Problems solved by technology

[0006] 1. As a non-volatile solvent, water is difficult to dry on substrates such as non-absorbent and permeable plastic films
[0007] 2. Water-based products have poor adhesion and rubbing fastness on non-absorbent substrates
[0008] 3. Water-based products need to be extremely hydrophilic before drying to form a film, and high-strength water resistance is required after rapid film formation, resulting in a large contrast
[0009] 4. The thermal potential characteristics of water make water-based products prone to false drying and sticking back, resulting in deinking
[0011] The publication number is CN102993823A, and the Chinese patent application with the application number 201110265646.9 discloses a water-based ink for ink-jet printing direct plate making. A certain amount of organic volatiles is added in the invention, which has a certain impact on the body and mind of industrial workers when producing the product. harm

Abstract

The invention relates to a full water-based plastic film gravure ink, which belongs to the field of industrial inks. The ink is prepared from four parts, namely, resin, color paste, a solvent and aids. The full water-based plastic film gravure ink is characterized in that the solvent part completely abandons low-boiling-point organic volatiles and adopts water; and due to use of water, a waterborne acrylic resin is selected, poly alkylene glycol which can be completely dissolved in water is taken as a main aid, lake / color source, azo, quinacridone organic pigments which can be used for preparing full water-based color paste, titanium dioxide produced by using a rutile sulfuric acid method and carbon black which can be used for preparing water-based color paste are selected. The gravure ink disclosed by the invention has the advantages that low-boiling-point organic volatiles are completely abandoned in products, thereby greatly reducing the emissions of VOC; and the gravure ink is applicable to existing medium / high-end printing equipment, and the existing medium / high-end printing equipment does not need to be significantly modified, so that the investment cost can be saved.

Description

Technical field: [0001] The invention relates to a plastic film gravure printing ink, in particular to a fully water-based plastic film gravure printing ink. Background technique: [0002] For a long time, the printing and printing ink preparation industries, including the general public, have referred to printing ink as "ink". This is because most of the materials in traditional printing inks are petroleum accessories, which have extremely strong lipophilic and hydrophobic properties. Traditional ink is prepared from four parts: resin, colorant, solvent and additive. Among them, "solvent" accounts for a large proportion. Solvents are used to dissolve substances, so solvents are required in all aspects of dissolving resins, grinding color pastes, production aids and adjusting the viscosity of printing inks. Therefore, the traditional ink industry is also called "solvent ink". In the gravure printing ink, the solvent accounts for more than 60%, and a large amount of solvent...
