Abstract

The invention relates to a children watercolor pen dedicated ink capable of being scrubbed and prepared from the following components in parts by weight: 15 to 30 parts of vinisol, 5 to 20 parts of a wetting agent, 5 to 20 parts of water, 5 to 8 parts of a pigment, and the balance being ethanol. Through composition readjustment and process optimization of a conventional watercolor pen ink, the children watercolor pen ink which can be easily scrubbed is obtained; and the ink can be erased by a board eraser, also can be erased by ethanol, moreover, do not leave marks on a children drawing board after being repeatedly erased, does not need to use special erasing agents, and is quite convenient to use.

Description

technical field [0001] The invention relates to a special ink for children's watercolor pens which can be scrubbed, and belongs to the field of ink preparation. Background technique [0002] Because of its rich water content and rich and bright colors, watercolor pens are very popular painting tools for children. At present, the color pen inks commonly used in the market are oil-soluble dye-based inks, and the solvents are mainly alcohols. It is difficult to erase the handwriting written in this type of ink when it is modified. CN101845251A discloses a dry-erasable and wet-erasable water-based whiteboard ink and a wiper thereof, which have the characteristics of energy saving, environmental protection, non-toxicity, no irritating smell, and easy writing and erasing. However, the ink formula is complex, the cost is high, and it needs to use a special wiper to wipe off the handwriting, which increases the burden on the user. Contents of the invention [0003] The purpose o...
