preparation example Construction
[0036] Such as figure 1 Shown, the preparation method of the color-changing ink of an embodiment, comprises the following steps:
[0037] The color-changing ink is obtained by dissolving 20-50 parts of space-forming materials and 1-10 parts of guest molecules in 20-60 parts of solvent.
[0038] Specifically, the above steps include step S110 and step S130:
[0039] Step S110: Dissolving 20-50 parts of space-forming materials in 20-60 parts of solvent to obtain the first mixture;
[0040] Step S130: adding 1-10 parts of guest molecules into the first mixture, mixing and dissolving to obtain the color-changing ink.
[0041] In some embodiments, in the above step of obtaining the color-changing ink, that is, after step S110 and before step S130, it also includes step S120: adding 5 parts to 30 parts of filler material to the first mixture dissolved step. It should be noted that, in some embodiments, the above-mentioned fillers can be generated internally by the addition and e...
Embodiment 1
[0052] The preparation steps of the color-changing ink of the present embodiment are as follows:
[0053] (1) Take 20 parts of polyvinyl butyral, add it into 30 parts of isopropanol and dissolve it to obtain the first mixture.
[0054] (2) Get 5 parts of stearic acid and dissolve in the above-mentioned first mixture.
[0055] (3) Finally, add 1 part of iodine simple substance to the above-mentioned first mixture for mixing and dissolving to obtain the color-changing ink.
[0056] The initial state of the color-changing ink prepared in Example 1 is orange. After the ink solvent is dried, polyvinyl butyral, stearic acid and iodine element together form an inclusion compound, which is green. With the escape of iodine element, the ink gradually changes from Green changes to blue and finally to transparent color. Experiments have shown that when the ink layer thickness of the above-mentioned color-changing ink is 0.01 mm, the color-changing cycle of the color-changing ink layer i...
Embodiment 2
[0058] The preparation steps of the color-changing ink of the present embodiment are as follows:
[0059] (1) Take 30 parts of polyvinyl butyral and dissolve it in 30 parts of isopropanol to obtain the first mixture.
[0060] (2) Take 10 parts of oleic acid and dissolve in the above-mentioned first mixture.
[0061] (3) Finally, add 3 parts of simple iodine to the above-mentioned first mixture for mixing and dissolving to obtain the color-changing ink.
[0062] The initial state of the color-changing ink prepared in Example 2 is orange. After the ink solvent is dried, polyvinyl butyral, oleic acid and iodine element together form an inclusion compound, which is green. With the escape of iodine element, the ink gradually changes from green to green. turns blue and eventually becomes transparent. Experiments have shown that when the ink layer thickness of the above-mentioned color-changing ink is 0.05mm, the color-changing cycle of the color-changing ink layer is 15 days in an...
