Definitions

  • the invention relates to the use of an oily composition for the temporary treatment of metal surfaces for both lubrication and resistance to corrosion. It also relates to a corresponding composition.
  • the metal surfaces are temporarily protected against corrosion by applying a layer of 1 to 1.5 g / m 2 of a composition based on mineral oil and additives.
  • a composition based on mineral oil having low lubricating properties it is necessary to. proceed with the application of a second lubricating oily layer on the metal surface before shaping it by stamping under optimal conditions.
  • the application of two successive layers of oil on the metal surface constitutes a loss of productivity in the step of implementing the surface.
  • the object of the present invention is to provide an oily composition which makes it possible to meet all of the abovementioned objectives, consisting of whole oils, biodegradable and fluids at room temperature intended for temporarily treating metal surfaces both for lubrication and against corrosion.
  • the present invention firstly relates to the use of an oily composition for temporarily protecting and lubricating metal surfaces, characterized in that said composition contains:
  • composition in accordance with the invention that is to say combining the components A, B, C and, where appropriate, D proves to be particularly advantageous in use as pretreatment of metal surfaces before rolling, or before stamping for the following reasons:
  • composition is biodegradable
  • composition can be used as it is without it being necessary to heat or dissolve it,
  • this composition is effective both in low pressure lubrication, in high pressure lubrication and in corrosion protection,
  • the treated metal surfaces are easily degreasable, - the composition is stable and its degreasability does not decrease over time,
  • the composition is compatible with conventional rolling or stamping oils, - the composition is easily applicable in a thin layer by electrostatic oily.
  • Compounds A and B are derived from fatty acid triglycerides comprising a C ⁇ 18 aliphatic hydrocarbon group and are either natural vegetable oils or synthetic oils obtained by reaction of one mole of glycerol with three moles of fatty acid or a mixture of fatty acids.
  • the fatty acid triglycerides retained come from natural vegetable oils so as to obtain a biodegradable composition.
  • - unsaturated aliphatic acids such as oleic acids (C 18 - 1 unsaturation), linoleic acids (C 18 - 2 unsaturations), linolenic acids (C 18 - 3 unsaturations), - hydroxy acids such as ricinoleic acid (C 18 - 1 unsaturation) .
  • compound B is preferably a fatty acid triglyceride with an oleic acid content of at least 60%.
  • Oleic acid can be naturally present in vegetable oils in significant proportions. As such, there may be mentioned olive oil which naturally contains 65 to 85% oleic acid.
  • vegetable oils such as soybean oil, rapeseed oil, safflower oil, palm oil or sunflower oil, have much lower levels of oleic acid; these contents are of the order of 25 to 60%.
  • the plants from which these oils are extracted undergo genetic modifications by hybridization according to conventional methods.
  • the oleic acid contents in these genetically modified oils are significantly increased; they are of the order of 60 to 90%, preferably 65 to 85%, of the total fatty acid content.
  • These genetically modified vegetable oils are preferably chosen as compound B.
  • compound C it is preferably a monoester or a polyester of a fatty acid derived from the condensation of a fatty acid with an alcohol.
  • the fatty acids from which compound C is derived are chosen from the fatty acids already described for compound A.
  • the alcohols are chosen from: - aliphatic alcohols comprising a unique hydroxy function in Q, ⁇ 2 such as methanol (C, ethanol (C 2 ), isopropanol (C 3 ) and ethylhexanol (C 8 ),
  • C 1 to C 12 aliphatic alcohols comprising several hydroxy functions, and more particularly C 5 polyols such as pentaerythritol.
  • compound A is particularly advantageous for its low pressure lubrication properties and easy degreasability, as for compound B, it is selected for its good high pressure lubrication performance, finally compound C, in addition to its satisfactory performance in terms of degreasing and high and low pressure lubrication, contributes to improving the corrosion resistance of composition A, B, C.
  • the compounds A, B and C are chosen so that the iodine index their mixture is less than 100.
  • the iodine index is the mass of iodine in grams fixed by 100 g of a fat body. The higher the iodine index, the more the fatty substance or mixture of fatty substances has a high number of unsaturations.
  • this iodine index is adjusted so as to obtain a compromise in terms of degree of unsaturation.
  • the problems of oxidation of unsaturated fatty acids which results from the reaction of oxygen on the double bonds of the aliphatic chain to form allylic hydroperoxides decomposing into secondary products such as: aldehydes, ketones, alcohol, it is desirable that the mixture of compounds A, B and C has the lowest possible number of unsaturations.
  • the iodine index of the mixture A, B, C is preferably between 20 and 100.
  • composition A, B, C a fourth component D consisting of an amide, the lubrication and corrosion resistance properties are further improved.
  • a representative of compound D capable of being used according to the invention mention may be made of amides derived from the condensation of a fatty acid and an amino.
  • the fatty acids from which compound D is derived are chosen from the fatty acids already described for compound A.
  • the amines are chosen from mono-, di- or tri-C 2 - c 6 alkanolamines.
  • the present invention also relates to an oily composition for the temporary treatment of metallic surfaces, characterized in that said composition contains:
  • each of the compounds A, B, C and D is chosen in order to satisfy all of the criteria mentioned above.
  • the fatty acid of compound A is a saturated aliphatic acid (iodine index from 1 to 20) chosen from lauric, myristic, palmitic and stearic acids.
  • coconut oil Like all fatty substances, coconut oil consists of a mixture of triesters between its fatty acids and glycerol.
  • the fatty acid composition of coconut oil is as follows: 46% acid lauric (C 12: 0 ), 18% myristic acid (C 14: 0 ), 10% palmitic acid (C 16: 0 ) and 7% oleic acid (C 18; 1 ).
  • compound B is a modified sunflower oil genetically enriched in oleic acid. It will be called hereafter, oleic sunflower oil. Its fatty acid composition is as follows: 80% oleic acid (C 18: 1 ), 9% linoleic acid (C 18: 2 ), 5% stearic acid (C 18: 0 ) and 3% palmitic acid (C 16; 0 ).
  • the compound C chosen is a fatty acid monoester.
