Abstract

Water-based ink used for plastic package bag printing is disclosed. The ink is prepared from, by weight, 30-40 parts of styrene-acrylate copolymer, 4-6 parts of D-806 type water-based wear-resistant wax liquid, 3-5 parts of pigment, 3-5 parts of nanometer alumina, 2-3 parts of a Glide482 type leveling agent, 1-2 parts of castor oil, 1-2 parts of benzyldimethyldodecylammonium chloride, 0.5-1 part of nanometer MoB4 clusters and 60-70 parts of deionized water. A preparing method of the ink is also disclosed. The method includes stirring and mixing the raw materials, uniformly dispersing the mixture and grinding the mixture with a ball mill to obtain the ink. The styrene-acrylate copolymer is adopted as a connecting agent of the ink, the deionized water is adopted as a solvent, and other auxiliary agents in a scientific ratio are also added, and therefore the ink has excellent wear resistance, corrosion resistance and mildew resistance, and is not liable to crust. When the ink is printed on surfaces of plastic package bags, the ink is high in drying speed, not liable to fade and high in gloss, and can play good marking and advertisement roles.

Description

technical field [0001] The invention belongs to the field of plastic woven bag printing, and in particular relates to a water-based ink for printing plastic packaging bags and a preparation method thereof. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life, and is widely used in daily life and industrial production. Although plastic packaging bags are harmful to the environment, the current usage rate is still relatively high. In the process of use, it is necessary to print ink on the surface of the plastic packaging bag for identification, publicity and other functions. [0003] Water-based ink has the advantages of environmental protection, no pollution to the environment, and no harm to human health. It has developed rapidly in the field of plastic packaging bag printing. However, water-based inks used on the surface of plastic packaging bags generally have problems su...
