摘要

Abstract: Painted metal exteriors of buildings begin to degrade in about 10 years due to solar heat, UV rays, the sea salt adhesion, the acid rain etc. When degradation and exfoliation of the paint film occurs, rust appears in the metal and replacement or repainting becomes necessary. The adhesion of paints on metal is usually achieved by chemical adhesion or by increasing the surface area by blast processing. In this study, the possibility of improving paint adhesion by forming minute holes on the metal surface by laser irradiation was studied through modeling of the adhesion of the paint film and adaptability to deformation. The viscosity and painting method depend on the size and location of the oles. The presence of the holes makes it possible to form complicated shapes by pressing because the holes absorb some of the strain caused by pressing. !1
