Abstract

The invention discloses a method for preparing copper (zinc) acrylate resin. The method is characterized by comprising the following steps: firstly, synthesizing a polyacrylic resin solution containing carboxyl groups, and neutralizing the solution using an aqueous solution of sodium hydroxide to obtain a sodium polyacrylate resin solution; preparing an organic acid copper (zinc) chloride intermediate; carrying out ion exchange reaction to generate copper (zinc) polyacrylate resin; washing the copper (zinc) polyacrylate resin to remove impurity; and dehydrating the washed resin by distilling to finally obtain the copper (zinc) polyacrylate resin solution. The copper (zinc) polyacrylate resin synthesized by the method is high in metal ion content, low in viscosity and conductive to preparation of a self-polishing antifouling coating.

Description

technical field [0001] The present invention relates to the manufacture of the macromolecular material in the field of chemical industry, specifically, relate to a kind of synthetic method of resin material, more specifically, relate to a kind of synthetic method of copper acrylate and zinc acrylate resin, this kind of resin can be used for Manufacture of self-polishing antifouling coatings. Background technique [0002] Resins used in environmentally friendly self-polishing antifouling coatings are typically hydrolyzable copper polyacrylate or zinc polyacrylate resins. When this kind of coating is used, after being hydrolyzed with water, copper (zinc) ions dissolve into the water to act as an antifouling agent, leaving hydrophilic carboxyl groups in the resin, so that the polyacrylic resin swells or even dissolves in water. It is washed away by the water flow to form a smooth surface and achieve the effect of self-polishing. At the same time, the antifouling agent in the ...
