To achieve these goals, the present invention proposes a kind of aqueous, environmental protective inorganic agent for galvanized steel plain sheet,
The mass fraction of each component of this aqueous, environmental protective inorganic agent is:
Organo silane coupling agent A:4～50 parts；
Cationic water polyurethane resin B:40～80 parts；
Phosphorous, vanadium, titanium and at least one of compound C of zirconium, it is with phosphorus, vanadium, titanium and zirconium unit
The mass fraction that element amounts to is: 0.1～2.0 part；
