Definitions
- the present invention relates to the field of lubricants and more particularly that of aqueous lubricants containing water-soluble additives extreme pressure, useful for working or shaping metals.
- a lubricant in order to reduce the forces between the workpiece and the tool, remove chips and debris, cool and control the surface condition of the workpiece. or of the worked sheet.
- oil-based lubricants have been used. These are whole oils or emulsions to which lubricants, antiwear (AU) and / or extreme pressure (EP) additives have been optionally added.
- EP additives are generally compounds containing sulfur. Under the high temperatures encountered at the contact between metal parts during metalworking operations, sulfur compounds decompose. A layer of iron sulphide is formed on the surface of the parts which prevents welding and adhesion phenomena.
- Whole oils have excellent lubricating properties but when the rates are high, the evacuation of heat requires the use of emulsions. However, the use of emulsions also tends to be reduced because over time they are degraded and generate bad odors.
- aqueous fluids develop more and more. These are either synthetic fluids which are aqueous solutions based on water-soluble additives, or semi-synthetic fluids which are oil-in-water microemulsions containing a large quantity of emulsifiers.
- synthetic fluids which are aqueous solutions based on water-soluble additives
- semi-synthetic fluids which are oil-in-water microemulsions containing a large quantity of emulsifiers.
- the EP additives have been developed for oils, so that very few of these additives are dissolved in water and are suitable for aqueous fluids. If there are a number of oil-soluble EP additives, the number of water-soluble EP additives is much more limited. In Lub. Eng.
- AMS is not very corrosive; in aqueous solution, it does not release H 2 S. AMS is easily biodegradable (100% decomposition in 28 days), which is favorable for the environment. AMS brings particularly interesting extreme pressure properties to lubricant formulations.
- the present invention therefore relates to a process for working or shaping metals in the presence of an aqueous lubricant containing a water-soluble extreme pressure additive, characterized in that this additive is methanesulfonic acid (AMS) or a water-soluble salt AMS.
- AMS methanesulfonic acid
- AMS water-soluble salt AMS.
- the water-soluble salts of AMS according to the invention are obtained by neutralization of AMS with a salifying agent.
- the alkali metal or alkaline-earth metal salts are preferred, but the water-soluble salts obtained from compounds corresponding to the general formula: R 1 NR 2 R 3 may also be used.
- R 1 , R 2 and R 3 which are identical or different, each represents a hydrogen atom, an alkyl, alkenyl or alkylaryl radical having from 1 to 22 carbon atoms, or an oxyethylated radical of the form (CH 2 -CH2-0) n H, n being between 1 and 20.
- alkaline salts those obtained by neutralizing the AMS with sodium hydroxide or potassium hydroxide are preferred.
- R 1 NR 2 R 3 mention may be made of alkanolamines, in particular monoethanolamine, diethanolamine or triethanolamine, ethoxylated amines of which those preferred are those for which R 1 is a radical having from 12 to 22 carbon atoms, R 2 and R 3 are oxyethylated radicals comprising between 1 to 10 groups of ethylene oxide.
- the salifying agent is added in stoichiometric proportion with respect to the AMS, in excess with respect to the AMS, or in default with respect to the AMS, according to the desired pH for the final formulation. It is preferred that the molar ratio between the AMS and the salifying agent is between 1: 1 and 1: 2.
- the water-soluble salts of AMS according to the invention are perfectly stable in water at room temperature and make it possible to obtain concentrated or diluted aqueous lubricating formulations which are easily stored without release. ment of H 2 S and have particularly advantageous extreme pressure properties.
- AMS or the water-soluble salts of AMS can be presented in the form of a concentrate which can be diluted later during use, or in the form of a diluted solution. They can be used alone, but in general, they are used in admixture with other usual additives of synthetic or semi-synthetic fluids for working or shaping metals. Among these additives, mention may be made of bactericidal agents, emulsifiers, oiliness agents, anti-wear additives, defoamers, corrosion inhibitors.
- the concentrates contain between 10% and 50% by weight of AMS or of water-soluble salt of AMS, preferably between 15% and 35%.
- AMS or the water-soluble salts of AMS according to the invention can be incorporated into the aqueous lubricants usually used for working or shaping metals, more particularly synthetic fluids (true solutions) or semi-synthetic fluids (microemulsions), in weight concentration ranging from 0.01% to 20%, and preferably between 0.1% and 10%.
- the effectiveness of the extreme pressure additives according to the invention is evaluated by tests on a 4-ball machine by the 4-ball extreme pressure test according to standard ASTM D-2783: this test consists in evaluating the extreme pressure power of a fluid. by the value of the load from which 4 balls are welded together preventing the rotation of the upper ball on the 3 others held in the fluid to be tested, according to the following measurement protocol:
- the anti-corrosion power of the extreme pressure additives according to the invention is evaluated by bringing cast iron chips into contact with the aqueous lubricant to be tested according to the following protocol:
- Table 2 summarizes the composition and the extreme pressure performance of the different formulations tested; these are dilute aqueous formulations of AMS or 1: 1 water-soluble salts of AMS. They contain 5% by weight of water-soluble additive.
- the lubricant formulations based on AMS or on a water-soluble salt of AMS make it possible to obtain a solder load> 160 kg, much greater than that measured with pure water taken as a witness.
- the incorporation of an additive based on AMS or a water-soluble salt of AMS according to the invention makes it possible to provide extreme pressure properties to the aqueous formulations used for working or shaping metals. AMS and the Na and K salts of AMS provide the highest performance.
- Table 3 shows the extreme pressure performances as well as the corrosion resistance properties of 2 aqueous lubricants containing a water-soluble salt of AMS in accordance with the invention. These compositions are prepared by neutralizing the AMS with an excess of sodium hydroxide (NaOH) or of monoethanolamine (MEA). The water-soluble salt is at a concentration by weight of 5% in water; the compositions are clear, stable and without any particular odor. Table 3
- compositions 8 and 9 according to the invention make it possible to obtain high welding loads during the 4-ball EP test. They have good properties with respect to corrosion.
