[0023] A preparation method of digital inkjet printing thermal transfer printing film comprises the following steps:
[0024] 1. Mix carboxymethyl cellulose (CMC) and water at a mass ratio of 2:10. The water temperature is 70-90°C. Stir mechanically to form a viscous liquid, and let it cool down;
[0025] 2. Mix titanium dioxide and normal temperature water at a mass ratio of 4:10, mechanically grind for 15-25 minutes to make a liquid;
[0026] 3. Mix polyvinyl alcohol (BP-24) with water at a mass ratio of 3:10, soak for 2-3 hours at 100°C, stir mechanically and let it cool down;
[0027] 4. Grind the starch mechanically for 15-25 minutes, then add room temperature water to mix, the mass ratio of starch to water is 4:10, stir until evenly mixed;
[0028] 5. Mix the liquid made in steps 1-4 with the silicone defoamer, the mass percentage is: carboxymethyl cellulose solution: titanium dioxide solution: starch solution: polyvinyl alcohol solution: silicone defoamer = 70% : 7%: ...
