摘要：以季戊四醇磷酸酯（PEPA）与可膨胀石墨（EG）作为复合填料，添加到水性环氧树脂(EP)中制备出
PEPA-EG/EP 复合涂料。通过耐火极限分析、热失重分析、极限氧指数测试、垂直燃烧测试、残炭扫描电镜分
析、残炭红外分析、电化学实验和附着力实验，考察了不同质量配比的复合填料对 PEPA-EG/EP 复合涂料阻燃
性能和防腐性能的影响。结果表明：当复合填料与水性环氧树脂的质量比为 15∶100 时，涂料具有最佳的阻燃
性能和防腐性能，其钢片背温达到 500 ℃的时间是 38 min，极限氧指数达到 27.2%，垂直燃烧等级达到 V-1 级，

Abstract: Pentaerythritol phosphate (PEPA) and expandable graphite (EG) as composite fillers were added
into waterborne epoxy resin (EP) to prepare PEPA-EG/EP composite coatings. The effect of mass ratio of
composite filler on the flame retardancy and corrosion resistance of PEPA-EG/EP composite coating was
investigated by fire resistance limit analysis, thermogravimetric analysis, limiting oxygen index test,
vertical burning test, residual carbon scanning electron microscopy, residual carbon infrared analysis,
electrochemical impedance spectroscopy and adhesion experiment. The results show that when the mass
ratio of composite filler to waterborne epoxy resin is 15∶100, the prepared composite coating has the best
flame retardant properties and corrosion resistance. The time when the back temperature of steel sheet
reaches 500 ℃ is 38 min, the limiting oxygen index is 27.2%, the vertical combustion performance
reaches V-1 level, the residual carbon amount increases to 27.79% at 800 ℃, and the composite coating

has the highest impedance value (9.2410 cm ) during electrochemical impedance spectroscopy testing
after 480 hours of immersing.
