Abstract:
Lubricating composition comprising fluorine oil and tricalcium phosphate. Preferably the tricalcium phosphate is used at from 1% to 40% by mass relative to the total composition. The lubricating composition of the present invention has excellent heat resistance, load resistance, fire resistance, and a long life at elevated temperatures, without using a fluororesin or the fluorine solvent to dissolve it.
Abstract:
PROBLEM TO BE SOLVED: To provide a protective film treating agent capable of forming, by a simple method for attaching it to the surface of a metallic material and then drying, a film having excellent seizing resistance and excellent rust prevention which are equal to or higher than the film formed by a chemical treatment method. SOLUTION: The protective film treating agent is obtained by incorporating an alkali silicate to be represented by the formula: M 2 O.nSiO 2 [wherein n is a number of 2-9; and M is at least one kind of Na, K, Li, and NR 4 (wherein R is an alkyl group)] into water. The incorporation of a lubricating component into this protective film treating agent can impart excellent self-lubrication performance to a film. COPYRIGHT: (C)2003,JPO
Abstract:
Provided is a grease composition with a long service life under high-temperature conditions, considerable low-evaporability, and incombustibility.The invention provides a grease composition comprising, as a base oil, an ionic liquid formed of a cation and an anion and having an ion concentration of 1 mol/dm3 or more as measured at 20° C., and a thickener, wherein the grease composition has a dropping point of 260° C. or higher.
Abstract:
The present invention relates to a lubricating composition containing an alkali metal borate. The invention further provides for a method of lubricating a device with grease or a metalworking fluid by employing the lubricating composition containing the alkali metal borate.
Abstract:
The invention relates to a lubricant composition based on modified, natural and renewable raw materials, the viscosity of which can be adjusted according to the application. The invention relates more particularly to biodegradable lubricant compositions.
Abstract:
A composition is disclosed which comprises an aryl perfluoropolyether, optionally a halogenated oil, and further optionally a thickening agent. The composition can be used as a lubricant itself or as an additive to an oil or grease lubricant and can withstand temperatures higher than 300° C. without decomposition. The halogenated oil can be a perfluoropolyether, a fluorosilicone, a polytrifluorochloroethylene, or combinations of two or more thereof. The thickening agent can be finely divided silica, boron nitride, clay, soap, poly(tetrafluoroethylene), clay, talc, silica, titanium dioxide, polydimethylsiloxane, polyurea, polyurethane, or combinations of two or more thereof.
Abstract:
A grease composition is produced by mixing a thickener comprising a fluoro resin and a second thickener component (a metallic soap, a complex metallic soap, an N-substituted terephthalamic acid metal salt, organic bentonite or a calcium sulfonate complex) into a base oil. This grease composition is excellent in heat resistance, load carring capacity, water resistance, rust protection, lubricating life and the like. A rolling apparatus filled with the above grease composition has excellent lubricating ability and is long-lived under high-temperature conditions. Moreover, a grease composition is produced by mixing a thickener comprising a fluoro resin and carbon black as a second thickener component into a base oil. This grease composition is excellent in heat resistance, water resistance, rust protection, lubricating life, electric conductivity and the like. A rolling apparatus filled with the above grease composition has excellent electric conductivity and is long-lived under high-temperature conditions.
