PURPOSE:To produce a volatile corrosion inhibitor inhibiting corrosion over a long period, by mixing a volatile corrosion inhibitor with a water absorbing resin and putting the mixture in a vessel made of a porous film. CONSTITUTION:A volatile corrosion inhibitor is mixed with a water absorbing resin such as starch-polyacrylate resin and the mixture is put in a vessel made of a porous film such as a porous PP film to obtain a volatile corrosion inhibitor kit. At least one among dicyclohexylammonium nitrite, cyclohexylammonium carbamate, diisopropylammonium nitrite, benzotrizole and tolyltriazole is used as the volatile corrosion inhibitor. The mixture is composed of about 5-70pts. wt. water absorbing resin and about 95-30pts.wt. volatile corrosion inhibitor and the amt. of the mixture is regulated to <=about 1/2 of the volume of the vessel. The water absorbing resin absorbs water produced by dew condensation in the vessel and only gas generated from the volatile corrosion inhibitor is released to obtain a significant corrosion inhibiting effect.
