Problems solved by technology

[0003] Whiteboard pen ink currently has water-soluble formula and alcohol-soluble formula, but the water-soluble formula has a fatal disadvantage: it is not easy to dry, difficult to wipe
[0005] In addition to the problem of strong odor, the whiteboard pen ink used in the world is difficult to erase after a certain period of time (usually within 1 week). Therefore, how to extend the erasable validity period of the handwriting is even more The Urgent Matter of Perfecting Whiteboard Pen Ink Performance
[0006] In summary, there is a lack of a whiteboard pen ink that solves the problem of alcohol-soluble ink having a large and unpleasant smell, and can extend the erasable validity period of its handwriting

preparation example Construction

[0085] The preparation method of the present invention may further include a shearing dispersion step, specifically, the shearing dispersion step is also performed after the above-mentioned sanding composition is discharged to obtain the whiteboard pen ink.

[0086] Those skilled in the art can understand that the composition is fed at one time or in batches, both of which belong to the scope of the present invention. When feeding at one time, for example, all the components of the composition are subjected to a sanding step, and the shear dispersion step is performed after discharge; when feeding in batches, for example, part of the solvent component and the matting agent of the composition are added during shear dispersion .

[0087] In a specific embodiment of the present invention, the preparation method is as follows:

[0088] Formula: 1-10% of pigment, 60-95% of lower fatty alcohol (including polyol), 2-10% of resin, 1-10% of auxiliary agent (including dispersant, plast...

Embodiment 1

[0102] According to the formula, 10g of carbon black, 40g of ethanol, 18g of propylene glycol, 10g of resin polyvinyl butyral, 4g of dispersant CH-10S, 4g of plasticizer sebacate, 3g of humectant decaglyceryl laurate, peeling 5g of liquid paraffin, 4g of wetting agent W-9700, 18g of water and other materials were added, pre-mixed for 2 hours, and then subjected to ultra-fine sanding. Material; according to the requirements, use 30g of isopropanol and 66g of ethanol as a solvent, add 4g of matting agent to prepare, and obtain the finished whiteboard pen ink after shearing and dispersing for 1 hour.

Embodiment 2

[0104] According to the formula, 10g of pigment, 30g of ethanol, 10g of isopropanol, 10g of glycerol, 10g of resin carboxymethyl cellulose, 4g of dispersant CH-10S, 4g of plasticizer adipate, and humectant ten polyglycerol lauryl Add 3g of acid ester, 5g of stripping agent liquid paraffin, 4g of wetting agent HX-5810, and 10g of water, pre-mix for 1 hour, and then perform ultra-fine sanding. The temperature is controlled at 40-60°C, and the pressure is about 7 After 1 hour, the material is discharged; according to the requirements, use 95g of ethanol as a solvent and 5g of a matting agent to prepare, and after shearing and dispersing for 5 hours, the finished whiteboard pen ink is obtained.

Abstract

The invention provides a composition of alcohol-soluble ink for a white board marker, which contains the following ingredients according to percentage by weight: 1 to 10 of paint, 60 to 95 of C1-C10 fatty alcohol, 2 to 10 of film-forming resin, 1 to 15 of addition agent used for ink and 1 to 10 of water. The composition can be prepared into ink for the white board marker, which can solve the problem of heavy and unsavory odor of alcohol-soluble ink and extend the erasable effective period of handwriting.

Description

technical field [0001] The invention relates to an ink, in particular to an alcohol-soluble whiteboard pen ink. Background technique [0002] Whiteboard pen ink is a new type of writing ink, which has a production history of more than 20 years abroad. Its development is a comprehensive subject connected with organic synthesis chemistry, colloid chemistry, surface physics and other disciplines, which requires the cooperation of modern chemical analysis and physical detection means; In order to monopolize the technology in this field, ink-producing countries have adopted a strategy of closed technology. The key technology will never be transferred (transferred), even at the technical level. Therefore, the performance of whiteboard pen ink in each country has its own characteristics. [0003] Whiteboard pen ink currently has water-soluble formula and alcohol-soluble formula, but the water-soluble formula has fatal shortcomings: it is not easy to dry and difficult to wipe. Esp...
