l bean skin 11 The lubricating composition of the present invention comprises (i) a grease, a mineral oil of lubricating viscosity, a synthetic liquid of lubricating viscosity; and a solid lubricant resin binder of about 60 to about 99.8 weight. % lubricant, and (if) from about 0.1% to about 20% intimately mixed with the lubricant. 5bsbs, and a synergistic combination of about 0.1 to about 20% SbzOs (in this process, 5bsbs to 5bzOs weight ratio is within the range of about 0.1 to 10) It is defined as a lubricating composition.

Preferably the weight ratio is within the range of 0.1 to 5 and 5 bsbs is 8 bsbs of the composition. % and more preferably the weight ratio is within the range of 0.3 to 5 and 5bsbs4 accounts for 0.5-2.0% of the composition.

The lubricant is preferably selected from mineral oils of lubricating viscosity or synthetic liquids of lubricating viscosity. . More specifically, the lubricants include silica grease, clay grease, and lithium grease. Grease or aluminum complex grease.

The method of the invention includes intimately mixing the above components of the composition.

5bsbs, and 5bzOs are premixed to form a premix and then lubricated. Preferably, it is mixed with the agent.

The premix of the present invention has a weight of 5 bsbs vs. Sb*Os within the range of 0.1 to 10. It is a mixture of 5bsbs and 5btOs in quantitative ratio, and it is also used as a lubricant additive. It is defined as a useful mixture. Preferably, the weight ratio is within the range of 0.3 to 5. Ru. Preferably, 5bsbs, and hissb, o, is 0.01 to about 1o0 micro fine particles with a particle size preferably in the range of 0.1 to 10 microns. It is in the form of a divided powder.

The present invention uses a premix to lubricate surfaces adapted for frictional contact. It includes using. More specifically, this aspect of the invention A lubrication agent having an effective amount of the above 5bSbS-/5b20s mixture adjacent to the lubrication agent. defined as a contact surface that is This mixture can be separated depending on the specific situation. Can be bonded to a surface with a dispersed resin or incorporated into the surface and can be dispersed.

feminine 5゛ho Extreme pressure additives, anti-wear additives and anti-friction additives included in the synergistic mixture of the invention Abrasive additives are generally in particulate form, ie, generally from 0.01 to about 100 microns. finely divided particles having a particle size within the range of 0.1 to about 10 microns, preferably within the range of 0.1 to about 10 microns. It is blended into lubricant compositions as a crushed powder.

The compositions of the invention can be applied to a variety of materials such as metals, alloys, ceramics, plastics, Useful for lubricating contact surfaces of cermets and other materials; The surface may be of the same or different materials; What is essential is oil, grease and solid lubricants with improved extreme pressure properties and load carrying capacity. agent mixtures and these are present in oils, greases or solid resin binders. The synergistic mixture of the invention is preferably present in an amount of 0.2 to about 40% by weight of the composition, preferably 1.0 to about 20% by weight of the composition. It is prepared by blending in % by weight.

The following example is illustrative of the invention, in which thioantimonylate Preparing a synergistic mixture of thymony and antimony dioxide and incorporating it into a lubricating composition It has been tested as an additive.

One what'22'- Lithium derived from mineral oil-based liquids thickened with 12-hydroxystearate Mugrease with antimony thioantimonate, antimony dioxide and various proportions of antimony thioantimonate and antimony dioxide, respectively. Each group Evaluate the greases with a shell four-ball EP tester and measure the seizure point of these greases. (ASTM D2596), and the test results are shown in Table 1, with four weight ratios. The seizure point of the grease of Example 4 containing 1% of 5bSbS4/Sb*Os mixture is 5 Superior to grease containing 1% of either bsbs or Sb*Os alone The synergistic effect is recognized as the performance is shown to be similar.

-Dish "22-age"- Friction and wear resistance of synergistic mixtures of antimony thioantimonate and antimony dioxide To illustrate the properties, a sample containing 2% abrasive coarse particles having an average particle size of 50 microns Lithium grease (General Motors Corporation A/C division) was used as the base grease.

5bsbs, , sb*o, and various ratios of 5bsbs and Sb*Os It was formulated separately into a base grease. We evaluated the friction and wear resistance of these greases. A Shell four-ball EP tester was used to test the results. The experimental data are shown in Table H, using each set. Both the average wear scar diameter and weight loss were obtained for the steel balls. The smallest wound diameter and The grease that provides the best performance as shown by the lowest weight loss and , containing a 5bSbS4/5b20s mixture in a weight ratio of 4. To further illustrate the friction and wear resistance of the synergistic mixture of 4 and 5bxOs, Finely divided high friction iron ore fine powder (Sidbec Normjnes, Port Cartier, Canada) was used as the base grease. 5bSbS, , 5bzOs and various ratios of 5bSbS4/5bxOs mixtures were separately prepared. As in Examples 6 to 10, the flatness of these greases Uniform wound diameter and weight loss were obtained. The results are shown in Table ■0 5b as defined in the present invention Grease with SbS4/5btos ratio is 5bsbs, or 5btos. It provides better performance than grease containing either bt03 alone. are clearly illustrated.

The 5bSbS4/5bzOs mixture is made of polyamide or polyphenylsulfide. A similar synergistic lubrication effect was observed when dispersed in a resin binder. Can be done.

The 5bSbS4/5bzOs mixture can be used alone or on surfaces requiring lubrication. A lubricant composition by itself by applying in combination with other solid lubricants and can be used. Such use is subject to extremely high operating temperatures. of particular application where the base grease or oil decomposes at the operating temperature. I can do it. This mixture can also be used with resin-type binders or in the case of pigments. be held closely adjacent to the contact surface by incorporating directly into the surface, such as can be done. Many applications apply to virtually all types of surfaces that require lubrication. Possible applications 0 For example, sliding surfaces on car sunroofs (avoiding grease) ) can be produced in this way, but in this case, premix The polymer may be resin-bonded to the surface or incorporated into the surface in a pigment-like manner.
