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.

Description

DESCRIPTION DESCRIPTION
TITRE : LUBRIFIANT AQUEUX POUR LE TRAVAIL DES METAUXTITLE: AQUEOUS LUBRICANT FOR METAL WORKING
DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION
L’invention concerne un lubrifiant aqueux destiné à être utilisé pour le travail des métaux, en particulier pour la déformation de pièces métalliques, ou encore le formage, la découpe, l’estampage ou le laminage de pièces métalliques, notamment en aluminium ou en acier. 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. .
ETAT DE LA TECHNIQUE STATE OF THE ART
Pour le travail des métaux, et notamment pour les opérations de déformation, en particulier sur l'aluminium, il existe des produits à base de formules comprenant un solvant et un corps gras. Le solvant sert généralement de vecteur permettant de déposer le corps gras utile pour la lubrification à la surface du métal, le solvant s'évaporant au cours de l'opération. For metalworking, and in particular for deformation operations, particularly on aluminum, there are products based on formulas comprising a solvent and a fatty substance. 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.
Cependant, ces produits comprenant des solvants non aqueux peuvent s'avérer toxiques et donc présenter un risque potentiel pour la santé. La présence de ces solvants non aqueux peut également amener à la commercialisation de produits étiquetés et à la nécessité, pour les personnes utilisant ces produits, à porter des équipements de protection, notamment équipements de protection individuels, lors de la manipulation du produit. However, 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.
De plus, ces produits à base de solvants non aqueux peuvent être difficiles à nettoyer et donc nécessiter l'utilisation de produits de nettoyage spécifiques et complexes à manipuler. Il existe donc un intérêt à fournir une composition lubrifiante, notamment pour le travail des métaux, permettant de répondre aux inconvénients de l'art antérieur et notamment limitant l'utilisation de solvant, notamment de solvant toxique ou potentiellement toxique. In addition, these non-aqueous solvent-based products can be difficult to clean and therefore require the use of specific cleaning products that are complex to handle. There is therefore an interest in providing a lubricating composition, in particular for metalworking, making it possible to address the disadvantages of the prior art and in particular limiting the use of solvent, in particular toxic or potentially toxic solvent.
Un objectif de la présente invention est de fournir une composition lubrifiante, notamment une composition lubrifiante pour le travail des métaux, limitant l'utilisation de solvant non aqueux, notamment de solvant toxique ou potentiellement toxique et présentant ainsi un profil d’écoconception amélioré. 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.
Les formulations base aqueuse ont été proposées pour limiter l’utilisation de solvant organique. Water-based formulations have been proposed to limit the use of organic solvent.
Les formulations base aqueuse actuellement sur le marché ne répondent pas toujours aux attentes des acteurs pour la déformation de pièces métalliques, notamment en aluminium, d’un point de vue qualité des pièces puisqu’elles sont susceptibles de générer des problèmes de tachage lors d’un traitement thermique, un traitement thermique étant généralement mis en œuvre après la déformation d’une pièce métallique, en particulier d’une pièce en aluminium. Les essais réalisés avec les produits destinés principalement à l’acier peuvent présenter des limites sur l’aluminium, matériau plus mou nécessitant l’apport d’additifs spécifiques. The 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.
Le document WO 2017/114827 décrit une formulation aqueuse comprenant un alcool gras alcoxylé et un agent anti-corrosion. Document WO 2017/114827 describes an aqueous formulation comprising an alkoxylated fatty alcohol and an anti-corrosion agent.
La présente invention propose une composition lubrifiante présentant des propriétés de lubrification améliorées pour la déformation de pièces métalliques, notamment l’aluminium et l’acier, composition générant peu voire pas de composés organiques volatils (COV) lorsqu’elle est chauffée notamment jusqu’à 80°C. 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.

Le tableau 3 indique le détail des compositions lubrifiantes testées dans cet exemple. [Tableau 3]
Figure imgf000029_0001
Table 3 indicates the details of the lubricating compositions tested in this example. [Table 3]
Figure imgf000029_0001
Le tachage est évalué en pulvérisant la composition lubrifiante sur une plaque en aluminium et en introduisant ladite plaque dans un four chauffé à 350°C et en maintenant la plaque 10 minutes à 350°C. Le niveau de tachage est évalué en attribuant une note de 0 (pas taché) à 5 (très taché). The staining is evaluated by spraying the lubricating composition onto an aluminum plate and introducing said plate into an oven heated to 350°C and maintaining the plate for 10 minutes at 350°C. The level of staining is assessed by assigning a score from 0 (not stained) to 5 (very stained).

[Table 4]
Figure imgf000029_0002
Comme le montrent les résultats du tableau 4, les compositions de l’invention sont moins tachantes que la composition CC3. En outre, les compositions Cl 1 , CI2 et CI4 comprenant un monoacide sont moins tachantes que la composition CI3 exempte de monoacide. As shown by the results in Table 4, the compositions of the invention are less staining than the CC3 composition. In addition, the compositions Cl 1, CI2 and CI4 comprising a monoacid are less staining than the composition CI3 free of monoacid.
En outre, la composition CI4 a démontré une diminution des résidus et donc des problèmes de collage pouvant survenir avec les dispositifs de transport des pièces métalliques à l’issue du procédé de travail des métaux desdites pièces. In addition, the CI4 composition has demonstrated a reduction in residues and therefore sticking problems that can arise with the transport devices of the metal parts at the end of the metalworking process of said parts.
