Abstract

The invention relates to a preparation method of universal water-based ink for plastic surface gravure printing. The water-based ink comprises the following components in percentage by weight: 44-80%of a water-based resin bonding material, 10-45% of deionized water, 1-10% of absolute ethyl alcohol, 3-30% of pigment, 0.1-3% of a wetting dispersant, 1-6% of a leveling agent, 1-10% of a coalescing agent, 0.1-2% of a surfactant, 0.1-5% of a regulator, 0.01-3% of an water-based defoaming agent and 0.01-3% of an anti-ultraviolet agent, and the sum of the percentages of the components is 100%. The ink provided by the invention is suitable for gravure printing of various plastic films such as biaxially oriented polypropylene (BOPP), oriented polypropylene (OPP), polyethylene (PE), polyethylene terephthalate (PET), polyamide (PA) and the like, and has the advantages of environmental friendliness, no pollution, high drying speed and the like.

Description

technical field [0001] The invention belongs to the field of inks, and relates to an ink for plastic gravure printing, in particular to a general-purpose water-based ink for plastic gravure printing and a preparation method thereof. Background technique [0002] With the enhancement of people's awareness of food safety and environmental protection, and the improvement of the country's food safety and hygiene laws, it has become a new trend to develop and promote plastic water-based gravure printing inks instead of solvent-based inks. [0003] The main components of traditional plastic gravure solvent-based inks are organic solvents, which have a large amount of VOC emissions, which have adverse effects on human health and the environment. Water-based ink is a new type of safe and environmentally friendly ink formulated mainly from water-based resins, pigments, deionized water, dispersants and other additives. Compared with traditional solvent-based inks, water-based inks ha...
