Embodiment 1
[0026] A water achromatic solid whiteboard marker and a preparation method thereof, specifically comprising the following steps:
[0027] (1) Take 20 parts of sorbitol, 10 parts of octadecanoic acid, 3 parts of dodecanoic acid and 2 parts of alkyl sodium sulfate, put them into a high-temperature furnace, raise the temperature of the high-temperature furnace to 70-110 ° C, wait for 0.5-1.5 After h, the above-mentioned mixed raw material turns into liquid state;
[0028] (2) Turn on the disperser, the speed of the disperser is 800-1000r / min, after working for 10-20min, add 10 parts of fatty alcohol polyvinyl ether sodium sulfate into the high temperature furnace, and continue working for 10-20min;
[0029] (3) Take 2 parts of sodium hydroxide, put it into a stainless steel container, and then add 2 parts of water. After the sodium hydroxide is melted, put it into the high-temperature furnace of the above step (2), start the disperser, and the speed is 800-1000r / min, add 2 part...
Embodiment 2
[0034] The manufacturing steps are the same as in Example 1, wherein the phenolphthalein in step (5) is replaced with thymolphthalein to obtain a blue whiteboard marker.
Embodiment 3
[0036] With the manufacture step of embodiment 1, wherein the addition weight portion of sorbitol is 35 parts, and the addition weight portion of octadecanoic acid is 25 parts, and the addition weight portion of dodecanoic acid is 8 parts, and the addition weight portion of alkyl sodium sulfate is 7 parts, the addition weight portion of fatty alcohol polyvinyl ether sodium sulfate is 15 parts, the addition weight portion of sodium hydroxide is 5 parts, the addition weight portion of water is 6 parts, the addition weight portion of dealdehyde alcohol is 5 parts, phosphoric acid The added weight part of trisodium is 10% of A material, and the added weight part of phenolphthalein is 3% of A material.

Abstract
The invention discloses a water decoloration solid whiteboard marker and a preparation method thereof. The preparation method specifically comprises adding sorbitol, octadecanoic acid, dodecanoic acidand sodium alkyl sulfate into a high-temperature furnace, heating and mixing into liquid; stirring and dispersing, and then adding sodium fatty alcohol polyvinyl ether sulphate; adding sodium hydroxide into a stainless steel container, then adding water, adding the mixture into the high-temperature furnace after the sodium hydroxide is dissolved, dispersing and mixing, and then adding dealdehydedalcohol for mixing; putting the mixed raw materials into a forming mold, and cooling to obtain a material A; putting the material A into a high-temperature furnace, melting at high temperature, thenadding trisodium phosphate, dispersing and stirring, then adding phenolphthalein, slowly injecting the mixture into a forming mold after the mixture becomes red, and cooling and forming to obtain thered solid whiteboard marker. According to the prepared fixed whiteboard marker and the preparation method thereof, the trouble that ink pen liquid on the original market needs to be filled is solved,and the problem that strokes are broken when the writing amount of a liquid pen is large is solved.
Description
technical field [0001] The invention relates to the field of whiteboard markers, in particular to a water-achromatic solid whiteboard marker and a preparation method thereof. Background technique [0002] With the development of my country's education and the update of basic teaching aids and office supplies, whiteboard markers have become new teaching and office tools in recent years due to their advantages of smooth writing, convenient use, no dust, wipeability, and relative environmental protection and safety. Whiteboard markers mainly include water-based whiteboard markers and solvent-based whiteboard markers. [0003] Solvent-based whiteboard pen ink, due to the strong solubility of the solvent, the ink will seep into the board surface and cause stains after long-term use. It is difficult to clean the board surface. Daily maintenance requires special cleaning agents. The maintenance steps are cumbersome and the cost is high. [0004] Water-based whiteboard pen ink uses...
