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.
Use of “Active” and “Inactive” silane chemically modified epoxy coatings to increase their corrosion resistance. “Active” Silane refers to compounds that contain ring-opening reactions with the epoxy end groups of epoxy resins Functional silane, usually aminosilane; “Inactive” “Silane” means a silane that does not react with the epoxy end groups but which condenses with hydroxyl groups on the epoxy backbone in the presence of an organotin catalyst. Shows that both types of silanes can be successfully grafted onto the epoxy resin.The electrochemical impedance spectroscopy (EIS) and accelerated corrosion test (Machu test) tests show that the silane modified epoxy coating can improve its resistance Erosion performance.
