Abstract

L'invention décrit l'obtention de compositions stabilisées de fluides pour le travail des métaux. Les compositions contiennent une dispersion d'huile et d'eau, un agent d'émulsionnement (anionique et/ou non ionique) conférant de l'électronégativité à la phase huileuse de la dispersion et, comme stabilisant, un ion de métal multivalent lié par coordination à l'agent électronégatif d'émulsionnement et qui a été introduit sous forme d'un complexe d'un ion de métal et d'un ligand organique polyfonctionnel (par exemple du monocuivre (II)-citrate disodique). Ce complexe peut, entre pH 7 et 9, libérer des cations de métal pour stabiliser l'émulsion et en empêcher la dégradation On peut ainsi prolonger très notablement la durée de service des fluides d'arrosage pour le travail mécanique des métaux.The invention describes the production of stabilized compositions of fluids for metalworking. The compositions contain a dispersion of oil and water, an emulsifying agent (anionic and / or nonionic) conferring electronegativity to the oily phase of the dispersion and, as stabilizer, a multivalent metal ion bound by coordination with the electronegative emulsifying agent and which has been introduced in the form of a complex of a metal ion and a polyfunctional organic ligand (for example mono-copper (II) -disodium citrate). This complex can, between pH 7 and 9, release metal cations to stabilize the emulsion and prevent its degradation. The service life of coolant fluids for mechanical metalworking can thus be extended very significantly.
