摘要： 以聚醚砜酮（PPESK）为基料，分别以云母氧化铁、超磷锌白、磷铁粉为防腐填料，制备了耐高温防腐涂料。研究了填料类型对涂层耐高温防腐性能的影响。结果显示：以云母氧化铁为防腐填料制备的 PPESK耐高温防腐涂料具有很好的耐氙灯老化及耐高温性能，耐氙灯老化时间大于42d，可耐 500℃高温，耐急冷急热性能优异；以磷铁粉为防腐填料制备的PPESK耐高温防腐涂料，耐盐雾、耐介质性能优异，耐盐雾时间大于 42d，对各种化学介质均有很好的耐性；而以超磷锌白制备的涂料，各项性能欠佳。

Abstract: The title coating was prepared by use of poly(phthaalazinone ether sulfone ketone )(PPESK)as binders and the iron phosphate, the micaceous iron oxide zinc phosphorus as fillers respectively. Three kinds of PPESK high temperature resistant and anticorrosive coating were prepared. The effect of anticorrosive fillers,' type on the corrosion protective properties of the coatings were studied. The results indicated that the coating with micaceous iron oxide showed excellent xenon lamp aging resistance and high temperature resistance,the time of xenon lamp aging resistance was over 42 days and the temperature was 500 ℃ as well as good heat shock resistance. The coating with iron phosphate showed excellent salt fog resistance and chemical resistance over 42 days. But the coating with zinc phosphorus, didn't show good performance.
