研究了添加第二代无毒活性磷酸盐SAPP和SRPP的水性马来酸酐共聚物涂层的防腐蚀性能. 通过盐雾试验、电化学阻抗谱(EIS)和浸泡试验研究这两种防锈颜料分散在水性马来酸酐共聚物涂层后对基材的防腐性能. 结果表明两种防锈颜料加入涂层后都能明显提高涂层的防腐蚀性能, 且SRPP颜料的防腐蚀效果优于SAPP颜料.
Corrosion protection performance of maleic anhydride copolymer water-borne polyurethane coatings incorporated with pigments SAPP and SRPP, which are the so called second-generation nontoxic anti-corrosion pigments, was investigated by salt spray test, electrochemical impedance spectroscopy (EIS) measurement and immersion test. The results showed that the incorporation of SAPP and SRPP to the coating led to a remarkable improvement on its anticorrosive properties, and the corrosion resistance of SRPP was superior to that of SAPP.
