研究了超细玻璃纤维对双酚A型（E44）和双酚F型（DER354）环氧树脂涂层体系力学性能和耐腐蚀性能的影响。通过盐雾试验和电化学阻抗谱（EIS）研究了涂层的耐腐蚀性。结果表明在双酚A和双酚F环氧树脂组成的涂料体系中，双酚A环氧树脂能够提高涂层的硬度，而双酚 F环氧树脂能够提高涂层的耐腐蚀性。

This paper focuses on the influence of ultra-fine glass fiber on the coating properties. Diglycidyl ether of bisphenol-A and diglycidyl ether of bisphenol-F epoxy resins were used as film former. Salt spray test and electrochemical impedance spectroscopy (EIS) were employed to characterize the anticorrosion properties of the coatings. Experimental results indicate that the diglycidyl ether of bisphenol-A epoxy resin can improve the coating hardness, while the diglycidyl ether of bisphenol-F epoxy resin has better anticorrosion properties.
