- the present invention relates to organosilicon pastes or fats having in particular a flow threshold and a resistance to degradation in basic, acid and saline medium, to their preparation process and to their use in particular in the food sector (lubrication, grease tap, etc.).
- Silicone greases are usually used for the lubrication of parts working under low stresses, such as valves.
- the silicone pastes also serve as filling pastes, in particular for protecting electrical circuits, or as a shock absorber.
- patent application JP-A-52/146405 of December 6, 1977 proposed a lubricating grease composed of a lubricating oil of low viscosity (in the examples between approximately 110 and 220 mPa.s at 37.8 ° C ), which can be a mineral oil, a di-ester oil, a silicone oil or a mixture of oils of different natures, an antirust and calcium carbonate.
- the composition may contain up to 50% by weight of calcium carbonate, but preferably between 20 and 30%.
- This document which targets different kinds of fats which differ in the nature of the oil, mainly targets mineral oils. No example relates to the application to silicone oils
- silicone pastes and greases are generally composed of a diorganopolysiloxane oil free of aliphatic unsaturations, of combustion silica and of a thixotropic system which can be, for example, a combination of boric acid and polyols, polyethers, in particular polyoxyalkylated glycols, or also an ⁇ , ⁇ -dihydroxylated silicone oil of low molecular weight.
- the silicone pastes and greases are generally prepared by a hot process, consisting in mixing the various constituents for several hours at approximately 120 ° C.
- Patent DE-A-2 535 304 proposed incorporating from 30 to 70% by weight of natural carbonates in a silicone resin associated with a curing agent. Natural calcium carbonate is preferably hydrophobic and of particle size less than 10 ⁇ m
- Patent JP-A-4/307058 proposes a hydrophobic liquid based on oil or silicone gum to which natural calcium carbonate is added, the particle size of which is around 45 ⁇ m
- the present invention has the essential objective of proposing new silicone pastes and greases which may have a high flow threshold and stable over time even at high temperature and which can be prepared by a cold process and under conditions of low cost price and clearly lower than the cost price of silicone pastes and greases of the prior art
- Another objective essential of the invention is to propose such pastes and fats having improved resistance in basic and acidic medium and in a marine environment.
- Another essential objective of the invention is to propose such pastes and fats which can be used without risk in the food industry
- Yet another objective of the invention is to provide such pastes and fats whose flow threshold can be adjusted in a simple and reproducible manner to a value at least equal to 20 Pa, this property being measured according to the indications given in the detailed description.
- the present invention therefore relates to an organosilicon paste or fat comprising at least one oily diorganopolysiloxane polymer having a dynamic viscosity at 25 ° C at least equal to 500 mPa s and at least one carbonate of alkali or alkaline earth metal, in the absence of a thixotropic agent proper, that is to say of a purely thixotropic agent of the prior art, the carbonate having a particle size (mean particle diameter) less than or equal to 0.5 ⁇ m and a high BET specific surface area greater than 5 m 2 / g, and being present in an amount of at least 20%, preferably more than 30%, preferably 30 to 70%, by weight relative to the total composition, and more preferably from 35 to 45% by weight
- the Applicant has found that, under the conditions of the invention, it was possible to replace the usual fillers and thixotropic agents with a single compound which is a carbonate as defined above, and the use of which allows the Once implemented at low temperature and ensure the mechanical properties of the pasta and fat thus prepared and give them a high flow threshold and stable over time even at high temperature.
- some of the carbonates according to the invention are perfectly suitable for use in the food sector. Another advantage results in the fact that the paste or fat obtained has an improved smoothness.
- the implementation can be carried out between 5 and 40 ° C, advantageously at room temperature (between 20 and 25 ° C approximately).
- the oily polymer will preferably have a dynamic viscosity of between 800 and 30,000 mPa.s and more preferably still between 900 and 15,000 mPa.s.
- the carbonate according to the invention will preferably have an average particle diameter or particle size less than or equal to 0.1 ⁇ m, more preferably between 0.01 and 0.1 ⁇ m, and preferably a BET specific surface ranging from 10 to 70 m ⁇ / g, preferably 15 to 30 m 2 / g.
- It will preferably be an alkaline earth metal carbonate, preferably calcium.
- carbonate according to the invention is meant a carbonate which, as is the case with carbonates used in industry, contain a certain amount of residual moisture of hydration, which is generally of the order of 0.1 at 0.5%.
- the viscosity of the oils is a dynamic Newtonian viscosity at 25 ° C. measured using a BROOKFIELD viscometer according to the indications of standard AFNOR NFT 76102 of May 1982.
- the BET specific surface is determined according to the BRUNAUER, EMMET, TELLER method described in "The Journal of American Chemical Society, Vol. 80, page 309 (1938)" corresponding to standard AFNOR NFT 45007 of November 1987.
- the carbonates according to the invention are treated, in particular with carboxylic fatty acids such as for example stearic acid.
- the flow threshold sees its value increase with the carbonate content, so that a person skilled in the art can easily adapt the composition to the intended applications and at the desired flow thresholds and obtain very high flow thresholds.
- the oily diorganopolysiloxane polymers which are the basic constituents of pasta, generally correspond to the following formula: R 3 Si (OSiR2) n OSiR 3 in which the symbols R, identical or different, represent hydrocarbon radicals having no aliphatic unsaturations and having at most 10 carbon atoms and the symbol n represents any number defined so as to obtain the viscosities defined above end units, these linear polymers thus essentially consist of a succession of units of formula R2SiO, however, the presence of a small quantity of other units, such as those of formulas Si ⁇ 2 and RSiO j 5, is not excluded in particular at a rate of at most 1% relative to the number of R2SiO units
- hydrocarbon radicals represented by the symbols R are chosen from - alkyl radicals having from 1 to 8 carbon atoms such as methyl, ethyl, propyl, butyl, pentyle, hexyl, 2-ethylhexyl radicals
- hydrocarbon radicals R are methyl radicals. They are for the most part manufactured industrially by the manufacturers of silicones
- ni, n2 + n3 and n4 + n5 will be between 200 and 1000
- the present invention makes it possible to obtain pasta or fat having a flow threshold greater than 20 Pa and capable of reaching and exceeding values as high as 500 Pa, and this in a reproducible manner It also makes it possible to fulfill the other stated objectives upper
- the pastes or fats according to the invention can also incorporate other mineral fillers or other usual additives depending on the final application.
- the invention also relates to a process for the preparation of these pastes and fats, in which they are used at low temperature, preferably between 5 and 40 ° C.
- the carbonate is gradually added to the silicone oil with stirring and / or it is mixed at room temperature, in particular for a few hours, then, optionally, it is degassed under vacuum.
- the invention also relates to the use of carbonate according to the invention to charge a silicone paste or grease, in particular for food use, and to give it a flow threshold, the carbonate being present in the quantities indicated above.
- oils and carbonates approved for food contact must be used according to the legislation in force. As regards oils, they are in particular completely methylated.
- the calcium carbonate level was varied between 20% and 40% by weight in the dough. Different viscosities of polydimethylsiloxane oil with terminal trimethylsilyl units have been tested: between 1000 and 10 000 mPa.s. All the tests were carried out without adding a thixotropic agent or combustion silica. Each time a white, smooth paste is obtained, having a flow threshold whose value increases with the rate of precipitation carbonate.
- a paste is also prepared under the same conditions (always with the same oil) by replacing Calofort S with ground natural carbonate BLR3 from OMYA (average diameter 5 ⁇ m and BET surface 2 m 2 / g).
- the paste contains 40% BLR3 carbonate.
- the measurements are carried out using a Carri-med CS 100 constrained rheometer (sold by the company Carri-med) at 25 ° C, with a cone / plane geometry, diameter cone 2 cm, angle 1 °, according to the manufacturer's specifications in "Operations manual for the Carri-med CSL rande of rheometers using version 5.0 software"
- the threshold is calculated according to the Casson model according to the specifications of Carri-med.
- the dough is brought from 100 ° C to 200 ° C in a ventilated oven. Up to 150 ° C, there are no differences in properties (appearance, consistency) At 175 ° C, there is a change in surface appearance, but no change in consistency. After 24 hours at 200 ° C, the evolution is identical to that observed at 175 ° C, on the other hand, after 100 hours at 200 ° C, there is a very significant hardening on the surface and a thickening of the heart of the dough.
- this silicone oil is introduced and calcium precipitation carbonate (Calofort S® by Rhône Poulenc) is gradually added.
- the mixture is mixed for 3 hours until a homogeneous white paste is obtained. It is degassed under vacuum (30 mm of Hg) for 5 minutes. A fat containing 35% Calofort S is thus prepared.
- This grease has a Casson flow threshold at 25 ° C of 160 Pa.
- This new grease can be used for the lubrication of drinking water taps.
