Compositions of vapour-phase corrosion inhibitors, method for their production and use of same for temporary corrosion protection

摘要

Evaporatable or sublimatable corrosion inhibiting substance combination, comprises (i) at least one polysubstituted pyrimidine, (ii) at least one monoalkyl urea, and (iii) at least one aminoalkyl diol with 3-5C. Independent claims are also included for: (1) a volatile corrosion inhibitor-corrosion protection oil, comprising a mineral oil or synthetic oil and the corrosion-inhibiting substance combination (2-10 wt.%, based on the oil phase) in a solubilizer, where all the corrosion inhibitor components of the volatile corrosion inhibitor oil sublimates at a temperature of 70[deg] C and at a relative humidity of = 98% with an amount and speed that is sufficient for vapor space corrosion protection; and (2) producing evaporatable or sublimatable corrosion inhibiting substance combination, comprising the mixing the components (i), (ii), (iii) and optionally (iv), and subsequently dispersing or dissolving in water or a solubilizer miscible with mineral oils and synthetic oils in any ratio.
