Problems solved by technology

However, the polymer resin binder in the water-based ink cannot provide high enough viscosity, so that the adaptability of the water-based ink to the substrate is not as good as that of the oil-based ink, and the adhesion is poor. To increase the adhesion, a layer of UV primer must be added to the substrate in advance. Oil or surface treatment such as frosting, corona, surface oxidation, etc., consumes a certain amount of time, manpower, material resources and financial resources

Abstract

The invention relates to an aqueous UV (ultraviolet) printing ink dispersed by utilizing a vermiculate micelle system and a preparation method thereof. According to the preparation method, a vermiculate micelle phase is formed in an aqueous solution by using a composite surfactant composed of a polymerizable type cationic surfactant and organic acids / organic salts, and various printing ink components (solid pigment, an aqueous ultraviolet light initiator, and various functional additives and a small amount of monomers) are encapsulated in the vermiculate micelle phase; and the aqueous UV printing ink with viscoelasticity is prepared by the steps of ultrasonic dispersion, centrifugal filtration and the like. According to the invention, an organic solvent is prevented from being used, so that the aqueous printing ink is environmentally-friendly; the aqueous printing ink has UV initiating activity, can be rapidly crosslinked and solidified on the surface of a printing stock, and embodiesgood water tolerance and abrasive resistance; and the vermiculate micelle in the system endows the printing ink with changeable fluid properties at different temperatures, and enables the printing ink to have better leveling property at high temperature and higher adhesion at low temperature, thus the aqueous printing ink is suitable for high-speed printing on various printing stocks such as plastic, metal and the like and has excellent gloss and color reproducibility.
