Problems solved by technology

But at present, domestic water-based inks cannot meet these needs, and the traditional old process is to stir and dissolve resin, aminating agent and water into resin liquid, then add additives and pigments, and grind into ink
This process has the following disadvantages: 1. The pigment powder is easy to fly when the materials are mixed, causing pollution hazards to the production site and production personnel. It requires dust adsorption and recovery equipment, which requires a lot of investment; 2. The product needs to be ground several times to achieve the required fineness. It takes a long time and needs a cooling device, which consumes a lot of power; 3. The product is single

Description

technical field [0001] The invention relates to the field of inks, in particular to a water-based gravure aluminum foil ink and its preparation process and application. Background technique [0002] At present, domestic flexible packaging industry manufacturers, especially food, medicine and tobacco, mostly use gravure printing. At present, in my country, a large number of inks used in the gravure printing process are basically solvent-based inks. The organic volatilization of these solvent-based inks If the waste is not treated, it will be directly discharged into the air of the workshop, which will not only have a certain impact on the production environment, but will also cause great harm to the health of workers. This is because these solvent-based inks contain 50-60% organic volatile substances. In addition, in the actual production process, the thinner required to adjust the viscosity of the ink is usually added, so when the printed matter is dry, the ink emitted is Th...
