Problems solved by technology

However, the existing pigments have high foaming properties in water, and even if the amount of pigments added is increased, a large amount of foam will be generated, which will cause problems in the recovery system of the inkjet printer drainage tank
At the same time, it will also cause the pipeline of the ink circulator to be blocked

Abstract

The invention discloses edible ink for ink-jet printing on the surface of an eggshell, which comprises the following components in percentage by weight: 3-6% of edible pigment, 0.01-0.5% of hydroxypropyl cellulose, 0-20% of propanediol, 0.0001-0.1% of ink lubricant, 0.0001-0.05% of dispersant and the balance of water. The preparation method comprises the following steps: preparing 0.1-5wt% of hydroxypropyl cellulose water solution; preparing the ink lubricant having a polydimethylsiloxane-silicon dioxide ratio of (8.5:1.5)-(9:1); preparing an emulsion from the ink lubricant, the dispersant and the water; and preparing the product from the edible pigment, the propanediol, the hydroxypropyl cellulose water solution and the emulsion. Compared with the prior art, the ink disclosed by the invention is safe to eat and highly applicable to various ink-jet printers, and has the advantages of excellent visibility, water resistance, stability and the like for an eggshell.

Description

technical field [0001] The invention relates to an edible ink, in particular to an edible ink used for ink-jet printing on the surface of an eggshell and a preparation method thereof. Background technique [0002] Printing inks play a pivotal role in the printing and packaging industries. However, because traditional inks contain a large number of harmful ingredients, especially gasoline, benzene and its derivatives, kerosene, alcohols, etc. involved in the preparation and use of solvent-based inks, it has caused great harm to the health of front-line workers. threat. Especially when these inks are used for the printing of food and medicine, they will directly or indirectly pollute these items and endanger people's health. Edible inks are special inks, which not only have the general commonality of printing inks, but also are gradually widely used in the surface decoration of food, health care products and medicines, or the packaging and printing of such products because o...
