Composite copper surface corrosion inhibitor for copper zipper and preparation method of composite copper surface corrosion inhibitor

Номер: CN103643236A
Автор: JIANG YINGZHI, LIN WEIQIN
Принадлежит:

The invention relates to a composite copper surface corrosion inhibitor for a copper zipper and a preparation method of the composite copper surface corrosion inhibitor. The composite copper surface corrosion inhibitor is prepared from benzotriazole (BTA), 8-quinolinol (HQ), an additive and water. Benzotriazole (BTA) and 8-quinolinol (HQ) have a synergistic corrosion inhibition effect for copper corrosion in an electrolyte solution, and the mechanism is as follows: 8-quinolinol (HQ) can be coordinated with Cu<2+> generated by corrosion to form a [Cu(II)-OC9H6C] complexing film which is used as the additive at a defect of a [Cu(I)-BTA] protective film to form a more compact protective film on the surface of metal copper, so that the protective capability for metal is enhanced. A copper surface treated by the composite copper surface corrosion inhibitor is stronger in corrosion inhibition capability than the copper surface treated by the traditional benzotriazole (BTA) treating fluid; proved ...
