    • 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.
    • 在镍催化剂和高压下氢化麦芽低聚糖糖浆,以减少麦芽低聚糖糖浆的端基。 混合稀释的糖浆和环糊精,通过环糊精包含挥发性腐蚀抑制剂,形成挥发性缓蚀剂的环糊精包合物。 将挥发性缓蚀剂的环糊精包合物与聚丙烯,聚乙烯,乙烯 - 乙酸乙烯酯共聚物,聚氯乙烯等热塑性合成树脂混合。 然后,与挥发性缓蚀剂混合的热塑性树脂通过吹塑薄膜挤出,注射成型或膨胀成型形成所需的形状。 由此得到的防锈剂包括含有挥发性缓蚀剂的环糊精包合物的热塑性合成树脂。
