The invention discloses a preparation method of a
montmorillonite-modified crosslinked
acrylate-hybridized core-shell
emulsion. The preparation method of the
montmorillonite-modified crosslinked
acrylate-hybridized core-shell
emulsion comprises the following steps: dispersing
sodium-based
montmorillonite, an emulsifying agent and a
buffering agent into water; stirring to obtain a
sodium-based montmorillonite suspension; adding a core
monomer mixture and an initiating agent solution into the
sodium-based montmorillonite suspension, and preserving heat for 0.5 hours to obtain a seed
emulsion; dripping the remaining core
monomer mixture into the seed emulsion, and preserving heat for 1 hour to obtain a
deep blue core emulsion; and adding the initiating agent solution and a shell
monomer mixture into core emulsion, preserving heat for 2 hours and regulating pH value to obtain the opalescent bluish montmorillonite-modified crosslinked
acrylate-hybridized core-shell emulsion. The prepared montmorillonite-modified crosslinked acrylate-hybridized core-shell emulsion is good in
water resistance and
heat resistance of a
coating, adjustable in gloss of a latex film, free of
organic solvent, environment-friendly, relatively high in
solid content (32 to 45%), relatively small in particle size, bluish, high in stability (storage stability is more than six months) and good in a film-forming property at
room temperature.
