| 摘要 |
In broad terms, the invention provides for novel corrosion inhibiting materials obtained by a chemical reaction between a Mannich base and other suitable reactants. The Mannich bases of this invention are derived from hydroxyaromatic compounds, secondary amines or cyclic secondary amines and aldehydes. The other reactants include: organo-metallic compounds, metal oxides, carboxylic acids, inorganic acids, inorganic acid derivatives, alkyl halides, organosilanes and quarternary ammonium derivatives and metal derivatives The corrosion inhibitors of the invention are liberated upon hydrolysis in the presence of humidity and are particularly suitable for incorporation in polymers, cements, paints, papers, cardboard, textiles.
