本研究分别对铝板表面进行磷酸阳极化和硫酸阳极化处理,采用电子扫描电镜对处理后的铝板表面形貌进行了观察,结果表明磷酸阳极化后的铝板表面更加粗糙;测试了两种处理后铝板的粘接强度,硫酸阳极化后的铝板拉伸剪切强度为23.8MPa,磷酸阳极化铝板拉伸剪切强度为31.2MPa,说明磷酸阳极化更有利于铝板的粘接。采用与胶黏剂体系相同的底胶对磷酸阳极化后的铝板进行保护,放置五天后的铝板拉伸剪切强度为31.1 MPa,铝板粘接强度无降低,为实际工程使用铝制件的粘接提供了一种保护方法。 In this study, the surface of aluminum plate was anodized by phosphoric acid and anodized by sulfuric acid. The surface morphology of the treated aluminum plate was observed by SEM. The results showed that the surface of the anodized aluminum plate was rougher. The bonding strength of aluminum plate, aluminum plate anodized sulfuric acid tensile shear strength of 23.8MPa, anodized aluminum phosphate tensile shear strength of 31.2MPa, indicating that phosphoric acid anodizing is more conducive to the bonding of aluminum. Using the same primer as the adhesive system, the phosphoric acid anodized aluminum plate was protected. After five days of storage, the tensile shear strength of the aluminum plate was 31.1 MPa, and the aluminum plate had no decrease in adhesive strength. For the actual project, Connection provides a method of protection.
