- sulfurous fat At a given amount of active sulfur at 150 ° C, the combination of two different sulfur-containing fatty acid esters, in particular a methyl ester of sulfur fatty acid and a fatty acid triglyceride sulfur, improves the extreme-pressure performance because the sulfur is not released in the same way.
- the less clogged ester, such as the sulfurized fatty acid methyl ester will release the active sulfur faster, then the more congested ester, such as sulfur fatty acid triglyceride will take over.
- the sulfur-containing fatty acid esters used in the present invention are commercially available products, for example from PCAS, King Industries, Dover, Magna, Arkema and Rhein Chemie suppliers.
- the grease compositions according to the invention comprise at least one fluoropolymer or fluoropolymer, an essential element of the invention to obtain good extreme-pressure performance.

- the grease composition according to the invention comprises from 1 to 10% by weight of fluoropolymer, relative to the total mass of fat composition, preferably from 2 to 8%, more preferably from 3 to 5%. A smaller amount of fluoropolymer will not achieve good extreme pressure performance, a larger amount will have a negative impact on the environment.
- the fluoropolymers used in the present invention are commercially available products, for example from suppliers Dupont, Solvay, Maflon, Xeon, Shamrock.
- the grease composition according to the invention comprises at least one base oil of renewable origin based on a polyol ester.
- the polyol esters which can be used as base oils are diesters, triesters, tetraesters or complex esters comprising more than four ester functions.

- ester base oils are chosen for their negligible impact on the environment, unlike the petroleum-based base oils conventionally used.
- the use of such polyol ester base oils has a negative impact on the extreme-pressure properties, since these polyol ester base oils tend to also go to the surface of the lubricated parts and are competition with other additives, hence the use of the specific combination of fluoropolymer and fatty acid ester sulfur.
- the polyol ester base oil or the polyol ester base oil mixture has a kinematic viscosity at 40 ° C of between 3 and 2000 cSt (ASTM D445), preferably between 10 and 1500 cSt, more preferably between 20 and 1000 cSt, more preferably between 40 and 500 cSt, even more preferably between 50 and 200 cSt.
- These viscosity ranges, in particular from 50 to 200 cSt make it possible to obtain a good compromise between extreme pressure performance and biodegradability.
- the base oils used in the present invention are commercially available products, for example from Uniqema, Croda, Oléon, Akzo, Nyco suppliers.
- the grease compositions according to the invention are thickened with fatty acid metal soaps, which may be prepared separately, or in situ during the manufacture of the grease (in the latter case, the fatty acid is dissolved in the grease). base oil, then add the appropriate metal hydroxide).
- thickeners are commonly used products in the field of fats, readily available and inexpensive.
- Greases thickened with fatty acid metal soaps have a very good mechanical stability, compared, for example, with greases comprising polyurea thickeners, which allows easy use in applications where the grease is in a chamber unconfined.
- the polyureas are prepared from isocyanate, an extremely toxic compound. It is therefore not desirable to use thickeners based on polyureas to obtain a biodegradable fat, non-toxic and free of products classified according to the CLP Regulation (EC No 1272/2008).
- the grease according to the invention is therefore free of thickeners based on polyurea and therefore comprises only metal fatty acid type thickeners.
- long-chain fatty acids typically comprising from 10 to 28 carbon atoms, saturated or unsaturated, optionally hydroxylated.
- the long-chain fatty acids are, for example, capric, lauric, myristic, palmitic, stearic, arachidic, behenic, oleic, linoleic and erucic acids, and their derivatives. hydroxylated. Hydroxystearic acid 12 is the most well-known derivative of this category and is preferred. Lithium 12-hydoxystearate is the preferred thickener.
- These long-chain fatty acids generally come from vegetable oils, for example palm oil, castor oil, rapeseed oil, sunflower oil, ... or animal fats (tallow, whale oil, etc.).
- Simple soaps can be formed using one or more long-chain fatty acids. Simple soaps are preferred over complex soaps because they are more easily biodegradable and non-bioaccumulative.
- So-called complex soaps can also be formed by using one or more long-chain fatty acids in combination with one or more short-chain hydrocarbon carboxylic acids comprising at most 8 carbon atoms.
- the saponification agent used to make the soap may be a metal compound of lithium, sodium, calcium, aluminum, preferably lithium and calcium, and preferably a hydroxide, oxide or carbonate of these metals.
- One or more metal compounds may be used in the greases according to the invention. It is thus possible to associate lithium soaps, combined with calcium soaps to a lesser extent.
- the metal soaps are used at levels of the order of 1 to 20% by weight, relative to the total mass of the grease composition, preferably from 2 to 15%, preferably from 4 to 12%.
- the greases according to the invention are manufactured by forming the metal soap in situ or by using a preformed soap.
- the method of preparing the fat by forming the metal soap in situ is as follows.
- One or more long chain or short chain fatty acids are dissolved in a fraction of the base oil or base oil mixture at a temperature between 80 ° C and 90 ° C.
- This fraction is generally of the order of 40% to 60% by weight of the total amount of oil contained in the final fat.
- Metallic compounds preferably of oxide, hydroxide or metal carbonate type, are then added at the same temperature.
- the preferred metal of the compositions according to the invention is lithium, possibly combined, to a lesser extent, with calcium.
- the saponification reaction of the long chain or short chain fatty acids is allowed to proceed with the metal compound (s) at a temperature between 80 ° C and 90 ° C.
- the formed water is then evaporated by baking the mixture at a temperature of about 100 ° C to 200 ° C.
- the grease is then cooled by the remaining fraction of base oil.
- the fluorinated polymer and the sulfur fatty acid ester and any other additives are then incorporated at about 80 ° C.
- the method of preparing the fat with the preformed metal soap is identical, except that there is no saponification reaction since the soap is already formed. These preparation methods are well known to those skilled in the art.
- the consistency of a grease measures its hardness or fluidity at rest. It is quantified by the depth of penetration of a cone of given dimensions and mass. The fat is previously subjected to mixing. The conditions for measuring the consistency of a grease are defined by ASTM D 217.
- the fats are divided into 9 classes or 9 NLGI grades (National Lubricating Grease Institute) commonly used in the field of fats. These grades are shown in the table below.
- the greases according to the invention have a consistency of between 220 and 430 tenths of a millimeter according to the ASTM D217 standard, to cover the grades 00, 0, 1, 2 and 3.
