Environmental-friendly printing ink containing plant adhesive and preparation method thereof

Abstract

The invention discloses environmental-friendly printing ink containing a plant adhesive, and relates to the technical field of printing. The environmental-friendly printing ink is prepared from the following raw materials: 250 to 260 parts of waterborne polyurethane emulsion, 3 to 5 parts of pigment, 2 to 4 parts of antifoaming agent, 5 to 7 parts of dispersing agent, 6 to 8 parts of polyethylene wax, 8 to 10 parts of mineral oil, 5 to 7 parts of drying agent, 40 to 50 parts of water, 2 to 4 parts of tung oil, 5 to 7 parts of linseed oil, 15 to 25 parts of starch glue, 15 to 25 parts of abietate, 20 to 30 parts of ethyl alcohol, 10 to 20 parts of Aloe vera gel, 6 to 8 parts of organic base modifier and 2 to 4 parts of water-resistant agent. The environmental-friendly printing ink has the beneficial effects that the printing ink adhesive prepared by the invention is reasonable in formula and simple in preparation process, and uses non-toxic and harmless raw materials; due to adding of the plant raw materials, the environmental-friendly printing ink is natural and healthy, not only ensures health, but also has effects of strong coloring and less possibility in decoloration, and has great advantages for environmental protection and healthy; the prepared ink can be applied in various fields, and is convenient for practical popularization and wide use.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an environmentally friendly printing ink containing a vegetable adhesive and a preparation method thereof. Background technique [0002] Ink is a uniform mixture composed of colored bodies, linking materials, fillers, additional materials and other substances; it can be printed and dried on the printed body; it is a paste-like adhesive body with color and certain fluidity. Therefore, color, body and drying properties are the three most important properties of inks. There are many types of them, and their physical properties are also different. Some are very thick and sticky; some are quite thin, and some use vegetable oil as a linking material; It is determined according to the object of printing, that is, the substrate, printing method, type of printing plate, and drying method. [0003] The linking material is a kind of viscous fluid. In the ink industry, it is to mix and li...

Problems solved by technology

[0005] Due to the continuous improvement of the binder technology, the inks prepared by the binder will have different qualities. Different raw materials used in the ink will result in different qualities. At this stage, the addition of a large number of chemical substances in the ink has a great There are great hidden dangers in its own quality and environmental protection performance. This kind of ink is used in the printing industry, which has immeasurable hidden dangers to the environment and human health.
