The invention discloses an anionic oxidized Fischer-Tropsch
wax nano-
emulsion and a preparation method thereof, and belongs to the technical field of
emulsion preparation. The
emulsion is prepared from 20%-40% of oxidized Fischer-Tropsch
wax, 0.5%-1.0% of
sodium hexadecyl sulfonate, 0.5%-1.0% of
sodium hexadecyl
benzene sulfonate, 0.5%-2.0% of
potassium cocoate, 0.2%-0.4% of
sodium hydroxide and the balance deionized water. Wherein the
acid value of the oxidized Fischer-Tropsch
wax is 10-20 mg KOH / g, and the drop
melting point is 60-90 DEG C. According to the invention, a pure anionic emulsifier compounding
system is adopted, the blank of anionic Fischer-Tropsch wax emulsion is filled, the emulsifier dosage is low, the emulsion particle size is 300-500nm, the
dispersity and centrifugal and thermal
cycling stability are excellent, the production process is simple and easy to amplify, and the preparation method can be widely applied to the fields of
printing ink, coatings,
hot melt adhesives and the like.
