Embodiment 1
[0020] A printing ink with high stability, the coating is composed of the following raw materials in weight percentage: 10% modified alkyd resin, 2% kaolin, 2% dispersant, 2% white carbon black, 0.8% pigment, 0.5% surfactant, Talc 0.6%, ethanol 2%, isopropanol 2%, conditioner 2%, and the rest is water.
Embodiment 2
[0022] A printing ink with high stability, the coating is composed of the following raw materials in weight percentage: 20% modified alkyd resin, 6% kaolin, 6% dispersant, 6% white carbon black, 1.8% pigment, 2.8% surfactant, Talc 2.6%, ethanol 6%, isopropanol 6%, conditioner 4%, and the rest is water.
[0023] A printing ink with high stability, the pigment is one of titanium dioxide, iron oxide red, carbon black, barium sulfate or chromium oxide green. The surfactant is sodium dodecylbenzenesulfonate. The modulator is gibberellin. The dispersant is sodium tripolyphosphate.

Abstract
The invention discloses a printing ink with high stability, and belongs to the technical field of printing; the printing ink consists of the following raw materials by the weight percentage: 10-20% ofmodified alkyd resin, 2-6% of kaolin, 2-6% of a dispersant, 2-6% of white carbon black, 0.8-1.8% of a pigment, 0.5-2.8% of a surfactant, 0.6-2.6% of a talcum powder, 2-6% of ethanol, 2-6% of isopropanol, 2-4% of a regulator, and the balance water. The preparation principle is clear and the components are scientific. Compared with a traditional printing ink, the prepared printing ink is nontoxic and smell-less, is suitable for various types of gravure and rotary flexo printing processes, and has good transferability and fastness to adhesion; a mixed solvent is prepared from a variety of liquids in the ink, so that the ink is mixed evenly, has high gloss of a printing ink layer, has good transparency and water resistance, meets the environmental-protection use requirements for the printingink and improves the adhesion and drying performance of the printing ink.
Description
technical field [0001] The invention belongs to the technical field of printing, and relates to a printing ink and a preparation method thereof, in particular to a printing ink with high stability 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 (thickness, fluidity and other rheological properties) and drying performance are the three most important properties of ink. There are many types 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 the linking material; some use resin and solvent or water as the linking material. These are determined according to the...
