本文利用电化学方法研究了在油漆涂层中添加三聚磷酸钛和磁性氧化铁对金属防护性能的影响。结果表明,三聚磷酸钛作为活性防锈颜料,添加在涂层中能够极大地改善涂层的防护性能,磁性氧化铁亦不失为一种较好的防锈颜料,但性能不及三聚磷酸钛。同时亦探讨了这两种颜料的可能防锈机理。 In this paper, electrochemical methods were used to study the effect of adding trimethylammonium phosphate and magnetic iron oxide on the protective properties of metals in paint coatings. The results show that the addition of titanium triphosphate as active anticorrosive pigment can greatly improve the protective performance of the coating. Magnetic iron oxide is also a good anti-rust pigment, but its performance is inferior to that of titanium triphosphate. At the same time also discussed the possible anti-rust mechanism of these two pigments.
