Abstract

The invention provides environment-friendly printing ink for food packaging and a preparation method of the environment-friendly printing ink. The printing ink comprises components in parts by weight as follows: 20-30 parts of waterborne acrylic resin, 20-30 parts of a waterborne polyurethane emulsion, 10-15 parts of calcium carbonate, 15-25 parts of food-grade pigments, 5-10 parts of edible ethyl alcohol, 5-10 parts of palm oil, 5-10 parts of triethanolamine, 1-5 parts of a bacteriostatic agent, 1-5 parts of an antifoaming agent, 1-5 parts of a thickening agent and 30-40 parts of deionized water. The composition of the components of the printing ink is reasonable in design, the preparation method is simple and energy-saving, and the printing ink is environment-friendly, non-toxic and harmless, cannot damage a human body, cannot release foreign odor, and is wide in applicable range, low in production cost and good in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to an environment-friendly printing ink for food packaging and a preparation method thereof. Background technique [0002] Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain flow. Degree of paste-like adhesive body. Therefore, color (hue), body (rheological properties such as thinness and fluidity) and drying performance are the three most important properties of ink. There are many kinds of them, and their physical properties are also different. Some are very thick and sticky; while others are quite thin. Some use vegetable oil as binder; some use resin and solvent or water as binder. These are determined according to the object of printing, that is, the substrate, the print...
