A printing ink containing antibacterial Chinese medicinal ingredients

Abstract

The invention relates to the field of printing ink and in particular relates to printing ink containing an antibacterial Chinese herbal medicinal ingredient. The printing ink containing the antibacterial Chinese herbal medicinal ingredient is prepared from the following raw materials in parts by weight: 4-5 parts of hexacarbinal, 5-6 parts of polyacrylic acid, 4-6 parts of hydroxyapatite, 1-3 parts of zinc oxide, 25-30 parts of EVA (ethylene vinyl acetate) emulsion, 1-3 parts of enteromorpha superfine powder, 1-2 parts of glucosamine, 0.1-0.2 part of nitrilotriacetic acid, 0.3-0.5 part of isatis leaf extract, 0.1-0.2 part of coptis chinensis extract, 28-35 parts of butyl acetate, 10-12 parts of absolute ethyl alcohol, 8-10 parts of organic pigment and 2-4 parts of auxiliary. The printing ink provided by the invention has low toxicity, is environment-friendly and does small harm to the environment and a human body, isatis leaf extract and coptis chinensis extract have antibacterial and antiseptic effects, and enteromorpha superfine powder and hydroxyapatite are ground in absolute ethyl alcohol together, so that enteromorpha superfine powder and hydroxyapatite can be combined with resin and pigment more easily. The printing ink provided by the invention can be well attached after being printed on the surface of a base material and can be rapidly dried, a coating is light, thin and flexible, an imprint is clear and bright, and the coating can not fall off or discolour after being used for a long time, so that the printing ink containing the antibacterial Chinese herbal medicinal ingredient has a good market application prospect.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a printing ink containing antibacterial traditional Chinese medicine ingredients. Background technique [0002] Printing ink is a common coloring material for printed products. It is mainly composed of pigments, binders, fillers and other components. It is a kind of colored paste-like adhesive with a certain degree of fluidity. In order to obtain a satisfactory printing effect, there are certain requirements for the color, printing adaptability, and drying speed of the ink during actual use. At the same time, it must have the characteristics of water resistance, light resistance, acid and alkali resistance, low toxicity and environmental protection according to the use environment. In the future, the development direction of printing inks must be towards the direction of low toxicity, fast drying, natural and diverse colors, and multi-functionality. Ink with better performance has d...

Problems solved by technology

In order to obtain a satisfactory printing effect, there are certain requirements for the color, printing adaptability, and drying speed of the ink during actual use. At the same time, it must have the characteristics of water resistance, light resistance, acid and alkali resistance, low toxicity and environmental protection according to the use environment. In the future, the development direction of printing inks must be towards the direction of low toxicity, fast drying, natural and diverse colors, and multi-functionality. Ink with better performance has disadvantages such as high price. Therefore, it is necessary to improve the formula and process of printing ink and accelerate the transformation of the industry to achieve an efficient and environmentally friendly production mode.
