Abstract

The invention discloses fragrant ink and a preparation method thereof, wherein the fragrant ink comprises a thinner, a diluent and fragrant powder, the thinner comprises acrylic ester substances, acryloylmorpholine, 2-hydroxy-2-methyl-1- [4- (2-hydroxyethoxy) phenyl ] -1-propanone and 2,4, 6-trimethylbenzoyl-di (p-tolyl) phosphine oxide, the diluent comprises acrylic ester substances, an ink adhesive, phosphoric ester substances and p-hydroxyanisole, and the acrylic ester substances in the thinner comprise acrylic ester substances in the diluent. According to the fragrant ink, the thinner and the diluent share acrylic ester substances as basic components, so that two types of key auxiliary agents can be better fused in an ink system, rejection reaction among different components is reduced, the problems of layering, precipitation, uneven gloss and the like are avoided, the stability of the whole ink is ensured, and meanwhile, the component debugging difficulty in the production process is also simplified.

Description

Fragrant ink and preparation method thereof Technical Field The invention belongs to the technical field of ink, and particularly relates to fragrant ink and a preparation method of the fragrant ink. Background In the current label printing market, although the printing process is rich in types, and various modes such as relief printing, intaglio printing, flexography printing, silk screen printing and digital printing are covered, the expression requirements of various patterns, colors and materials can be met to a certain extent, and however, in an application scene combining functionality and sensory experience, a significant technical blank still exists. Especially, under the requirements that customers hope that the labels not only have visual appeal, but also can enhance product experience and improve brand memory through smell, the existing common ink formula is difficult to realize stable and durable fragrance attaching and releasing effects. Meanwhile, conventional inks tend to be prone to sacrificing their base properties when they are required to achieve special effects. For label printing, the leveling property of the ink directly affects the uniformity and surface gloss of the printed pattern, while the stability of the ink is related to the consistency of quality of the storage, printing process and finished label, including viscosity stability, dispersibility, and anti-settling property. The existing attempts of adding essence or aroma substances often cause the problems of poor leveling property, changed drying property, reduced printability of the ink, or over-fast volatilization of aroma, uneven distribution, unstable property during storage and the like due to poor compatibility of the aroma components and an ink system. Therefore, in the field of label printing, the conventional fragrant ink is unstable in formula, and has uneven printing and uneven effect, and poor leveling property. It is an important and urgent task to develop an ink formulation which can not only permanently emit a suitable fragrance, but also maintain excellent printability, store stably and not affect the physicochemical properties of the printed product.
