Abstract[English]
The present disclosure is directed to an aqueous lubricating composition having utility in the cold working of metallic substrate, said aqueous lubricating composition comprising, based on the weight of the composition: from 1 to 20 wt.% of a) at least one water-soluble inorganic salt, said inorganic salt or salts being in a dissolved state; b) at least one particulate solid lubricant; from 0.1 to 5 wt.% of c) at least one rheological control agent; from 0.1 to 5 wt.% of d) at least one base; and, from 0.1 to 5 wt.% of e) at least one surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and zwitterionic surfactants, wherein said composition is free from boron and boron compounds and is further characterized in that the ratio by weight of b) said at least one solid lubricant to a) said at least one water-soluble inorganic salt [(b):(a)] is from 0.1:1 to 1:1.[French]
La présente divulgation concerne une composition lubrifiante aqueuse ayant une utilité dans le travail à froid d'un substrat métallique, ladite composition lubrifiante aqueuse comprenant, sur la base du poids de la composition : de 1 à 20 % en poids de a) au moins un sel inorganique hydrosoluble, le(s)dit(s) sel(s) inorganique(s) étant dans un état dissous ; b) au moins un lubrifiant solide particulaire ; de 0,1 à 5 % en poids de c) au moins un agent de régulation rhéologique ; de 0,1 à 5 % en poids de d) au moins une base ; et, de 0,1 à 5 % en poids de e) au moins un tensioactif choisi dans le groupe constitué par des tensioactifs anioniques, des tensioactifs non ioniques, des tensioactifs cationiques, des tensioactifs amphotères et des tensioactifs zwittérioniques, ladite composition étant exempte de bore et de composés de bore et étant en outre caractérisée en ce que le rapport en poids de b) ledit au moins un lubrifiant solide à a) ledit au moins un sel inorganique hydrosoluble [(b) : (a)] est de 0,1 : 1 à 1 : 1.
