- compositions intended to limit the metal / metal friction during point-to-point metal shaping operations for example, lubricating compositions for drawing under extreme pressure or metal cutting compositions; and or
- compositions intended to limit the wear of metal parts intended to be put in contact with each other repeatedly engine oil compositions or gearboxes, typically.
- the above lubricating additives are generally added in paraffinic type oil-based lubricating formulations or the like for metal forming applications.
- the lubricating formulation which incorporates lubricant additives is typically based on naphthenic type oil or else on polyalphaolefins (PAO) and poly (alkylene glycols). or esters.
- lubricant additives for metal of the aforementioned type mention may be made in particular of compounds bearing a phosphonate end group, and in particular the additive LUBRHOPHOS® LB-400 (polyoxyethylene octadecenyl ether phosphate) available from the Solvay company.
- LUBRHOPHOS® LB-400 polyoxyethylene octadecenyl ether phosphate
- An object of the present invention is to provide lubricating additives ensuring a greater and / or more lasting lubrication effect than that obtained with phosphonate compounds of the LUBRHOPHOS LB-400 type.
- the present invention proposes the use of specific copolymers based on several units carrying phosphorus group and hydrophobic units.
- these copolymers can be used as a lubricant for metal and / or to provide a protective effect, in particular an anti-wear effect or an anti-corrosion protection treatment on the surface of metals (temporary passivation effect or more durable anti-corrosion effect, especially on aluminum surfaces).
- the subject of the invention is the use, as lubricant for metal and / or protective agent for metal, typically as an additive in a lubricating composition comprising at least one oil of naphthenic or paraffinic type, a copolymer as obtained by radical copolymerization of a mixture comprising:
- monomers m1 also known as “phosphorated monomers”, ethylenically unsaturated and carrying phosphorus groups
- - M2 monomers also called “hydrophobic monomers", carrying a saturated or unsaturated hydrocarbon chain, preferably an alkyl or alkenyl group, typically having from 8 to 30 carbon atoms, these monomers m2 being generally non-phosphorus.
- copolymers of the invention are typically usable to provide a lubricating effect, in particular to limit the metal / metal friction during metal forming operations (for example during the drawing of metals under extreme pressure or during metal cutting) and / or to limit the wear of metal parts intended to be placed in contact with each other repeatedly (engines or gearboxes typically).
- the copolymers of the invention more generally allow a protective effect of metal surfaces, in particular a passivation effect, and their deposition on the surface of metal surfaces (steel, aluminum, copper or brass, for example) makes it possible to reduce or even reduce completely inhibit the phenomena of corrosion.
- the subject of the invention is the lubricating compositions comprising at least one copolymer of the aforementioned type, typically in admixture with a paraffinic oil or a naphthenic oil).
- the subject of the invention is protective compositions for metal, especially passivating or anti-corrosion compositions for metal, comprising at least one copolymer of the aforementioned type.
- the work carried out by the inventors in the context of the present invention has now made it possible to demonstrate that the copolymers obtained by radical copolymerization of the mixture of the above-mentioned monomers m1 and m2 prove to be particularly effective in ensuring a lubricating effect on a mixture. metal surface.
- a copolymer according to the invention which comprise a large number of phosphorus groups, especially when the monomers m1 are monomers VPA (vinylphosphonic acid).
- a copolymer according to the invention it is preferable for a copolymer according to the invention to comprise at least 2 phosphorus groups per chain, for example at least 3 and preferably at least 5, more preferably at least 8 and even more preferably at least 10.
- the number of phosphorus groups per copolymer can typically be from 5 to 50, for example from 10 to 40. It generally does not have to exceed 20 to obtain interesting results, but it can be superior. According to a particular embodiment, it is between 5 and 30. For example, it can be typically between 10 and 15, for example of the order of 12. Alternatively it can be between 15 and 35, for example from order of 25 to 30.
- the number of phosphorus groups to which reference is made here typically corresponds to an average number of phosphorus groups on all the chains of the copolymer under consideration. This number of phosphorus groups per chain can typically be established from:
- the size of the copolymers according to the invention is as small as possible.
- the number-average molecular weight of a copolymer used according to the invention is less than 100 kg / mol, more preferentially less than 60 kg / mol, for example between 5 and 50, and more preferably between 10 and 40. kg / mol, and more advantageously between 10 and 30 kg / mol, for example of the order of 20 kg / mol.
- the number-average molecular weight of a copolymer used according to the invention is not too low, in particular so as to be able to more easily control the number of phosphorus groups per chain.
- the number-average molecular mass it is most often preferred for the number-average molecular mass to remain greater than or equal to 5 kg / mol, more preferentially to 10 kg / mol.
- the number-average molecular mass referred to in the present description corresponds to the theoretical number average molecular weight of the copolymer, which is calculated by the overall ratio of the total mass of monomers theoretically incorporated into the polymer (which is equal to the sum of the products of the mass of each monomer employed in the manufacture of the copolymer multiplied by the conversion of said monomer), divided by the total number of copolymer chains.
- the copolymers of the invention can be typically used in the same concentration ranges as LUBRHOPHOS LB-400, or even at slightly lower levels, with at least similar performance.
- the copolymers according to The invention is generally much more efficient than the LUBRHOPHOS LB-400, and this same employees in lesser amounts.
- the copolymers of the invention constitute an excellent alternative to LUBRHOPHOS LB-400.
- the constituent phosphorus monomers of the copolymers according to the invention are unsaturated monomers bearing at least one phosphorus group.
- the monomers m1 are typically vinylphosphonic acid (VPA) monomers.
- OA phosphate ester group -O-P
- OA phosphonate ester -P
- the hydrophobic monomers m 2 can vary to a large extent, provided that they are copolymerizable monomers radical polymerization with phosphorus monomers m1.
- the monomers m2 can for example be chosen from:
- esters of acrylic acid of formula:
- R h is a saturated or unsaturated hydrocarbon chain, preferably an alkyl or alkenyl group, typically having from 8 to 30 carbon atoms
- esters of methacrylic acid of formula:
- R h is a saturated or unsaturated hydrocarbon chain, preferably an alkyl or alkenyl group, typically having from 8 to 30 carbon atoms
- R h is a saturated or unsaturated hydrocarbon chain, preferably an alkyl or alkenyl group, typically having from 8 to 30 carbon atoms
- CH 2 C (CH 3 ) -C-O-R h
- R h is a hydrocarbon chain, saturated or unsaturated, preferably an alkyl or alkenyl group, typically having from 8 to 30 carbon atoms alkenes such as butylenes and isobutylene.
- the monomers m.sub.2 may for example be 2-ethylhexyl esters of acrylic acid (2-ethylhexyl acrylate, referred to as "2EHA").
- copolymers useful according to the invention may be prepared according to any radical polymerization process using the monomers m1 and m 2 in a mixture.
- the copolymers used according to the invention are typically random copolymers based on the monomers m1 and m.sub.2, it being understood that they may have gradients of concentrations of said monomers, especially in view of the difference in reactivity between the monomers.
- copolymers according to the invention are not block copolymers, although this embodiment is not excluded from the scope of the invention.
- the copolymers according to the invention are prepared by controlled radical copolymerization of a mixture comprising the monomers m1 and m2.
- Controlled radical polymerization is a technique that is well known per se, which makes it possible, using a polymerization control agent, to obtain polymers of controlled masses, and in particular block polymers which can be controlled at the same time. the architecture and size of each block.
- the size of the polymer in formation is controlled by the molar ratio monomer / control agent corresponding to the initial amount of monomers relative to the amount of control agent: schematically, all the chains grow from each of the present control agents and the monomers are evenly distributed over all growing chains.
- the monomer / control agent molar ratio thus dictates the degree of polymerization of the block synthesized in each of the steps, and thus makes it possible to define the theoretical average molecular weight expected for each of the blocks.
- the useful copolymer according to the invention is prepared by bringing into contact:
