Abstract Eucommia ulmoides gum (EUG) was epoxidized by emulsion method, the obtained epoxidized eucommia ulmoides gum (EEUG) and epoxy resin (E44) were blended as a film-forming substance, and an anti-corrosive coating was prepared by using ethyl acetate as a solvent; the coating was carried out by changing the epoxidizing degree of eucommia ulmoides gum and the matrix ratio (EEUG/E44), and testing by infrared spectroscopy, nuclear magnetic resonance, electrochemical impedance, adhesion test and salt spray corrosion test. Through infrared spectroscopy and nuclear magnetic resonance analysis, it could be obtained that EEUG was successfully prepared and its epoxidation was calculated. In electrochemical impedance analysis, adhesion analysis, coating morphology analysis and salt spray resistance analysis, it was known that the epoxy eucommia rubber coating with low epoxidation had better adhesion effect and better corrosion resistance. It could be concluded that proper addition of EEUG could enhance the interaction between coating and metal matrix, and effectively retarded the corrosion of coating. The optimum ratio of film-forming material was 0.5/1 (EEUG/E44).

Key words： eucommia ulmoides gum epoxidation epoxy resin anticorrosion coating
