Abstract

The invention discloses an ultraviolet-cured alkali washing resin as well as a preparation method thereof and the preparation method of a frosted ink, and belongs to the field of ink preparation. The method is characterized by comprising the following steps: mixing 0.5mol% of anhydride and 0.5mol% of hydroxyl acrylate to obtain a mixture; preacting; adding a polymerization inhibitor accounting for 0.1% to 0.2% of the mass of the mixture and a catalyst accounting for 0.2% of the mass of the mixture into the mixture; heating and reacting; and measuring an acid value, thus obtaining the ultraviolet-cured alkali washing resin. The ultraviolet-cured alkali washing resin has the advantages of high ultraviolet curing speed, good adhesive force, rapid alkali dissolution speed, small odor, light color and the like, and cannot generate turbid substances. The ultraviolet-cured alkali washing resin can react with a monomer, talcum powder, an aiding agent and a photosensitizer so as to prepare the ultraviolet-cured alkali washing frosted ink.

Description

technical field [0001] The invention relates to the field of ink material manufacturing, in particular to an ultraviolet light-curable alkali cleaning resin, a preparation method thereof, and a preparation method of frosted ink. Background technique [0002] UV curing is the most widely used curing technology in radiation curing. UV curing coating is an energy-saving and environment-friendly coating developed by Germany in the late 1960s. UV curing coatings have five characteristics: environmental friendliness, economy, high efficiency, energy saving and wide adaptability. It has various forms such as liquid type, powder type, and water-dispersed type. It is widely used in the coating of substrates such as paper, wood, plastic, and metal. It is also a research hotspot for the majority of paint workers. Oligomers are the matrix resins of UV curable coatings. The types of oligomers that are widely studied and used in UV curable coatings are mainly unsaturated polyesters, epo...
