Abstract: In order to solve the problem that the hydrophobicity of the silicone rubber shed reduces due to contamination and aging, a laser cleaning technology is used to remove the surface contamination and aging surface of the silicone rubber shed. Based on the principle of rapid gasification of the silicone rubber when irradiated by a laser spot, the contamination and aging surface of the silicone rubber shed are removed. The power of the laser spot used for cleaning is 66W, spot pulse 200kHz, cleaning width 3cm, walking speed 3mm/s and cleaning depth 0.03mm/time. Fourier transform infrared spectroscopy (Fourier transformed infrared spectroscopy, FTIR) and 200 times surface cracking observation are carried out on the silicone rubber surfaces with different cleaning depths. When the cleaning depth is greater than or equal to 0.1 mm, the hydroxyl bond (-OH) will be significantly reduced. The disordered functional groups are removed and the cracking is almost disappeared near the SiO₂ bonds and silicone methyl spectrum. Therefore, the recommended cleaning depth is 0.1-0.2mm. After laser cleaning, the silicone rubber surface has good hydrophobicity migration, and the recovery and migration of the hydrophobicity loss of the silicone rubber surface are significantly improved compared with those of non-cleaned surface.
