Abstract

The invention discloses environment-friendly printing ink. The environment-friendly printing ink contains the following raw materials in parts by weight: 40-60 parts of modified water-based acrylic resin, 5-10 parts of nano-composite fillers, 3-5 parts of a functional aid, 10-20 parts of soybean oil fatty acid ethyl ester, 3-5 parts of an anti-skinning agent, 25-30 parts of a coupling agent, 1-3 parts of a defoamer and 5-10 parts of a slipping agent. The invention further discloses a preparation method of the printing ink. The modified water-based acrylic resin, the soybean oil fatty acid ethyl ester and the coupling agent are taken as the main materials, and the nano-composite fillers, the functional aid, the anti-skinning agent, the defoamer and the slipping agent are added to prepare the printing ink, and the prepared printing ink does not contain heavy metal additive and harmful organic additive and has the characteristics of environmental friendliness, no pollution, high heat resistance, good adsorbability and high antibacterial performance.

Description

technical field [0001] The invention belongs to the field of ink manufacturing, and in particular relates to an environmentally friendly printing ink and a preparation method thereof. Background technique [0002] Ink is a homogeneous mixture composed of colored bodies (such as pigments, fuels, etc.) binders, fillers, additives and other substances; it can be printed and dried on the printed matter, and it is a paste-like glue with color and certain fluidity slime. Therefore, color (hue), body (thickness, fluidity and other rheological properties) and drying performance are three important properties of ink. The ink has a lot of weight and different physical properties, some are very thick and sticky, some use vegetable oil as a binder, and some use resin and solvent or water as a binder. These are determined according to the printed object, that is, the substrate, the printing method, the type of printing plate and the drying method. [0003] In the prior art, the irrita...
