| 摘 要： | 采用多参数测定仪在线检测KH550硅烷水解液的电导率和pH值,对影响水解体系的溶剂类型、硅烷偶联剂与溶剂配比、水解溶液pH值及水解时间等工艺参数进行研究,利用红外光谱对硅烷水解前后的分子结构进行表征。结果表明,KH550适合在无水乙醇和去离子水的混合溶剂中水解,水解后的硅烷膜中检测到Si-OH的特征峰。确定较佳水解工艺条件:KH550、去离子水、无水乙醇的体积比为1∶3∶6,水解液的pH值为4,水解时间为5h。

| Abstract: | Conductivity and pH value of KH550 silane coupling agent were measured on-line by multi-parameter analyzer. The technological parameters influencing the hydrolysis system, such as the type of solvent, the ratio of silane coupling agent to solvent, the pH value of hydrolysis solution and hydrolysis time were studied. The molecular structure of silane before and after hydrolysis was characterized by infrared spectroscopy. The results showed that KH550 was suitable for hydrolysis in the mixed solvent of anhydrous ethanol and deionized water. The characteristic peaks of Si-OH were detected in the hydrolyzed silane membrane. The optimum hydrolysis process were determined as follows: the volume ratio of KH550, deionized water and anhydrous ethanol was 1:3:6, the pH value was 4, and the hydrolysis time was 5 hours. |
