Water-based printing ink for printing PET (polyethylene terephthalate) films and method for manufacturing water-based printing ink

Abstract

The invention relates to water-based printing ink for printing PET (polyethylene terephthalate) films. The water-based printing ink comprises, by weight, acrylic hard resin emulsion, acrylic self-crosslinked soft resin emulsion, polyether-modified organic silicon leveling agents, organic siloxane adhesion promoters, organic silicon defoaming agents, polyethylene wax emulsion and water-based color paste. The invention further discloses a method for manufacturing the water-based printing ink. The water-based printing ink and the method have the advantages that the water-based printing ink for printing the PET films is excellent in water resistance and adhesion and free of fading.

Description

technical field [0001] The invention relates to the technical field of water-based inks, and relates to a water-based ink for PET film printing and a preparation method thereof. Background technique [0002] Ink is an important material for printing. Patterns and characters are printed on the surface of the substrate through different processes to form a solid coating with firm adhesion, certain strength and continuity, which can well decorate the surface of the object. Therefore, it is widely used in the printing industry. PET film is a packaging film with comprehensive performance. Its biggest feature is its excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and its tensile strength and impact resistance are strong. It is much higher than ordinary films. Therefore, PET film prints are widely used in clothing labels, food packaging and other daily necessities closely related to people. [0003] At present, the inks used in PE...
