Alcohol soluble white board marker ink easy to dry-erase and preparation method thereof

Abstract

The invention relates to alcohol soluble white board marker ink easy to dry-erase and a preparation method thereof. The alcohol soluble white board marker ink comprises, by weight, 4.0-12% of macromolecule pigment, 30-60% of ethanol, 20-50% of isopropanol, 0.4-3.0% of polyvinyl butyral (PVB), 0.4-3.0% of fatty alcohol-polyoxyethylene ether, 0.4-3.0% of Solsperse series of hyperdispersant, 0.4-3.0% of glycerol, 0.1-3.0% of triethanolamine, 0.1-3.0% of paroline, 4.0-12% of laurate and 4.0-10% of butyl stearate. The preparation method includes: under the normal temperature and pressure, adding ethanol and isopropanol into a preparation vessel, then adding fatty alcohol-polyoxyethylene ether, Solsperse series of hyperdispersant, glycerol, triethanolamine, paroline, laurate and butyl stearate, then adding PVB, stirring evenly, finally adding the macromolecule pigment, and stirring for 4-8 h to obtain the ink. After the ink is dropped on the whiteboard, the ink is good in film-forming property, even in film coating, bright in color and good in stability. The preparation method is simple and easy to practice.

Description

technical field [0001] The invention relates to ink, in particular to a formula of easy-dry-erase alcohol-soluble whiteboard pen ink and a preparation method thereof. Background technique [0002] Whiteboard pen ink is a new type of ink that can be written on a smooth non-absorbent hard whiteboard. The whiteboard pen filled with this ink writes smoothly, bright in color, dust-free and erasable, environmentally safe, easy to carry, and is expected to replace traditional Chalk is widely used in teaching, office and other occasions. [0003] The development of foreign whiteboard pen ink began in the 1950s, and Japan's OKI Electric Company first began to develop it, and then Switzerland, Germany, and the United States also launched such products one after another. The performance of whiteboard pen ink has been continuously improved for decades, and the formula and process have made a qualitative leap, especially its main component solvent, which has developed from the early tox...

AI Technical Summary

Problems solved by technology

At present, the composition of domestic whiteboard pen ink is similar to that of foreign countries, and environmentally friendly alcohol solvents are mostly used, but the preparation process is complicated and the production energy consumption is large. -30 hours; "An alcohol-soluble whiteboard pen ink (application number 200810035471.0)" requires ultra-fine sanding, pressurized heat preservation, and shear dispersion
