Future development trend of water-based inks

future development trend of water-based inks

April 26, 2020

water based inks are water-based inks, also known as water-based inks. The difference between typical ink and traditional solvent based inks is that water (or water and a few cosolvent alcohols) is used to replace the organic solvent in solvent based inks to prepare water-based binder, which is compounded with pigments (pigments or dyes), i.e. specific additives

types and advantages of common ink

at present, the industrialized products of ink are mainly acrylic ink and polyurethane ink coatings. Acrylic resin is used as the connecting material of acrylic ink, and polyurethane resin is used as the connecting material of polyurethane ink

among these two types of common ink, acrylic ink has obvious advantages in production and application. See the following table for the basic comparison between acrylic ink and polyurethane ink

advantages of water-based inks

1 Environmental protection

in the process of printing, the typical ink only emits water vapor and does not emit any volatile organic compounds. The printing site and surrounding environment are not polluted by toxic and harmful organic solvents, and the environmental protection performance is superior

2. Healthy

oily ink contains about 70% organic solvents, mainly benzene, toluene, acetone, ethyl acetate, etc., and a large amount of organic solvents (especially for surface printing, organic solvents up to times the ink quality) need to be added to dilute the ink during the printing process. These organic solvents will bring great harm to the health of production personnel and the surrounding environment

for typical ink, there is only water in the connecting material, and there is no toxic or harmful organic solvent. In printing products, if you do not press the power switch, there will be residual organic solvent

3. Safety

the safety of water-based ink is manifested in two aspects: fire safety and food safety

the warehouse and production workshop storing ink will not cause combustion, explosion and other accidents due to the existence of flammable and explosive organic solvents

after printing, the organic residual solvents in the oil-based ink will migrate and penetrate, polluting the food. The water-based ink does not contain organic residual solvents, and only acts on the surface of the printed matter. It will not migrate to the inside of the package and pollute the food

development trend of water-based inks

at present, developed countries and regions are trying to develop and use water-based inks to gradually replace solvent based inks. Packaging printing with water-based ink as its main development object has become a trend in the world. However, in China, the application of water-based ink is not very popular, and there are still some differences compared with developed countries. In this paper, we briefly analyze the reasons why there are errors in the peel strength test results of Jinan gold assay pressure test machine

industry experts believe that in the coming years, the domestic market demand for offset lithography ink, flexo ink, special ink and other products will show an upward trend, and with the strengthening of the people's awareness of environmental protection, water-based ink and other environmental friendly inks will show a rapid growth trend
