| 摘 要： | 利用"活性"与"非活性"硅烷化学改性环氧涂层以提高其耐蚀性."活性"硅烷指含有可以与环氧树脂的环氧端基发生开环反应官能团的硅烷,通常为氨基硅烷;"非活性"硅烷指不与环氧端基发生反应,但在有机锡催化剂存在下可与环氧树脂骨架上的羟基发生缩合反应的硅烷.红外光谱显示,两类硅烷均可成功接枝在环氧树脂上.电化学阻抗谱(EIS)和加速腐蚀试验(Machu试验)测试表明,经硅烷化学改性后的环氧涂层均能提高其耐蚀性能.

| Abstract: | The improvement of corrosion performance of epoxy coatings by modification with "active" and "non-active" silanes is presented."Active" silanes are defined as ones having functional groups that can react with the epoxy groups in the epoxy resin,usually amino-silanes."Non-active" silanes are defined as ones not reacting with the epoxy groups,but can react with the hydroxyl groups in the epoxy backbone by the condensation reactions under the catalysis of organic tin compounds.The FTIR results showed that both... |
