Corrosion protection formulation for protection against zinc and cadmium corrosion

摘要

Corrosion protection formulation comprising (A) from 0.01 to 5% by weight of alkylamine ethoxylates as surfactant component, (B) from 0.01 to 10% by weight of corrosion inhibitors, (C) from 0 to 0.3% by weight of thickeners, (D) from 5 to <75% by weight of freezing point-lowering alcohols selected from among alkanols, glycols, polyalkylene glycols and glycerol, (E) from 5 to 90% by weight of vegetable and/or fatty oils, (F) from 0 to 5% by weight of water and (G) from 0 to 5% by weight of conventional emulsifiers. The formulation is particularly suitable for protecting zinc or zinc-plated components or surfaces or cadmium or cadmium-plated metallic surfaces against corrosion caused by runway deicing compositions used at airports.

1. A formulation, comprising:
0.01 to 5% by weight of an alkylamine ethoxylate as a surfactant, 0.01 to 10% by weight of a corrosion inhibitor, 0 to 0.3% by weight of a thickener, greater than or equal to 5% but less than 75% by weight of at least one freezing point-lowering alcohol selected from the group consisting of an alkanol, a glycol, a polyalkylene glycol, and glycerol from 5 to 90% by weight of a vegetable oil, a fatty oil, or both, from 0 to 5% by weight of water, and from 0 to 5% by weight of an emulsifier, wherein said corrosion inhibitor comprises an alkoxylated castor oil and optionally at least one further corrosion inhibitor.
