Preparation method of cobaltous oxide nanoparticle doped rosinyl thermal polymerization anticorrosion film with high pitting corrosion potential

The invention discloses a preparation method of a cobaltous oxide nanoparticle doped rosinyl thermal polymerization anticorrosion film with the high pitting corrosion potential. Acrylamide is taken asa monomer, azodiisobutyronitrile is taken as an initiator, cobaltous oxide nanoparticles are taken as a doping agent, acrylpimaric acid (ethanediamine) amide is taken as a crosslinking agent, the cobaltous oxide nanoparticle doped rosinyl thermal polymerization anticorrosion film with the high pitting corrosion potential is prepared through a thermal polymerization method, a film layer has the high pitting corrosion potential and is good in pitting corrosion resisting performance, simple and practical, and the defect of low corrosion potential of former anticorrosion film layers is overcome.The film layer can be applied to anticorrosion engineering of metal parts of electrical devices such as air conditioners, electric water heaters, air conditioners and refrigerators, and mechanical devices such as tractors and
