The invention specifically relates to an improved preparation method for a zinc/copper acrylate resin, which belongs to the technical field of marine anti-fouling paints. The preparation method comprises the following steps : with a mixed system of water and an organic solvent as a disperse medium, reacting a metal salt solution with aqueous alkali to produce zinc/copper hydroxide, fully dispersing the zinc/copper hydroxide in a dispersant and then carrying out filtering and drying so as to obtain high-dispersibility zinc/copper hydroxide; subjecting soft and hard monomers of acrylic acid to free radical polymerization under the action of an initiator at a constant temperature so as to produce an acrylic prepolymer containing a carboxyl group; and reacting the acrylic prepolymer obtained in the previous step with the dispersed zinc/copper hydroxide under the action of an organic acid at a constant temperature so as to prepare the zinc/copper acrylate resin with hydrolysis characteristics. According to the invention, the zinc/copper hydroxide prepared in the invention has good dispersibility and no agglomeration and needs short reaction time during reaction with the acrylic prepolymer, so cost is low, and original equipment does not need to be improved.
