Embodiment 1
[0022] This low-temperature organic irreversible thermochromic coating is prepared according to the following component ratios:
[0023]
[0024] The preparation method of this low-temperature organic irreversible thermochromic coating is:
[0025] (1) Disperse talcum powder and organic reversible thermochromic material in a high-speed disperser to obtain component A;
[0026] (2) Add a certain amount of water-based epoxy resin to component A obtained in step (1), add modifier KH-560 and other additives, stir and mix at high speed, take out the coating mixture, and grind it in a grinder Fine, use a 100-mesh fine sieve to filter out the insoluble solid impurities therein to obtain a color-changing paint.
[0027] (3) The obtained discoloration coating is coated on the pre-treated tinplate sheet, and the discoloration performance and basic performance of the coating are tested.
[0028] Embodiment 1 performance measurement result is as following table:
[0029]
