Water-based luminous ink and preparation method thereof

Abstract

The invention provides a water-based luminous ink and a preparation method thereof. The water-based luminous ink contains 8-25% of pigment, 22-36% of water soluble acrylic resin, 4-18% of ethanol, 4-15% of triethylamine, 5-18% of rare earth luminescent material, 0.01-0.05% of metal salt, 12-26% of water and 1-6% of auxiliaries according to the weight percentage. The water-based luminous ink provided by the invention has the advantages that a printing product printed by using the ink has long lasting phosphorescent performance because the rare earth luminescent material is added to the water-based ink; and therefore, a reader or a user can also see a product with a label printed by the ink under a dark environment condition without light sources.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a water-based luminous ink and a preparation method thereof. Background technique [0002] Water-based ink is referred to as ink for short. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. Water-based ink is especially suitable for packaging and printing products that require strict hygienic conditions such as tobacco, alcohol, food, beverages and medicines. When people read the packaging labels of cigarettes, alcohol, food, beverages and medicines, they all need to be carried out under light conditions. However, when people travel in the field, work underground, and encounter darkness, no sunlight and light in their daily lives, even if they have these items on hand, they cannot use them normally.
