Method for multifunctional water-based ink

Abstract

The invention provides a multifunctional water-based ink, which comprises the following components by weight percent: 25 to 35 percent of water-soluble acrylic resin, 10 to 20 percent of paint, 3 to 10 percent of silicon oxide, 15 to 25 percent of water, 5 to 15 percent of complex solubilizer, 5 to 10 percent of neutralizing agent, 1 to 3 percent of emulsifier, 0.2 to 1 percent of antifoaming agent, 5 to 9 percent of dispersant, 0.2 to 1 percent of antistatic agent, and 0.1 to 1 percent of anti mildew agent. The multifunctional water-based ink is a novel printing water-based ink which is nontoxic, odorless and low in comprehensive price, and has watertight, anti-mildew and antistatic functions and other functions.

Description

technical field [0001] The invention relates to a multifunctional water-soluble ink. It is an environmentally friendly printing ink, which has printing adaptability and good mechanical properties, and belongs to the field of fine chemicals or coatings. Background technique [0002] With the continuous development of ink technology to high technology and the continuous improvement of people's awareness of environmental protection, the development of environmentally friendly inks must be considered first in the development of inks in the future. Environmentally friendly inks mainly change the ink composition, that is, use environmentally friendly raw materials to prepare new inks. At present, environmentally friendly inks mainly include water-based inks, UV inks, water-based UV inks and some alcohol-soluble inks. Among them, water-based ink is a kind of "green" printing material that is being promoted. The biggest difference between water-based ink and solvent ink is that t...

AI Technical Summary

Problems solved by technology

[0004] At present, in the entire printing industry of our country, almost all the inks used are oil-soluble inks. The solvents are benzene or benzene-like compounds, which are flammable, volatile, and disperse into the air to pollute the air, seriously endangering workers and people around them. health, some even cause occupational diseases

Although water-based inks have been developed on the market, they often have single functions and poor printing adaptability

For example: water-based ink for corrugated boxes is easy to absorb moisture, and it is easy to decolorize after absorbing moisture, etc.

Many packaging products printed with water-based inks are prone to mildew, seriously affecting the appearance of the packaging products, and even unable to form effective protection for the packaged objects

Poor adhesion and non-wear-resistant ink film are also a serious defect of today's water-based inks. Some printing inks with high hygiene requirements have strict restrictions on heavy metals such as lead and arsenic, which also makes many inks on the market fail to meet the standards.
