摘　　要：聚酰胺与酚醛胺的复配,所得固化剂固化速度快,综合性能好。颜料、填料能够提高涂料的防腐性、机械性能、附着力等,通过考察颜基比对涂层性能的影响,得出压载舱涂料的颜基比在1.5～2.0之间比较合适。由触变指数来评价触变剂的防沉抗流挂性能,筛选出G-1958有机喷润土和202/805气相二氧化硅。从破泡抑泡性、流平性和涂膜外观的效果来看,Efka2722消泡效果比较好,而且有一定的流平作用。以液体环氧树脂、改性树脂R为基料,聚酰胺和酚醛胺为固化剂,合理选用触变剂、消泡剂以及颜填料,所制得的改性环氧压载舱涂料柔韧性好,抗阴极剥离、附着能力好,防腐性能强。模拟压载舱和冷凝舱的试验表明,其性能已达到《所有类型船舶专用海水压载舱和散货船双舷侧处所保护涂层性能标准》附件1的技术要求。The blended curing agent of polyamide and phenolic amine was featured by its fast dry and good overall performance in ballast tank coatings. The pigments and fillers in coatings could improve the cor- rosion resintanee, mechanical properties and adhesion. The P/B ratio was determined at 1.5 - 2.0 based on the test result of relationship between P/B ratio and film performance. The thixotropic agent, organic benton- ire G - 1958, fumed silica 202/805 were evaluated by thixotropic index and sag resistance. Defoamer Efa- ka2722 showed strong anti -toaming with foam suppression, leveling and appearance improvement. The modified epoxy -resin coatings was prepared by using liquid epoxy resin, modification resin R, polyamide/ phenolic amine blended curing agent, thixotropic agents, efficient defoamers and fillers, which provided the modified epoxy ballast tank coatings excellent corrosion resistance, good flexibility, cathodic disbondment re- sistance, good wetting and adhesion on shop- primer. Test of simulated ballast tank condition ＆ condensa- tion chanber tesl have showed that performance of the modified epoxy - resin ballast tank coatings could meet technical requirements of PSPC appendix 1.
