Definitions
- the present invention relates to lubricating gear compositions.
- Said compositions according to the invention are biodegradable, do not bioaccumulate in organisms and do not exhibit toxicity to the environment, especially the aquatic environment.
- Ecolabel lubricants are considered lubricants that meet the environmental specifications of EAL lubricants.
- Ecolabel or EAL lubricants are used in equipment that may have interfaces and / or contacts with a user, with air and / or with water. This applies in particular to gear lubricating compositions which can be in direct contact with water and / or air and / or with humans and / or any other contact requiring biodegradable, non-toxic products.
- gear lubricant compositions for industrial or marine use must meet very specific performance specifications, particularly in terms of tribological performance and compatibility.
- the present application relates to a gear lubricating composition
- a gear lubricating composition comprising:
- At least one additive chosen from anti-wear additives, extreme pressure additives, antioxidants, anticorrosion additives, metal deactivator additives, defoamers, and their mixtures .
- lubricating composition is intended to mean a lubricating composition that meets the criteria of European Parliament and Council Regulation No. 66/2010 of 25 November 2009. This regulation makes it possible to establish the eco-label. of the European Union.
- the certification framework of the Ecological label of the European Union for Lubricants (identification number EC 51 1 revision 4 of 04/07/2016) details the criteria for Lubricants. Substances and mixtures subject to a limitation or exclusion are defined in this standard.
- the additional requirements for aquatic toxicity are specified (OECD methods 201 for algae, OECD 202 for daphnids, OECD 203 for fish).
- the biodegradability and bioaccumulation potential criteria are defined in this same reference document.
- the trimethylolpropane triester is a linear or branched C14-C20 saturated or unsaturated fatty acid tri-ester, preferably C16-C20, for example C18. More preferably, the trimethylolpropane triester is a branched C14-C20 saturated fatty acid ester, preferably C16-C20, for example C18.
- the trimethylolpropane triester is trimethylolpropane iso-stearate.
- the additives that can be used in the compositions according to the invention are LuSC-list additives or additives that make it possible to obtain a biodegradable formula that meets the Ecolabel standard or the American EAL specifications.
- Anti-wear additives and extreme pressure additives protect the friction surfaces by forming a protective film adsorbed on these surfaces.
- anti-wear additives There exists a wide variety of anti-wear additives. In a preferred manner, certain additives are both anti-wear and extreme pressure additives.
- the anti-wear and extreme pressure additives are chosen from phosphorus-free or phosulfur-free ashless additives such as, for example, phosphates, phosphorothionates, phosphonates, dithiophosphates and thio phosphates, such as dialkyl dithiophosphates.
- anti-wear additive mention may also be made of triaryl thiophosphate, carbamates and thiocarbamates.
- certain additives are both anti-wear, extreme pressure and anti-corrosion additives.
- the lubricant composition according to the invention may comprise at least one anti-corrosion additive such as an N-acyl sarcosine compound.

Furthermore, the composition according to the invention meets the various characteristic tests of gear lubricating compositions.
- the present invention also relates to the use of the lubricant composition according to the invention for gear lubrication, in particular in the marine field and in equipment having gears that may be in contact with the environment (water, air, etc,) or the Man.
- composition according to the invention is also useful for the lubrication of equipment comprising gears, in particular for the lubrication of the stern tube.
- the stern tube is the system for passing through the hull to the propeller shaft while maintaining maximum sealing.
- the present invention also relates to a method of lubricating gears implementing the lubricant composition according to the invention, that is to say comprising the lubrication of the parts in contact with a lubricant composition according to the invention.
- the present invention also relates to a method of lubricating equipment comprising gears, in particular the stern tube, comprising the implementation of a lubricating composition according to the invention, that is to say the lubrication of the internal walls of the equipment comprising gears, in particular the inner walls of the stern tube, with a lubricant composition according to the invention.
