Abstract

The invention relates to water-based ink for printing a thin film and a preparation method thereof. The water-based ink is prepared from the following raw materials in parts by weight: 28-35 parts of acrylic resin, 10-20 parts of epoxy resin, 12-20 parts of a pigment, 6-12 parts of wollastonite powder, 2-7 parts of nano bentonite, 4-9 parts of a sterilization mildew-proof agent, 0.5-3 parts of epoxy soybean oil, 1-4 parts of polyurethane, 0.5-2 parts of a surfactant, 0.5-2 parts of silane and 26-38 parts of de-ionized water. According to the water-based ink provided by the invention, the wollastonite powder is added so that the wearing resistance and anti-adhesion property of the ink can be improved; the added sterilization mildew-proof agent is prepared from Chinese herbal medicine ingredients, is safe and environment-friendly and has no injuries to health of human bodies; the ink provided by the invention has stable performance, good glossiness and dispersity and high drying speed; and in a utilization process, the ink does not fall off and is not faded, and the printing effect is lasting.

Description

technical field [0001] The invention relates to printing ink, in particular to a film printing water-based ink and a preparation method thereof. Background technique [0002] Today, a wide variety of plastic films are widely used in the printing and packaging industries. In many cases, these films are printed with text and images, and in order to make the printing quality meet the requirements of use, a certain understanding of the preparation of printing inks is required. Common printing inks are divided into three types: solvent-based inks, water-based inks and light-curable inks. With the aggravation of global environmental pollution and ecological environment damage, people pay more and more attention to life, environment and human development, and increase the production and use of green products. Water-based inks are widely used in the printing and packaging industries. [0003] Water-based ink is mainly a uniform paste-like substance composed of colorants and binde...
