Problems solved by technology

Traditional printing inks for plastic woven bags are oily and alcohol-soluble. Although there are strict requirements on solvent residues, there are still problems such as harm to human health, the impact of residual odor of solvents after printing, and food safety.
The country has banned aromatic solvents similar to toluene from food packaging printing inks, and other developed countries have relevant environmental protection laws to control the release of volatile organic compounds; It is directly required that the ink used must be water-based ink, while the previous water-based ink has a lower water resistance level, and most of them are only used for the packaging of dry items

Abstract

The invention relates to a water-solubility printing ink and a method for preparing the same, in particular to a printing ink for a water-solubility waterproof plastic woven bag and a method for preparing the same. The printing ink for the water-solubility waterproof plastic woven bag is prepared by the following compositions in percentage by weight: 30 to 55 percent of crylic acid added rosin resin, 8 to 12 percent of nontoxic pigment, 12 to 20 percent of water, 8 to 12 percent of ammonia, 10 to 15 percent of pure acrylic emulsion, 3 to 6 percent of water-based wax, 0.1 to 1 percent of defoaming agent and 0.3 to 1 percent of flatting agent, which are in mass percentage. The printing ink solves the disadvantages of a solvent-type plastic woven bag after being printed by the printing ink has the influence of odor of the residual solvent; and a water-based woven bag after being printed has the poor water resistance, etc. The product can be widely used in the packaging printing of the plastic woven bag of grain, vegetable, tobacco, food, solid beverage and other industries, in particular to farm and sideline products, food and other aspects which relate to the packaging of hydrous products. The printed product can ensure safety and nontoxicity, can not produce the harm to human health and is a green and environment-friendly product.

Description

technical field [0001] The invention relates to a water-soluble ink and a preparation method thereof, in particular to a water-soluble ink for water-resistant plastic woven bags and a preparation method thereof. Background technique [0002] In recent years, plastic woven bags have been continuously introduced. In the packaging of rice and vegetables, various colorful, novel and unique plastic packaging bags with rich pictures and texts are rushing to the market. The packaging and printing of these plastic woven bags are inseparable from people's lives; Due to the improvement of consumers' awareness of environmental protection, they are very concerned about the safety and environmental protection of packaging and printing. Traditional printing inks for plastic woven bags are oily and alcohol-soluble. Although there are strict requirements on solvent residues, there are still problems such as harm to human health, the impact of residual odor of solvents after printing, and fo...
