Water-based narrow coated paper flexible printing ink and method for preparing same

Abstract

The invention relates to the ink technical field, and in particular relates to water-based narrow coated paper flexible printing ink and a method for preparing the same. The water-based narrow coated paper flexible printing ink comprises the following raw materials in parts weight: 30-45 parts of self-crosslinking water-based acrylic emulsion, 20-28 parts of modified water-based acrylic resin, 15-20 parts of yellow pigment powder, 1-3 parts of pigment dispersant, 0.2-0.8 parts of organic silicon defoamer, 1-4 parts of nonionic organic surfactant, 2-6 parts of dodecanol ester, 3-8 parts of PH stabilizer, 3-5 parts of anionic surfactant and 5-10 parts of water. The water-based narrow coated paper flexible printing ink provided by the invention is environment-friendly and non-toxic, good in use security, stable in performance and good in printing adaptability to coated paper, and has excellent color rendering property, good glossiness and good product quality.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a water-based flexographic ink for narrow-width coated paper and a preparation method thereof. Background technique [0002] Flexographic ink was originally called aniline ink, and the name of aniline ink is due to the use of aniline dyes in the earliest ink formulations. Initially, flexographic inks were only used for printing paper bags, and later the scope of use gradually expanded. Today, most of the use of flexographic inks is concentrated in the field of packaging printing, accounting for about 85%, such as various plastic films, metal foils, cardboard, Decorative wrapping paper, glass cloth, kraft paper, etc. However, although this ink has good processing performance after printing, fast drying, and good printing adaptability, it is easy to produce a large amount of benzene and ketone gases that are easy to pollute the air during the printing process, and the printing enviro...

Problems solved by technology

[0003] The Chinese invention patent with application number 200310112057.2 discloses a water-based plastic composite ink, which is composed of anionic polyurethane dispersion, acrylate emulsion, pigment, imide crosslinking agent, defoamer, water and very little isopropyl Prepared from alcohol, this ink can meet the requirements of environmental protection packaging, with good adhesion fastness and good printing adaptability. The use range at ambient temperature is small, and the ink layer formed at low temperature is compared with the ink layer formed at normal temperature, the surface of the ink layer formed at low temperature will be rough, dull, or even cracked. Causes strong light scattering and poor printing effect, it is difficult to meet people's requirements for high-grade printing of food packaging
