Printing ink containing modified seashell mud

Abstract

The invention relates to the field of printing ink, and particularly relates to printing ink containing modified seashell mud. The ink is prepared from the following raw materials in parts by weight: 4-6 parts of polyvinyl acetate, 4-5 parts of liquid paraffin, 4-5 parts of urea-formaldehyde molding powder, 6-8 parts of seashell mud, 22-24 parts of drying oil alkyd resin, 10-12 parts of epoxy resin, 6-8 parts of organic pigment, 3-5 parts of white carbon black, 25-30 parts of polypropylene glycol diglycidyl ether and 2-4 parts of adjuvant. The printing ink is low-toxic and environment-friendly and has small hazard to the environment and human bodies; the seashell mud which is mixed with the liquid paraffin and grinded has excellent effects of resisting water and flame, keeping wall surface clean, sterilizing, deodorizing and the like, is well compatible with resin, pigment and other ingredients, and is combined with the urea-formaldehyde molding powder, the adjuvant and other auxiliary components, so that the printing ink is uniform in color distribution and strong in adhesion, has high stability and no fine-lines or cracking after being dried, and has the advantages of smooth surface, wear resistance and strong market competitiveness.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a printing ink containing modified seashell mud. 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 such as high price. ...

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.
