Abstract:
The invention concerns a lubricating composition, in particular for swaging, consisting of a suspension in water of a mixture of phospholipids and an organic or mineral basic compound. For example, the composition contains 80 wt.% water, 10 wt.% phospholipids brought in the form of soja bean lecithin, and 10 wt.% of calcium hydroxide or stearylamine as basic compound. Among other advantages the lubricant can be eliminated by means of an aqueous solvent, and is easily biodegradable.
Abstract:
The invention is a lubricant concentrate composition, use solution, and method of use. The lubricant includes amine compounds of the formula R1 - O - R2 - NH2, R1 - O - R2 - NH - R3 - NH2, and mixtures thereof, wherein R1 may be a linear C6-C18 alkyl, R2 may be a linear or branched C1-C8 alkyl, and R3 may be a linear C1-C8 alkyl, and a corrosion inhibitor. The lubricant composition preferably includes a polycarboxylic acid as a corrosion inhibitor. The composition may also include a hydrotrope, stabilizer, and a surfactant to provide detergency to the composition upon dilution and use. The invention also includes a lubricant use solution resulting from dilution of this concentrate.
Abstract:
A lubricating composition comprising a base oil of mineral and/or synthetic origin in combination with a friction-reducing additive combination comprising molybdenum disulphide, zinc naphthenate and one or more metal dithiophosphates, and optionally one or more metal dithiocarbamates. A lubricating grease comprising such a composition in combination with a thickener, which may be a urea compound, a simple lithium soap or a lithium complex, is particularly suitable for lubricating constant velocity joints such as constant velocity ball joints.
Abstract:
A fibrous grease comprising a base oil and a fibrous diurea thickener comprising the reaction product of toluene diisocyanate, a fatty aliphatic amine and an alkylphenyl amine.
Abstract:
A lubricant composition comprises at least 0.1 % by weight of substantially spherical particles of a hard, abrasion-resistant and fracture-resistant, thermally stable and chemically inert material, and up to 99.9 % by weight of a supporting vehicle. The particles are preferably of silica-alumina ceramic material, and preferably have an average diameter of less than 250 mu m. Lubricants are suitable for most applications, but are especially useful for conditions of high temperature and pressure.

Date Nov. 28, 1991.A flame retardant grease composition comprising a lubricating base oil, a thickener selected from a simple or complex soap of lithium, calcium or sodium, and a flame retardant additive selected from an oxide, hydroxide, carbonate, bicarbonate, hydrogen carbonate or sulphate of an alkali metal or alkaline earth metal, for example calcium oxide, potassium carbonate, potassium hydrogen carbonate or potassium sulphate, or a mixture of two or more thereof.
Abstract:
The title lubricant composition comprises a base oil or base grease and a specified amount of a heat insulating agent comprising (A) an inorganic compound undergoing endothermic melting at temperatures of 1200 DEG C or below and (B) an inorganic powder which neither melts nor decomposes at temperatures of 1200 DEG C or below and which has a thermal conductivity of 0.01 cal/cm.s. DEG C or less and a friction coefficient of 0.7 or less at room temperature added alone or as a combination. This lubricant composition has an excellent heat-insulating effect and is effective in preventing occurrence of thermal crown of working rolls.
Abstract:
A process for applying and bonding a solid lubricant on a substrate whose surface has depressions and pores. The process comprises depositing fine solid lubricant particles on the surface of a substrate to be lubricated in excess of a quantity sufficient to fill essentially all depressions and pores on the substrate surface, and thereafter burnishing the substrate to distribute and bond the lubricant particles on the substrate. Such burnishing of the substrate can be accomplished during its moving contact with another substrate during intended use. Maintenance of lubricity can be accomplished by depositing additional lubricant particles on the substrate and thereafter burnishing, and can be performed while the substrate is in moving contact with another substrate whereby this moving contact performs the burnishing operation.
Abstract:
A wax-based lubricant compounded for use as a bullet lubricant but also useful as an additive to greases and oils for general lubricating usage. The lubricant comprises a combination of petroleum and silicone oil metallic soap greases, beeswax and graphite and molybdenum disulfide.
Abstract:
Water-based metal-containinig organic phosphate compositions which are useful as corrosion-inhibiting coating compositions, metal working lubricants and drilling fluids for well-drilling operations. These compositions comprise: (A) water or an aqueous drilling mud; (B) an overbased non-Newtonian colloidal disperse system comprising (B) (1) solid metal-containing colloidal particles predispersed in (B) (2) a dispersing medium of at least one inert organic liquid and (B) (3) at least one member selected from the class consisting of organic compounds which are substantially soluble in said dispersing medium, the molecules of said organic compound being characterized by polar substituents and hydrophobic portions; and (C) a metal-containing organic phosphate complex derived from the reaction of (C) (1) at least one polyvalent metal salt of an acid phosphate ester, said acid phosphate ester being derived from the reaction of phosphorus pentoxide or phosphoric acid with a mixture of at least one monohydric alcohol and at least one polyhydric alcohol, with (C) (2) at least one organic epoxide. These compositions preferably include an effective amount of (D) an alkali or an alkaline earth metal salt of an organic acid, (E) a carboxylic acid and (F) an N-(hydroxyl-substituted hydrocarbyl) amine to enhance the dispersion of components (B) and (C) with said water or drilling mud (A).
