Problems solved by technology

[0003] During the manufacturing, printing and drying process of solvent-based gravure ink, due to the large amount of volatilization of benzophenone or ester solvents, it not only pollutes the environment, but also endangers the health of operators; UV-curable screen ink consumes a lot of energy , and the printing environment exposed to strong ultraviolet radiation for a long time will also cause certain harm to the operator

Embodiment 1

[0026] The formula is shown in the table below, and the amounts of the components are all percentages by weight.

[0027]

[0028]

[0029] Preparation method: First, stir and disperse acrylic emulsion, polyurethane emulsion, thickener and defoamer to make pre-emulsion, then add pearlescent pigment, dispersant, leveling agent, solvent, water, stir and disperse, add curing agent Bayhydur before use 304, stirred to disperse, ready to use.

[0030] The prepared water-based pearlescent gravure ink has a viscosity of 21s (25°C, 2# Chai's cup).

[0031] Use this ink to use white cardboard as the base material, and print in the last color of a ten-color gravure printing machine. The printing speed is 60m / min. The ink has good stability on the machine, the ink dries quickly, and the printed pattern is clear. The printed product adopts the national standard GBT7707- 2008 "Gravure Decorative Printing" conducted ink fastness testing, the results are as follows:

Abstract

The invention discloses a water-based evaporation drying type gravure ink composition applicable to multiple base materials. The water-based evaporation drying type gravure ink composition applicable to multiple base materials comprises the following components in percentage by weight: 20-60% of an ink linking material, 1-30% of a flaky functional material, 0-30% of an alcohol solvent, 0-10% of auxiliaries, 0-0% of a curing agent and the balance of water. The water-based evaporation drying type gravure ink composition applicable to multiple base materials contains no phenyl ketone and no ester solvent, has the characteristics of safety, no toxicity, no harm, noninflammability, non-explosiveness, nearly zero VOC and the like and is beneficial to human health and environmental safety, and defects of water-based ink composition in onboard stability and ink drying property are overcome; and by selecting resin of a specific structure, the problems of the water-based ink composition in the aspects of binding strength on a base material and printing product materialization tolerance are solved, and the ink composition can be applicable to multiple base materials such as paper and plastic.

Description

technical field [0001] The invention relates to a water-based volatile drying gravure ink composition. Background technique [0002] In recent years, with the continuous development of printing technology, the variety of gravure inks is still increasing, and the quality is still on the rise. With the continuous improvement of my country's environmental protection laws and regulations, the large-scale use of volatile solvents is also subject to stricter control. In 2007, the State Environmental Protection Administration of my country formulated and issued the "Technical Requirements for Environmental Labeling Products Gravure Ink and Flexo Ink" , the content of various solvents and heavy metals in gravure inks, and the residual amount of solvents in printed products have been clearly stipulated. This marks that my country's ink industry has entered a new era of environmental protection construction, which also makes it excellent. Environmentally friendly inks with high perform...
