Anti-after-tack elastic acrylic aqueous dispersion and preparation method thereof

The invention discloses an anti-after-tack elastic acrylic aqueous dispersion and a preparation method thereof. The anti-after-tack elastic acrylic aqueous dispersion is prepared from a nano-silica hybridized acrylic emulsion with the high softening point and a nano-silica hybridized acrylic emulsion with the low softening point under the action of a siloxane coupling agent through compounding. The prepared anti-after-tack elastic acrylic aqueous dispersion has good flexibility, anti-after-tackiness and hardness.
