In order to prevent whitening and dropping powder of hot-dip galvanized passivation steel sheet in high humidity environment such as alternating humidity environment and the high temperature and humidity environment, the corrosion resistance, micro-morphology and main components of the whitening sample were studied. It was analyzed that the whitening was caused by the precipitation of inorganic substances in the coating. The preventive measures were determined as follows: synergistic effect of water-borne fluorine resin with colloidal SiO2 can elevate sealing effect of surface coating, then forms the surface coating technology for hot-dip galvanized steel sheet. Through performance research and product application, the results show that the environment-friendly coating has no quality problems in alternating humidity environment or the high temperature and humidity environment, so it has good high humidity resistance. The coating also has good corrosion resistance, fingerprint resistance and water resistance, which can meet the requirements of household appliances users.
