Problems solved by technology

[0003] In short, the traditional solvent-based ink has the following disadvantages: 1) It is flammable and explosive, and there are great safety hazards in production; 2) A large amount of VOC toxic organic substances are discharged into the air, polluting the air; 3) Solvent is a toxic thing that affects affect the health of employees; 4) Solvent residues pollute food and affect the health of consumers; 5) A large number of solvents evaporate and waste, resulting in increased costs

Abstract

The invention discloses a composite special water-based ink for plastic inner printing, comprising the following components by weight ratio: 55-65 parts of water-based acrylic emulsion with a Tg (triglyceride) value being minus 40-25 DEG C, 25-35 parts of water-based color paste, and 3-4 parts of water-based assistant, wherein the water-based assistant comprises 0.2-0.5 part of water-based wetting agent, 0.5-0.8 part of water-based dispersing agents with a medium pH value, 0.5-0.8 part of water-based leveling agent, 0.5-2 part of water-based quick drying agent, and 0.5-1 part of water-based adhesion promoter. The ink has neither residual solvent nor pollution to food packaging, and is healthy, green and safe. A printing product of the ink has the characteristics of high gloss, friction resistance, anti-reverse adherence, high adhesion, high temperature resistance, an excellent leveling property, a saturated and brilliant color, wonderful color expression and the like.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to an environmentally-friendly water-based ink specially used for composite printing on plastic backs. Background technique [0002] For a long time, ink pollution has been the most serious problem in the printing industry. The annual output of ink in the world has exceeded 3 million tons. Solvent-based inks account for 30% to 40% on average, and the amount of organic solvents brought by inks worldwide is as high as 1 million tons per year, resulting in a huge waste of resources. Among them, organic solvents such as ethanol, butyl acetate, toluene, and xylene are often used. Most of it will be eliminated after drying, but the remaining part will still cause harm to the human body. Long-term contact will make the skin dry and rough. If it penetrates into the skin or blood vessels, it will endanger the human blood cells and hematopoietic function with the blood, and may even cause chron...
