Definitions
- the invention relates to an aqueous lubricant intended to be used for metalworking, in particular for the deformation of metal parts, or the forming, cutting, stamping or rolling of metal parts, in particular aluminum or steel. .
- the solvent generally serves as a vector allowing the fatty substance useful for lubrication to be deposited on the surface of the metal, the solvent evaporating during the operation.
- these products containing non-aqueous solvents can be toxic and therefore present a potential health risk.
- the presence of these non-aqueous solvents can also lead to the marketing of labeled products and the need, for people using these products, to wear protective equipment, particularly personal protective equipment, when handling the product.
- An objective of the present invention is to provide a lubricating composition, in particular a lubricating composition for working metals, limiting the use of non-aqueous solvent, in particular toxic or potentially toxic solvent and thus presenting an improved ecodesign profile.
- aqueous-based formulations currently on the market do not always meet the expectations of players for the deformation of metal parts, particularly aluminum, from a part quality point of view since they are likely to generate staining problems during a heat treatment, a heat treatment generally being carried out after the deformation of a metal part, in particular an aluminum part. Tests carried out with products intended primarily for steel may present limitations on aluminum, a softer material requiring the addition of specific additives.
- the present invention proposes a lubricating composition having improved lubricating properties for the deformation of metal parts, in particular aluminum and steel, composition generating little or no volatile organic compounds (VOC) when it is heated in particular up to 80°C.
