| 中文摘要: |
| 目的 通过在有机防腐涂层中添加小粒径的自修复微胶囊，增强防腐涂层的自修复能力，提高碳钢的耐腐蚀性能。方法 通过乳液聚合法，采用桐油和金属缓蚀剂作为囊芯，分别合成得到了粒径均一的单组分和双组分自修复胶囊，均匀分散于防腐涂层中，获得自修复涂层。结果 SEM和热重分析显示，合成的单组分和双组分自修复微胶囊的平均粒径在3 μm左右，囊芯包覆率分别达到48%和49%。人为破损涂层的中性盐雾试验和浸泡试验表明，在囊芯中桐油和金属缓蚀剂的比例为5∶1且防腐涂层中微胶囊含量为10%的条件下，经历110 h中性盐雾试验后，防腐涂层划痕处仍旧保持完整，未出现鼓泡和腐蚀现象。同时，浸泡675 h后，自修复涂层仍然保持较高的低频阻抗模值，表明此时涂层的耐蚀性最佳。结论 含有双组分微胶囊的自修复涂层具有较好的自修复能力，可以较好地阻碍腐蚀环境侵蚀，起到长期保护金属基体材料的作用。 |
| 英文摘要: |
| The emulsion polymerization method with tung oil and inhibitor serving as the capsule core is used to synthetize the self-healing microcapsules. And a certain amount of self-healing microcapsules are added into the anticorrosive coating in order to improve the self-healing ability of coating and to enhance the anticorrosion performance of carbon steels. Analysis results of SEM and thermogravimetry show that self-healing microcapsules possess a diameter of ~3 μm and that the core coverage percent reaches 48%. Experimental results of neutral salt spray tests and immersion tests show that the organic coating presents an optimal anticorrosive ability accompanying with the best self-healing action when the content of microcapsules in the coating reaches 10% and the ratio of tung oil and inhibitor in the core is 5∶1. The organic anticorrosive coating with two- component microcapsules has the satisfactory self-healing activity, and has long-term protective effects on the metal materials. |
