Abstract

The invention provides quick-setting acrylic latex and a preparation method thereof, the pH of the quick-setting acrylic latex is not less than 9, and the quick-setting acrylic latex comprises volatile alkali; wherein the quick-setting acrylic latex is prepared from the following raw materials in parts by mass: 0 to 19.713 parts of styrene, 0 to 18.144 parts of methyl methacrylate, 27.2 to 33.67 parts of alkyl acrylate, 1.623 to 3.116 parts of a functional monomer and 1.495 to 1.498 parts of a cationic monomer; the functional monomer is prepared from at least one of methacrylic acid, methacrylamide, methacrylic acid-2-hydroxyethyl ester, trimethylolpropane trimethacrylate and vinyl trimethoxy silane; the cationic monomer is prepared from at least one of N-(3-dimethylaminopropyl) methacrylamide and methacrylic acid N, N-dimethylaminoethyl ester. The acrylic latex provided by the invention has a quick-setting effect.
