Embodiment Construction
[0029] The method for preparing a tooth whitening compound with temperature-sensitive magnetic targeting provided by the embodiment of the present invention comprises the steps of:
[0030] 101. Preparation of oleic acid modified Fe3 o 4 Nano magnetic particles;
[0031] 102. With the Fe 3 o 4 Composite A is prepared by using nano-magnetic particles as the core and covering N-isopropylacrylamide with miniemulsion polymerization;
[0032] 103. Mix and stir the compound A and carbamide peroxide for 2-4 hours at room temperature, then centrifuge, discard the supernatant to obtain the temperature-sensitive magnetically targeted tooth whitening compound.
[0033] Specifically, step 101 includes: taking FeCl 2 and FeC1 3 Dissolve at least one of the substances in deionized water, for example, take 150-200g FeCl 2 and FeC1 3 Add the mixture to 1L of deionized water and stir evenly. After heating to 60-70°C, add 30mL of ammonia water and 20mL of oleic acid, then keep stirring a...
