摘要 采用乳液法对杜仲胶(EUG)进行环氧化,将得到的环氧杜仲胶(EEUG)与环氧树脂(E44)共混作为成膜物质,以乙酸乙酯为溶剂制作防腐涂料;通过改变杜仲胶环氧度以及基体配比(EEUG/E44)的方式进行涂敷,并对其进行红外光谱、核磁共振、电化学阻抗、附着力测试以及盐雾腐蚀试验等一系列表征。红外光谱分析和核磁共振分析表明成功制得了EEUG并计算出其环氧度;电化学阻抗分析、附着力分析、涂层形貌分析和耐盐雾分析表明使用环氧度低的EEUG涂层附着效果更佳,防腐性能更好。结果表明:适当添加EEUG可以增强涂层与金属基体的作用力并能有效延缓涂层的腐蚀;成膜物质的最佳配比为0.5/1(EEUG/E44)。

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).
