The invention relates to the technical field of
polymer microspheres, and discloses a
polymer microsphere as well as a preparation method and application thereof. The method comprises the following steps: (1), stirring and mixing
silicon-containing
methylamine, chloropropene and absolute ethyl
alcohol, then carrying out heating reaction in a
nitrogen atmosphere, and then carrying out rotary
evaporation, cooling, washing, recrystallization, reduced-pressure suction
filtration and
vacuum drying to obtain a
silicon cationic
monomer; (2), adding the hydrophilic white
carbon black into an
ethanol water solution, performing stirring and dispersing, adding a
silane coupling agent in a stirring state, performing heating, carrying out condensation
reflux, performing cooling to
room temperature, stopping stirring, performing washing, and then performing
drying to obtain modified white
carbon black; and (3), mixing
styrene, N-tert-butyl
acrylamide, a
silicon cationic
monomer, the modified white
carbon black, a cross-linking agent and 2, 2'-azo (2-methyl propyl
amidine) dihydrochloride, and adding water for reaction. The
polymer microsphere prepared by the method can be combined with
gardenia yellow dye, so that the anti-aging performance of the dye is greatly improved, and a series of indexes after
dyeing are also improved.
