Environment-friendly ink formula special for markers and preparation method thereof

Abstract

The invention discloses an environment-friendly ink formula special for markers and a preparation method thereof, and belongs to the technical field of ink. The raw materials comprise, in parts by weight, 20-30 parts of epoxy resin, 20-30 parts of 2-ethylhexyl acrylate, 5-10 parts of a natural organic pigment, 3-5 parts of a greasy leveling agent, 3-5 parts of a water-soluble organic solvent, 1-3parts of a pseudoplasticity imparting agent, 3-5 parts of a modified wetting dispersant and 3-5 parts of deionized water. According to the preparation method, natural pigments can be used for replacing synthetic coloring agents; the purpose of environmental protection is achieved; natural pigments are used, so that environment pollution is avoided, and excellent environment protection effect is achieved; base material refining is carried out, the modified dispersant is added into the ink, so that pigments are fully dispersed in the base material, the coloring effect is enhanced, ink coloringeffect is improved greatly, in using process of the markers, color is uniform, and the color is bright.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a special environmental-friendly ink formula for marking pens and a preparation method thereof. Background technique [0002] A marker pen is a pen that can write marks or signs on one or more materials such as paper, wood, metal, plastic, ceramic enamel, etc. Markers are divided into oily marker pens and water-based marker pens, and water-based marker pens can be used on smooth Writing on the surface of an object or on a whiteboard can be wiped off with a rag (whiteboard pen), and the oily marker pen is not easy to erase. The marker pen is generally composed of a pen case, a pen tip, a pen cap and a cotton core soaked in ink. The cotton core impregnated with ink is an important part of the marker. [0003] Most of the current inks in the cotton core of marker pens are composed of chemically synthesized colorants, organic solvents and other additives. However, such inks will pollut...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a special environmentally friendly ink formula for marking pens and its preparation method, which solves the problem that the existing inks will pollute the environment and have no environmental protection effect due to the fact that the synthetic coloring agent contains more toxic components. , cause harm to the health of the user, and the existing ink coloring effect is poor. When the marker pen is in use, the color is not uniform and the color is not obvious. It cannot be achieved by using natural pigments instead of synthetic colorants. To achieve the purpose of environmental protection, it is impossible to achieve the purpose of enhancing the coloring effect by refining the base material and adding a modified dispersant to the ink to fully disperse the pigment in the base material
