Abstract:

The title self-stratifying hybrid cathodic electrodeposition coatings consisteted of self crosslinkable acrylic resin and epoxy resin were designed and synthesized. The effects of blocking agent and temperature of grafting reaction on the reaction process and properties of product were studied. And the effects of parameters of electrophoretic technology on the properties of paint films were also investigated systematically.The FTIR tests showed that the self-stratifying structure was formed in the hybrid coatings film and the film can provide good weather-resistance, good corrosion resistance and decorative performance and realized primer-topcoat in one coat.
