Multifunctional Composition and Method For Treating a Metal Surface With the Multifunctional Composition

摘要

The present invention is directed to an anticorrosion composition and a method for preventing or inhibiting the corrosion of a metal substrate utilizing an anticorrosion compound. The method utilizes an anticorrosion composition comprising at least one amine oxide and at least one N-containing compound. The invention relates to a method for inhibiting the corrosion of metal surfaces by applying the composition to a metal substrate. The composition of the present invention provides corrosion inhibition, cleaning capabilities, and conversion capabilities.

1. An anticorrosion composition comprising
at least one amine oxide having the formula wherein
R1 is a linear, branched, or cyclic C6-40 saturated or unsaturated group,R2 and R3 are each independently of one another H or a linear, branched, or cyclic C1-40 saturated or unsaturated group, and at least one N-containing compound having the formula wherein
R4 is a linear, branched, or cyclic C1-40 saturated or unsaturated group,R5 and R6 are each independently of one another H or a linear, branched, or cyclic C1-40 saturated or unsaturated group or R5 and R6 are both taken together in combination with the N to which they are attached to form a cyclic or heterocyclic group, optionally substituted.
