Example Embodiment

[0014] Example 1

[0015] Mix 20g of vinyl acetate resin, 6g of pigment, and 10g of wetting agent, and use a two-roller high-speed shearing. The shearing temperature does not exceed 35℃, and the shearing speed is 1800 revolutions / min. After fully fusion, transfer 54g ethanol and 10g Stir fully in an aqueous solution prepared with water to obtain a scrubbing ink for children's watercolor pens.

Example Embodiment

[0016] Example 2

[0017] Mix 20g of vinyl acetate resin, 8g of pigment, and 13g of wetting agent. High-speed shearing on a two-roll machine, the shearing temperature does not exceed 35℃, and the shearing speed is 1500 revolutions / min. After fully fusion, transfer into the mixture of 47g ethanol and 12g Stir fully in an aqueous solution prepared with water to obtain a scrubbing ink for children's watercolor pens.

Example Embodiment

[0018] Example 3

[0019] Mix 25g of vinyl acetate resin, 5g of pigment, and 10g of wetting agent, and use a two-roller high-speed shearing.

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 scrubbing special ink for children's watercolor pens, which belongs to the field of ink preparation. Background technique [0002] Because of its sufficient moisture, rich colors and bright colors, watercolor pens are a drawing tool that children like very much. The color pen inks commonly used in the market are oil-soluble dye-based inks, and the solvents are mainly alcohols. The handwriting written by this type of ink is difficult to erase when it is modified. CN101845251A discloses a water-based whiteboard pen ink capable of dry erasing and wet erasing and its wiper, which has the characteristics of energy saving, environmental protection, non-toxic, non-irritating odor, easy to write and easy to erase. However, the ink formulation is complicated, the cost is relatively high, and a special wiper needs to be used for wet erasing to remove the writing, which increases the burden on the user. Summary of the invention [0003] The...
