- the present invention relates to silicone greases based on organometallic soap with a strong cohesion especially cold. It also relates to the process for preparing said greases and their use in particular in the field of the automotive industry.
- Examples of driving devices include: a clutch cable, a gearbox, a starter of a motor vehicle.
- the essential objective of the present invention is to provide a silicone grease that may have a high flow threshold greater than 600 Pa at -40 ° C.
- Another objective is that of proposing a silicone grease which may have such a high cold flow threshold, without altering the standard properties of the grease, in particular its consistency at ambient temperature of 23 ° C., its low volatile content and a high good resistance to exudation (or PT) hot, that is to say at a temperature within the range of from 100 ° C to 170 ° C.
- Yet another object is to provide such silicone greases which can be prepared by a method known to those skilled in the art and under low cost conditions.
- the subject of the present invention is therefore a silicone grease having a strong cohesion comprising: at least one oily diorganopolysiloxane polymer,
- paraffin is non-halogenated, in particular non-chlorinated and consists essentially of hydrocarbons, preferably linear, derived from the distillation of petroleum, and is selected from the group consisting of: short chain paraffins C 1O - C1 3, the medium-chain paraffins Cu-C 17 and the long chain paraffins C 1 S-CsO.
- the greases according to the present invention have a high flow threshold that is to say greater than 1000 Pa and this even at -40 0 C while offering technical characteristics in terms of, for example, penetration, content of volatile compounds , held to exudation which are at the desirable level.
- Oily diorganopolysiloxane polymers which are the basic constituents of fats, correspond to the general formula:
- linear polymers thus consist essentially, apart from the terminal units, of a succession of siloxyl units of formula (R) 2 SiO 2Z 2 ; however, the presence of a small amount of other siloxyl units, such as those of formula S1O 4/2 ("Q" units) and (R) SiO 3/2 ("T” units), is not excluded by not more than 1% of the number of (R) 2 SiO 2/2 units ("D" reasons).
- alkyl radicals having 1 to 13 carbon atoms such as in particular the methyl, ethyl, propyl, butyl, pentyl, hexyl, 2-ethylhexyl, octyl, decyl and dodecyl radicals;
- aromatic radicals with a single benzene nucleus having from 6 to 10 carbon atoms such as, in particular, phenyl, totyl, xylyl, ethylphenyl, cumenyl and butyphenyl radicals, these radicals possibly comprising one or more substituents comprising chlorine.
- At least 45% by number of the hydrocarbon radicals R are alkyl radicals.
- These diorganopolysiloxane polymers are oily liquids whose viscosities range (according to the nature of the radicals R and the values of n) substantially from 100 mPa.s to 500,000 mPa.s at 25 ° C. They are mostly manufactured industrially by silicone manufacturers; moreover, their preparation appears in the chemical literature for example in the French patents 978 058, 1 025 150 and 1 108 964.
- oily diorganopolysiloxane polymers preferably used, alone or as a mixture, are those represented by formulas (III) to (VII).
- the silicone greases according to the invention contain, as gelling agent, organometallic soaps.
- the gelling agents used to form the fat may be fatty acid soaps.
- the saponifiable material may be derived from higher fatty acids containing 10 to 32 carbon atoms, these acids may be hydroxylated or non-hydroxylated and may be saturated or unsaturated.
- Non-hydroxylated fatty acid soaps are preferably used, such as in particular: capric, lauric, myristic, palmitic, stearic, arachidic, behenic, lignoceric, myristoleic, palitoleic, oleic, linoleic and erucic acids; fatty acids of cottonseed oil, palm oil, hydrogenated fish oil mixed or not, and / or their glycerides, such as, for example, lard, beef, rapeseed oil, palm, menhaden, herring; acids from the oxidation of petroleum oil and waxes; resinous acids; heavy oil acids; abietic acids; naphthenic acids or sulphonic acids.
- the saponification agent used to make the soap may be a metal compound of Li, Na, K, Cs, Mg, Ca, Sr, Cd, Zn, Pb, and Co and preferably an oxide, a hydroxide and a carbonate of water.
- a metal compound of Li, Na, K, Cs, Mg, Ca, Sr, Cd, Zn, Pb, and Co preferably an oxide, a hydroxide and a carbonate of water.
- Soap mixtures can be used and these soaps can either be prepared in situ or made in advance to form the fat.
- soaps used alone or in mixtures are: lithium soap of stearic acid; lithium fatty acid soaps of hydrogenated fish oil; sodium soap of stearic acid; sodium soap of oleic acid; potassium soap of oleic acid; calcium soap of stearic acid; stearic acid barium soap; barium soaps of stearic and oleic acids in admixture; lithium and sodium stearic acid composite soaps.
- Soaps that are especially well-suited for use alone or in combination are stearic acid lithium soap and lithium and sodium stearic acid composite soaps.
- the soap content (s) of the greases according to the present invention represents 10 to 30% by weight and according to a preferred embodiment of 15 to 25% by weight.
- auxiliary additives the purpose of which is to facilitate the preparation of greases (better dispersion of the fillers, reduction of the mixing period) and / or to improve their internal cohesion and / or to bring a color
- oily diorganopolysiloxane polymers and organometallic soaps can be incorporated with oily diorganopolysiloxane polymers and organometallic soaps.
- additives may be mentioned, as an indication: the polyalkylene glycols; boric acid and alkyl borates; pentaerythritol; hydroxylated diorganopolysiloxane oils of low viscosity ranging from 10 to 500 mPa.s at 25 ° C; colored pigments.
- the total amount of these additives, when used, is in the range of generally 1 to 8% by weight based on the weight of the fat.
- the non-chlorinated paraffins which form part of the silicone grease composition according to the present invention can be chosen from among numerous organic compounds of this type described and marketed.
- Such compounds are liquid at atmospheric pressure and at room temperature (23 ° C); they generally have a viscosity in the range of from 5 to 1000 mPa.s, preferably from 5 to 500 mPa.s.
- the non-chlorinated paraffins used are preferably non-chlorinated paraffins with C 14 -C 17 medium chains and long C 18 -C 5 O chains.
- non-chlorinated paraffins which are especially suitable, mention may be made in particular of the products sold by JANEX under the trade names: 1040; 1080.
- the content of non-chlorinated paraffin (s) of the fats according to the present invention represents 2 to 10% by weight and preferably 2 to 7% by weight.
- the fat is prepared by melting / recrystallizing the soap in the oily diorganopolysiloxane polymer (s) and incorporating at least one non-chlorinated paraffin either before or after the melting / recrystallization step, but preferably after the melting / recrystallization step and cooling of the fat.
- This procedure is carried out in apparatus designed for mixing viscous mixtures; for example, are well suited for this preparation of mixers and kneaders.
- the grease may be grinded as required, for example by operating in a roll mill or in a colloid mill to adapt the rheology and / or the appearance of the grease to the desired applications.
- 510V100 oil poly (dimethyl) (methylphenyl) siloxane copolymer having a viscosity of 100 mPa.s at 25 ° C and comprising 15% by weight of Si (C 6 H 5 ) (CH 3 ) O 2 Za siloxyl units ;
