Anti-rust treating agent for nickel-plated battery steel shell and using method thereof

The invention relates to an anti-rust treating agent for a nickel-plated battery steel shell and a using method thereof. The formula of the agent mainly comprises the following components in percentage by weight: 0.5 to 10 percent of phytic acid, 0.5 to 10 percent of oxidant, 0.1 to 5 percent of auxiliary oxidant, 0.1 to 2 percent of complexing agent, 0.1 to 2 percent of corrosion inhibitor, 0.05 to 0.3 percent of wetting agent, 0.05 to 2 percent of pH conditioning agent and the balance of water. 0.1 to 1 percent of polyvinyl alcohol can also be added so as to enhance the film forming uniformity and compactness of the treating agent. The treating agent has high dispersing capability, infiltration capacity and enclosing capability and blocks micro-pores on the surface of a barrel nickel-plated battery shell and cracks on the surface of a pre-nickel-plated battery shell so as to prevent oxygen and other media from corroding the battery shell and enhance the resistance of the shell to severe environments such as
