Problems solved by technology

[0003] Although water-based ink has obvious advantages in solving the problem of VOCs exceeding the standard, it also brings new challenges and problems to printing companies, that is, it is necessary to overturn the inherent thinking of solvent-based ink printing, find another way, and explore and study the printing suitability that matches water-based ink. This requires relevant enterprises to make adjustments and choices in terms of ink raw material selection, ink solvent ratio, printing plate parameters, printing equipment parameters, etc.

Abstract

The invention relates to environmentally-friendly water-based gravure ink and a preparation method thereof and belongs to the technical field of printing ink. The water-based gravure ink comprises, byweight, 84.6% to 85.9% of a main film-forming substance, 0.3% to 0.6% of a pigment, 13% to 15% of a filler and 0.1% to 0.5% of a lubricant. The water-based gravure ink is suitable for gravure printing, has good printing adaptability, high abrasion resistance and good gloss, utilizes a water-soluble resin as a solvent, has no odor, no toxicity and low VOC, has a solvent residue detection value farlower than the safety and health requirement index, and has environmental protection characteristics. The water-based ink utilizes raw materials in wide sources, has a low preparation cost, is easy to transport and store, has good stability and is easy to promote and apply.

Description

technical field [0001] The invention relates to an environment-friendly water-based gravure printing ink and a preparation method thereof, belonging to the technical field of printing inks. Background technique [0002] Green packaging is the development trend of the printing industry. The organic solvents and thinners of solvent-based inks contain VOC components to some extent. During the drying process, most of the volatilized solvents will pollute the atmosphere, while a small amount of solvents remaining in the printed matter will harm the human body. Water-based ink is currently recognized as an environmentally friendly ink. It uses water as a solvent carrier. No matter in its production process or when it is used for printing, it will hardly emit VOCs to the atmosphere, which is unmatched by solvent-based inks. [0003] Although water-based ink has obvious advantages in solving the problem of VOCs exceeding the standard, it also brings new challenges and problems to p...
