Embodiment 1
[0037] This example provides a method for preparing a reversible thermochromic ink. The raw material components used are as follows: thermochromic powder: 23%, modified malic acid resin: 22%, deionized water: 5%, isopropanol: 40% %, ethyl acetate: 5%, SRE-4190 hyperdispersant: 3%, 2-ethylhexanol: 2%; the specific steps of the preparation method are as follows:
[0038] S1. Preparation of thermochromic powder: mix crystal violet lactone, boric acid, and cetyl alcohol in a mass ratio of 1:15:50, stir with a magnetic stirrer, stir evenly, and put it in a water bath at 80°C for 3 hours to react. After completion, dry in a constant temperature drying oven at 40°C, ball mill and sieve to obtain a thermochromic powder with a fineness of 800 μm;
[0039] S2. Prepare solvent: add the modified malic acid resin to isopropanol and deionized water, stir and dissolve, add half of 2-ethylhexanol and stir evenly;
[0040] S3. Stir once: put the thermochromic powder prepared in the step into ...
Embodiment 2
[0043] This example provides a method for preparing a reversible thermochromic ink. The raw material components used are as follows: thermochromic powder: 20%, modified malic acid resin: 24%, deionized water: 8%, isopropanol: 40% %, ethyl acetate: 6%, SRE-4190 hyperdispersant: 1%, 2-ethylhexanol: 1%; the specific steps of the preparation method are as follows:
[0044] S1. Preparation of thermochromic powder: mix crystal violet lactone, boric acid, and cetyl alcohol in a mass ratio of 5:20:45, stir with a magnetic stirrer, stir evenly, and put it in a 95°C water bath for 4 hours to react. After completion, dry in a constant temperature drying oven at 40°C, ball mill and sieve to obtain a thermochromic powder with a fineness of 700 μm;
[0045] S2. Prepare the solvent: add the modified malic acid resin to isopropanol and deionized water, stir and dissolve, add ethyl acetate and 0.5% 2-ethylhexanol and stir evenly;
[0046] S3. Stir once: put the thermochromic powder prepared i...
Embodiment 3
[0049]This example provides a method for preparing a reversible thermochromic ink. The raw material components used are as follows: thermochromic powder: 20%, modified malic acid resin: 20%, deionized water: 4%, isopropanol: 45% %, ethyl acetate: 7%, SRE-4190 hyperdispersant: 2%, 2-ethylhexanol: 2%; the specific steps of the preparation method are as follows:
[0050] S1. Preparation of thermochromic powder: mix crystal violet lactone, boric acid, and cetyl alcohol in a mass ratio of 1:20:50, stir with a magnetic stirrer, stir evenly, and put it in a 90°C water bath for 5 hours to react. After completion, dry in a constant temperature drying oven at 40°C, ball mill and sieve to obtain a thermochromic powder with a fineness of 700 μm;
[0051] S2. Prepare the solvent: add the modified malic acid resin to isopropanol, stir and dissolve, add half of 2-ethylhexanol and stir evenly;
[0052] S3. Stir once: put the thermochromic powder prepared in the step into the solution in step...
