Definitions
- the present invention relates to the field of lubricating compositions, and more particularly to lubricating compositions used in metalworking processes, such as operations for machining metal parts.
- the present invention relates to aqueous-based lubricating compositions.
- Lubricating compositions also called “lubricants”, are commonly used in mechanical systems, to reduce friction between parts and thus protect them against wear. In addition to wear phenomena, friction can oppose the relative movement of the parts in contact and induce energy losses that are detrimental to the optimal functioning of the mechanical system.
- Lubricants are used for multiple applications, from the lubrication of combustion vehicle engines to the lubrication of equipment used for machining operations, what is commonly called the work of metals, in particular for metal deformation operations.
- Metalworking more generally corresponds to the implementation of mechanical or metallurgical processes, both diversified or more specialized, which can be defined as shaping, cutting or jointing processes. This can also concern any mechanical transformation of metal, such as machining (turning, milling, drilling, sawing, threading, among others), forming, cutting, stamping or rolling.
- Operations relating to metalworking particularly require the use of lubricating compositions, with the aim of reducing the friction forces between the metal parts in contact and preventing their premature wear, while advantageously guaranteeing cooling of the latter. .
- compositions or metalworking fluids are also commonly designated under the names “compositions or metalworking fluids”, “lubricants or machining fluids” or “lubricants or cutting fluids”.
- the lubricant formulations used for such machining operations are lubricants composed mainly of one or more base oils, with which are generally associated additives dedicated to stimulating the lubricating performance of base oils, such as friction modifier additives.
- these lubricant formulations are classified according to the type of oil they contain. Thereby :
- Non-renewable fluids are those comprising mineral oils, such as paraffinic, aromatic or naphthenic oils, in their base formulation;
- Mineral fluids of synthetic origin are those comprising mineral oils or chemically modified petrochemical derivatives, in their base formulation such as, for example, polyalphaolefins, polyalkylene glycols and hydrogenated mineral oils;
- Renewable fluids of synthetic origin are those comprising chemically modified vegetable or animal oils, in their basic formulation such as, for example, vegetable oil esters, sulphited, oxidized, esterified vegetable oils or sulphated animal oils .
- mixed Some formulations, called mixed, include a mixture of the oils listed above in their base formulation.
- the best known are called semi-synthetic oils and correspond to a mixture of synthetic and mineral oils.
- oils or greases in lubricating compositions for metalworking has several disadvantages.
- oil-based lubricants generally have low resistance to microbial attack, poor cooling properties or even a negative impact on the working environment, health or safety.
- Lubricants in emulsion form comprising an aqueous phase added to an oily phase
- these lubricants exhibit poor stability partly due to water hardness and/or salinity.
- water-based compositions have shown some interest. These formulations generally include water, supplemented with various additives in order to guarantee the tribological properties required for lubricants, in particular in terms of reducing friction and protecting parts against wear.
- document GB 1 272 100 proposes an aqueous lubricant for metalworking comprising (1) a linear polypropylene glycol or an ethylene oxide/propylene oxide copolymer with a molecular weight of between 2000 and 9000 Da, and (2 ) a polyvinyl pyrrolidone, a cellulose ether or a triethanolamine phosphate.
- gummy residues appear after the machining operations. Once the machining equipment has stopped, the lubricant, subjected to ambient dehydration, is likely to lead to the formation of salts which, combined with the polymers present in the lubricant, can form relatively viscous and insoluble residues. in the aqueous phase, referred to as “gummy residues”.
- the present invention aims precisely to meet this need. Disclosure of Invention

- composition according to the invention make it possible to define uses according to the invention which are also particular, advantageous or preferred.
- the extreme pressure measurement is carried out by rotating a stainless steel ball on three stainless steel balls, also kept immobile, the 4 balls being entirely covered with a film of lubricant. A load is applied to the balls and gradually increased (every minute according to the parameters above) until the balls weld together. The balls are changed before each increase in load.
- the extreme pressure power corresponds to the value of the load from which the 4 balls are welded, preventing the rotation of the upper ball on the 3 others.
- This method also makes it possible to evaluate the anti-wear properties of a lubricating composition. During the gradual increase in load, it is possible to determine, at each level, the diameter of wear on the 3 balls. The smaller the wear diameter, the more effective the lubricant is in preventing wear (or seizing) of parts.
- the wear diameter values provided in the following examples are those obtained for the load value preceding the welding of the balls.
- the test for evaluating the formation of gummy residues is taken from standard ISO/TS 12-927 part B.6, for which the time and temperature parameters have been adapted. This standard makes it possible to simulate the residual gummy stickiness of a product. Thus, this test makes it possible to assess whether a product remaining on the machine when stopped after machining, for example left in the open air, will tend to cause a blockage phenomenon on restarting, due to the presence of sticky dried residues on the tooling.
- gummy residues is quantified by measuring the mass of water-insoluble residues after use of the composition. To do this, the composition to be tested is placed in a ventilated oven at a temperature of 90° C. for 20 hours. The mass of composition is measured before and after passing through the oven. The composition is then dissolved in osmosed water for 15 minutes at ambient temperature and with mechanical stirring at a speed of 600 revolutions/minute. The insoluble residues correspond to the gummy residues formed. These are filtered and weighed to determine the quantity in milligrams. The greater the quantity of residues, the more this means that the lubricating composition will have a tendency to form undesirable gummy residues, after its use as a lubricant in machining machines.
- Example 1 Preparation of the lubricating compositions II, C1 and C2
