HIGHLY CORROSION-RESISTANT SURFACE-TREATED STEEL PLATE |
摘要 |
The present invention relates to a highly corrosion-resistant surface-treated steel plate. The steel plate of the present invention comprises a zinc deposition or zinc alloy deposition film as the undercoat deposition layer, a chromate film formed on the undercoat deposition layer and a film of a resin composition formed on the chromate film. This resin composition comprises a base resin formed by adding at least one basic nitrogen atom and at least two primary hydroxyl groups to terminals of an epoxy resin. The resin composition may comprise a polyisocyanate compound as the curing agent. Furthermore, the resin composition may comprise silica or a hardly soluble chromium compound as the additive for improving the corrosion resistance. Moreover, the resin composition may comprise a silane compound as the crosslinking agent for the base resin and silica. |
