PROBLEM TO BE SOLVED: To provide an oil-based graphite lubricant for a plunger that is superior in dispersion stability of graphite.SOLUTION: The oil-based graphite lubricant for a plunger includes graphite as a solid lubricant, and an organic bentonite swollen by a mineral oil and a surfactant that are used as a graphite dispersant. The organic bentonite is preferably obtained by reacting a bentonite with a quaternary ammonium salt. The lubricant is prepared by a method which includes a first step of causing the organic bentonite to swell in the mineral oil, a second step of adding a surfactant, and a third step of adding and dispersing graphite.

PROBLEM TO BE SOLVED: To provide additives for lubricant for improving tribologic properties, to provide novel lubricants containing the additives, and to provide a process for the preparation thereof. SOLUTION: The lubricants contain nano particles, and the lubricants are characterized in that: the nano particles are ceramic particles which have preferably specified shapes and specified particle sizes and have specified thermal conductivity; the nano particles are dispersed in base material oil comprising natural oil, mineral oil and/or synthetic oil, ester oil or the like. The process for the preparation of the lubricants is also provided. COPYRIGHT: (C)2011,JPO&INPIT

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:
Agent for the pickling of and as an antioxidant for workpieces made of iron and steel in the case of when they are subjected to non-cutting, hot transformation. The agent is used in dry form. The agent contains: (a) 20 to 80 percent by weight of a pickling-effective compound, such as, sodium metaborate; (b) 1 to 80 percent by weight of a component, such as, graphite; and (c) zero to 79 percent by weight of at least one substance selected from group (d), (e) and/or (f). Zero to 35 percent by weight of group (d), such as, coke, can be used as substance (c) and, for example, act as antioxidants. Zero to 50 percent by weight of group (e), such as, sodium chloride, can be used as substance (c), and control the physical characteristics. Zero to 5 percent by weight of group (f), such as, ammonium chloride, can be used as substance (c) and, for example, act on the reduction of the oxides of group (a).
