Embodiment 1
[0044] Uniformly disperse zirconium phosphate with a particle size of 1.0 μm and a mass of 15 g in tetrahydrofuran solvent to obtain a zirconium phosphate dispersion; at the same time, the reaction reagents (phosphazene, 4,4'-biphenylmethylene diisocyanate, ethyl The molar ratio of diamine is 1:2:4) added to the above zirconium phosphate dispersion, and the ratio of the added reaction reagent to the molar number of zirconium phosphate is controlled to be 0.2:1, and the reaction temperature is raised to 120°C, mechanically stirred and reflux, the stirring rate is controlled at 200 rpm, and the reaction time is controlled at 24 hours. After the reaction is completed, it is washed alternately with acetone and deionized water for 2 to 3 times, and then freeze-dried at -40°C for 24 hours to obtain microcapsules. zirconium phosphate.
