A water-based acrylic printing ink with color-fixing and waterproof effect

Abstract

The invention relates to the field of printing ink, and in particular to a waterborne acrylic printing ink with dye fixation and waterproof functions. The ink is prepared from the following raw materials by weight: 0.2-0.3 part of iron nitrate, 1-2 parts of anhydrous sodium sulfate, 6-8 parts of aluminum oxide, 3-5 parts of nano silicon, 25-30 parts of water soluble acrylic resin, 5-8 parts of gelatin, 0.4-0.5 part of bismuth octoate, 10-12 parts of waterborne pigment, 20-25 parts of deionized water and 2-4 parts of an auxiliary. The printing ink of the invention uses water as a solvent medium, which is low in toxicity and environment-friendly; a mixed solution of ferric nitrate and anhydrous sodium sulfate is used for pretreatment of the waterborne pigment, in order to improve its compatibility with resin emulsion and enhance the stability of the pigment; and the waterborne pigment is then combined with the other ingredients to gain good drying speed, controllable slurry viscosity and good thixotropy. The waterborne pigment is fast and efficient in printing, bright and lasting in ink color, and easy for cleaning, can resist water and moisture after drying, and has strong market competitiveness.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a water-based acrylic printing ink with color-fixing and waterproof effects. 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 disadv...

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.
