A water-based acrylic printing ink containing modified animal bone

Abstract

The invention relates to the field of printing ink and in particular relates to water-based acrylic printing ink containing modified animal bones. The printing ink is prepared from the following raw materials in parts by weight: 5-6 parts of animal bones, 1-2 parts of tartaric acid, 0.2-0.3 part of potassium acetate, 4-6 parts of light calcium carbonate, 3-5 parts of silicone oil, 0.1-0.2 part of copper oxide, 25-30 parts of water-based acrylic resin, 20-40 parts of deionized water, 5-8 parts of polyethylene glycol, 7-10 parts of water-based pigments and 2-4 parts of aids. The printing ink is water-based ink and hardly causes harm to the environment and a human body, the water-based pigments are more easily dispersed and has higher environmental oxidation resistance after being pretreated in a mixed solution of tartaric acid, potassium acetate and polyethylene glycol; the calcined animal bone powder is fine and smooth and can be well dispersed into the slurry, so that the wear resistance and weather resistance of the printing ink are improved. The printing ink provided by the invention can be attached to multiple base materials, is corrosion-resistant, wear-resistant, bright in color after printing, smooth in handfeel, controllable in viscosity and good in leveling property, the printing production efficiency can be improved, and high printing quality is obtained.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a water-based acrylic printing ink containing modified animal bones. 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 disadvantages ...

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.
