Abstract
Maltooligosaccharide syrup is hydrogenated under nickel catalyst and high pressure so as to reduce the end-groups of the maltooligosaccharide syrup. The reduced syrup and cyclodextrin are mixed, and the volatile corrosion inhibitor is included by means of the cyclodextrin to form cyclodextrin clathrate compound of volatile corrosion inhibitor. The cyclodextrin clathrate compound of volatile corrosion inhibitor is mixed with a thermoplastic synthetic resin, such as polypropylene, polyethylene, ethylene-vinyl acetate copolymer, polyvinyl chloride. Then, the thermoplastic resin mixed with the volatile corrosion inhibitor is formed in a desired shape, by way of blown-film extrusion, injection molding or expansion molding. The thus obtained rust preventive comprises a thermoplastic synthetic resin including a cyclodextrin clathrate compound of volatile corrosion inhibitor.
