Abstract:
A Lubricant comprises a carboxylic-acid-amide which is based on aliphatic unbranched, alicylic and/or aromatic chains with chain lengths from 2 to 60 carbon atoms.
Abstract:
A fuel oil additive for a diesel engine with a DPF, which comprises a molybdenum compound and has a function to improve combustibility of PM captured by a filter of a DPF; a fuel oil comprising the additive; a lubricating oil composition for a diesel engine with a DPF, which has a sulfated ash content of 1.0 wt % or less, a sulfur content of 0.3 wt % or less and a molybdenum content of 100 ppm or more; and a DPF device for capturing PM contained in a combustion gas ejected from a diesel engine car and removing it by burning, characterized in that it is equipped with a filter having a molybdenum compound carried thereon. The additive can be used for improving the combustibility of a PM captured by a filter of a DPF, for burning the PM with stability at a relatively low temperature, for improving the efficiency of the removal of the PM, and also for prolonging the useful life of a DPF.
Abstract:
Lubricating oils exhibiting anti rust-properties are obtained by adding to the lubricating oil an acidic anti-rust additive and an acid scavenger such as carbodiimide, in a specific sequence.
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.

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:
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).
Abstract:
Sulfur-based additives, which are essentially labile-sulfur free, are employed in lubricants and functional fluids to substantially eliminate the problem of metal corrosivity and elastomer degradation generally exhibited by sulfur-based additives.
