 20 mass percent of UV color paste, 10 mass percent to 40 mass percent of a light-curing acrylate prepolymer, 50 mass percent to 80 mass percent of an active diluting agent, 3 mass percent to 10 mass percent of an additive and 2 mass percent to 5 mass percent of a photo-initiator. The method comprises the following steps: dissolving the light-curing acrylate prepolymer, the additive, the active diluting agent and the photo-initiator into a solvent to obtain a mixed solution; dispersing the UV color paste into the mixed solution, and stirring in a dark place to obtain a premix; transferring the premix into a high-speed dispersant, and stirring at a high speed until the grain diameter of pigment is less than 600nm; filtering and discharging to obtain the UV-curing printing ink composition.

Description

technical field [0001] The invention relates to the field of UV inks, in particular to a UV curing scrub-resistant ink composition and a preparation method thereof. Background technique [0002] Commonly used inks are solvent inks, water-based inks and UV inks. Solvent inks will emit organic volatiles during the printing process, which may cause potential harm to the working environment and users; water-based inks will have poor printing results due to the long drying time; while UV inks generally only need 1 / 10 second. It is completely fixed on the surface of the substrate, and the UV light can not only cure the surface of the UV ink, but also penetrate deep into the ink to stimulate the further curing of the deep ink film. [0003] Compared with traditional ink, UV ink has the following advantages: First, its photopolymerization and curing are more thorough, and it does not generate any solvent-based pollutants, which is more environmentally friendly. In addition, the UV...

Problems solved by technology

[0004] However, the UV inks on the market still need to be improved and optimized. Generally speaking, the UV ink is cured before it can fully penetrate, and the film layer is mainly on the surface of the printing material. The adhesion between the ink and the printing material needs to be Less than solvent ink, etc., the adhesion to some printing materials needs to be improved

Therefore, although the research and development of UV ink has achieved good results, it has good scratch resistance for printed products, and good flexible UV curable ink needs further research.
