preparation example Construction

[0029] The preparation method of the above-mentioned erasable water-based whiteboard pen ink is specifically implemented according to the following steps:

[0030] Step 1, weigh 4-6% of the coloring agent, 1.5-4% of the film-forming agent, 75-85% of the solvent, and 9.5-16% of the auxiliary agent according to the mass percentage, and the sum of the mass percentages of the above components is 100%. The agent is one or more of surfactant, humectant and lubricant, ethanol;

[0031] Step 2, adding the film-forming agent into the solvent, and stirring until completely dissolved under the condition that the temperature of the water bath is 80-85° C., to obtain System I;

[0032] Step 3, adding the lubricant into ethanol and stirring evenly to obtain System II;

[0033] Step 4: After mixing system I and system II, add surfactant, colorant and moisturizer respectively, and stir for 6-7 hours to obtain erasable water-based whiteboard pen ink.

[0034] The invention provides a green, ...

Embodiment 1

[0036] Add 1.5g of polyvinyl alcohol 1788 and 85g of deionized water into a round-bottomed flask, heat and stir in a water bath to dissolve completely at 80°C to obtain system I.

[0037] Add 0.2 g of zinc stearate into 5 g of warm ethanol and stir evenly to obtain System II.

[0038] Add system I and system II into a beaker, and then add 3.5g of surfactant OP-10, 4.0g of carbon black, and 0.6g of glycerin. The beaker was placed on a magnetic stirrer and stirred for 6 hours to obtain ink samples.

Embodiment 2

[0040] Add 4.0g of polyvinyl alcohol 1788 and 75g of deionized water into a round-bottomed flask, heat and stir in a water bath to dissolve completely at 80°C to obtain System I.

[0041] The butyl stearate of 1.3g is joined in the ethanol of 8g and stirs evenly. System II was prepared.

[0042] Add system I and system II into a beaker, and then add 5.5 g of surfactant sodium dodecylbenzenesulfonate, 5.0 g of carbon black, and 1.2 g of xylitol. The beaker was placed on a magnetic stirrer and stirred for 6 hours to obtain ink samples.

Abstract

The invention discloses erasable water-based white board marker ink. The erasable water-based white board marker ink is prepared from components in percentage by mass as follows: 4%-6% of a colorant, 1.5%-4% of a film-forming agent, 75%-85% of a solvent and 9.5%-16% of an assistant, and the sum of the mass percentages of the components is 100%, wherein the assistant adopts one or more of a surfactant, a humectant, a lubricant and ethanol. The erasable water-based white board marker ink is prepared from water-based carbon black, polyvinyl alcohol 1788 and deionized water as main raw materials, is free of odor, erasable, non-toxic and environment-friendly, guarantees clear writing and solves the problems of strong odor, board staining as well as surface wettability caused by overhigh surface tension of the white board marker in the market at present..

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an erasable water-based whiteboard ink, and also relates to a preparation method of the water-based whiteboard ink. Background technique [0002] Whiteboard pen ink is a new type of ink that can be written on a smooth non-absorbent hard board. The whiteboard pen made with this ink is smooth in writing, bright in color, dust-free and easy to carry, and is widely used in teaching and office work. And other occasions, are adapting to the rapid development trend of teaching aids and office supplies to environmental protection. [0003] Whiteboard pen ink can be roughly divided into three categories according to different solvents: oily, alcohol-soluble and water-based inks. At present, the whiteboard pen ink commonly used in the market is alcohol-soluble, has a strong smell, is flammable and volatile, has many kinds of additives, complex preparation process, and inconvenient storage. Lo...
