PCT No. PCT/CA97/00658 Sec. 371 Date Jun. 22, 1999 Sec. 102(e) Date Jun. 22, 1999 PCT Filed Sep. 11, 1997 PCT Pub. No. WO98/13445 PCT Pub. Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.
Abstract:
The potassium titanate of the present invention comprises particles of a diameter of 3 mu m or less and a length of 5 mu m or more with a ratio of the length to the diameter of 3:1 or more, at a content in number of 3% or less, with no hazardous particles contained therein from the respect of health and hygiene. The potassium titanate can be produced by heating a Ti source and a K source as the raw materials to a final TiO2:K2O ratio of 5.5:1 to 6.5:1 at a temperature elevation rate of 20 DEG C./min in the temperature region above 800 DEG C.
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant composition, which can be used for various purposes and can reduce an electric power and fuel consumption and further increase cooling efficiency and suppress the lowering of developped output when it is used in a compressor or an internal combustion engine and the like. SOLUTION: The lubricant composition is a lubricity base oil containing the primary ultrafine powder of a metal and the secondary ultrafine powder of a mineral. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
An improved lubricating oil composition comprising a major amount of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount by weight of at least one of certain co-polymers derived from the polymerization of (1) an N-vinyl-pyrrolidone, and (2) an oil-soluble acrylic ester.
Abstract:
Provided is a thermally-curable heat-conductive silicone grease composition which has high shape-retaining property in an early stage even when the viscosity of the composition is low (i.e. the composition is easy to apply) in the early stage, and which becomes soft (has low hardness) after being cured. The thermally-curable heat-conductive silicone grease composition comprises, as essential components: (A) organopolysiloxane having a viscosity of 100 to 100,000 mPa·s at 25°C and containing at least one alkenyl group per molecule; (B) organopolysiloxane represented by general formula (1)
(wherein R 1 represents a monovalent hydrocarbon group; R 2 represents an alkyl group, an alkoxyalkyl group, an alkenyl group or an acyl group; n represents 2 to 100; and a represents 1 to 3); (C) organohydrogenpolysiloxane containing at least two hydrogen atoms each directly bound to a silicon atom per molecule; (D) catalyst selected from the group consisting of platinum and platinum compounds; (F) heat-conductive filler having a heat conductivity of 10 W/m·°C or more; and (G) silica micropowder.
