Definitions
- the present invention relates to the field of lubricants and, more particularly, that of additives which can be used in formulations of industrial lubricants for gearboxes, gears, bearings, compressors, turbines, hydraulic fluids, etc. or in formulations of lubricants for working or shaping metals.
- Lubricant additives are generally classified into three main families.
- Limiting additives or lubricants which are generally compounds comprising a fatty chain and a polar group (for example, fatty acids), allow lubrication under conditions of low loads; they form a monomolecular mat on the surface to be lubricated and thus reduce friction and wear. When the friction conditions become more severe. the rise in temperature leads to a desorption of these so-called limit or unctuous additives and anti-wear (AU) or extreme pressure (EP) additives are then necessary to lubricate the contact.
- AU and EP additives are generally compounds containing phosphorus, chlorine or sulfur.
- AU additives make it possible to greatly reduce the wear of the parts in contact; EP additives can cause some wear, but they prevent welding and adhesion phenomena.
- An effective lubricant formulation must include additives which make it possible to lubricate in the three regimes: limit, AU and EP; this is called a multifunctional lubricant.
- chlorinated paraffins were widely used because of their AU and EP spectrum, but their use tends to be very reduced for reasons of toxicity.
- Sulfur compounds such as, for example, polysulfides, sulfurized olefins or sulfurized fatty substances, have been used for a long time for their EP capacity; they make it possible to lubricate under conditions of high load and / or high temperatures.
- the use of sulfur compounds alone provides good EP properties, but the wear generated is too great.
- many sulfur derivatives are not suitable for the lubrication of yellow metals (copper, copper alloys, etc.) because of their corrosive action.
- phosphorus derivatives are well known. They are generally phosphites or phosphoric esters (either triesters obtained by reaction of an alcohol on PCI 3 , or mixtures of mono and diesters obtained by reaction of an alcohol on P 2 O 5 ).
- phosphites or phosphoric esters either triesters obtained by reaction of an alcohol on PCI 3 , or mixtures of mono and diesters obtained by reaction of an alcohol on P 2 O 5 .
- the use alone of phosphorous compounds leads to a strong reduction of wear, but it does not allow to reach regimes where the friction conditions are very severe.
- a subject of the present invention is therefore a multifunctional lubricant comprising at least one phosphorus compound (A) and at least one sulfur compound (B), characterized in that compound A is a phosphoric ester of general formula:
- compound B is a polysulfide of general formula:
- y is a number ranging from 2 to 8 and R 1 represents a tertioalkyl radical having from 4 to 18 carbon atoms, the mass ratio A / B being between 0.01 / 1 and 1/1, preferably between 0.05 / 1 and 0.4 / 1.
- the invention also relates to an additive for multifunctional lubricants consisting of the mixture of at least one phosphoric ester (A) as defined above or a salt of such an ester and at least one polysulfide (B) as defined above, in an A / B mass ratio of between 0.01 / 1 and 1/1, preferably between 0.05 / 1 and 0.4 / 1.
- phosphoric esters (A) those in which k is equal to 2, m is between 2 and 6 and R is a radical containing from 12 to 18 carbon atoms, more particularly the lauryl, stearyl, oleyl or linoleyl.
- the phosphoric esters (A) which are most often mixtures of mono- and di-esters in proportions ranging from 10/90 to 90/10, can be used in the acid form or in the form of alkali, ammonium or alkanolamines.
- polysulfides (B) those in which the number is between 3 and 5 and the radical R ′ contains from 4 to 12 carbon atoms are preferred. More particularly preferred are di-tertiobutyl trisulfide, di-tertononyl pentasulfide, di-tertiododecyl trisulfide and di-tertiododecyl pentasulfide.
- the additive according to the invention can be prepared by simple mixing of the compounds (A) and (B) which are generally liquid at room temperature. In some cases, the operation can be facilitated by heating.
- the multifunctional lubricants according to the invention can be obtained by incorporating the additive according to the invention in whole oils or in soluble oils (emulsions and microemulsions), in a proportion of 1 to 100 parts of additive (preferably 2 to 50 and more particularly 5 to 20) per 100 parts of oil.
- the oils can be mineral, synthetic or of animal or vegetable origin and contain additives conventionally used in lubricants such as, for example, lubricants, corrosion inhibitors, emulsifiers, alkaline agents, etc.
- the phosphoric esters which are marketed by the applicant consist mainly of mono-esters
- the polysulphides TPS 20, TPS 32, TPS 37 and TPS 44 are marketed by the company ATOFINA
- Test 4 extreme pressure balls (ASTM D-2783):
- Test 4 wear balls (ASTM D-4172):
- the ball-disc test consists in rotating a disc at constant speed under a ball on which a constant load is applied.
- the disc and the ball are immersed in the lubricant
- a force sensor measures the coefficient of friction of the lubricated ball-disc contact.
- the test consists of immersing a polished copper plate in a test tube containing 30 ml of formulation for 24 h at 60 ° C. At the end of the test time, the plate is properly washed and compared with corroded reference slides (the classification ranging from 1 a for the least corroded to 4c for the most corroded).
- Table 2 summarizes 27 additive compositions prepared from the products in Table 1.
- compositions 6 to 15 and 17 are in accordance with the present invention
- the others do not contain a phosphorus compound (compositions 1 to 4) or no sulfur compound (compositions 5, 16, 18, 20, 22 and 24) or contain a phosphorus compound derived from a non-linear alcohol (compositions 19, 21, 23 and 25 to 27).
- compositions of Table 2 were diluted in a 100 neutral Neutral paraffin oil and the performance of the formulations thus obtained are collated in Table 3 below where the percentage of dilution indicates the proportion of additive composition in the formulation.
- Examples 31 to 33 correspond to the phosphorus compounds alone dispersed in water.
- Examples 34 to 37 are in accordance with the invention.
- Examples 38 and 39 are not in accordance with the invention.
- the additive composition 1, 2, 5 or 7 from Table 2 was then added and heated to 50 ° C. for homogenization.
