| 中文摘要: |
| 目的 提高压载水舱环氧涂料的耐阴极剥离性能。方法 以双酚A型环氧树脂、酚醛环氧树脂、C9石油树脂和双酚F型环氧树脂为涂料的主要成膜树脂，采用四因素四水平的正交试验，对四种树脂的用量进行优化。固化剂采用聚酰胺固化剂和改性酚醛胺固化剂进行混合，以获得良好的物理化学性能。对涂料的颜基比及助剂进行了分析研究，以确定涂料各组分的用量。结果 通过四因素四水平的正交试验，确定了涂料四种树脂的用量。当聚酰胺固化剂和改性酚醛胺固化剂的混合比例为2:1时，涂料具有较佳的抗阴极剥离性能。通过对颜填料不同颜基比（0.75:1~1.5:1）的研究，当涂料的颜基比为1:1时，涂料的耐阴极剥离性能最好。结论 通过对涂料的成膜树脂、固化剂及颜基比的研究，制备的压载水舱环氧涂料具有优异的耐阴极剥离性能及良好的耐海水性、耐盐雾性及抗腐蚀蔓延性等性能，能够满足船舶压载舱的防腐需求。 |

| The work aims to improve the cathodic disbonding resistance of ballast tank epoxy paint. With bisphenol A epoxy resin, novolac epoxy resin, C9 petroleum resin and bisphenol F epoxy resin as main film-forming resins of the paint, additive amount of the four resins were optimized by performing four factors at four levels orthogonal test. The mixed curing agent consisting of polyamide and modified phenolic amine exhibited excellent physical and chemical properties. Pigment binder ratio and additives of the paint were analyzed and studied to determine additive amount of each coating constituent. When mixing ratio of polyamide curing agent and modified phenolic amine curing agent was 2:1, the paint exhibited better cathodic disbonding resistance. Based upon study on different pigment binder ratios (0.75:1~1.5:1), the paint exhibited the best cathodic disbonding resistance when the pigment binder ratio was 1:1. Based upon study on film-forming resins, curing agents and pigment binder ratios, the prepared ballast tank epoxy paint exhibits excellent cathodic disbonding resistance, and can meet the anticorrosion demand of ship ballast tank. The high solid epoxy paint developed for ship ballast tank has excellent cathodic disbonding resistance, sea water resistance, salt fog resistance and corrosion creeping resistance. |
