Definitions
- the present invention relates to lubricant varnish compositions based on water, glycerin and graphite fluoride, their preparation and their use.
- Solid lubricants such as molybdenum disulphide, graphite and graphite fluoride, only rarely apply as a dry powder to the surfaces to be lubricated. It is most often preferred to use them in the form of dispersions in oil, in organic solvents or in water, or also in the form of greases or pastes. On many metal parts it is even more advantageous to deposit a lubricating varnish adhering to the metal.
- varnishes based on molybdenum disulphide and heat-hardening binders, such as sugar syrups, silicones, asphalts, glycerin.
- Such varnishes are described in particular in publications of the NACA (National Advisory Committee for Aeronautics): Technical Note 2628 of February 1952 and Technical Note 2802 of October 1952.
- the particle size of the solid lubricant must be closely related to the roughness of the metal surface. The lower the roughness, the finer the particle size of the solid lubricant must be to obtain good adhesion of the varnish to the metal.
- Graphite fluorides are solid lubricants, which have many advantages over molybdenum disulfide. They have the general formula (CF x ) n , in which x can vary from around 0.8 to 1.2 and n is undetermined. When one wants to prepare lubricating varnishes based on graphite fluoride based on the teachings of the prior art, one encounters many difficulties.
- Aqueous dispersions of graphite fluoride can be prepared by grinding for example 20 parts by weight of graphite fluoride with a particle size of 5 ⁇ m in the presence of 70 parts by weight of water and 10 parts by weight of DISPERGINE CB (registered trademark of the Applicant for the sodium salt of a condensate of naphthalenesulfonic acid and formalin).
- the final particle size of the graphite fluoride in the dispersion is approximately 1 gm.
- glycerin is incorporated into the aqueous dispersion of graphite fluoride, so as to have a graphite fluoride / glycerin ratio equal to 0.4, and this composition is sprayed on aluminum or l steel, a very irregular and poorly adherent film is obtained after baking.
- compositions are obtained which, after drying for one hour at 250 ° C., form glossy varnishes, adhering very strongly to all types of metals and perfectly resistant to water. These compositions are very easy to apply by spraying and make it possible to obtain very thin films, 4 to 5 ⁇ m thick, with high lubricating power.
- the choice of heat-hardening binder is critical. If instead of glycerin, we use a sugar syrup, like the "molasse spread", we get a kind of non-spreadable and non-sprayable grease.
- the choice of dispersant, used as stabilizer of the aqueous dispersion of graphite fluoride is also critical. If the DISPERGINE CB is replaced by OLOA 246 B (trademark registered by the Company OROGIL for a calcium sulfonate) or by PLURONIC P 103 or F 88 (registered trademarks of the applicant for sequenced condensate of oxide of propylene and ethylene oxide), varnishes are obtained which have no adhesion to aluminum.
- the graphite fluoride / glycerine ratio can vary between 0.3 and 1, but preferably between 0.5 and 0.8.
- compositions (1) and (II) of Example 1 are sprayed onto ordinary steel, stainless steel and aluminum plates at various degrees of polishing, so as to obtain, after cooking for one hour at 250 ° C, varnishes having a thickness of 4 to 5 ⁇ m thick.
- the adhesion of the varnish to the metal is considered to be good to very good, and the film formed on the surface of the metal withstands the drop of water test.
- the lubricating power of the compositions (1) and (II) of Example 1 is measured on a ball-plane machine, which makes it possible to record the coefficient of friction as a function of the temperature.
- An XC 38 steel disc is polished to the chosen roughness and covered with the product to be tested. This disc, rotating at constant speed, is subjected to the pressure exerted by a fixed ball made of 100 C 6 steel.
- the lubricating power of a simple 2/1 mixture of glycerin and fluoride was measured under the same conditions. of graphite (A of Example 1) and the lubricating power of an aqueous dispersion of graphite fluoride (B of Example 1). The results obtained are reported in Table 1.
- the friction stability is good if during the measurement the 4CF variations of the friction coefficient are less than or equal to 0.01. Stability is medium if ⁇ CF ⁇ 0.02 and poor if ⁇ CF> 0.02.
- composition (I) of Example 1 is used to improve the lubrication of bearings constituted by a steel strip covered with sintered brass balls and impregnated with polytetrafluoroethylene. A single coat is enough to obtain, after drying at 250 ° C for 1 hour, a very correct varnish. In comparison, if the simple mixture A of Example 1 is used, several layers must be applied, and the resulting varnish completely lacks adhesion.
- the composition (1) of Example 1 is used to lubricate a cast aluminum device intended for the manufacture of parts of agglomerated polyurethane.
- This device consists of a cylindrical ring in which slides a tightly adjusted cylinder. While the mixture A of Example 1 gave, after cooking, a non-adherent varnish, the composition (1) sprayed inside the ring and on the cylinder gave an adherent and lubricating varnish.
- composition (1) of Example 1 was sprayed on refractory steel parts used in a brazing installation and called to withstand temperatures of 500 to 600 ° C and splashes of brazing. After drying, composition (1) gave an adherent varnish, resistant to severe conditions of use.
