The present application relates to the technical field of coatings, and provides a polyacrylate emulsion and a preparation method thereof. The preparation raw materials of the polyacrylate emulsion provided by the application include: 20-35 parts of (meth)acrylic acid C1-C8 alkyl ester monomers, (meth)acrylic acid C10-C18 alkyl ester monomers 2-6 parts parts, 0-10 parts of vinyl monomers, 0.2-3 parts of carboxyl monomers, 0.05-3 parts of multifunctional cross-linking monomers, 0.1-3 parts of room temperature self-crosslinking monomers, 0.2-2 parts of reactive emulsifiers , 0.05-0.5 part of ammonium zirconium carbonate, 0.03-0.5 part of initiator, 0.1-0.5 part of buffer, 0.05-0.2 part of chain transfer agent, 0.3-1 part of pH adjuster, 0-1 part of auxiliary, 40-60 part of water share. The synergistic effect of the above components endows the polyacrylate emulsion with good water whitening resistance, and effectively solves the problem of whitening and foaming of the polyacrylate coating film after soaking in water. |
