| 摘 要： | 采用红外光谱表征了KH-550的结构.用不同浓度的KH-550乙醇溶液处理铝表面,并用环氧胶黏剂粘接铝与铝的界面,测定其剪切强度.采用扫描电镜研究了KH-550预处理前后的铝与环氧胶黏剂体系的界面结合特征,并利用反射红外(RA-IR)对氨基硅烷偶联剂的作用机理进行了分析.试验研究表明,KH-550溶液涂覆后可明显改善铝与胶黏剂粘接界面的结合强度,环氧胶黏剂粘接强度可提高2～3 MPa. |

| Abstract: | Fourier transform infrared spectroscopy was used to characterize the structure of the KH-550. The bonding strength between Al and the adhesive was studied by the pretreatment with different concentration coupling agents. The interface bonding of Al/ epoxy resin adhesive system was studied using SEM and RA-IR. It was found that coupling agent had very strong hydrolysis ability and was able to increase the bonding strength 2 to 3 MPa. |
| Keywords: | Epoxy resin adhesive Coupling agent KH-550 Bonding strength |
