Abstract

The invention discloses a water-based ink for plastic printing and a preparation method thereof. The water-based ink is prepared by using epoxy resin modified water-based polyurethane emulsion and organic silicon modified styrene-acrylic emulsion as base materials and using deionized water and alcohol as solvents. The water-based ink comprises the following components by weight percent: 15-30% of epoxy resin modified water-based polyurethane emulsion, 20-35% of organic silicon modified styrene-acrylic emulsion, 10-20% of non-toxic organic pigment, 5-30% of deionized water, 5-20% of ethanol or isopropanol, 3-5% of triethylamine and 1.6-10% of additive. The water-based ink does not contain the volatile organic solvent, is incombustible, nonexplosible and non-toxic and has high attachment fastness on the plastic film and good printing effect; the ink has high chemical resistance, acid resistance and alkali resistance; and the ink has good water resistance, heat resistance, freezing resistance and oil resistance. The ink can be widely used in the packaging and printing of the industries such as grain, vegetables, alcohol and tobacco, and food; and the safety and non-toxicity of the ink can be ensured, and the ink is a green and environmentally-friendly product and has considerable market potential.

Description

technical field [0001] The invention relates to a water-based ink for plastic printing and a preparation method of the ink. Background technique [0002] With the progress and development of society and the improvement of people's living standards, the society has higher and higher requirements for plastic flexible packaging, and the demand is increasing. The varieties and patterns of flexible packaging are becoming more and more diverse, and the usage is also increasing. For food packaging, in addition to daily use needs, people also put forward higher requirements for its environmental protection and safety. In our daily life, such as food, agricultural by-products, washing powder, instant noodles, biscuits, candies, tobacco and alcohol, medicines, cosmetics, children's toys, beverages, etc. are mostly packaged in plastic. In recent years, especially plastic woven bags have been constantly innovating. In the packaging of rice and vegetables, various colorful, novel and un...
