The invention discloses a preparation method of an organosilicon modified matte cathodic electrophoresis resin and a cathodic matte electrophoresis emulsion prepared. The mixture of styrene, methyl methacrylate, butyl acrylate, isooctyl methacrylate, hydroxyethyl acrylate, dimethylaminoethyl methacrylate, silicone monomer and initiator was added dropwise, and the dropwise addition was controlled. The time is 4h, and the dropwise addition is completed for 1h; the addition of the initiator is continued, the dropwise addition time is controlled to 1h, and the dropwise addition is completed for 1h; the solvent is added, mixed and stirred evenly, and the organic material can be obtained by cooling and discharging. Silicon modified matte cathodic electrophoresis resin; and use it as raw material to prepare cathodic matte electrophoresis emulsion and bath, the obtained cathodic electrophoresis emulsion has good storage stability, and the paint film obtained by electrophoresis in the bath is resistant to salt spray, Sharp edge corrosion performance and cupping performance are better. |
