Patent

CA 2227577

The invention is a cleaning solution for degreasing metal articles which contain water soluble, N-alkyl substituted amides in which the alkyl substituent has from 6 to 22 carbon atoms and at least one of (i) amine oxide surfactants, (ii) non-ionic water soluble surfactants with molecules containing a polyoxyalkylene block, and (iii) alkali stable anionic, or both anionic and amphoteric, surfactants. Preferred compositions of the invention can replace a vapor degreasing process for cleaning oil, grease, and waxy-type contaminants from metal articles to the level of cleanliness required in the aerospace industry.

L'invention concerne une solution de nettoyage qui est destinée à dégraisser des articles métalliques et comprend des amides solubles dans l'eau, à substitution N-alkyle, et dans lesquels le substituant alkyle possède 6 à 22 atomes de carbone, ainsi qu'au moins un tensioactif choisi parmi les groupes suivants: (a) tensioactifs d'oxyde d'amine, (b) tensioactifs non ioniques, solubles dans l'eau et possédant des molécules contenant un bloc polyoxyalkylène, et (c) tensioactifs anioniques stables alcalins, ou à la fois anioniques et amphotères. Le procédé de dégraissage à l'aide de compositions préférées de l'invention peut remplacer celui à la vapeur, afin de nettoyer des articles métalliques de contaminants à base d'huile, de graisse et de type paraffineux, et atteindre le niveau de propreté requis dans l'industrie aérospatiale.
