| description | The invention discloses a preparation method for an acrylate-modified epoxy resin cathode electrophoresis emulsion. The method adopts a monoprotic organic acid containing a double bond and a biproticorganic acid containing a double bond or/and an acid anhydride to react with epoxy resin, double bonds are introduced into a main chain of the epoxy resin, acrylic resin is grafted into the epoxy resin by utilizing copolymerization of the double bonds and an acrylate monomer, more acrylic resin can be introduced onto the main chain of the epoxy resin, adjustment and control of an introduction amount of the acrylate monomer are achieved through control of the content of the double bonds, and a molecular weight of the main epoxy resin is adjusted through a ratio of carboxyl to epoxy groups; themain body of the prepared product is epoxy resin, so that good anticorrosive performance of a paint film is guaranteed; and when the epoxy resin is aminated, two different organic amines are added step by step for a reaction, |
