耐高温、盐和水蒸气腐蚀自修复涂料及其制备方法与应用
摘要：
本发明涉及金属构件的耐高温、盐和水蒸气防腐蚀技术，具体为一种耐高温、盐和水蒸气腐蚀自修复涂料及其制备方法与应用，属于精细化工领域。按质量份数计，有机硅树脂10～80份，耐高温填料1～50份，自修复填料1～50份，防沉剂2～70份，溶剂20～80份，固化剂与有机硅树脂的质量比例为1:(3～10)。按比例称取耐高温、盐和水蒸气腐蚀自修复涂料各组分并混合均匀后，采用喷涂、刷涂或浸涂的方式，在经过喷砂或打磨处理的金属构件表面制备涂层，在洁净环境下进行室温固化24h，即得到耐高温、盐和水蒸气腐蚀自修复涂层。本发明涂料耐高温、盐和水蒸气腐蚀性能优良，能有效解决在高温、盐和水蒸气环境中的氧化和腐蚀问题。
摘要（英）：

The invention relates to the technology of high temperature resistance, salt and water vapor corrosion prevention of metal components, in particular, relates to a self-repairing coating resistant to high temperature, salt and water vapor corrosion and a preparation method and an application thereof, and belongs to the field of fine chemical engineering. The coating comprises, in parts by mass, 10-80 parts of organicsilicon resin, 1-50 parts of a high temperature resistant filler, 1-50 parts of a self-repairing filler, 2-70 parts of an anti-settling agent, and 20-80 parts of a solvent, whereinthe mass ratio of a curing agent to the organicsilicon resin is 1:(3-10). The components of the self-repairing coating resistant to high temperature, salt and water vapor corrosion are weighed in proportion and mixed evenly, a coating layer is prepared on the surface of a metal component after sand blasting or grinding by a method of spraying, brushing or dip coating and is cured at room temperature for 24 h in a clean environment to obtain a self-repairing coating layer resistant to high temperature, salt and water vapor corrosion. The coating has excellent resistance to high temperature, salt and water vapor corrosion, and can effectively solve the oxidation and corrosion problems in high temperature, salt and water vapor environments.
