摘要
环氧涂层是一种重要的有机涂层,因其优异的绝缘特性和粘附力,被广泛应用于金属构件的腐蚀防护中。为了提高有机涂层的耐蚀性能,通过添加填料对其进行改性。根据金属表面有机涂层的防护机理将其分为物理屏障涂层、自修复涂层,以及兼具物理阻隔作用和自修复性的双功能涂层,并且对其发展现状进行了总结,详细阐述了每类涂层的防护机制、研究进展及优劣势,最后指出研发双功能环氧涂层是大幅度提升涂层服役寿命的潜在途径,也是防腐涂层未来的发展趋势和前沿课题。
Organic coatings,such as epoxy coatings,have become an important strategy for corrosion protection of metal components due to their excellent insulation and adhesion,especially when fillers are added,which can greatly improve their corrosion resistance.In this paper,the development of organic anti-corrosion coatings on metal surfaces is reviewed according to their protective mechanisms,which can be divided into physical barrier coatings,self-repairing coatings,and bi-functional coatings that have both physical barrier and self-repairing functions.The protective mechanisms,current research progress,advantages and disadvantages of each type of coating are reviewed in detail.It is also pointed out that the development of bifunctional epoxy coatings is a potential way to significantly improve the service life of coatings.This is also the development trend and frontier subject of anti-corrosion coating in the future.
