Water-based tasteless printing ink

Abstract

The invention discloses water-based tasteless printing ink in the technical field of ink, the water-based tasteless printing ink is prepared from the following raw materials in parts by weight: 15-25parts of water-soluble acrylic resin; 5-8 parts of an aminating agent; 6-9 parts of absolute ethanol; 8-12 parts of carbon black color paste; 15-25 parts of pure water; 1-3 parts of a stabilizer; 1-3parts of an adhesive remover and 2 to 4 parts of an anti-drying agent, the water-based tasteless printing ink is relatively stable in heating or cooling, has small fluidity difference, moderate viscosity, and moderate drying speed, does not cause problems such as dirty printing plates and the like, and has reasonable glossiness.

Description

technical field [0001] The invention discloses a water-based odorless printing ink, and specifically belongs to the technical field of ink. Background technique [0002] At present, more than 95% of the printing of domestic plastic flexible packaging is by gravure printing. Commonly used printing inks in China are generally made of chlorinated polymers. In the process of production and use, aromatic solvents such as strong solvent toluene need to be used to dissolve and adjust the viscosity of the ink. Therefore, a large amount of Harmful gas, destroying the ozone layer of the atmosphere, will cause harm to the health and safety of the staff (fire risk), and the safety of food flexible packaging products is also very poor. Benzene is very easy to remain in the dry ink micro-film layer, and xylene is easier Cause the increase of benzene residue, benzene residue will contaminate the food in the package. At present, although alcohol-soluble ink is more environmentally friendl...

Problems solved by technology

Commonly used printing inks in China are generally made of chlorinated polymers. In the process of production and use, aromatic solvents such as strong solvent toluene need to be used to dissolve and adjust the viscosity of the ink. Therefore, a large amount of Harmful gas, destroying the ozone layer of the atmosphere, will cause harm to the health and safety of the staff (fire risk), and the safety of food flexible packaging products is also very poor. Benzene is very easy to remain in the dry ink micro-film layer, and xylene is easier Resulting in an increase in benzene residues, benzene residues will contaminate the food in the package

At present, although alcohol-soluble ink is more environmentally friendly, it still pollutes the environment and there will be solvent residues. The PEC (polyethylene) film made of flexible packaging has poor leakage resistance and strong adsorption, and it is very easy to pollute the PE film in the package with acetic acid. The unpleasant smell of ethyl ester, water-based plastic ink, as a substitute for solvent-based ink, is recognized by more and more domestic color printing and packaging industries for its non-flammable and green characteristics, and is also recognized by ink manufacturers and society. Attention, inks in flexible packaging printing, completely water-based has become an inevitable trend
