Printing ink for label

Abstract

The invention provides printing ink for a label. The printing ink is prepared from the following components in parts by weight: 60 to 80 parts of borax, 30 to 40 parts of kerosene, 15 to 20 parts of potassium sorbate, 8 to 13 parts of anti-seepage agent, 15 to 20 parts of anhydrous sodium carbonate, and 600 to 800 parts of boiled water. A preparation method of the printing ink for the label comprises the following steps of adding the borax into the boiled water, dissolving, and cooling to room temperature; then adding the potassium sorbate, the anti-seepage agent and the anhydrous sodium carbonate, uniformly stirring, and avoiding floating at the liquid level or settling at the bottom; and finally, adding the kerosene, and sufficiently mixing, so as to obtain the printing ink for the label. The printing ink disclosed by the invention has the advantages that the borax is matched with the kerosene, the drying of the printing ink is accelerated, the printing surface of the label is cleaned, and the potassium sorbate can realize the corrosion protection function.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a printing ink for labels. Background technique [0002] Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. At present, more than 95% of the printing of domestic plastic flexible packaging is by gravure printing. Commonly used printing inks are generally made of chlorinated polymers. In the process of production and use, strong aromatic solvents are needed to dissolve and adjust the viscosity of the ink, which is irritating, not environmentally friendly, and the drying speed of the ink is too slow. During the printing process, it is easy to cau...

Problems solved by technology

Commonly used printing inks are generally made of chlorinated polymers. In the process of production and use, strong aromatic solvents are needed to dissolve and adjust the viscosity of the ink, which is irritating, not environmentally friendly, and the drying speed of the ink is too slow. During the printing process, it is easy to cause smudges on the back, uneven printing, deinking, etc., which seriously affect the printing quality
